<strong>The</strong> Institute of<br />

Cancer <strong>Research</strong><br />

We are delighted to present our <strong>Annual</strong> <strong>Research</strong><br />

<strong>Report</strong> for <strong>2004</strong>, which records another year of<br />

important achievements and significant progress<br />

in cancer research. It contains in-depth reviews of<br />

recent, exciting developments in several areas of our<br />

work, and provides addresses for various web resources<br />

which give comprehensive information on all aspects<br />

of our activities.<br />

<strong>The</strong> Institute of Cancer <strong>Research</strong> and <strong>The</strong> <strong>Royal</strong><br />

<strong>Marsden</strong> NHS Foundation Trust form the largest<br />

Comprehensive Cancer Centre in Europe, and one of the<br />

largest in the world, which has an outstanding national<br />

and international reputation. Our mission, “to relieve<br />

human suffering by pursuing excellence in the fight<br />

against cancer”, is carried out within a framework of<br />

activities in research and development, education and<br />

training, and the treatment and care of people affected<br />

by cancer. We work, like other world-class centres of<br />

excellence, in a truly international context and in<br />

partnership with many research institutions and<br />

funding agencies.<br />

<strong>The</strong> availability of the sequence of the human<br />

genome, and of the many other genomes which help us<br />

to understand the meaning of the blueprint that makes<br />

each of us, has enormous implications for cancer<br />

research. It means that we can now systematically<br />

identify all of the genes involved in the progression from<br />

a normal cell to a tumour cell. <strong>The</strong> challenge for the<br />

future is to exploit this genetic information for the<br />

benefit of cancer patients and our joint scientific<br />

strategy seeks to put in place the skills and resources

necessary to do this. This is entirely appropriate since it<br />

was our researchers, Professors Peter Brookes and<br />

Philip Lawley, who, some forty years ago, first showed<br />

that chemicals that cause cancer act by damaging DNA,<br />

the stuff of which our genes are made. This heritage<br />

continues with the Cancer Genome Project, led by<br />

Professor Mike Stratton, and undertaken in partnership<br />

with the Wellcome Trust’s Sanger Institute. It will provide<br />

us, for the first time, with a complete description of the<br />

genetic alterations which cause the disease, and the<br />

initial results are hugely exciting.<br />

Our joint research strategy seeks to exploit this<br />

information in three areas: genetic epidemiology,<br />

molecular pathology and therapeutic development.<br />

In genetic epidemiology, information from the Cancer<br />

Genome Project and other genetic analyses will be used<br />

in very large, population-based studies to try to discover<br />

the environmental and lifestyle factors that contribute to<br />

the development of cancer. Some we know, smoking<br />

being the most obvious, but for many cancers our<br />

present understanding of causation is rudimentary.<br />

Our work in molecular pathology will use the genetic<br />

knowledge to devise not only new and more sensitive<br />

ways of detecting the disease earlier but also much<br />

more precise ways of staging its progression, with<br />

consequent benefit to patient management. Knowing all<br />

the mutations in a particular tumour will help to identify<br />

the molecular targets for therapeutic intervention. Our<br />

strategy in therapeutic development will target these<br />

precisely defined molecular abnormalities, and it is<br />

greatly enhanced by substantial increases in hospital<br />

facilities for imaging, radiotherapy and early drug trials.<br />

<strong>The</strong> new Genetic<br />

Epidemiology Building,<br />

which will open in the<br />

autumn of 2005.<br />

<strong>Research</strong> Highlights<br />

<strong>The</strong> most important event so far in our Genetic<br />

Epidemiology Programme occurred in September with<br />

the launch of the Breakthrough Generations Study. This<br />

exciting new partnership with Breakthrough Breast<br />

Cancer seeks to understand the environmental, lifestyle<br />

and genetic factors that cause breast cancer. Led by<br />

Professor Tony Swerdlow, Chairman of the Section of<br />

Epidemiology, and Professor Alan Ashworth, Director of<br />

the Breakthrough Toby Robins Breast Cancer <strong>Research</strong><br />

Centre, the study will recruit over 100,000 women and<br />

follow them for forty years. It will collect data on their<br />

genetics, their reproductive history, their hormonal<br />

status and their lifestyle, and from such information<br />

we hope to deduce the factors that cause the disease.<br />

Such knowledge is essential if there are ever to be<br />

effective prevention programmes. This study, and others<br />

of a similar nature, will be greatly facilitated by the new<br />

Genetic Epidemiology Building, which will open in the<br />

autumn of 2005, and has been made possible by a<br />

£9.2M grant from the Higher Education Funding<br />

Council for England’s Science <strong>Research</strong> Investment<br />

Fund. As well as providing state of the art<br />

accommodation for the scientists involved, the building<br />

will provide us with the capacity to store the vast<br />

number of samples, and paper questionnaire records,<br />

that will be collected from the participants.<br />

Our understanding of the genetic basis of cancer<br />

advances rapidly. Professor Mike Stratton, with<br />

colleagues in the Cancer Genome Project, showed that<br />

a subset of lung cancer patients carry mutations in the<br />

ErbB2 gene. This encodes a tyrosine kinase and is thus<br />

a highly promising target for therapeutic intervention,<br />

given that we know that mutations in the related<br />

ErbB1 gene confer sensitivity to the drug Iressa.<br />

Professor Nazneen Rahman, team leader in the Section<br />

of Cancer Genetics and Honorary Consultant in Medical<br />

Genetics, studied a very rare condition called Multiple<br />

Variegated Aneupoloidy. Aneuploidy, a feature of many<br />

tumour cells, means that they have the wrong number<br />

of chromosomes, and it has long been argued whether<br />

it is a cause or a consequence of cancer. Children with<br />

the condition have an elevated risk of cancer. She<br />

showed that it results from mutations in the Bub1B<br />

gene, which we knew from studies in yeast is involved<br />

in the process by which the daughter chromosomes are<br />

separated at each cell division. Her data show clearly<br />

that aneuploidy is a cause, it significantly increases the<br />

risk of cancer. Dr Arthur Zelent, a member of the new<br />

joint Section of Haemato-oncology, was part of an<br />

international collaboration that showed that a<br />

transcriptional repressor called Pokemon is a critical<br />

factor in tumour formation. In the absence of this<br />

protein, cells are completely refractory to oncogeneinduced<br />

transformation while its over-expression causes


REVIEW OF <strong>2004</strong><br />

tumours. It is highly expressed in human cancers in a<br />

fashion related to clinical outcome and is thus an<br />

attractive target for therapeutic intervention.<br />

In Molecular Pathology one of our main objectives<br />

is to find ways of telling whether prostate cancer,<br />

diagnosed following a PSA test, is aggressive and<br />

requires immediate clinical intervention, or whether<br />

it is indolent, ie it will grow slowly and the patient can<br />

be spared treatment, needing only careful monitoring.<br />

It was thus of great significance when Colin Cooper, the<br />

Grand Charity of the Freemasons Professor of Molecular<br />

Biology, and his colleagues showed that the E2F-3 gene<br />

is over-expressed in prostate cancer, and that the levels<br />

of expression correlate very well with the<br />

aggressiveness of the tumour. It will now be important<br />

to see if this observation can be developed into a<br />

routine test. Moreover, because we know that the<br />

E2F-3 protein functions in the control of the cell cycle,<br />

we may also have identified a therapeutic target. To<br />

complement this, the hospital has a major clinical<br />

research programme in early prostate cancer called<br />

Active Surveillance, in which suitable patients are<br />

monitored closely rather than treated immediately,<br />

and it seems that the majority of these patients will<br />

completely avoid the need for radical treatments.<br />

This was a year of much progress in the<br />

development and validation of new treatment<br />

modalities. For a considerable number of years<br />

Professor Paul Workman, Director of the Cancer<br />

<strong>Research</strong> UK Centre for Cancer <strong>The</strong>rapeutics, and his<br />

colleagues have been studying inhibitors of the<br />

molecular chaperone HSP90, which is involved in the<br />

proper folding of a number of proteins known to play<br />

key roles in oncogenesis. Together with the team of<br />

Professor Laurence Pearl, Co-Chairman of the Section<br />

of Structural Biology, they have developed novel small<br />

molecule inhibitors of the chaperone, in a highly<br />

Professor Stan Kaye<br />

who heads the new<br />

Drug Development Unit.<br />

<strong>Research</strong> volunteers in the<br />

hyperbaric oxygen chamber<br />

at the Institute of Naval<br />

Medicine at Haslar<br />

productive collaboration with Vernalis Ltd, and it was<br />

a significant step forward when the major<br />

pharmaceutical company Novartis licensed this<br />

technology in order to take it forward into the clinic.<br />

<strong>The</strong> initial stages of the clinical development of a<br />

new anti-cancer drug depend upon Phase I trials, in<br />

which the safety and pharmacokinetic properties of<br />

the molecule are assessed, although with the new<br />

generation of molecularly targeted therapies, efficacy<br />

data may also be gathered at this stage. In order to<br />

significantly increase our capacity for Phase I trials<br />

the <strong>Royal</strong> <strong>Marsden</strong>, with the most generous support<br />

of the Oak Foundation, has constructed a new Drug<br />

Development Unit which will be headed by Professor<br />

Stan Kaye, the Cancer <strong>Research</strong> UK Professor of<br />

Medical Oncology. New treatments can be developed<br />

much more rapidly if their pharmacology, localisation<br />

and molecular targeting can be verified and early<br />

responses assessed sensitively, and new functional<br />

imaging techniques offer the opportunity to do this<br />

efficiently and non-invasively. <strong>The</strong> <strong>Royal</strong> <strong>Marsden</strong> has<br />

installed a new PET-CT facility, and an additional MRI<br />

machine has been purchased.<br />

Once there is evidence that a new drug induces<br />

clinically significant responses, before it can be<br />

marketed and widely prescribed its value must be<br />

rigorously evaluated in large Phase III trials. Ms Judith<br />

Bliss, the Chairman of the Section of Clinical Trials,<br />

co-ordinated a major international trial which showed<br />

that the aromatase inhibitor exemestane is of<br />

significant benefit to post-menopausal women who<br />

have had breast cancer. Last year we reported that<br />

Professor Ian Smith, Head of the Breast Unit, had<br />

led the initial trial of another aromatase inhibitor,<br />

letrozole, now shown to be of great benefit. This new<br />

class of drug, which acts by blocking the synthesis of<br />

the female hormone oestrogen, will markedly change<br />

the clinical management of breast cancer. Professor<br />

David Cunningham, Head of the Gastro-Intestinal<br />

Cancer Unit, was a leader in trials which showed that<br />

Capecitabine, an oral pro-drug of 5-Fluorouracil, and<br />

the monoclonal antibody Cetuximab, are agents that<br />

can be highly effective in colorectal cancer patients.<br />

Large, randomised trials of surgical procedures<br />

are not common but Mr Meirion Thomas, Consultant<br />

Sarcoma Surgeon at the <strong>Royal</strong> <strong>Marsden</strong>, led a trial,<br />

again co-ordinated by Ms Judith Bliss, which showed<br />

clearly that the excision width, ie the amount of tissue<br />

surrounding the tumour that is removed with it, is a<br />

highly influential factor in the survival of patients with<br />

malignant melanoma. Perhaps even more unusual was<br />

a trial led by Professor John Yarnold which explored<br />

the use of hyperbaric, ie high pressure, oxygen in the<br />

treatment of lymphoedema. Swelling of the arms<br />

is a common side-effect in women who have had<br />

surgery and radiotherapy for breast cancer and it can<br />

have a real effect on their quality of life. Sitting in a<br />

hyperbaric chamber, of the sort used to help deepsea<br />

divers recover from the bends, appears to bring<br />

great benefit and further, larger trials are now<br />

being planned.


REVIEW OF <strong>2004</strong><br />

While there have been great successes in the<br />

treatment of cancers in children, most notably with<br />

leukaemia, the therapies can lead to major problems<br />

in later life, and there are tumours, like<br />

neuroblastoma, for which there are no effective drugs.<br />

<strong>The</strong> development of new treatments for paediatric<br />

cancers is thus a high priority, and it is something that<br />

must be pursued in an academic environment as the<br />

number of patients is not sufficient to attract the<br />

attention of pharmaceutical companies. We were thus<br />

delighted when Andy Pearson accepted the Cancer<br />

<strong>Research</strong> UK Chair of Paediatric Oncology. He was<br />

formerly Professor of Paediatric Oncology and Dean<br />

of Postgraduate Studies in the Faculty of Medical<br />

Sciences at the University of Newcastle, and is<br />

Chairman of the United Kingdom Children’s Cancer<br />

Study Group. His mission is to exploit our expertise<br />

in cancer genetics and drug development in order to<br />

identify and validate new, targeted therapies for<br />

childhood cancers, and to lead the paediatric<br />

oncology service in the hospital.<br />

New Developments<br />

As noted above, in the context of the Breakthrough<br />

Generations Study, <strong>The</strong> Institute is currently constructing<br />

a new building on the Sutton Campus that will provide<br />

state of the art accommodation for the Sections of<br />

Clinical Trials and Epidemiology, and also for essential<br />

support functions like Information Technology, the<br />

Registry and Facilities. We have been informed of our<br />

provisional allocation from the next phase of the<br />

Science <strong>Research</strong> Investment Fund, and are likely to<br />

expend these monies, some £11M, on major<br />

renovations of the Old Building at the Chester Beatty<br />

Laboratories in Chelsea and of the Haddow Laboratories<br />

in Sutton, and on the purchase of new equipment.<br />

Better Healthcare<br />

Closer to Home<br />

<strong>The</strong> <strong>Royal</strong> <strong>Marsden</strong> and <strong>The</strong> Institute have been<br />

contributing to consultation on a new model of care<br />

in South West London called ‘Better Healthcare Closer<br />

to Home’. This will involve the creation of a critical<br />

care hospital, co-located with <strong>The</strong> <strong>Royal</strong> <strong>Marsden</strong> and<br />

<strong>The</strong> Institute in Sutton, and ten local care hospitals.<br />

<strong>The</strong> overall aim is to create a service and academic<br />

centre of excellence on the Sutton site, in collaboration<br />

with NHS partners and St George’s Hospital Medical<br />

School, supported by the delivery of more locally based<br />

day care and outpatient facilities for patients. It will<br />

also enable us to make significant investment in our<br />

infrastructure, improving the environment for patients<br />

and staff and for our combined research enterprise.<br />

News of our staff and<br />

their achievements<br />

We were delighted that Professors Colin Cooper<br />

and Stan Kaye were elected to the Fellowship of the<br />

Academy of Medical Sciences. One fifth of our faculty<br />

have now been accorded this honour, an excellent<br />

achievement. Professor Laurence Pearl was elected to<br />

membership of the European Molecular Biology<br />

Organisation, in recognition of his outstanding<br />

contributions to structural biology. A vital part of our<br />

activity is the attraction of the brightest and best young<br />

clinicians and scientists. We were thus particularly<br />

pleased that Drs Tim Crook, who will shortly join the<br />

Breakthrough Centre, and Chris Parker, team leader in<br />

the Section of Radiotherapy and Honorary Consultant<br />

in Clinical Oncology, were awarded prestigious Cancer<br />

<strong>Research</strong> UK Clinician Scientist Fellowships. We were<br />

delighted that Dr Clare Shaw was appointed as the<br />

first Consultant Dietician in the NHS (see her article<br />

on page 58).<br />

Financial Facts and Figures<br />

<strong>The</strong> principal sources of income and the expenditure<br />

of our joint institution are summarised in the Facts<br />

and Figures page (page 12). Full and detailed<br />

statements of the financial accounts of <strong>The</strong> Institute<br />

of Cancer <strong>Research</strong> (August 2003 to July <strong>2004</strong>) and<br />

<strong>The</strong> <strong>Royal</strong> <strong>Marsden</strong> NHS Foundation Trust (April <strong>2004</strong><br />

to March 2005, to be published in September 2005)<br />

are separately recorded in our respective <strong>Annual</strong><br />

<strong>Report</strong>s and Accounts. In the financial year ending on<br />

31 March 2005, the Trust met its key financial objectives<br />

and achieved a balanced budget. In the financial year<br />

ending on 31 July <strong>2004</strong>, <strong>The</strong> Institute achieved a<br />

balanced budget on unrestricted funds after transfers.<br />

Its expenditure on research grew by 10.7% from the<br />

previous year, with increases in research expenditure<br />

across a number of research Sections.<br />

Overall, the combined<br />

annual turnover of<br />

our organisation was<br />

£203.1 million, with<br />

89% of this total being<br />

devoted to research<br />

activities and patient<br />

care services.<br />

Government funding for our joint research activities<br />

contributes 42% of the total resources for research.<br />

Our success rate in competing for research funding<br />

from external sources continues to be outstanding,<br />

at 75% of the value of all applications for peerreviewed<br />

grants to medical charities and government<br />

funding agencies. <strong>The</strong> Institute is particularly indebted<br />

to its major funding partners – Cancer <strong>Research</strong> UK,<br />

Breakthrough Breast Cancer, Leukaemia <strong>Research</strong>,<br />

the Wellcome Trust, the Medical <strong>Research</strong> Council,<br />

Department of Health, and many other medical<br />

research sponsors.<br />

New commercial partners collaborating in drug<br />

development at <strong>The</strong> Institute and supporting clinical<br />

trials at the <strong>Royal</strong> <strong>Marsden</strong> include: AstraZeneca,<br />

Novartis, Vernalis Ltd, Astex Technology Ltd, Pfizer,<br />

Antisoma and BTG.<br />

Many organisations also contribute support by<br />

providing funds for studentships at <strong>The</strong> Institute and<br />

clinical fellowships at the hospital. <strong>The</strong> <strong>Royal</strong> <strong>Marsden</strong><br />

and <strong>The</strong> Institute are grateful to all the numerous<br />

organisations and supporters who have made<br />

investments in our research activities.<br />

Fundraising<br />

<strong>The</strong> <strong>Royal</strong> <strong>Marsden</strong> publicly launched its £30 million<br />

appeal to finance a number of major projects to provide<br />

a range of new facilities and leading edge equipment<br />

which will enhance the hospital’s research capacity as<br />

well as provide improved treatments for patients.<br />

Generous gifts from an anonymous charitable<br />

foundation, the Oak Foundation, the Garfield Weston<br />

Foundation, John and Catherine Armitage, the PF<br />

Charitable Trust, the Wolfson Foundation, the Arbib<br />

Foundation, Martin Myers and a number of other trusts<br />

and private individuals, brought the sum pledged to £24<br />

million by the end of the year. <strong>The</strong> loyal support of the<br />

hospital’s staff and patients, their families and friends<br />

and the general public contributed some £2 million to<br />

that total. Our thanks go to all the dedicated people<br />

who have done so much to bring the appeal’s final<br />

target in sight so speedily.<br />

<strong>The</strong> Institute continues to receive significant support<br />

from charitable trusts, companies and an increasing<br />

number of individuals. Our Everyman Male Cancer


REVIEW OF <strong>2004</strong><br />

Campaign attracted unprecedented support during <strong>2004</strong><br />

which included partnerships with Topman, <strong>The</strong> Football<br />

Association, <strong>The</strong> Professional Footballers’ Association and<br />

Gillette UK, among many others. We extend our most<br />

grateful thanks to all those who have contributed to<br />

our continuing success, including <strong>The</strong> Grand Charity of<br />

Freemasons, the Garfield Weston Foundation, ICAP plc<br />

and the many individuals, trusts and companies who<br />

Interactive Education Unit<br />

Kathryn Allen PhD, Director<br />

<strong>The</strong> Interactive Education Unit (IEU) was established at<br />

<strong>The</strong> Institute in 1999 with the remit to develop Weband<br />

CD ROM-based educational resources<br />

(www.ieu.icr.ac.uk). <strong>The</strong> overarching aim of the<br />

IEU is to promote and disseminate the educational,<br />

research and clinical activities of <strong>The</strong> Institute in order<br />

to improve the treatment, care and quality of life of<br />

people with cancer. <strong>The</strong> Unit’s work was highlighted<br />

as an area of good practice in the educational audit of<br />

<strong>The</strong> Institute in early <strong>2004</strong>, undertaken by the Quality<br />

Assurance Agency. <strong>The</strong> IEU website was a Platinum<br />

award winner in the <strong>2004</strong> MarCom creative awards,<br />

a leading international marketing and<br />

communications competition.<br />

IEU projects are developed in collaboration with<br />

leading scientists and clinicians at both <strong>The</strong> Institute<br />

and the <strong>Royal</strong> <strong>Marsden</strong>. <strong>The</strong> Unit has three key markets:<br />

scientists and students, healthcare professionals and<br />

patients and the public.<br />

Scientists and students –<br />

Perspectives in Oncology, the cancer science website<br />

– this website (see Figure 1) was launched in June<br />

<strong>2004</strong> to provide students at <strong>The</strong> Institute with a<br />

thorough and connected grounding in the field of<br />

cancer science. <strong>The</strong> site emphasises how discoveries<br />

in scientific research translate into clinical care and<br />

highlights how the fields of physics, biology,<br />

chemistry and medicine all contribute to<br />

understanding, managing and treating cancer.<br />

<strong>The</strong> site was launched initially with five modules,<br />

covering causes and prevention of cancer, common<br />

cancers, therapies, genetics of cancer and<br />

bioinformatics. Five further modules are scheduled<br />

for development in 2005–06. Perspectives<br />

in Oncology was a Gold Finalist in the <strong>2004</strong><br />

MarCom creative awards competition.<br />

Healthcare professionals –<br />

supporting evidence-based practice<br />

Examples of projects in this category are:<br />

A Breath of Fresh Air CD ROM – this interactive<br />

guide to managing breathlessness in patients with<br />

advanced lung cancer is based on research work<br />

pioneered at <strong>The</strong> Institute and the <strong>Royal</strong> <strong>Marsden</strong>.<br />

Over 14,000 copies of A Breath of Fresh Air have<br />

been distributed worldwide since its launch in 2001.<br />

<strong>The</strong> programme is provided free to healthcare<br />

professionals thanks to generous sponsorship from<br />

the Diana, Princess of Wales Memorial Fund Project,<br />

Macmillan Cancer Relief and Marks & Spencer, and<br />

can be ordered by calling 0800 9177263. <strong>The</strong><br />

programme is currently being updated.<br />

RT Plan, the conformal radiotherapy website – this<br />

website, currently in development, will help to<br />

educate oncology clinicians and trainees in 3D<br />

conformal radiotherapy planning in patients with<br />

localised prostate cancer.<br />

Pain Management CD ROM – currently in<br />

development, this interactive guide to managing<br />

pain in cancer will provide a comprehensive<br />

overview of the subject, featuring case histories and<br />

management tools to use with patients.<br />

Patients and the public – cancer education<br />

An example of a project in this category is:<br />

Relax and Breathe – this resource, developed in<br />

collaboration with Macmillan Cancer Relief, is<br />

available in both CD and audiotape format. It<br />

features practical guidance and exercises on<br />

relaxation. <strong>The</strong> resource is designed to help people<br />

with lung cancer cope with their breathlessness, but<br />

can also be used by healthcare professionals<br />

wanting to learn and practise relaxation. Over 7,000<br />

copies of the CD, 2,000 of the audiotape and 1,500<br />

of the healthcare professionals resource pack have<br />

been distributed so far. Relax and Breathe is<br />

available free thanks to sponsorship from Macmillan<br />

Cancer Relief, and can be ordered by calling the<br />

Macmillan Resources line on 01344 350 310,<br />

Technology Transfer<br />

<strong>Report</strong> <strong>2004</strong><br />

<strong>The</strong> Institute and the <strong>Royal</strong> <strong>Marsden</strong> work with commercial<br />

partners so that research findings can be developed and<br />

distributed for the benefit of patients worldwide.<br />

<strong>The</strong> Director of Enterprise outlines the highlights of this<br />

technology transfer activity during <strong>2004</strong>.<br />

TECHNOLOGY TRANSFER<br />

Susan Bright<br />

PhD<br />

Dr Susan Bright is<br />

Director of Enterprise<br />

of <strong>The</strong> Institute of<br />

Cancer <strong>Research</strong><br />

<strong>The</strong> Enterprise Unit at the <strong>The</strong> Institute, working<br />

together with the <strong>Royal</strong> <strong>Marsden</strong>, has again had a<br />

very active and successful year.<br />

<strong>The</strong> objective of the Enterprise Unit is to facilitate<br />

the transfer of research outputs to commercial<br />

organisations that can provide development resources.<br />

Inventions are thereby disseminated to as wide a<br />

patient base as possible.<br />

Our technology transfer<br />

effort focuses primarily on<br />

ensuring that the route of<br />

development chosen is<br />

capable of delivering<br />

maximum patient benefit.<br />

Return of revenue to <strong>The</strong> Institute and the <strong>Royal</strong><br />

<strong>Marsden</strong> is a welcome additional result of the work<br />

of the Enterprise Unit. <strong>The</strong> Enterprise Unit continues to<br />

work in partnership with Cancer <strong>Research</strong> Technology<br />

Ltd (CRT) who take the lead in the commercial<br />

exploitation of Cancer <strong>Research</strong> UK funded work.<br />

<strong>The</strong> Unit also works closely with British Technology<br />

Group (BTG), <strong>The</strong> Wellcome Trust and other technology<br />

transfer organisations as appropriate to specific projects.<br />

Astex Technology Ltd<br />

(PKB Collaboration)<br />

In 2003 <strong>The</strong> Institute began a collaboration with<br />

the fragment-based, drug discovery company Astex<br />

Technology Ltd on the development of novel<br />

inhibitors of the enzyme protein kinase B (PKB).<br />

It is anticipated that these inhibitors will be useful<br />

anticancer drugs. Professors David Barford, Paul<br />

Workman and Dr Michelle Garrett are project leaders<br />

at <strong>The</strong> Institute for this collaboration. Good progress<br />

continues to be made and the partnership is clearly<br />

illustrating the synergy that can be achieved when two<br />

strong research teams work together. Two series of<br />

novel potent PKB inhibitors have been identified.<br />

17


PETRRA Ltd<br />

<strong>The</strong> Institute continues its active involvement in the<br />

spin-out company PETRRA, which was founded to<br />

develop the novel positron emission tomography (PET)<br />

camera invented by <strong>The</strong> Institute, the <strong>Royal</strong> <strong>Marsden</strong><br />

and the Rutherford Appleton Laboratory, based on the<br />

research of Professor Bob Ott. <strong>The</strong> first clinical trial of<br />

the camera began at the <strong>Royal</strong> <strong>Marsden</strong> in 2002 and<br />

was successfully completed in <strong>2004</strong>. <strong>The</strong> camera<br />

demonstrated its ability to produce high-quality images<br />

efficiently and cheaply. PETRRA has secured additional<br />

funding from a seed investment fund. A new CEO will<br />

be appointed and PETRRA will actively seek a<br />

commercial partner in 2005.<br />

Domainex Ltd<br />

In 2002 <strong>The</strong> Institute played a key role in establishing<br />

the new spin-out company Domainex together with its<br />

partners, University College and Birkbeck College.<br />

Domainex secured investment from the Bloomsbury<br />

Bioseed Fund and Dr Keith Powell was appointed CEO.<br />

Institute founder scientists are Professor Laurence Pearl<br />

and Dr Chris Prodromou. Domainex was established to<br />

exploit a novel technology developed by the founders<br />

that enables rapid analysis of the structure and function<br />

of complex proteins. <strong>The</strong> technology can be applied to a<br />

wide range of oncology targets. In <strong>2004</strong> Domainex<br />

signed its first commercial contract with Inpharmatica<br />

and obtained additional funding from the DTI. <strong>The</strong><br />

company now has funds to last until 2006 and further<br />

commercial contracts are actively being pursued.<br />

Chroma <strong>The</strong>rapeutics Ltd<br />

<strong>The</strong> Institute continues its active involvement in<br />

the spin-out company Chroma, which was founded to<br />

develop novel anticancer drugs based on enzymes<br />

involved in the remodelling of chromatin. Chroma is<br />

based on work at <strong>The</strong> Institute and the University of<br />

Cambridge. Professor Paul Workman is <strong>The</strong> Institute's<br />

founder scientist. In <strong>2004</strong> Chroma’s first product<br />

entered Phase I clinical trials and significant progress<br />

was made in a number of key projects. In addition<br />

the company raised an additional £15 million of<br />

venture capital funding ensuring a good foundation<br />

for the future.<br />

PIramed Ltd<br />

<strong>The</strong> company PIramed Ltd was founded in 2003 based<br />

on research arising from the Ludwig Institute of Cancer<br />

<strong>Research</strong>, Cancer <strong>Research</strong> UK and <strong>The</strong> Institute.<br />

Professor Paul Workman is <strong>The</strong> Institute’s founder<br />

scientist. PIramed has funding from JP Morgan Partners<br />

and Merlin Biosciences and is developing a number of<br />

drug products principally focused on inhibitors of the<br />

PI3 kinase superfamily. Good progress was made in<br />

<strong>2004</strong> on the lead project and a clinical candidate has<br />

been selected.<br />

Vernalis Ltd<br />

(HSP90 collaboration)<br />

In 2002 <strong>The</strong> Institute began a collaboration with the<br />

Cambridge based biotechnology company RiboTargets<br />

(now Vernalis Ltd) to develop inhibitors of the molecular<br />

chaperone Hsp90. Hsp90 plays an important role in<br />

directing the function of many key intracellular<br />

‘oncogenic’ proteins. Inhibitors of Hsp90 will affect the<br />

function of these proteins and this will result in an<br />

anticancer effect. <strong>The</strong> Hsp90 project combined the<br />

resources and skills of both Vernalis and <strong>The</strong> Institute; at<br />

<strong>The</strong> Institute the lead scientists on this programme were<br />

Professors Laurence Pearl and Paul Workman. <strong>The</strong><br />

collaboration ended its first phase in <strong>2004</strong> having<br />

successfully developed several novel, potent Hsp90<br />

inhibitors. Vernalis has now secured a licensing<br />

agreement with Novartis who will take these<br />

compounds into the clinic.

BRAF Collaboration with<br />

<strong>The</strong> Wellcome Trust<br />

In 2002 <strong>The</strong> Institute began a collaboration with <strong>The</strong><br />

Wellcome Trust and Cancer <strong>Research</strong> UK to develop<br />

novel drugs to inhibit the enzyme BRAF. <strong>The</strong><br />

identification of BRAF as a cancer target came out<br />

of <strong>The</strong> Institute's involvement with the Wellcome<br />

funded Cancer Genome Project. <strong>The</strong> joint venture is<br />

managed by Institute scientists, the Enterprise Unit,<br />

CRT and <strong>The</strong> Wellcome Trust. In addition the company<br />

Astex Technology Ltd joined the collaboration in <strong>2004</strong>.<br />

<strong>The</strong> project manager is Dr Richard Marais from <strong>The</strong><br />

Institute and the Wellcome Trust is leading the<br />

commercialisation effort. <strong>The</strong> collaboration has identified<br />

two distinct chemical series of promising novel BRAF<br />

inhibitors. A partnership with a pharmaceutical company<br />

is the objective for 2005.<br />

Quinazolines<br />

(BTG collaboration)<br />

Professor Ann Jackman has worked for a number of<br />

years on novel quinazoline anti-cancer drugs. Her first<br />

success in this area was the compound Tomudex which<br />

is now on the market and earning royalties. Three other<br />

quinazoline drugs with different mechanisms of action<br />

are in development, all in partnership with BTG. One of<br />

these drugs, the compound BGC 9331, is successfully<br />

going through a Phase II clinical trial.<br />

MRI Technology<br />

Professor Martin Leach’s team has developed a number<br />

of novel tools to help in the use and analysis of<br />

Magnetic Resonance Imaging. Several patents have<br />

been filed and there are also a number of items of<br />

proprietary software. <strong>The</strong> Enterprise Unit is actively<br />

seeking industrial partners for these technologies.<br />

Patents<br />

In total 15 new patents were filed in <strong>2004</strong> directly by<br />

<strong>The</strong> Institute or in collaboration with other institutions.<br />

One of the patents filed, in collaboration with the<br />

German Cancer <strong>Research</strong> Center (DKFZ), was for a<br />

method of intensity-modulating a beam of radiation<br />

from a radiation source. <strong>The</strong> Variable Aperture<br />

Collimator (Figure 1) can be used instead of a multileaf<br />

collimator and also with intensity-modulated<br />

radiotherapy.<br />

Industrial Collaborations<br />

CANCER BIOLOGY<br />

Dying To Survive:<br />

how can tumour cells escape death<br />

Identification of a novel mode of caspase regulation and<br />

a better understanding of the molecular mechanisms of<br />

programmed cell death are providing greater insights into<br />

how tumour cells bypass apoptosis and survive.<br />

Pascal Meier<br />

PhD<br />

Dr Pascal Meier is Team<br />

Cancer in <strong>The</strong> Breakthrough<br />

Toby Robins Breast Cancer<br />

<strong>Research</strong> Centre at <strong>The</strong><br />

Institute of Cancer<br />

<strong>Research</strong><br />

All cells are mortal<br />

In multicellular organisms fatal cancers occur when<br />

mutated cells proliferate and survive inappropriately.<br />

<strong>The</strong> human body is composed of approximately 10 14<br />

cells, which fall into a multitude of diverse cell types.<br />

Given the vast number of cells in our body it is<br />

surprising how little generally goes wrong. One of the<br />

reasons is the body’s astounding ability to correct errors.<br />

All cells have built-in auto-destruct<br />

mechanisms<br />

It is now clear that each cell carries within it a built-in<br />

auto-destruct mechanism, which limits the survival and<br />

expansion of a cell if it becomes potentially harmful or<br />

malignant. Thus, cancer cells that spontaneously arise<br />

out of these 10 14 cells are normally eliminated because<br />

the cell activates its intrinsic suicide programme. This<br />

self-destruct mechanism – called apoptosis – is a key<br />

defence strategy against the emergence of cancer.<br />

Apoptosis and the pathogenesis of disease<br />

With good reason, apoptosis is currently one of the<br />

hottest areas of modern biology. A closer look at the<br />

basis of the pathogenesis of most human diseases<br />

almost always reveals a defect in some component of<br />

apoptosis, which either contributes to the disease or<br />

accounts for it.<br />

Diseases characterised<br />

by the failure of cells to<br />

undergo apoptotic cell<br />

death include cancer,<br />

autoimmune disease<br />

and viral infection. In<br />

contrast, too much<br />

cell death can lead<br />

to diseases such as<br />

neurodegenerative<br />

disorders, AIDS or<br />

osteoporosis.<br />

Apoptosis and organ development<br />

While apoptosis is clearly involved in the pathogenesis<br />

of a variety of human diseases, it is nevertheless also an<br />

essential building block during the normal development<br />

of a multicellular organism. In general, during an<br />

organism’s development there is an initial over-generation<br />

of excess cells from which a final tissue or organ is<br />

ultimately formed. However, during the later stages of<br />

development, dispensable and supernumerary cells are<br />

subsequently eliminated by apoptosis so that a balance<br />

can be achieved of the relative number of cells of<br />

different types, thereby allowing proper organ function.<br />

Apoptosis and homeostasis<br />

Thus, during early development, apoptosis is needed<br />

to sculpt structures such as fingers and toes. Later on<br />

in life, apoptosis is also instrumental to ensure that<br />

organ size remains constant – a process called tissue<br />

homeostasis. For example, during each menstrual cycle<br />

the epithelium of the normal human breast undergoes<br />

a phase of cell expansion. However, later on, a phase of<br />

cell removal follows which reduces the breast back to its<br />

original size. Similarly, during pregnancy and lactation<br />

high levels of cell proliferation and differentiation occur<br />

in the breast, leading to a massive expansion of the<br />

mammary gland. But, after lactation has finished, the


differentiated lactating lobules are no longer required<br />

and are then removed by apoptosis, returning the organ<br />

to its mature resting state. Thus, during adult life, as<br />

during development, numerous structures are formed<br />

that are later removed by apoptosis.<br />

Repair by self-destruction<br />

Substantial evidence indicates that the very same<br />

genetic mutations that trigger uncontrolled cell<br />

expansion, and hence might give rise to cancer, at<br />

the same time also trigger spontaneous activation of<br />

cell death. <strong>The</strong> finding that the molecular lesions that<br />

generate uncontrolled cell expansion also coordinately<br />

trigger cell death indicates that under normal<br />

circumstances apoptosis acts as a fail-safe strategy<br />

to hinder the expansion of potentially harmful cells. In<br />

this respect, apoptosis acts as part of a quality-control<br />

and repair mechanism that eliminates unwanted cells.<br />

Consequently, cancer can only ever emerge if apoptosis<br />

has been suppressed.<br />

Most types of cancer<br />

cells show an acquired<br />

resistance toward<br />

apoptosis.<br />

Cancer therapies and<br />

apoptosis – reason for concern<br />

<strong>The</strong> goal of all current cancer therapies, which include<br />

radiation, chemotherapy, immunotherapy and gene<br />

therapy, is the obliteration of the cancer cell. However,<br />

it is now clear that the effects of radiotherapy and<br />

chemotherapeutic agents result in a response by which<br />

the treated cancer cell kills itself by activating its own<br />

in-built self-destruct programme. Thus, the success of<br />

current therapeutic intervention schemes heavily relies<br />

on the ability of the cancer cell to activate its own<br />

apoptosis programme. This exposes a significant<br />

problem with current therapeutic strategies.<br />

Because cancer cells can only ever emerge if the<br />

apoptosis programme is either blocked or dampened,<br />

the very same mutations that permit tumour formation,<br />

by suppressing apoptosis, will also reduce treatment<br />

sensitivity and will therefore contribute to treatment<br />

failure. Not surprisingly, therefore, such therapeutic<br />

strategies often fail to selectively eradicate neoplastic cells.<br />

Understanding the tools of<br />

the ‘Grim Reaper’<br />

To try to resolve how cancer cells bypass apoptosis,<br />

the Apoptosis Team within <strong>The</strong> Breakthrough Toby<br />

Robins Breast Cancer <strong>Research</strong> Centre is studying the<br />

machinery that executes apoptosis and the molecular<br />

mechanisms that control this potentially catastrophic<br />

process. Our work concentrates on the engines of the<br />

apoptotic execution programme. <strong>The</strong> destructive<br />

components of this cell-death machinery consist of a<br />

group of highly specialised proteases (enzymes that<br />

break down proteins) called caspases.<br />

Caspases form the molecular chainsaws of the<br />

self-destruct programme which, when activated, cut<br />

the cell to pieces. Activation of caspases is a key event<br />

in apoptotic signalling and is required to execute cell<br />

death. Caspases are present in every cell at all times,<br />

but remain dormant. However, upon exposure to<br />

DNA damage, chemotherapeutic compounds or<br />

developmental signals, caspases become rapidly<br />

activated. Once active, caspases cleave and destroy a<br />

multitude of polypeptides inside the cell that are vital<br />

for cellular function, shape and integrity. Cells are<br />

destroyed and removed within minutes of caspase<br />

activation – an event which is, self-evidently, potentially<br />

catastrophic and must be tightly regulated.<br />

<strong>The</strong> last line of defence – IAPs<br />

Certain members of the evolutionarily conserved<br />

inhibitors of apoptosis (IAP) protein family have been<br />

found to function as guardians of the apoptotic<br />

machinery. IAPs were originally identified in viruses but<br />

are also present in animals as diverse as insects and<br />

humans. Most importantly, IAPs suppress apoptosis<br />

extremely efficiently.<br />

Recent studies show that several human IAPs are<br />

strongly upregulated in many cancers. For example,<br />

deregulated levels of the mammalian IAP XIAP are<br />

<strong>The</strong> observation that IAPs suppress apoptosis very<br />

effectively and are present in cancer cells strongly<br />

suggests that IAP-mediated inhibition of apoptosis<br />

contributes to tumour pathogenesis, disease progression<br />

and/or resistance to drug treatment.<br />

Mark Ditzel and Rebecca Wilson have investigated<br />

how IAPs suppress cell death. <strong>The</strong>y made the striking<br />

observation that IAPs inhibit deadly caspases by fusing<br />

another protein, called ubiquitin, onto caspases (Figure<br />

1). <strong>The</strong> ubiquitin label inactivates the caspases and the<br />

cell survives. <strong>The</strong> fate of proteins that are modified with<br />

a ubiquitin label can vary substantially, with some<br />

polyubiquitylated proteins being disassembled and<br />

destroyed by the cell’s demolition centre, the<br />

proteasome, while others end up in different subcellular<br />

compartments, and yet others are inactivated.<br />

IAPs belong to a specialised group of proteins, called<br />

E3 ubiquitin protein ligases, which transfer ubiquitin<br />

protein labels onto caspases thereby blocking cell death.<br />

Survival through mutual<br />

annihilation<br />

While IAPs label caspases with ubiquitin, caspases are<br />

not the only proteins that are modified with ubiquitin.<br />

Mark Ditzel and Rebecca Wilson also found that, in the<br />

process, IAPs themselves become coated with ubiquitin.<br />

Attaching ubiquitin to IAPs has dire consequences for<br />

the affected IAP itself, since this modification targets it<br />

for proteasomal demolition. Because IAPs represent the<br />

last line of defence against caspase-mediated damage it<br />

appears to be somewhat counterintuitive that the cell<br />

gets rid of its own guardian. So, why should it be<br />

beneficial to a cell to destroy its own protector<br />

<strong>The</strong> answer to this is that ubiquitin-mediated<br />

instability of IAPs reflects the natural occupational<br />

hazard of being a ubiquitin-handling E3 protein ligase.<br />

<strong>The</strong> intrinsic instability of IAPs and their anti-apoptotic<br />

activity is intimately intertwined. Genetic and molecular<br />

studies indicate that IAP destruction is in fact essential<br />

for their ability to block apoptosis. Only IAPs that are<br />

unstable and are destroyed are capable of controlling<br />

caspases. This raises the intriguing possibility that IAPs<br />

suppress apoptosis by actively searching out and<br />

destroying activated caspases. In this respect, IAPs and<br />

caspases would be coordinately destroyed in an<br />

altruistic sacrifice.<br />

This discovery has major implications for the<br />

generation of novel therapeutic small molecule<br />

inhibitors designed to block the E3 ubiquitin protein<br />

ligase activity of IAPs.<br />

In the presence of such inhibitors of IAPs, caspases<br />

would no longer be coated with ubiquitin and hence<br />

would remain active and destroy the cancer cell.<br />

Since only cancer cells, but not normal cells,<br />

constantly drive the activation of caspases, such E3-<br />

inhibition is predicted to selectively kill tumour cells.


CANCER BIOLOGY<br />

SMAC ’em dead<br />

It is now clear that apoptosis is implemented by<br />

caspases. To date 11 caspases have been identified in<br />

humans. While XIAP suppresses only three of these, it is<br />

currently unclear how the remaining set of caspases is<br />

controlled.<br />

How caspases are kept quiet<br />

Tencho Tenev and Anna Zachariou have studied how<br />

caspases are kept in abeyance. <strong>The</strong>y made the discovery<br />

that certain caspases carry an evolutionarily conserved<br />

motif, which is designed to attract and bind to IAPs,<br />

hence the name IAP-binding motif (IBM). Normally, this<br />

IBM is buried deep within a dormant, non-active caspase.<br />

However, when the caspase is activated, this motif is<br />

exposed and acts like a magnet for IAPs. Thus, even when<br />

caspases are activated this will not necessarily end in cell<br />

death, because IAPs can home in on active caspases and<br />

smother their destructive potential. <strong>The</strong> most exciting<br />

aspect of this discovery is that only a tiny motif, in fact,<br />

one single amino acid residue of the caspase, is crucially<br />

involved in anchoring it to IAPs. Mutation of this one<br />

residue completely abrogates the interaction between<br />

IAPs and caspases. Consequently, activated caspases<br />

become invisible for IAPs and therefore are unrestrained<br />

and free to cause mayhem.<br />

<strong>The</strong> IAP: caspase complex – a new<br />

pharmaceutical target<br />

<strong>The</strong> fact that such a tiny motif is important for the<br />

caspase:IAP association makes it an exciting<br />

pharmaceutical target. Indeed, preliminary studies using<br />

small molecule chemotherapeutic inhibitors that mimic<br />

this single amino acid residue have already given rise to<br />

very exciting preliminary results. Numerous cancer cell<br />

lines appear to be exquisitely sensitive to such agents.<br />

Cancer cells that have been treated with such IBM<br />

mimetics appear to keel over and die owing to<br />

spontaneous and unrestrained activation of caspases.<br />

<strong>The</strong> agents break up the IAP:caspase complex thereby<br />

liberating caspases from IAP-mediated inhibition.<br />

Another regulator of IAPs is a protein called SMAC<br />

which activates caspases by directly inhibiting IAPs.<br />

SMAC mimetics are being developed as anticancer<br />

agents acting through promoting apoptosis.<br />

SMAC mimetics seem<br />

not to harm normal<br />

cells, yet selectively<br />

destroy cancer cells.<br />

This selectivity strongly<br />

indicates that cancer<br />

cells are particularly<br />

addicted to IAPs for<br />

their survival.<br />

Breaching the barricade<br />

This SMAC strategy to kill cancer cells is not a novel<br />

man-made creation but actually is a strategy that nature<br />

has evolved to kill cells during the normal sculpting of<br />

the human body. Normal cells that are destined to die<br />

overcome the IAP-mediated roadblock on caspases. A<br />

specialised group of naturally occurring killer proteins<br />

(IAP-antagonists) trigger cell death by directly blocking<br />

the access of IAPs to caspases. <strong>The</strong> sole function of<br />

these assassin proteins is to bind and antagonise IAPs<br />

thereby displacing and liberating caspases (see Figure<br />

1). Once displaced and relieved of IAP-mediated<br />

inhibition, caspases effect apoptosis.<br />

In the fruit fly Drosophila melanogaster, the world’s<br />

best-known model organism, the activity of IAPantagonists<br />

– which carry intriguing names such as<br />

Reaper, Grim, Sickle, Hid and Jafrac2, is essential for<br />

apoptosis during development. Cells that lack Reaper,<br />

Grim and Hid completely fail to activate the apoptosis<br />

programme – just like cancer cells.<br />

Prospects for the future<br />

Small molecule inhibitors already exist to block IAPs.<br />

Future studies will undoubtedly determine whether such<br />

SMAC compounds can be turned into efficacious small<br />

molecules that enhance the apoptotic mechanism, either<br />

alone or in combination with conventional<br />

chemotherapeutic agents.<br />

A revolution in cancer drug<br />

discovery and treatment<br />

<strong>The</strong> treatment of cancer patients is undergoing a<br />

major revolution away from the use of conventional<br />

chemotherapy, which can indiscriminately kill all<br />

growing cells in the body, towards novel anticancer<br />

agents that specifically target the molecular<br />

abnormalities of the cancer cell itself. This has been<br />

made possible by the implementation of strategies that<br />

investigate the changes that occur in the genetic<br />

information (the DNA) of a cancer cell.<br />

An example of this is the Cancer Genome Project,<br />

which aims to identify most of the genetic changes that<br />

occur in the majority of common cancers. <strong>The</strong> role of the<br />

Cell Cycle Control Team in the Cancer <strong>Research</strong> UK<br />

Centre for Cancer <strong>The</strong>rapeutics is to understand how<br />

G1 –<br />

Cell growth<br />

S – Replication<br />

of genetic<br />

information (DNA)<br />

these genetic changes cause misregulation of the cycle<br />

of cell growth and division, a process known as cell<br />

proliferation (Figure 1), and how we can exploit these<br />

abnormalities of the cancer cell to develop new,<br />

targeted anticancer treatments.<br />

Cell proliferation and cancer<br />

<strong>The</strong> life of a cell in the human body is a complicated<br />

process, often subject to external messages from<br />

surrounding tissues. <strong>The</strong>se messages can tell the cell to<br />

proliferate, through cell growth and division – an event<br />

that can occur when the body needs to replace cells<br />

that have been lost. Once sufficient cells have been<br />

produced, the signal may be withdrawn or a second<br />

signal may be sent telling the cells to stop proliferation.<br />

<strong>The</strong> genetic changes in the DNA of our cells that cause<br />

cancer often affect how a cell will respond to these<br />

signals. <strong>The</strong>se changes in our DNA can be translated<br />

into alterations in the properties or amounts of proteins,<br />

which are the building blocks of our cells.<br />

A change in just one<br />

protein in a cell can<br />

upset its normal<br />

behaviour so that it will<br />

grow and divide into<br />

two cells – even when<br />

it is receiving messages<br />

to stop.<br />

PKB – an important target<br />

for cancer treatment<br />

PKB and cyclin D1<br />

<strong>The</strong> protein PKB (also known as AKT) is part of a<br />

signalling pathway in the cell that promotes both cell<br />

proliferation and survival. This pathway receives signals<br />

from the external environment via a receptor at the cell<br />

surface, which then relays the signal to a protein<br />

complex known as PI3 kinase. PI3 kinase then produces

of cell<br />

a chemical, PIP3, that binds to and promotes activation<br />

of PKB. Once active, PKB sends signals throughout the<br />

cell via interactions with other proteins to promote both<br />

proliferation and survival (Figure 2).<br />

A key downstream target of PKB is a protein known<br />

as cyclin D1, which is an important regulator of cell<br />

proliferation and currently is under investigation in our<br />

laboratory. PKB acts on proliferation by regulating the<br />

amount of cyclin D1 in the cell (Figure 2). When PKB<br />

is actively sending signals throughout the cell, the level<br />

of cyclin D1 will increase, leading to uncontrolled cell<br />

proliferation, as in cancer. When PKB is switched off,<br />

the level of cyclin D1 in the cell will decrease and cell<br />

proliferation will cease.<br />

<strong>The</strong> PI3 kinase/PKB<br />

pathway is a major<br />

controller of cell<br />

proliferation and<br />

survival and it can<br />

become misregulated<br />

in cancer.<br />

Overexpression of receptors that<br />

relay signals in cells<br />

In particular, the receptors that relay signals to the PI3<br />

kinase/PKB pathway (see Figure 2) are overexpressed<br />

in lung and breast cancer, whilst genetic alterations<br />

that cause misregulation of PI3 kinase itself and the<br />

chemical messenger it produces have been discovered<br />

in colon, breast, prostate and ovarian cancer. PKB is<br />

also overexpressed in a number of tumour types.<br />

Overexpression of cyclin D1 is associated with a variety<br />

of cancer types and contributes to the development of<br />

cancer. For example, overexpression of cyclin D1 has<br />

been associated with the development of breast cancer.<br />

<strong>The</strong>se discoveries have led us to initiate a major<br />

programme to discover and develop inhibitors of PKB<br />

for the treatment of cancer.<br />

Inhibition of PKB may<br />

have therapeutic value<br />

in those tumours that<br />

exhibit abnormalities of<br />

the PI3 kinase pathway<br />

or overexpression of<br />

cyclin D1 protein.<br />

Drug discovery and<br />

development – a<br />

multidisciplinary programme<br />

Drug discovery and development require input and<br />

expertise from a number of different disciplines,<br />

including basic research, high throughput screening,<br />

medicinal chemistry, all the way through to the planning<br />

and implementation of clinical trials. <strong>The</strong> PKB<br />

programme reflects this multidisciplinary approach,<br />

involving a number of teams from the Cancer <strong>Research</strong><br />

UK Centre for Cancer <strong>The</strong>rapeutics and the Section of<br />

25


Structural Biology at <strong>The</strong> Institute, along with clinicians<br />

from the <strong>Royal</strong> <strong>Marsden</strong>, and a collaboration with the<br />

biotechnology company, Astex Technology Ltd.<br />

In the Cancer <strong>Research</strong> UK Centre for Cancer<br />

<strong>The</strong>rapeutics, the Analytical Technology and Screening<br />

Team have carried out a high throughput drug screen<br />

for inhibitors of the PKB protein using a library of<br />

compounds. <strong>The</strong>se can then be modified by medicinal<br />

chemists in the Centre to generate more potent and<br />

specific inhibitors of PKB – a process known as lead<br />

optimisation.<br />

Understanding the structure<br />

of PKB provides novel<br />

avenues for drug design<br />

A major scientific breakthrough on the PKB project<br />

came from Professor David Barford of the Section of<br />

Structural Biology when his team solved the 3D<br />

structure of the PKB protein (Figure 3).<br />

This structural knowledge of PKB has aided in<br />

our design of potent and selective inhibitors of PKB.<br />

It has also allowed us, in collaboration with Astex<br />

Technology Ltd, to pursue an alternative strategy for<br />

the identification of PKB inhibitors, which uses<br />

structure-based screening to identify drug fragments<br />

that can then be optimised as lead compounds for<br />

further chemical diversification.<br />

Molecular pharmacology –<br />

an important part of the<br />

drug development process<br />

Evaluating these potential new inhibitors of PKB is the<br />

responsibility of the Cell Cycle Control Team. <strong>The</strong> key<br />

objective here is to determine if the inhibitory<br />

compounds are acting on PKB in the cancer cell. In<br />

order to do this we treat cancer cells with the<br />

compounds and then monitor PKB activity by looking at<br />

the ability of PKB to signal to other proteins to promote<br />

proliferation and survival.<br />

Furthermore, given that we know PKB regulates the<br />

level of the cell cycle protein cyclin D1 in the cell, we<br />

also investigate whether the level of cyclin D1 has<br />

decreased in the presence of the potential PKB inhibitor.<br />

<strong>The</strong> development of these types of read-outs in cancer<br />

cells is extremely important and a key objective is their<br />

eventual use in clinical trials with patients so that we<br />

can assess whether we are inhibiting the target, PKB, in<br />

the patient.<br />

Along with these studies in molecular pharmacology,<br />

teams within the Centre with expertise in<br />

pharmacokinetics and tumour biology then evaluate<br />

these new compounds in laboratory assays. All this<br />

information is then brought together and reviewed for<br />

each compound so that a decision can be made about<br />

whether further optimisation is required.<br />

activated PKB. (Courtesy<br />

Clinical input is vital for<br />

the drug discovery and<br />

development process<br />

Phase I clinical trials<br />

Once optimisation is complete the next stage is to<br />

undertake a Phase I clinical trial with the PKB inhibitor.<br />

This is carried out in the Phase I clinical trials unit at the<br />

<strong>Royal</strong> <strong>Marsden</strong>.<br />

Because the PKB inhibitor is a specific molecularly<br />

targeted agent, it will be important to determine<br />

whether we have inhibited PKB in the tumour of the<br />

patient. Accordingly, an important objective for the PKB<br />

inhibitor programme will be to be able to translate into<br />

the clinic the various read-outs that have been<br />

developed in the laboratory to measure PKB activity.


CANCER THERAPEUTICS/CANCER BIOLOGY<br />

Clinical input is important<br />

It is important to note that clinical input is important<br />

throughout the whole drug discovery process. Indeed,<br />

an initiating event for the PKB inhibitor programme was<br />

a discussion with clinical colleagues about the types of<br />

clinical issues that would need to be addressed in order<br />

for a PKB inhibitor to be turned into an actual drug that<br />

could be used to treat patients with cancer.<br />

Here, an important issue for clinicians is how easy<br />

will it be to administer a new drug to the patient, and<br />

will it require multiple trips to the hospital. For the PKB<br />

project this means investigating whether a PKB inhibitor<br />

can be developed that can be given as a once-a-day pill.<br />

<strong>The</strong> synergistic<br />

interaction between<br />

Institute scientists from<br />

different disciplines,<br />

clinical colleagues at<br />

the <strong>Royal</strong> <strong>Marsden</strong> and<br />

our partnership with<br />

Astex Technology Ltd<br />

is allowing the PKB<br />

inhibitor programme<br />

to progress rapidly<br />

from gene to drug,<br />

with the key objective<br />

of providing faster<br />

patient benefit.<br />

<strong>The</strong> future for PKB inhibitors<br />

At the start of this article we said that the treatment<br />

of cancer patients is undergoing a major move<br />

towards novel anticancer agents that specifically<br />

target the molecular abnormalities of the cancer cell<br />

itself. <strong>The</strong> PKB inhibitor programme is a reflection of<br />

this move. Taking this one step further, it will be<br />

important to determine whether a PKB inhibitor drug<br />

will have most impact in those patients with<br />

abnormalities in the PI3 kinase/PKB pathway. In this<br />

way we can start to personalise cancer treatment for<br />

maximum patient benefit.<br />

A second potential application for a PKB inhibitor<br />

drug in the clinic would be to combine this agent<br />

with an existing anticancer drug. This could be a<br />

conventional chemotherapeutic agent, such as a<br />

taxane or carboplatin, or indeed another molecularly<br />

targeted agent, for example gefitinib (Iressa). <strong>The</strong><br />

principle here is that combining a PKB inhibitor with<br />

an existing drug will give superior patient benefit<br />

compared to using either agent alone.<br />

<strong>The</strong> ultimate objective<br />

of the PKB inhibitor<br />

programme is to offer<br />

a personalised cancer<br />

treatment to the patient<br />

in the clinic.<br />

very different from the cytotoxic drug era, in that we now<br />

seek to develop highly specific drugs directed to distinct<br />

molecular targets and hence with a much more selective<br />

tumour action.<br />

Designer drugs will be<br />

better tolerated than<br />

<strong>Research</strong><br />

Cytotoxic drugs<br />

Historically, <strong>The</strong> Institute and the <strong>Royal</strong> <strong>Marsden</strong> played<br />

leading roles in the design and development of many<br />

of the cytotoxic drugs used for treating cancer<br />

(eg melphalan, chlorambucil, busulphan, raltitrexed,<br />

the platinum class of drugs).<br />

Although this cytotoxic era of drug design and<br />

development dates from the 1940s, cytotoxic drugs still<br />

represent the mainstay of current drug treatment for<br />

cancer. <strong>The</strong>y are particularly effective in testicular cancer<br />

and childhood leukaemia. However, cytotoxic drugs are<br />

not so effective in advanced solid tumours that have<br />

spread around the body.<br />

Three key lessons learned from<br />

the cytotoxic era<br />

Drug resistance is frequent – whether intrinsic or<br />

acquired during treatment.<br />

Combinations or cocktails of drugs are generally<br />

much more effective than single agents.<br />

Although laboratory models are instructive, they<br />

have limitations in predicting clinical usefulness.<br />

<strong>The</strong> new era of drug<br />

development<br />

We are now entering a second era of drug<br />

development: one that seeks to exploit our recent<br />

knowledge of the molecular abnormalities, which result<br />

from mutations of DNA, that drive cancer.<br />

Oncogene addiction<br />

Designer drugs will have a selective anti-tumour action<br />

and will exploit what is known as oncogene addiction<br />

(oncogenes are cancer genes). Oncogene addiction<br />

means that cancer cells become dependent upon, or<br />

addicted to, the very genetic abnormalities which drive<br />

them. Thus, drugs that target the specific cell pathways<br />

(see articles by Dr Michelle Garrett, p. 24 and Dr Pascal<br />

Meier, p. 20, respectively) hijacked by cancer genes will<br />

have a preferential action on malignant cells.<br />

Previous lessons still hold good<br />

However, the issues that we currently face are still<br />

familiar. Firstly, we are seeing resistance develop to the<br />

new generation of drugs. This often occurs not only by<br />

further mutations in the oncogene target but also<br />

because cancers are often driven by several, not just<br />

one abnormality. We need to develop treatments that<br />

tackle multiple genetic changes, and this, as with<br />

current cytotoxic treatments, will involve the use of drug<br />

cocktails. We also need to continue to refine and<br />

improve our laboratory models of cancer.<br />

Figure 1 summarises the new approach of designer<br />

drugs for the cancer genome. Patients will be selected so<br />

that their drug is matched to the precise genetic<br />

abnormalities of their cancers. This requires the parallel<br />

development of drugs and biomarkers for patient selection.

Targeting the BRAF oncogene<br />

Following the discovery of BRAF as an oncogene by<br />

Professor Mike Stratton (Section of Cancer Genetics) and<br />

colleagues in the Cancer Genome Project, we rapidly<br />

initiated a project to discover inhibitors of this particular<br />

target. High throughput screening identified early leads<br />

of possible chemical inhibitor molecules. <strong>The</strong>se are now<br />

being refined using the detailed 3D structure of the<br />

BRAF protein obtained by Professor David Barford<br />

(Section of Structural Biology) and Dr Richard Marais<br />

(Cancer <strong>Research</strong> UK Centre for Cell and Molecular<br />

Biology at <strong>The</strong> Institute). This project is a partnership<br />

with the Wellcome Trust and Astex Technology Ltd.<br />

Targeting the PI3 kinase PIK3CA oncogene<br />

Rapid genome sequencing methods were also used to<br />

discover mutations in another oncogene, the PI3 kinase<br />

PIK3CA. We are developing inhibitors of this kinase in<br />

collaboration with the spin-out company PIramed.<br />

<strong>The</strong>se inhibitors are very potent and selective for the<br />

target and show promising activity in models of cancer,<br />

including brain tumours. In her article (see p. 24),<br />

Dr Michelle Garrett describes progress on a target in<br />

the same cancer-causing pathway, AKT/PKB.<br />

Drugs emerging from these programmes ideally will<br />

be given in cocktails according to the nature of the<br />

spectrum of underlying mutations in the particular cancer.<br />

Targeting cancers that have multiple<br />

molecular abnormalities<br />

We use an alternative approach to tackle cancers with<br />

multiple molecular abnormalities. Here, we target not<br />

the individual oncogenes, but instead the support<br />

systems upon which they are particularly dependent.<br />

One of these is the so-called chaperone protein HSP90.<br />

<strong>The</strong> job of this chaperone is to ensure that many<br />

different cancer-causing proteins adopt the necessary<br />

HSP90 inhibitors may<br />

be particularly effective<br />

because they<br />

simultaneously block<br />

the function of many<br />

different cancer-causing<br />

proteins, giving a<br />

combinatorial effect.<br />

Furthermore, cancer<br />

cells appear to be<br />

especially dependent<br />

on HSP90.<br />

Targeting the chromatin modifying<br />

enzymes (CMEs)<br />

Another set of targets – also expected to give a<br />

powerful effect across many cancers – are the<br />

chromatin modifying enzymes (CMEs). Chromatin is<br />

the packaging material for DNA, and CMEs alter<br />

chromatin to control gene expression. <strong>The</strong>se processes<br />

are deregulated in cancer. We are developing inhibitors<br />

of several CMEs including histone deacetylases, histone<br />

methyltransferases and Aurora kinases. <strong>The</strong>se projects<br />

are in partnership with Chroma <strong>The</strong>rapeutics Ltd.<br />

Targeting the rarer forms of cancer<br />

It is important that we also develop drugs for the more<br />

rare cancers, caused by unusual genetic changes – all<br />

the more because they will not be a priority for large<br />

pharmaceutical companies since they have a low<br />

commercial return as marketable products. Here, we are<br />

working with colleagues in the Section of Paediatric<br />

Oncology to develop drugs that will act on a type of<br />

children’s cancer, known as rhabdomyosarcoma, which<br />

is driven by a specific chromosomal translocation.<br />

Clinical developments<br />

From laboratory bench to the<br />

patient’s bedside<br />

A defining characteristic of the drug development<br />

programme at <strong>The</strong> Institute and <strong>Royal</strong> <strong>Marsden</strong> is the<br />

seamless transition of the most promising candidates<br />

from the bench to bedside. This has required a major<br />

commitment on the part of the <strong>Royal</strong> <strong>Marsden</strong> to<br />

provide clinical facilities fit for purpose in the<br />

demanding environment of early clinical trials in 2005.<br />

This challenge has now been met by the opening of the<br />

ward in the Drug Development Unit (now named the<br />

Oak Foundation Drug Development Centre) at Sutton in<br />

December <strong>2004</strong>. With 16 beds (10 in-patient, 6 day<br />

beds) exclusively for this purpose, and a fully dedicated<br />

clinical research staff of doctors, nurses and others (over<br />

40 in total) this facility is now well placed to play its<br />

role as one of the world’s leading drug development<br />

units in cancer. Figure 2 illustrates the increase in<br />

activity in the Drug Development Unit over the past 2<br />

years as well as the referral pattern over the past 12<br />

months. All tumour types are represented, emphasising<br />

the fact that the various molecular targets being<br />

evaluated are present in most forms of cancer.

Adding value to drugs from industry<br />

Novel agents developed within the Centre for Cancer<br />

<strong>The</strong>rapeutics form the core of our portfolio. However,<br />

we are also conducting trials of a large number of<br />

new drugs available from pharmaceutical companies –<br />

generally aimed at molecular targets in which Centre<br />

scientists have a particular interest. <strong>The</strong>re are<br />

approximately 20 open trials in the Drug Development<br />

Unit (summarised in Table 1). While the majority of<br />

trials involve evaluation of a single agent, we are also<br />

committed to the concept that the activity of an existing<br />

cytotoxic drug (eg carboplatin or a taxane) can be<br />

enhanced by the addition of a novel drug with defined<br />

inhibitory properties on relevant pathways.<br />

Phase I trials<br />

<strong>The</strong> prime purpose of Phase I clinical trials is to evaluate<br />

the toxicity and body distribution (pharmacokinetics) of<br />

a new drug. When dealing with novel molecularly<br />

targeted agents, it is also crucially important that an<br />

assessment is made of the ability of the drug to reach<br />

and inhibit the specific target for which it was designed,<br />

preferably in tumour cells (ie the proof-of-principle or<br />

pharmacodynamic study). This aspect of our work<br />

requires enhanced teamwork and involves colleagues in<br />

radiology and pathology. In addition, the information<br />

obtained from tumour biopsies also can be pivotal in<br />

the evaluation of a new agent. An example is given in<br />

Figure 3, illustrating the inhibition of the molecular<br />

chaperone HSP90 – at well-tolerated doses – by the<br />

HSP90 inhibitor, 17-allylamino 17-demethoxygeldanamycin<br />

(17AAG). <strong>The</strong> particular patient involved,<br />

with progressive metastatic melanoma, has had clear<br />

evidence of sustained benefit from this treatment.<br />

Phase II clinical trials (ie formal clinical trials to monitor<br />

how effective a new drug is in patients) using 17AAG<br />

in melanoma are now underway at the <strong>Royal</strong> <strong>Marsden</strong>.<br />

Tumour efficacy<br />

While not a primary endpoint of Phase I trials, we do<br />

incorporate a careful assessment of tumour efficacy (ie<br />

whether a new drug has an effect in shrinking or<br />

eliminating tumours) in all patients. <strong>The</strong>re is no doubt<br />

that responses are now being seen regularly with a<br />

number of the new drugs in our portfolio. <strong>The</strong>se include<br />

clear tumour shrinkage in patients with non-small cell<br />

lung cancer given an m-TOR inhibitor (m-TOR is a key<br />

signal in the PI3 kinase/PKB pathway), and also a pan-<br />

ERBB inhibitor, as well as prolonged tumour<br />

stabilisation in patients with sarcoma treated with a<br />

broad spectrum or pan-kinase inhibitor.<br />

Hot areas<br />

An important health care goal as the cost of drugs<br />

escalates is the rational selection of patients most likely<br />

to benefit from a particular treatment, as well as<br />

identifying which patients (often the majority) should<br />

not be treated with ineffective and costly drugs. Here,<br />

we predict that appropriate patient identification, using


CANCER THERAPEUTICS<br />

molecular diagnostics, will increasingly feature alongside<br />

new drug development. This will apply equally to the<br />

use of new drugs both as single agents and in novel<br />

combination schedules.<br />

Examples include the key observations linking<br />

mutations of the epidermal growth factor receptor<br />

(EGFR) to the likelihood of a response to EGFR<br />

inhibitors, gefitinib (Iressa) and erlotinib (Tarceva) in<br />

patients with lung cancer.<br />

In addition, Professor Mike Stratton, who leads the<br />

Cancer Genome Project in the UK, has recently<br />

discovered mutations predicted to activate the<br />

ERBB2 receptor in patients with lung cancer<br />

(adenocarcinoma). This opens up the exciting<br />

possibility of being able to detect a further specific<br />

molecular target that will predict response to new<br />

agents in this disease. This approach is being actively<br />

developed within the <strong>Royal</strong> <strong>Marsden</strong> Lung Unit.<br />

Several of the agents under development in our<br />

programme target the PI3 kinase/PKB pathway.<br />

Here, patient selection is also important, in that<br />

tumours bearing mutations of the important tumour<br />

suppressor gene, PTEN, may be particularly<br />

susceptible to this approach. This also applies to<br />

tumours with activating mutations of PI3 kinase<br />

itself (specifically PI3KCA which encodes the P110<br />

·-subunit of the protein molecule). Examples include<br />

glioblastoma, prostate cancer and endometrial<br />

cancer as well as certain patients with colorectal,<br />

gastric and breast cancer. This will certainly form an<br />

important part of our strategy as agents acting on<br />

these targets enter the clinic over the next few years.<br />

A reasonable<br />

assumption underlying<br />

the development of<br />

molecularly targeted<br />

therapy is that new<br />

agents will have their<br />

maximum impact in<br />

selected patients whose<br />

cancers possess the<br />

molecular targets<br />

against which the drug<br />

is designed to act.<br />

Myeloma research:<br />

novel therapeutic approaches<br />

Approximately 3,500 new cases of myeloma are diagnosed<br />

in the UK each year. <strong>The</strong> majority of cases occur over the<br />

age of 60 years, but 20–30% of cases still occur in the<br />

40–60 year age group.<br />

<strong>The</strong> <strong>Royal</strong> <strong>Marsden</strong> NHS<br />

Haemato-Oncology<br />

<strong>The</strong> Section of Haemato-Oncology at <strong>The</strong> Institute and<br />

the Haemato-Oncology Unit at the <strong>Royal</strong> <strong>Marsden</strong> are<br />

committed to improving the outlook for patients with<br />

myeloma by developing novel therapeutic approaches<br />

based on a sound knowledge of the biology of the<br />

disease. In order to do this we have developed an<br />

integrated service, which combines laboratory-based<br />

research looking at the characteristics of myeloma cells,<br />

with a comprehensive clinical service covering<br />

chemotherapy, radiotherapy, stem cell transplantation<br />

and new drugs.<br />

<strong>The</strong> hope is that over<br />

the coming years we will<br />

be able to individualise<br />

patients’ therapy based<br />

on our laboratory studies,<br />

leading to an improved<br />

outlook and survival for<br />

patients with an associated<br />

decrease in side effects<br />

and improvement in<br />

quality of life.<br />

Myeloma background<br />

Myeloma is a malignant blood cancer caused by the<br />

uncontrolled growth of plasma cells. <strong>The</strong>se are a type<br />

of white blood cell that produce antibodies to fight<br />

infections. In myeloma, malignant plasma cells produce<br />

large amounts of abnormal antibodies.<br />

<strong>The</strong> range of clinical effects of myeloma include<br />

bone marrow suppression resulting in an increased<br />

susceptibility to infection, lytic bone lesions (Figure 1),<br />

the production of a paraprotein, spontaneous fractures,<br />

bone pain and renal failure. <strong>The</strong>se clinical effects occur<br />

because of the presence of a malignant plasma-cell<br />

infiltrate within the bone marrow, producing a single<br />

variety of immunoglobulin called a paraprotein.<br />

Currently a cure for myeloma is not possible, but<br />

with the introduction of targeted treatment strategies<br />

the possibility of turning this disease into a chronic<br />

disorder that can be managed over many years is<br />

becoming a reality.<br />

<strong>The</strong> current world standard treatment for myeloma<br />

is an autologous (ie from the same person) stem cell<br />

transplant for patients who are able to tolerate it – a<br />

treatment method originally pioneered at the <strong>Royal</strong><br />

<strong>Marsden</strong>. However, the majority of patients eventually<br />

relapse following this treatment and so there is a need<br />

to integrate novel therapies into standard treatment<br />

strategies. New therapies need to be targeted, based<br />

on an understanding of the biology of myeloma.<br />

Myeloma biology<br />

Myeloma plasma cells and their bone<br />

marrow environment<br />

Myeloma plasma cells exist in the bone marrow in<br />

a complex environment where there are intricate<br />

biological interactions occurring. It is widely recognised<br />

that there are important positive feedback loops in the<br />

bone marrow that favour the survival of myeloma<br />

plasma cells, which involve cytokines.<br />

Cytokines are messenger molecules that regulate<br />

cell function. Important cytokines in myeloma include<br />

IL6, TNF·, IGF, and VEGF – all of which now can be<br />

specifically targeted with drugs. Some of the new drugs<br />

being introduced into the clinic can target these<br />

multiple cytokine feedback loops and have proven to


e very useful. Examples include thalidomide, as well its<br />

more potent derivative lenolidamide (Revlimid), which is<br />

associated with a more favourable side effect profile.<br />

Other drugs such as atiprimod, which also inhibit<br />

multiple cytokine loops, may also prove to be important.<br />

Osteoclasts – the destroyers of bone<br />

Cellular interactions also occur in the bone marrow<br />

between myeloma plasma cells and other cells called<br />

osteoclasts. Osteoclasts are the cells that break down<br />

bone. When osteoclasts are activated by osteoclast<br />

activating factors, which are secreted by the malignant<br />

myeloma plasma cells, this then leads lead to bone<br />

resorption and raised blood calcium levels<br />

(hypercalcaemia). This interaction can be targeted by the<br />

bisphosphonate class of drugs, as well as drugs that target<br />

what is called the RANK ligand/osteoprotegerin pathway.<br />

This provides a novel strategy for the therapeutic inhibition<br />

of myeloma plasma cells as well as osteoclasts.<br />

Genetic studies and<br />

clinical outcome<br />

Single nucleotide polymorphisms (SNPs)<br />

We are aiming to look at the genetic make-up (ie the<br />

DNA sequence) of thousands of myeloma patients to try<br />

and determine why it is that patients develop myeloma,<br />

and also to understand why patients respond differently<br />

to therapy and why certain patients develop side effects<br />

from therapy. Within the DNA sequence, alterations can<br />

occur to a single chemical base (these chemical bases<br />

are called nucleotides). <strong>The</strong>se alterations are called<br />

single nucleotide polymorphisms (SNPs) and within the<br />

structure of a gene there are a number of different SNPs<br />

that can alter the function of the gene.<br />

Having obtained DNA from a mouth swab or blood<br />

sample we are able to detect up to 10,000 SNPs in a<br />

single experiment, and then go on and correlate the SNP<br />

pattern with the patients’ clinical experience. We are<br />

using this technique in current research to determine<br />

why up to 30% of patients experience peripheral<br />

neuropathy side effects (ie side effects due to damage<br />

to the peripheral nerves that go out from the brain and<br />

spinal cord to the muscles, skin, internal organs and<br />

glands) with thalidomide or bortezomib (Velcade).<br />

Genetics and patient outcomes<br />

Although there are a number of prognostic staging<br />

systems (ie methods for placing a patient into a<br />

particular type of clinical category) that can separate<br />

myeloma patients into groups which are likely to have<br />

different outcomes, most of these staging systems have<br />

been around for many years and they neither<br />

incorporate recent developments in myeloma science,<br />

nor are they used regularly by physicians for deciding<br />

on treatment options.<br />

As part of a current trial (Myeloma IX) we are<br />

performing a comprehensive genetic analysis of patient<br />

myeloma cells, linking the findings with response to<br />

treatment and survival. <strong>The</strong> ultimate aim is to identify a<br />

series of genes that can predict patients’ response to<br />

therapy. In particular, we wish to identify patients who<br />

will respond poorly to standard treatments so that novel<br />

treatment approaches can be offered early to this<br />

subset of patients.<br />

Genetic studies and<br />

new therapies<br />

Oncogenes<br />

It is known that the integrity of the DNA and RNA<br />

within myeloma plasma cells is damaged, and recent<br />

Figure 1.<br />

Lytic bone lesions,<br />

which are readily seen<br />

on plain skeletal X-rays,<br />

are a major problem in<br />

multiple myeloma,<br />

where they cause back<br />

pain and increase the<br />

risk of skeletal fracture.<br />

<strong>The</strong> lesions appear as<br />

darkened areas in the<br />

bone. At the <strong>Royal</strong><br />

<strong>Marsden</strong> we are<br />

exploring the use of<br />

new imaging<br />

modalities, such as<br />

PET scanning.<br />

35


studies have suggested that patients with different<br />

chromosomal characteristics have different prognoses.<br />

Characterising these differences further is important<br />

because identifying the damaged genes will allow us to<br />

target therapies to these genes. One important strategy<br />

to identify deregulated genes relies upon the<br />

identification and targeting of oncogenes (genes that<br />

have been deregulated, often because of recurrent<br />

chromosomal rearrangements).<br />

Oncogenes are regularly found in chromosome 14.<br />

An example is the oncogene FGFR3 (fibroblast growth<br />

factor receptor 3), which is deregulated by genetic<br />

translocation (where a section of DNA in the<br />

chromosome breaks but is then reinserted in the wrong<br />

place). <strong>The</strong> FGFR3 oncogene occurs in 15% of myeloma<br />

patients. Our previous studies have characterised where<br />

the FGFR3 translocation occurs (in position 4;14) and<br />

also demonstrated that cases with this translocation<br />

have a distinct gene expression profile.<br />

We are now investigating<br />

how to specifically target<br />

the FGFR3 oncogene in<br />

the clinical environment<br />

using small molecule<br />

tyrosine kinase inhibitors.<br />

Initial results, based on<br />

pre-clinical and clinical<br />

data suggest this may<br />

prove to be an excellent<br />

treatment option for<br />

well-defined subsets<br />

of patients.<br />

Another recurrent chromosome abnormality – a<br />

translocation in position 11;14 – deregulates a group of<br />

proteins called D group cyclins, which are involved in<br />

helping regulate cell growth and cell division. Targeting<br />

gene deregulations associated with D group cyclins may<br />

be a therapeutic option for 30–40% of myeloma patients.<br />

Defining new biologically<br />

relevant targets<br />

Proteosome inhibition<br />

Other important therapeutic advances have come from<br />

the study of the molecular pathogenesis of myeloma<br />

(Figure 2). <strong>The</strong> current, most clinically relevant of these<br />

therapeutic advances, is proteosome inhibition using<br />

bortezomib. <strong>The</strong> proteosome is an important intracellular<br />

organelle, which degrades signalling molecules in a<br />

structured fashion, allowing the complex inter- and<br />

intracellular cross-talk that is essential for either normal<br />

or malignant cell activity. It is possible to reversibly<br />

inhibit the proteosome, without causing excess toxicity,<br />

and it has now been shown that malignant plasma cells<br />

can be selectively killed in this way.<br />

Important targets of proteosome inhibition include<br />

the NFÎB/ÎIB complex and cell signalling molecules.<br />

In our laboratory programme we are trying to<br />

develop more such molecules, selectively targeting<br />

other pathways, to give us further therapeutic<br />

options aimed at long-term control of the myeloma<br />

clone. In this context, an important plasma-cell<br />

specific pathway, which may set plasma cells apart<br />

from other cells within the body, is their ability to<br />

produce paraprotein. <strong>The</strong> cellular response within the<br />

plasma cells enabling them to produce these<br />

paraproteins requires an adaptive change and this<br />

can be specifically targeted. With this in mind, we<br />

are specifically investigating the role of the HSP90<br />

protein inhibitor, a drug developed in <strong>The</strong> Institute.<br />

By targeting different areas in the plasma-cell<br />

specific process we hope to increase the effects of<br />

the HSP90 inhibitor. Interestingly, based on its mode<br />

of action, bortezomib is likely to work synergistically<br />

with HSP90 inhibitors. It seems likely that many new<br />

agents will work better in combination and we are<br />

specifically working in the laboratory to develop<br />

model systems for the evaluation of such<br />

combinations, which may then be taken forward into<br />

the clinical setting.

that we can make quick and efficient steps forward in laboratory developments into the clinic, so that patients longer remain located<br />

within the bone marrow<br />

<strong>The</strong> initiating events for<br />

myeloma are thought to<br />

involve chromosomal<br />

later events involve<br />

immune system<br />

mutations of either RAS<br />

or p53 oncogenes,<br />

together with other<br />

as yet ill-defined<br />

genetic lesions.<br />

We have shown that thalidomide can enhance the<br />

immune system – in particular natural killer (NK) cells<br />

– which work against the myeloma plasma cells. <strong>The</strong>se<br />

laboratory and targeted treatment approaches are<br />

complemented by our transplant programme, which is<br />

aimed at using dual autologous (ie same person) and<br />

mini-allogeneic (ie different people) transplants to both<br />

stabilise the malignant clone and then to introduce<br />

donor T-cells in an environment where it is possible to<br />

benefit from the graft versus myeloma effect. This T-cell<br />

immunomodulation is relevant clinically and provides a<br />

way of safely performing an allogeneic transplant in<br />

older patients.<br />

We firmly anticipate<br />

that myeloma will<br />

become a chronic<br />

disease, which can be<br />

managed long-term<br />

without impacting<br />

significantly on the<br />

quality of life of patients.<br />

CANCER THERAPEUTICS<br />

Colorectal<br />

Cancer<br />

New therapies for colorectal cancer<br />

Colorectal cancer is one of most common cancers<br />

worldwide and in the UK alone, over 35,000 new<br />

cases are diagnosed each year.<br />

Stages of colorectal cancer<br />

Improving outcomes<br />

after surgery<br />

<strong>The</strong> use of chemotherapy following surgery, a procedure<br />

known as adjuvant therapy, is well established for<br />

patients with colorectal tumours involving local lymph<br />

nodes (Duke’s C cancer). With Duke’s C cases, adjuvant<br />

therapy has been shown to reduce the chance of<br />

relapse and improve survival following surgery to<br />

remove the primary colorectal tumour. In contrast, for<br />

those patients with no regional lymph node involvement<br />

(Duke’s B cancer), the role of adjuvant chemotherapy<br />

has been far less clear. However, data from two large<br />

randomised Phase III trials, QUASAR (UK led) and<br />

MOSAIC (European) now indicate that adjuvant<br />

chemotherapy is beneficial for Duke’s B patients.<br />

Oncology and Head of the<br />

Gastrointestinal Unit at <strong>The</strong><br />

<strong>Royal</strong> <strong>Marsden</strong> NHS<br />

Foundation Trust<br />

A significant number of patients present with early<br />

stage colorectal cancer and are suitable for<br />

potentially curative surgery. However, a proportion of<br />

these patients are at risk of cancer recurrence and<br />

strategies to identify these subgroups and develop<br />

preventive therapeutic strategies have been a key<br />

area in attempting to improve outcomes from the<br />

disease.<br />

Approximately 25% of patients with colorectal<br />

cancer will present with advanced disease or<br />

develop metastatic disease despite earlier therapy.<br />

<strong>The</strong> development of effective treatments for this<br />

group of patients is also of paramount importance.<br />

<strong>The</strong> <strong>Royal</strong> <strong>Marsden</strong><br />

Gastrointestinal Unit<br />

has a critical role in<br />

contributing to, and<br />

in leading research<br />

into the treatment of<br />

colorectal cancer, both<br />

in the national and<br />

international arenas.<br />

Bolus versus a continuous infusion of<br />

adjuvant chemotherapy<br />

Currently, the standard length of time of adjuvant<br />

chemotherapy using bolus (ie repeated short injections)<br />

5-fluorouracil (5FU) is 6 months. However, there is<br />

debate over the optimal duration of treatment and on<br />

whether or not adjuvant chemotherapy given as a<br />

constant continuous infusion might provide better<br />

suppression of the growth of cancer cells. This question<br />

has been addressed in the SAFFA randomised Phase III<br />

multicentre UK study. <strong>The</strong> SAFFA study was designed<br />

and conducted by the Gastrointestinal Unit, and<br />

compared whether 3 months of continuous infusion of<br />

5FU was equivalent to 6 months of bolus 5FU in<br />

patients following surgery for colorectal cancer. <strong>The</strong><br />

results, presented and discussed at the <strong>2004</strong> American<br />

Society for Clinical Oncology (ASCO) annual meeting,<br />

indicated equivalence between the two treatments and<br />

importantly, that shortening the duration of<br />

chemotherapy with infused 5FU did not compromise<br />

patient outcomes.<br />

An analysis of the Duke’s B patients in the SAFFA<br />

study has also been undertaken. Duke’s B patients, with<br />

at least one of a defined set of risk factors, who are<br />

treated with adjuvant chemotherapy, are predicted to<br />

have a poorer outcome than patients who do not have<br />

at least one of a defined set of risk factors. Such<br />

knowledge may help select patients from this group for<br />

adjuvant therapy.


<strong>The</strong> duration of<br />

adjuvant chemotherapy<br />

is an important area of<br />

research and further<br />

studies are being<br />

designed worldwide<br />

to address this issue.<br />

<strong>The</strong>rapy before surgery<br />

Treatment of potentially operable tumours before<br />

surgery has advantages in certain groups of patients.<br />

Advances in surgical techniques, including total<br />

mesorectal excision, have improved rates of relapse in<br />

rectal cancers but further progress is needed. <strong>The</strong><br />

EXPERT study designed and undertaken by the<br />

Gastrointestinal Unit, aims to investigate the use of preoperative<br />

therapy to reduce the rate of relapse in rectal<br />

cancers. Here, high definition magnetic resonance<br />

imaging (MRI) has been used to identify patients with<br />

operable rectal cancer that displays features indicative<br />

of high-risk relapse. <strong>The</strong>se high-risk relapse patients<br />

have been treated using combination chemotherapy<br />

(capecitabine and oxaliplatin), followed by<br />

chemoradiotherapy and then subsequent surgery. This<br />

approach has resulted in a high rate of tumour shrinkage<br />

and successful surgery and the results of the study were<br />

presented at the 2005 ASCO Gastrointestinal Symposium<br />

held in Miami, USA, in January.<br />

Liver metastases in colorectal cancer<br />

<strong>The</strong> liver is the most common site for secondary spread<br />

from colorectal cancer and in a significant proportion of<br />

patients is the only organ involved. A small proportion<br />

of patients have liver metastases that can be removed<br />

by surgery, a strategy known to improve disease-free<br />

time and which may potentially result in cure.<br />

However, it is recognised that chemotherapy,<br />

particularly including oxaliplatin, may improve the<br />

operability of liver metastases and therefore further<br />

improve outcomes. Nevertheless, there are currently no<br />

prospective data on this issue. At the <strong>Royal</strong> <strong>Marsden</strong>,<br />

the Gastrointestinal Unit is running a Phase II nonrandomised<br />

study of capecitabine (an oral pro-drug<br />

of 5FU) plus oxaliplatin, a highly active chemotherapy<br />

combination in colorectal cancers, pre- and post-liver<br />

resection, and will eventually provide some of the<br />

first data with this drug combination in this<br />

important setting.<br />

Making progress with<br />

new drugs<br />

<strong>The</strong> emergence of several new drugs – including<br />

capecitabine, oxaliplatin and irinotecan – in the last<br />

decade has had a great impact on the treatment of<br />

colorectal cancer. Various combinations, schedules and<br />

use as first line and salvage therapies have improved<br />

survival and quality of life for sufferers of the disease.<br />

However, new approaches are desperately needed to<br />

achieve further improvements in care.<br />

As we begin to gain a<br />

greater understanding<br />

of the biological<br />

processes governing<br />

the development of<br />

colorectal cancer, new<br />

therapeutic targets have<br />

been identified and<br />

exciting new treatments<br />

for colorectal cancer<br />

successfully developed.<br />

Cetuximab<br />

Cetuximab (Erbitux) – an inhibitor of the<br />

epidermal growth factor receptor<br />

<strong>The</strong> epidermal growth factor receptor (EGFR) is a cell<br />

membrane receptor whose activation is thought to<br />

contribute to cancer development and progression.<br />

EGFR has a portion of the molecule that is outside the<br />

cell and a portion within the cell (Figure 1). Cetuximab<br />

is a monoclonal antibody that targets the outer portion<br />

of EGFR, thereby blocking its activation (Figure 1). This<br />

has generated a huge amount of interest in colorectal<br />

cancers known to overexpress EGFR. On the basis of a<br />

pivotal randomised Phase II European trial led by<br />

Professor Cunningham, cetuximab was licensed for use<br />

in EGFR positive, irinotecan-refractory colorectal cancer<br />

in June <strong>2004</strong>.<br />

<strong>The</strong> trial randomised patients with colorectal cancer<br />

resistant to irinotecan therapy (many of whom were<br />

heavily pre-treated) between irinotecan plus<br />

cetuximab or cetuximab alone treatment options.<br />

Responses to therapy were seen in both groups, with<br />

a larger benefit seen in the irinotecan plus<br />

cetuximab group (response rate of 23%). Cetuximab<br />

was therefore able to reverse resistance to prior<br />

irinotecan chemotherapy in a proportion of patients<br />

and provide a further treatment option to those<br />

patients for whom further therapy is extremely<br />

limited. An example of a response to cetuximab<br />

monotherapy is shown in Figure 2.<br />

<strong>The</strong> study was published in the New England Journal of<br />

Medicine in July <strong>2004</strong> and has served as a catalyst for the<br />

implementation of several new Phase II and III studies of<br />

cetuximab in combination with chemotherapy agents<br />

both in the first and second line treatment of colorectal<br />

cancer. It has provided a significant contribution to<br />

developing effective therapies for patients with pretreated<br />

cancer, a group that is assuming greater<br />

importance. Furthermore, other ways to target EGFR are<br />

in development; gefitinib (Iressa) is a drug that acts on<br />

the inner portion of the EGFR (Figure 1) and a trial<br />

combining this drug with chemotherapy in patients with<br />

colorectal cancer has recently been completed in the<br />

unit. <strong>The</strong> results are awaited with interest.<br />

Bevacizumab: interfering with the blood<br />

supply to tumours<br />

For decades we have known that tumours are able to<br />

stimulate their own blood supply in order to continue to<br />

grow, a process called tumour angiogenesis. <strong>The</strong> blood<br />

supply is often chaotic and inefficient in delivering<br />

oxygen to the tumour. <strong>The</strong> lack of oxygen further<br />

stimulates new tumour blood vessel growth. One of the<br />

main stimulants of angiogenesis is a small molecule<br />

called vascular endothelial growth factor (VEGF).<br />

Bevacizumab is a drug that targets VEGF and therefore<br />

interferes with the growth of new vessels.<br />

A large Phase III study in the USA published last<br />

year indicated that adding bevacizumab to<br />

chemotherapy in patients receiving treatment for the<br />

first time resulted in improved response to treatment<br />

and survival. <strong>The</strong> Gastrointestinal Unit is currently<br />

recruiting patients with colorectal cancer into several<br />

international trials of bevacizumab and chemotherapy<br />

to further characterise potential benefits of this exciting<br />

new therapy.


CANCER THERAPEUTICS<br />

Future directions<br />

<strong>The</strong> new targeted therapies, including cetuximab and<br />

bevacizumab are very much in the spotlight and the next<br />

year is likely to see the development of these treatments<br />

in both advanced and early stage colorectal cancer. <strong>The</strong><br />

Gastrointestinal Unit aims to be at the forefront of this<br />

research and a number of projects utilising these and<br />

other novel agents are in development:<br />

A multicentre European study of cetuximab in<br />

combination with chemotherapy and radiotherapy as<br />

curative treatment for rectal cancers is planned and<br />

will be led and managed by the Gastrointestinal Unit.<br />

Increasingly, combining targeted agents in an<br />

attempt to knock out several cancer mechanisms<br />

simultaneously will be a key area of research.<br />

It is also crucial to identify which patients are most<br />

likely to respond to these therapies on the basis of<br />

individual tumour characteristics, in order that<br />

therapeutic management can be tailored to<br />

the individual.<br />

<strong>The</strong> identification of appropriate patients for therapy<br />

and inclusion in clinical trials is vital to the continuing<br />

progress in clinical research made by the<br />

Gastrointestinal Unit. Here, we acknowledge the<br />

willingness of our patients to participate in clinical trials<br />

in colorectal cancer. We continue to aim to provide them<br />

with an ongoing and strong multidisciplinary<br />

environment and a commitment from all members of<br />

the research team.<br />

CANCER THERAPEUTICS<br />

Skin Cancer<br />

Melanoma: our understanding of the<br />

disease increases but prevention is still<br />

the best medicine<br />

Excessive exposure to ultraviolet (UV) radiation is the<br />

major risk factor for melanoma, especially burning and<br />

blistering in childhood and teenage years. Most early<br />

melanomas have a characteristic appearance and initially<br />

remain localised. For these reasons the disease is<br />

amenable to prevention and early diagnosis.<br />

Mr J Meirion Thomas is a<br />

Consultant Surgeon in the<br />

Skin Cancer and Melanoma<br />

Unit at <strong>The</strong> <strong>Royal</strong> <strong>Marsden</strong><br />

NHS Foundation Trust<br />

Melanoma is the least<br />

common but most dangerous<br />

skin cancer<br />

Despite the fact that melanoma is the least common<br />

skin cancer, its incidence is nevertheless rising faster<br />

than any other cancer.<br />

In the UK, the incidence of melanoma approximately<br />

doubles every 10–15 years.<br />

Melanoma is the third most common cancer in<br />

women under 40 years of age and the second most<br />

common cancer in males under 40 years of age.<br />

<strong>The</strong>re are 7,000 cases of melanoma diagnosed every<br />

year in the UK and 1,600 deaths, accounting for 1%<br />

of all cancer deaths.<br />

Prognosis and depth of<br />

penetration of a melanoma<br />

into the skin<br />

<strong>The</strong>reafter, there is a linear relationship between tumour<br />

thickness and risk of recurrence. For example, the risk of<br />

recurrence over a 5-year period at 2 mm is 15–20%,<br />

and at 5 mm there is a 60–70% risk of recurrence.<br />

Recent advances in best<br />

practice for melanoma surgery<br />

For some years now there has been debate about what<br />

margin of normal-looking skin should be removed when<br />

poor prognosis melanomas (as defined by a tumour<br />

thickness of at least 2 mm) are excised. <strong>The</strong> issue has<br />

been addressed recently in a study carried out by <strong>The</strong><br />

Institute and the <strong>Royal</strong> <strong>Marsden</strong>.<br />

<strong>The</strong> study compared removal of a 1 cm as opposed<br />

to a 3 cm radius of normal-looking skin around the<br />

melanoma. A total of 900 patients were entered into<br />

the trial, half into the 1 cm margin and half into the 3<br />

cm margin group.<br />

<strong>The</strong> trial was coordinated from <strong>The</strong> Institute’s Section<br />

of Clinical Trials (Gill Coombes, Senior Clinical Trials<br />

Manager; Trial Statisticians, Roger Ahern and Judith<br />

Bliss). Previously, four randomised controlled trials of<br />

good prognosis melanoma had failed to show any<br />

advantage for wider excision. Our trial was the first to<br />

investigate poor prognosis melanoma. <strong>The</strong> study, which<br />

was published in the New England Journal of Medicine,<br />

found that patients with a 1 cm margin were more likely<br />

to have a recurrence than those with a 3 cm margin.<br />

Follow-up of patients is continuing in order to detect<br />

any influence on overall survival.<br />

About 70% of melanomas are of the superficial<br />

spreading variety (Figure 1). <strong>The</strong>se have characteristic<br />

physical signs (irregular border, differential pigmentation<br />

and central depigmentation). <strong>The</strong>re is a good prognosis<br />

for the superficial spreading variety of melanoma, for a<br />

variable period of time, possibly several years, before it<br />

transforms into its penetrating and dangerous<br />

counterpart. <strong>The</strong> prognosis of a melanoma is determined<br />

by its depth of penetration into the skin. This is known<br />

as Breslow tumour. If the tumour thickness is less than<br />

0.76 mm, then the risk of recurrence is extremely low.


Figure 1.<br />

Superficial spreading<br />

melanoma.<br />

This is the first trial to<br />

have ever shown that<br />

the amount of normallooking<br />

skin removed<br />

from around a<br />

melanoma influences<br />

the patient’s outcome.<br />

<strong>The</strong> findings are<br />

important because they<br />

suggest that a small<br />

number of patients with<br />

thick melanoma may be<br />

cured by a wider<br />

margin of excision.<br />

Recent advances in systemic<br />

therapies for melanoma<br />

Under the direction of Professor Martin Gore, Head of<br />

the hospital’s Skin Cancer and Melanoma Unit, the <strong>Royal</strong><br />

<strong>Marsden</strong> and <strong>The</strong> Institute have made a significant<br />

contribution to the development and investigation of<br />

systemic therapies for melanoma. <strong>The</strong> Unit, together with<br />

colleagues at <strong>The</strong> Institute, performed the first cancer<br />

gene therapy trial in the UK, and over the last 10 years<br />

has also been one of the leading recruiters into<br />

European Organisation for <strong>Research</strong> and Treatment of<br />

Cancer (EORTC) trials investigating the use of interferon<br />

in metastatic melanoma.<br />

Currently, an exciting project, led by Dr Tim Eisen<br />

(Section of Medicine) and Dr Richard Marais (Cancer<br />

<strong>Research</strong> UK Centre for Cell and Molecular Biology) is<br />

underway to exploit known genetic abnormalities<br />

present in 85% of melanomas. <strong>The</strong>se abnormalities<br />

affect a molecular signalling pathway in melanoma cells<br />

(the RAS/RAF pathway) and a number of drugs are now<br />

in development to try to block this pathway.<br />

Recent advances in the<br />

treatment of in-transit<br />

metastatic melanoma<br />

<strong>The</strong> <strong>Royal</strong> <strong>Marsden</strong> has also made a significant<br />

contribution towards the treatment of in-transit metastatic<br />

melanoma. Commonly, melanoma disseminates via<br />

lymphatic vessels and tumour cells can become trapped in<br />

these en route (ie in-transit) between the primary tumour<br />

site and the regional lymph nodes. This results in the<br />

development of multiple tumour nodules within the skin<br />

and subcutaneous tissues, which can ulcerate and can<br />

cause morbidity to an extent that amputation may<br />

become necessary for palliative treatment.<br />

Treatment of these tumour nodules within the skin<br />

by carbon dioxide laser vaporisation is a technique that<br />

43


<strong>The</strong> <strong>Royal</strong> <strong>Marsden</strong> is<br />

the only hospital in<br />

England and Wales that<br />

offers HILP using TNF·.<br />

Figure 2.<br />

Pre- and post-carbon<br />

dioxide laser vaporisation.<br />

was developed and evaluated exclusively at the <strong>Royal</strong><br />

<strong>Marsden</strong>, and is now in widespread use. Regional<br />

disease in most patients can be controlled by carbon<br />

dioxide laser vaporisation treatment three or four times<br />

per year, in a daycare setting (Figure 2).<br />

However, as the disease accelerates, a proportion of<br />

patients then will require treatment by what is called<br />

hyperthermic isolated limb perfusion (HILP). Using HILP,<br />

the blood circulation to a tumour-affected limb is first<br />

stopped using a tourniquet, and the isolated limb then<br />

perfused with the drug melphalan (originally synthesised<br />

at <strong>The</strong> Institute) together with recombinant human<br />

tumour necrosis factor alpha (TNF·) (Figure 3). However,<br />

because of the profound systemic toxicity of TNF· on the<br />

normal cardiovascular circulation, it is essential to have a<br />

leak-monitoring system in place that will rapidly detect<br />

any leakage of TNF· across the tourniquet, so that HILP<br />

can be terminated if necessary. In order to achieve this,<br />

the radioactive isotope 99m Tc, attached to human serum<br />

albumin, is injected into the perfusion mixture as soon as<br />

the isolated limb circulation is established and any<br />

leakage of 99m Tc that then occurs across the tourniquet<br />

can be detected real-time using a radiation detector<br />

positioned over the patient’s heart. This operation<br />

involves cooperation between surgeon, anaesthetist,<br />

perfusionist and physicist.<br />

<strong>The</strong> controversy of selective<br />

lymphadenectomy –<br />

a 113-year-old theory<br />

that remains unproven<br />

A major and controversial area of current melanoma<br />

research was begun by Dr Herbert Snow, who was a<br />

surgeon at the Cancer Hospital, Brompton (now the<br />

<strong>Royal</strong> <strong>Marsden</strong>) between 1876 and 1905. Dr Snow<br />

published a pivotal paper in <strong>The</strong> Lancet on 15th October<br />

1892 entitled ‘Melanotic cancerous disease’. In his<br />

paper, Dr Snow gives a remarkably accurate account of<br />

the natural history of melanoma and its prognosis<br />

according to stage. He made the observation that when<br />

patients presented with bulky metastatic nodal disease,<br />

they invariably died of distant spread. He therefore<br />

proposed the operation of anticipatory lymphadenectomy<br />

and stated the following: ‘It is essential to remove<br />

whenever possible those glands which first receive the<br />

infected protoplasm and bar its entrance into the blood<br />

before they undergo increase in bulk.’<br />

Dr Snow’s intuitive extrapolation of early nodal<br />

surgery became known as elective lymph node dissection<br />

(ELND) and in 1992 evolved into the operation of<br />

selective lymphadenectomy, which is regarded as<br />

‘standard of care’ in the USA and other countries.<br />

Selective lymphadenectomy is based on the concept<br />

of the sentinel node (defined as the first drainage lymph<br />

node involved by the metastatic process). <strong>The</strong> sentinel<br />

node can be reliably identified by a combination of dye<br />

and radioactive colloid injected into the skin at the site<br />

of the primary tumour. If the sentinel node is positive for<br />

early metastatic disease the patient is advised to<br />

undergo lymphadenectomy.<br />

<strong>The</strong> problem is that 113 years later on, Dr Snow’s<br />

theory remains unproven.

To add to the controversy, two publications from the<br />

Skin Cancer and Melanoma Unit have suggested an<br />

iatrogenic complication (ie a complication resulting<br />

from the treatment itself) of selective lymphadenopathy<br />

– namely an increased incidence of in-transit disease.<br />

<strong>The</strong> hypothesis is that synchronous wide excision of<br />

the primary tumour and local lymphadenopathy means<br />

that the normal lymphatic flow is disturbed<br />

and obstructed so that melanoma cells become<br />

entrapped within lymphatic channels – and there they<br />

will progress to form tumour nodules in the skin and<br />

subcutaneous tissue.<br />

However, there is a positive corollary to the above<br />

warning. Dr Eleanor Moskovic in the Department of<br />

Radiology at the <strong>Royal</strong> <strong>Marsden</strong> has shown that elective<br />

inguinal node dissection for squamous carcinoma of the<br />

vulva can be replaced by ultrasound surveillance and<br />

ultrasound-guided fine-needle aspiration cytology when<br />

the nodes look suspicious. Selective lymphadenectomy<br />

can be undertaken based on the identification of nodal<br />

deposits as small as 4 mm. We have now started an<br />

identical surveillance programme for melanoma after<br />

wide excision.<br />

Where does this leave us<br />

<strong>The</strong> future<br />

Despite step-by-step improvements in our<br />

understanding of melanoma and its treatment, the<br />

reality is that this devastating disease is largely brought<br />

about by excessive exposure to UV radiation, particularly<br />

during childhood and teenage years. Melanoma is<br />

essentially a preventable disease, and as such, priorities<br />

for the future should include a national programme of<br />

public education about the disease, as well as a<br />

national programme of early diagnosis.<br />

Rapid advances in the diagnosis<br />

<strong>The</strong> development of combined positron emission<br />

Two key areas of rapid<br />

development in<br />

nuclear medicine<br />

Nuclear medicine involves the use of radioactive isotopes<br />

in the diagnosis and treatment of many diseases but has<br />

an especially important role in oncology. Whilst many<br />

diagnostic and therapeutic nuclear medicine techniques<br />

are used in day-to-day routine patient management<br />

there are two key areas that have shown rapid recent<br />

development, with evidence of improvement in patient<br />

management and care.<br />

Positron emission tomography (PET) scanning uses<br />

radiopharmaceuticals such as 18 F-fluorodeoxyglucose<br />

(FDG) to detect abnormally increased glucose<br />

metabolism in malignant cells to help to pinpoint<br />

cancer more sensitively and to monitor treatment<br />

more effectively. <strong>The</strong> most recent advance in this<br />

modality is in the development of combined PET/CT<br />

scanners that can monitor tumour function (PET) as<br />

well as detect structural changes (CT) in a single scan,<br />

maximising the advantages of each type of scan.<br />

Targeted radionuclide therapy employs a number of<br />

different radiopharmaceuticals that can specifically<br />

target cancer cells, resulting in a therapeutic radiation<br />

dose to tumour tissue rather than normal tissues.<br />

Whilst this technique has been successfully employed<br />

for many years in a number of rare cancers including<br />

thyroid and neuroendocrine tumours, novel agents<br />

have now been developed for a wider range of<br />

common tumours, including lymphoma.<br />

the extra information<br />

gained from combined<br />

PET/CT imaging is<br />

incremental and<br />

complementary to<br />

standard imaging in a<br />

number of cancers<br />

and positively affects<br />

patients’ clinical<br />

management in as<br />

many as 30% of cases<br />

compared to standard<br />

techniques.<br />

Work is currently underway at the <strong>Royal</strong> <strong>Marsden</strong><br />

PET/CT Unit in collaboration with Professor Janet<br />

Husband (Head of the Department of Diagnostic<br />

Radiology) and a number of clinical units to further<br />

evaluate the role and efficacy of FDG-PET in a number<br />

of clinical situations, in order that the use of this<br />

valuable resource can be optimised to help tailor<br />

treatment protocols in individual patients.<br />

Recurrent colorectal cancer<br />

In collaboration with Professor David Cunningham and<br />

colleagues in the Gastrointestinal Unit, this project is<br />

prospectively evaluating the contribution of FDG-PET<br />

in clinical decision-making in patients in whom there<br />

is suspicion of recurrent cancer as a result of a positive<br />

tumour marker blood test (carcino-embryonic antigen<br />

– CEA), but in whom standard imaging tests such as<br />

CT are negative.


Lung cancer<br />

In collaboration with Dr Mary O’Brien and colleagues in<br />

the <strong>Royal</strong> <strong>Marsden</strong>’s Lung Unit, this project is evaluating<br />

the contribution of FDG-PET/CT to the speed with<br />

which therapy is instigated when used early on in the<br />

investigation pathway. By using FDG-PET/CT at an early<br />

stage soon after diagnosis it is possible that patients’<br />

treatment pathways will be accelerated with a reduction<br />

in delay to first treatment.<br />

Figure 1 shows a combined FDG-PET/CT scan (PET<br />

colour scale, CT grey scale) of a patient with lung cancer.<br />

<strong>The</strong> tumour (colour) can easily be differentiated from<br />

collapsed lung distal to the tumour (grey) that is not<br />

involved by cancer. This type of information may be very<br />

helpful in planning radiotherapy, with the potential to<br />

delineate more accurately the boundaries of the tumour<br />

compared to using CT alone.<br />

Oesophageal cancer<br />

Many patients with apparently operable oesophageal<br />

cancer relapse after surgery because of small areas of<br />

disease, which were undetectable by conventional<br />

investigation at the time of surgery. FDG-PET is being<br />

used to routinely stage patients with apparently operable<br />

oesophageal cancer to measure its impact on subsequent<br />

patient management (in collaboration with Mr William<br />

Allum, Gastrointestinal Unit). It is possible that a number<br />

of patients will be able to avoid futile surgery and receive<br />

more appropriate treatment, eg chemotherapy. A further<br />

project is planned in collaboration with Dr Diana Tait in<br />

the Department of Radiotherapy to evaluate the role of<br />

FDG-PET in planning radiotherapy in oesophageal cancer.<br />

Lymphoma<br />

In collaboration with Professor David Cunningham and<br />

colleagues in the Lymphoma Unit, this project will<br />

prospectively evaluate the role of FDG-PET/CT in clinical<br />

decision making in patients who have received primary<br />

chemotherapy but who are left with a residual tumour<br />

mass in which it is not possible to differentiate residual<br />

active tumour, which requires further treatment with<br />

radiotherapy, from post-treatment scar tissue.<br />

Further projects are underway or being planned to<br />

evaluate the role of FDG-PET/CT in radiotherapy planning.<br />

Areas of current interest include head and neck, lung and<br />

oesophageal cancer as well as lymphoma.<br />

collapsed lung<br />

tumour<br />

FDG-PET/CT in evaluating<br />

response to treatment<br />

Monitoring tumour metabolism has the potential to be<br />

a more sensitive method in evaluating response to<br />

anticancer treatments, because changes in tumour<br />

metabolism often occur before a reduction in tumour<br />

size is seen – a parameter currently used to assess<br />

response with standard imaging methods. Many novel<br />

anticancer drugs act by inhibiting specific aspects of<br />

tumour metabolism rather than by the direct killing of<br />

tumour cells as occurs with standard chemotherapy.<br />

Successful treatment with these novel agents may<br />

therefore be more easily appreciated using techniques<br />

that measure tumour (a)<br />

metabolism rather than<br />

size reduction of the<br />

tumour.<br />

Figure 2 shows a<br />

patient with a<br />

gastrointestinal stromal<br />

tumour in the liver and (b)<br />

pelvis (Figure 2a). Two<br />

months after starting<br />

imatinib treatment, the<br />

activity of the tumour<br />

has completely resolved<br />

(Figure 2b).<br />

We are using FDG-PET/CT to measure treatment<br />

response to at least three novel anticancer agents in<br />

collaboration with colleagues in the Drug Development<br />

Unit. Although the mechanism of action of these drugs<br />

may differ, there is usually a common downstream effect<br />

on tumour glucose transport and metabolism that can<br />

be monitored by FDG-PET/CT.<br />

Radioimmunotherapy<br />

One of the most promising advances in radionuclide<br />

treatment is radio-immunotherapy using isotopetumour<br />

L<br />

B<br />

Targeted radionuclide therapy<br />

Targeted therapy using therapeutic radioisotopes offers<br />

several advantages compared with other cancer<br />

treatments. Acting systemically, this approach allows<br />

multiple tumour sites to be treated simultaneously with<br />

relative sparing of healthy surrounding tissues. As a<br />

result, toxicity is very low in comparison with other<br />

systemic therapies and treatment is well tolerated.<br />

Alternatives to the use of radioactive iodine<br />

Radioactive iodine, for example, has been the mainstay<br />

of post-surgical treatment for differentiated thyroid<br />

cancer for over 50 years. In addition to therapeutic beta<br />

particles, iodine also emits unwanted high-energy<br />

gamma rays, which pose a significant radiation hazard<br />

to staff and carers. Patients undergoing high-activity<br />

treatment must therefore be nursed for several days<br />

in dedicated, lead-lined isolation rooms. To overcome<br />

these constraints, there is growing interest in the use<br />

of alternative radioisotopes such as yttrium-90 ( 90 Y)<br />

or alpha particle emitters, which might<br />

allow treatment to be delivered safely<br />

on an outpatient basis.<br />

Designer radiopharmaceuticals<br />

Recent advances have focused on<br />

designer molecules, selected to recognise<br />

and specifically target tumour cells. For<br />

S<br />

example, several bone-seeking<br />

radiopharmaceuticals are now available<br />

to treat metastatic skeletal pain.<br />

Although effective for symptom<br />

palliation, these treatments have not<br />

been shown to prolong survival or to<br />

have an anti-tumour effect. In a bid to<br />

improve outcome, we are participating in<br />

the first international, multicentre clinical<br />

trial using an isotope of radium ( 223 Ra).<br />

This is an alpha particle emitting<br />

radioisotope predicted to deliver a<br />

tumouricidal radiation dose to bone<br />

metastases. <strong>The</strong> clinical programme is<br />

supported by the development of new<br />

methods for image quantification and<br />

alpha particle dosimetry by the<br />

Radioisotope Physics Team in the <strong>Joint</strong> Department<br />

of Physics.<br />

Radiolabelled peptides – their use for the<br />

treatment of neuroendrocine tumours<br />

<strong>The</strong> <strong>Royal</strong> <strong>Marsden</strong> has extensive experience using 131 I<br />

meta iodobenzylguanidine ( 131 I mIBG) to treat refractory<br />

neuroendocrine tumours and is participating in a<br />

European study investigating the role of high activity<br />

mIBG therapy with chemotherapy in childhood<br />

neuroblastoma. However, only a minority of adult<br />

neuroendocrine tumours concentrate mIBG sufficiently<br />

well for this to be a realistic treatment option. By<br />

contrast, over 90% of neuroendocrine tumours overexpress<br />

surface receptors for a range of neuropeptides,<br />

such as somatostatin. Targeted therapy using<br />

radiolabelled peptides directed against somatostatin<br />

surface receptors (SSR) offers a new treatment approach<br />

for these tumours. Procedures were developed in <strong>2004</strong><br />

by <strong>Royal</strong> <strong>Marsden</strong> radiochemists to label SSR analogues<br />

with the isotope 90 Y. Over 100 patients have now been<br />

referred for 90 Y peptide therapy from the UK and<br />

abroad. An assessment programme has been<br />

established to monitor clinical outcomes, including<br />

quality of life assessment and will report later this year.<br />

Targeted therapy using<br />

radiolabelled peptides<br />

directed against<br />

somatostatin surface<br />

receptors offers a new<br />

treatment approach<br />

for neuroendocrine<br />

tumours.<br />

antibody conjugates directed against tumour cell surface<br />

antigens. <strong>The</strong> CD20 antigen, for example, is a useful<br />

target in B cell non-Hodgkin’s lymphoma (NHL). Building<br />

on previous experience using the anti-CD20 monoclonal<br />

antibody, rituximab, radio-labelled anti-CD20 antibodies<br />

have now been licensed to treat relapsed NHL. Low<br />

dose-rate radiation exploits the inherent radiosensitivity<br />

of haematological malignancies and acts synergistically<br />

with the biologically active antibody. Three patients with<br />

refractory NHL have now been treated using 90 Y<br />

labelled antibodies at the <strong>Royal</strong> <strong>Marsden</strong>.<br />

<strong>The</strong> Radioisotope Physics Team is developing<br />

methods for 90 Y quantification to enable prospective<br />

individual treatment planning. This approach will be<br />

critical to improving the efficacy of radioimmunotherapy<br />

and has wider implications for targeted radionuclide<br />

therapy in general.<br />

<strong>The</strong> future<br />

<strong>The</strong> unique availability of expertise in clinical PET,<br />

radionuclide therapy, radiochemistry and dosimetry<br />

physics at the <strong>Royal</strong> <strong>Marsden</strong> is encouraging research<br />

investment and partnership with industry. Future<br />

collaboration is planned that will bring together these<br />

aspects of current research interest. Further work is<br />

anticipated to develop targeted radionuclide dosimetry<br />

techniques for novel therapies with radiopharmaceuticals,<br />

using either PET/CT or single photon emission<br />

computed tomography (SPECT)/CT to improve the<br />

accuracy of these measurements.<br />

<strong>The</strong> main areas of future research interest for PET/CT<br />

are concerned with utilising alternative<br />

radiopharmaceuticals to measure different aspects of<br />

tumour metabolism.<br />

A new cyclotron and radiochemistry facility is being<br />

planned that will enable the production of novel<br />

radiopharmaceuticals that will be used in future<br />

research at the <strong>Royal</strong> <strong>Marsden</strong> and <strong>The</strong> Institute.<br />

Examples include:<br />

18 F-fluorothymidine to monitor increased DNA<br />

synthesis in tumours and changes in activity as a<br />

result of cytotoxic chemotherapy;<br />

18 F-fluorocholine to measure abnormal cell<br />

membrane metabolism in cancer, including<br />

prostate cancer;<br />

Radiopharmaceuticals designed to measure tumour<br />

hypoxia (low oxygen levels), a factor that is known<br />

to cause resistance to radiotherapy in a number of<br />

cancers. Knowledge of the distribution of hypoxia<br />

within a malignant tumour is likely to impact on the<br />

way radiotherapy is planned and we are currently<br />

collaborating in trials with Dr Chris Nutting and<br />

colleagues in the Head and Neck Unit to determine<br />

the impact of hypoxia imaging on intensity<br />

modulated radiotherapy in head and neck cancers<br />

with the goal of improving tumour control.<br />

new approaches are allowing a<br />

Ten years ago prostate cancer research at the <strong>Royal</strong><br />

<strong>Marsden</strong> and <strong>The</strong> Institute was in its infancy. Today there<br />

are coordinated, linked research teams working across a<br />

broad spectrum of areas. Our understanding of how the<br />

Why is prostate cancer<br />

different<br />

Prostate cancer poses a unique set of challenges for the<br />

laboratory scientist and clinician. As a result of prostate<br />

specific antigen (PSA) testing, prostate cancer has now<br />

become the most commonly diagnosed male cancer in the<br />

western world with over 27,000 cases recorded annually<br />

in the UK. It remains a major cause of mortality with<br />

nearly 10,000 cancer deaths per year. Yet, paradoxically<br />

most of the early prostate cancer now diagnosed by<br />

PSA testing may not need treating at all. <strong>The</strong> rate of<br />

progression is frequently so slow that the disease is of<br />

no threat – indeed autopsy studies show microfocal<br />

invasive disease in about 80% of 80-year-old men.<br />

<strong>The</strong>re is a pressing<br />

need to understand<br />

the processes that lead<br />

to disease progression<br />

in prostate cancer and<br />

to determine the<br />

effectiveness of local<br />

curative treatments<br />

and response to<br />

hormonal therapy.<br />

We also need to know much more about the<br />

events leading to androgen independence, metastases<br />

and death.<br />

How does a normal<br />

prostate develop<br />

Some of the molecular pathways that are deregulated in<br />

cancer cells are active during the development of the<br />

organ during fetal and neonatal life, but are normally<br />

switched off or are highly regulated in the adult.<br />

<strong>The</strong>refore, understanding how the prostate develops will<br />

provide insight into the pathways that are important in<br />

prostate cancer.<br />

In the Section of Gene Function and Regulation, the<br />

Sexual Development Team is studying the process of<br />

early prostate development, which is induced by the<br />

action of androgens, produced by the testis, on the<br />

urogenital sinus. We have identified genes that are<br />

specifically expressed in the newly formed prostatic<br />

epithelial buds (Figure 1) and are studying the function<br />

of these genes in this process. Through our links with<br />

Professor Colin Cooper (Section of Molecular<br />

Carcinogenesis) we are also investigating if these genes<br />

can serve as clinical markers for different stages of<br />

prostate cancer using tissue microarray (see below).<br />

What are some of the causes<br />

of prostate cancer<br />

Cancer arises from a change in the balance between<br />

cell self-renewal and differentiation. Many organs,<br />

including the prostate, contain a small population of<br />

cells, called stem cells, which have the unique ability to<br />

differentiate into the different cell types that make up a<br />

functional organ and are also capable of self-renewal.<br />

Changes in the properties of these cells are thought to<br />

drive the proliferation and survival of the cancer cell.<br />

David Hudson (Section of Molecular Carcinogenesis)<br />

is working to identify and characterise stem cells of the<br />

human prostate to understand how proliferation and<br />

differentiation are regulated in these cells. One goal of<br />

this work is to identify stem cell specific markers and<br />

investigate if they are aberrantly expressed in prostate<br />

cancer and may provide suitable targets for<br />

differentiation-based tumour therapy.

As many as 70% of the cancers diagnosed by PSA<br />

testing and then trans-rectal ultrasound guided biopsy<br />

may never lead to clinically important disease. This is<br />

central to the dilemma about the value of PSA screening<br />

for prostate cancer diagnosis. <strong>The</strong> standard clinical and<br />

histological characteristics of these cancers are unable<br />

to accurately predict outcome in the majority of cases.<br />

Our research programmes are targeting this critical area<br />

in several complementary ways. Molecular pathology<br />

techniques have huge potential to exploit the mapping<br />

of the human genome and unravel the complexity of<br />

genetic modifications that underlie the development of<br />

clinically significant cancer.<br />

Tissue microarrays can be used to study and<br />

evaluate the significance of large numbers of<br />

immunocytochemical markers. Professor Colin<br />

Cooper and his team have developed new<br />

techniques to preserve tissue for DNA and RNA<br />

analysis (Figure 2) at the time of radical<br />

prostatectomy (ie when a prostate gland is<br />

removed). This also allows for the production of<br />

tissue microarrays, which in turn means that many<br />

different types of investigations can be carried out<br />

subsequently from the very small amount of starting<br />

material now routinely taken during a prostate<br />

biopsy. We have already shown that new gene<br />

products E2F3 and HOX B13 are associated with a<br />

poor clinical outcome. In the future, large numbers<br />

of potential markers will be screened using our new<br />

microarray technology.<br />

<strong>The</strong>se studies closely link with the active surveillance<br />

research projects led by Chris Parker (Section of<br />

Radiotherapy), which offer very detailed biochemical<br />

(PSA), clinical and biopsy follow up rather than<br />

immediate radical curative treatment for men with<br />

good prognosis primary prostate cancer.<br />

Approximately 100 men per year are being recruited<br />

to the programme and initial results suggest that the<br />

considerable majority of men may avoid the side<br />

effects of radical treatment. <strong>The</strong> associated tissue<br />

banks, consisting of serum, urine, peripheral blood<br />

lymphocytes and prostate biopsy samples will<br />

provide a unique resource for translational studies.<br />

New markers will be tested and correlated with the<br />

probability of cancer either remaining indolent and<br />

harmless or of developing into progressive disease.<br />

In parallel, imaging studies are exploring the role of<br />

magnetic resonance imaging (MRI) and spectroscopy<br />

(MRS) in identifying and characterising prostate<br />

cancers. <strong>The</strong> intention here is to develop noninvasive<br />

methods for predicting the aggressiveness<br />

of disease (see Figure 2).<br />

Improving efficacy and<br />

reducing side effects of<br />

treatment for localised disease<br />

Radical radiotherapy and prostatectomy are the<br />

established curative options for localised disease. <strong>The</strong><br />

Radiotherapy Departments's programme of research with<br />

the <strong>Joint</strong> Department of Physics has continued to develop<br />

improved radiotherapy methods and to take these<br />

forward into institutional and national clinical trials.<br />

Improvement in PSA control rates<br />

A pilot, randomised, radiation dose escalation study<br />

(64 Gy vs 74 Gy), using conformal radiotherapy<br />

techniques undertaken at the <strong>Royal</strong> <strong>Marsden</strong>/<strong>The</strong><br />

Institute has shown a 12% improvement in PSA control<br />

rates at 5 years and a reduction in rectal and bladder<br />

side effects using a small radiation safety margin, which<br />

is now possible through the development of methods to<br />

improve treatment accuracy. A national trial involving<br />

850 men has now been completed.<br />

shorten the overall treatment time from 7.5 to 4 weeks<br />

for early localised disease. Recent radiobiological studies<br />

suggest larger daily treatments may be a more effective<br />

treatment strategy, which would be more convenient<br />

for patients and make better use of resources. With<br />

Department of Health funding we have now taken this<br />

trial forward nationally with a comprehensive quality<br />

assurance programme to allow more widespread<br />

introduction of these advanced techniques.<br />

Brachytherapy<br />

Brachytherapy uses implantation of small radioactive<br />

iodine seeds into the prostate. This has become a very<br />

popular method of treatment in the USA with<br />

encouraging long-term results. A recent donation to<br />

Vincent Khoo (Department of Radiotherapy) from the<br />

Master Masons has facilitated the development of a<br />

new brachytherapy service at the <strong>Royal</strong> <strong>Marsden</strong>.<br />

Men within the South West Thames Cancer Network<br />

will now have full access to state of the art surveillance,<br />

radiotherapy and surgical options.<br />

Intensity modulated radiotherapy (IMRT)<br />

Intensity modulated radiotherapy (IMRT) methods<br />

shrink-wrap the radiation dose around the cancer,<br />

thereby substantially avoiding normal tissues and<br />

reducing side effects. IMRT techniques are currently<br />

being studied for pelvic lymph node irradiation and to<br />

metastases and resistance to treatment with standard<br />

hormonal therapy by androgen suppression. <strong>The</strong><br />

mechanism for this bone trophism (ie the prostate<br />

cancer heading towards bone) and the hormone<br />

refractory state are poorly understood. Recently<br />

analysed studies have evaluated the roles of<br />

bisphosphonate drugs, the anti-endothelin agent<br />

atrasentan and high dose (activity) bone-seeking<br />

isotope radiation treatment. Preliminary results suggest<br />

benefit for all three approaches and the challenge now<br />

is how to integrate these advances with chemotherapy<br />

and other targeted treatment approaches.<br />

A new Phase I drug development facility<br />

Drug development for hormone refractory disease has<br />

been significantly aided by the establishment of a new<br />

Phase I drug development team led by Johann de Bono<br />

(Section of Medicine) focusing on hormone refractory<br />

prostate cancer. Agents targeting angiogenesis (VEGFR,<br />

FGFR), epigenetics (demethylating agents and HDAC<br />

inhibitors), cell signalling pathways (erbB, IGF-1R, mTOR)<br />

and the androgen receptor (HDAC/HSP-90 inhibitors)<br />

have been studied. Of particular importance, further trials<br />

are now underway using abiraterone acetate (developed<br />

by chemists at <strong>The</strong> Institute), which inhibits androgen<br />

synthesis by blocking 17 alpha-hydroxylase.<br />

Matched pairs of human prostate<br />

cancer tissue<br />

A critical issue as prostate cancer progresses from the<br />

hormone sensitive to hormone resistant state is to<br />

obtain matched pairs of human prostate cancer tissue<br />

so as to identify the underlying molecular mechanisms<br />

of disease progression and potential new targets for<br />

treatment. A new programme has been successfully<br />

funded and launched.<br />

Surrogate end-points<br />

Clinical studies that evaluate circulating tumour cells as<br />

a surrogate endpoint in clinical trials have started and in<br />

the future may be developed as an in vivo readout of the<br />

effectiveness of novel agents on their specific targets.<br />

DNA cancer vaccine<br />

A new initiative established by the National<br />

Cancer <strong>Research</strong> Institute South of England Prostate<br />

Cancer Collaborative (sited in the Male Urological<br />

Cancer <strong>Research</strong> Centre) is assessing the immunological<br />

effects of a new DNA cancer vaccine directed against<br />

the prostate specific membrane antigen with colleagues<br />

at Southampton University, who have successfully<br />

generated this novel plasmid vector. <strong>The</strong> first patient<br />

has been treated within 3 years of the initial laboratory<br />

development – an excellent example of the types of<br />

achievement we can expect from the Prostate Cancer<br />

Collaborative effort in the future.<br />

<strong>The</strong> future – building<br />

a foundation for<br />

translational research<br />

Our laboratory and clinical programmes will help<br />

unravel the molecular mechanisms involved in the<br />

progression of prostate cancer from a harmless<br />

bystander into an aggressive metastatic malignancy<br />

refractory to hormonal control. Tissue collections taken<br />

in steps along this pathway may identify new targets<br />

and suggest novel strategies designed to slow<br />

progression of disease either using specifically designed<br />

new molecules or dietary/environmental interactions.<br />

Every man's prostate<br />

cancer is different.<br />

Our goal is to translate<br />

the molecular<br />

characterisation of<br />

an individual's cancer<br />

into strategies aimed<br />

at containing or<br />

eradicating the disease<br />

in ways that will<br />

produce maximal<br />

benefit while reducing<br />

treatment side effects<br />

to a minimum.<br />

Genetic epidemiology: a tool for<br />

In addition to investigating whether or not a certain<br />

if the effect of an exposure is different in specific types<br />

of individual who differ in their genetic susceptibility<br />

Epidemiology and<br />

risk factors<br />

Epidemiologists seek to identify factors that alter the<br />

risk of cancer in humans, so that if the factors are<br />

causal they can be diminished, and if they are<br />

preventative they can be increased. For example, by far<br />

the largest change in cancer mortality in Britain during<br />

the last century as a consequence of scientific research<br />

was the decrease in lung cancer mortality that occurred<br />

during the second half of the last century. This followed<br />

from epidemiological studies that showed that the<br />

major cause of lung cancer is tobacco smoking, and<br />

that if smoking is stopped (or better if it is never<br />

started) risk decreases greatly.<br />

Frequency and mortality<br />

<strong>The</strong> methods used 50 years ago to show the association<br />

of tobacco smoking and lung cancer are the ones still in<br />

use by the epidemiologists of today who seek to find<br />

the causes of other cancers.<br />

First, studies were conducted that compared the<br />

frequency of smoking in lung cancer patients with<br />

that in people who did not have lung cancer, and<br />

it was found that the former smoked more than<br />

the latter.<br />

Secondly, comparisons were made between lung<br />

cancer mortality in people who smoked and in those<br />

who did not smoke. It was found that smokers died<br />

more often from lung cancer than did non-smokers.<br />

Because these observations were made in free-living<br />

humans who differed in many other respects as well as<br />

in their smoking habits, the conduct, design and<br />

interpretation of the studies were not quite as<br />

straightforward as the simplified description above<br />

might suggest. Nevertheless, if such observations are<br />

carefully carried out, are suitably analysed and are<br />

judiciously interpreted, they provide a surprisingly potent<br />

way of finding preventable causes of cancer. <strong>The</strong> use of<br />

similar methods has shown, for example, that asbestos<br />

inhalation is an important cause of respiratory cancers;<br />

that working in the manufacture of certain dyestuffs<br />

causes bladder cancer; and that exposure to ionising<br />

radiation can cause a large range of malignancies.<br />

Genetics and epidemiology<br />

<strong>The</strong> recent burgeoning of the science of genetics has<br />

added another weapon to the armoury for<br />

epidemiological investigation. It is now becoming<br />

possible not just to investigate whether a particular<br />

environment or behaviour causes a particular type of<br />

cancer in people in general, but also to find out the<br />

effects of an exposure, perhaps very different, in specific<br />

types of individual who differ in their genetic<br />

susceptibility to cancer. This is important because cancer<br />

is a disease of genetic damage, and it is likely that the<br />

causes of each type of cancer are a mixture of genetic,<br />

environmental and behavioural factors, which interact<br />

with each other. Hence, the way in which the<br />

environment and behaviours affect cancer risks may<br />

differ according to a person’s genetic constitution.<br />

Conversely, whether or not a person’s genetic<br />

constitution leads them to develop cancer is likely to<br />

depend on how they behave and on their environment.<br />

Understanding these interactions brings the prospect<br />

of a much more personalised and accurate picture of<br />

individual cancer risks, and of the actions that might<br />

be taken to diminish them.


It is likely that the<br />

causes of each type<br />

of cancer are a<br />

mixture of genetic,<br />

environmental and<br />

behavioural factors,<br />

which interact with<br />

each other. Hence,<br />

the way in which the<br />

environment and<br />

behaviours affect<br />

cancer risks may differ<br />

according to a person’s<br />

genetic constitution.<br />

Ultraviolet radiation, genetics and<br />

skin cancer<br />

An illustration from a genetic variable that can be<br />

assessed easily by anyone in everyday life, without<br />

needing genetic testing, shows the strong potential<br />

of this approach to finding cancer causation.<br />

<strong>The</strong> risk of skin cancer is greatly dependent on<br />

the extent of exposure to an environmental factor, the<br />

ultraviolet (UV) radiation in sunshine. <strong>The</strong> risk also<br />

depends heavily, however, on an individual’s genotype<br />

(ie their specific genetic makeup). People whose<br />

genotype gives them a dark skin will be at much lower<br />

risk of skin cancer, for the same amount of UV<br />

exposure, than will those who have paler skins. <strong>The</strong><br />

process of natural selection did not make northern<br />

Europeans well suited to live with tropical levels of UV<br />

radiation. Thus, causation and prevention depend not<br />

solely on environment, or behaviour, or genetics, but<br />

on the combination of these. <strong>The</strong> risk of skin cancer is<br />

relatively low for a person of dark skin genotype who<br />

lives in the high UV tropics, as it is for a genetically high<br />

molecular genetics. Two studies, one recently completed<br />

and the other just started, give some picture of the<br />

types of investigation in which we are now engaging<br />

to address these issues.<br />

risk Celtic redhead who lives in a temperate country.<br />

<strong>The</strong> Celt who sunbathes on the beach in Queensland,<br />

Australia, however, should not be so sanguine and the<br />

use of targeted prevention measures, such as protective<br />

sunscreens, is obvious.<br />

Most genetic risk factors for cancers are not<br />

outwardly perceptible, however, and therefore to<br />

ascertain them requires genetic testing in the laboratory.<br />

Such testing is now becoming practical on a large scale,<br />

so that the opportunities for studies of epidemiology<br />

and genetics in combination are opening up rapidly.<br />

Studies of cancer causation<br />

that combine epidemiology<br />

and molecular genetics<br />

<strong>The</strong> Institute’s Section of Epidemiology, in collaboration<br />

with the Section of Cancer Genetics and with the<br />

Breakthrough Toby Robins Breast Cancer <strong>Research</strong><br />

Centre, is setting up large-scale epidemiological studies<br />

of cancer causation that combine epidemiology and<br />

Causes of brain tumours<br />

Brain tumours are a fairly common type of cancer, and<br />

the most frequent of them, gliomas, are often rapidly<br />

fatal. We know very little of their causation or how to<br />

prevent them. <strong>The</strong> only known non-genetic cause is<br />

exposure to ionising radiation (eg X-rays), which<br />

accounts for very few cases. <strong>The</strong>re is anxiety among<br />

some members of the public, however, that radiofrequency<br />

radiation from mobile phone use might be<br />

a cause.<br />

We are investigating the causes of brain tumours<br />

using a study design called a case-control study. This<br />

compares exposures, behaviours and genes between<br />

patients who have brain tumours (cases) and people<br />

who do not have this condition (controls). We have<br />

collected data over the past 4 years from over 1,000<br />

brain tumour patients, plus control patients, to search<br />

for environmental and genetic causal factors. We are<br />

now analysing the data that have been collected, both<br />

within our own study and in combination with data<br />

from other similar studies from other countries (in<br />

order to gather even larger numbers).<br />

Causes of breast cancer<br />

<strong>The</strong> second example is a study approaching the problem<br />

of cancer causation in a different way: starting with<br />

people who have different levels of exposure to<br />

potential causes and then following their subsequent<br />

risks of breast cancer over time. This study, the<br />

Breakthrough Generations study, is recruiting more<br />

than 100,000 women to investigate, over time, whether<br />

those who have greater levels of particular factors<br />

(eg more exercise or greater radiation exposure) have<br />

greater (or lower) risk of breast cancer than those with<br />

less or none of these factors, and how this interacts<br />

with their genetic predisposition. <strong>The</strong> study was publicly<br />

launched in September <strong>2004</strong> and is progressing very<br />

encouragingly. Over 10,000 women contacted us by<br />

email or telephone in the first 24 hours after the launch<br />

to express interest in joining.


HEALTH RESEARCH<br />

<strong>The</strong> Breakthrough<br />

Generations study<br />

of the causes of breast<br />

cancer is planned to<br />

continue for 40 years<br />

or more, producing<br />

new results over that<br />

period.<strong>The</strong> Section of<br />

Epidemiology plans to<br />

start further large-scale<br />

studies of genetic<br />

epidemiology of<br />

various cancers over<br />

the next few years.<br />

<strong>The</strong> future<br />

Studies that combine epidemiology with molecular<br />

genetics offer enormous potential to find the causes<br />

of cancer. Such studies, however, can take a very long<br />

time. <strong>The</strong>y are also large, and as a consequence they<br />

are expensive.<br />

Hence, one of the key differences between the<br />

work of the Section of Epidemiology and that in many<br />

other parts of <strong>The</strong> Institute is the time-frame in which<br />

the studies are conducted. We are now analysing<br />

studies that we have been conducting for more than<br />

20 years, and we have other studies ongoing that<br />

will continue for 40 years or longer.<br />

In addition, the large number of subjects who<br />

need to be included in such studies and the large<br />

volume of data and blood samples that need to be<br />

processed and stored, means that studies of this type<br />

require considerable staffing, space and logistic support.<br />

An appreciable part of <strong>The</strong> Institute’s new Genetic<br />

Epidemiology Building will therefore be taken up with<br />

handling and storage of materials from these studies.<br />

We are greatly looking forward to moving into the new<br />

facilities built to accommodate this expanding activity.<br />

Dietary<br />

Lymphoedema, diet and body weight<br />

in breast cancer patients<br />

As the rates of success in the treatment of cancer improve,<br />

the need to examine the side effects of treatment and the<br />

quality of life of patients will increase. Dietary interventions<br />

may represent an important approach to the management<br />

of the unwanted effects of successful cancer treatment<br />

Nutrition and dietetics<br />

<strong>The</strong> Department of Nutrition and Dietetics is based in<br />

the Rehabilitation Unit at the <strong>Royal</strong> <strong>Marsden</strong>. <strong>The</strong><br />

Department provides a service in the hospital that<br />

routinely encompasses the following:<br />

liaison with catering about the appropriate provision<br />

of food service within the hospital;<br />

providing advice to patients and carers relating to<br />

food intake, specialised artificial nutrition and other<br />

dietary issues such as nutritional supplements;<br />

producing written information on diet and cancer<br />

and attempting to base this advice on up-to-date<br />

research evidence.<br />

Areas of recent research work in the Department<br />

have been to examine dietary interventions for<br />

managing treatment side-effects in patients and to<br />

compare the benefits of different energy supplements<br />

in counteracting weight-loss in cancer patients.<br />

Randomised controlled<br />

studies to examine the<br />

relationship between<br />

lymphoedema, diet and<br />

breast cancer<br />

Lymphoedema, a swelling of the arm, is a potential<br />

side-effect of surgical and radiotherapy treatment for<br />

breast cancer. A small number of studies and reports,<br />

dating back over the last 60 years, have made<br />

reference to the potential effect of diet and body<br />

weight on the aetiology and possible management of<br />

lymphoedema. Specifically, references in the literature<br />

do exist about the potentially beneficial influence of<br />

weight reduction and low fat diets on arm swelling.<br />

However, there have been no randomised controlled<br />

trials to test this hypothesis.<br />

Previously published research reports have<br />

highlighted the possibility that dietary changes may<br />

have a negative impact on a patient’s disease state<br />

and its prognosis.<br />

<strong>The</strong>re have also been studies to assess the dietary<br />

compliance of patients following a particular dietary<br />

regimen. However, there have not been intervention<br />

studies to examine the effectiveness of dietary<br />

intervention in women with lymphoedema after<br />

treatment for breast cancer. Randomised controlled<br />

studies are needed to examine the relationship<br />

between lymphoedema, diet and breast cancer.<br />

Nutrition, lifestyle and the risk<br />

of developing breast cancer<br />

<strong>The</strong>re are a number of established links between a<br />

person’s nutrition lifestyle and the risk of developing<br />

breast cancer. In postmenopausal women, obesity or<br />

increased body weight has been associated with an<br />

increased risk for the development of breast cancer.<br />

Increased body weight in postmenopausal women<br />

probably acts via an enhanced conversion of the steroid<br />

hormone precursor androstendione to oestrogens in<br />

adipose tissue. Women have a tendency to gain weight<br />

if they are being treated for cancer, and higher body<br />

weight has been shown in some studies to confer a<br />

poorer disease prognosis. <strong>The</strong>re also appears to be<br />

a positive linear association between height and the


elative risk of developing breast cancer. This association<br />

appears to be due to the growth promotional effects<br />

of nutrition during early life, and the age of menarche<br />

(ie the age at which menstruation commences).<br />

<strong>The</strong> causes of lymphoedema<br />

<strong>The</strong> development of lymphoedema in women who have<br />

undergone treatment for breast cancer depends on a<br />

number of factors, including the extent of surgery and<br />

radiotherapy to the axilla (ie the underarm area). <strong>The</strong>re<br />

are a number of published reports suggesting that obesity<br />

predisposes to the development of lymphoedema. Some<br />

proposed mechanisms to explain this have included:<br />

fat necrosis with secondary infection, regional<br />

axillary lymphangitis (ie infection of the lymph<br />

channels) with sclerosis (ie a thickening of tissue due<br />

to a pathological process) and vessel obstruction;<br />

obesity causing enlargement of the upper arm<br />

thereby reducing the support provided by the skin;<br />

the muscle pump for advancing the lymph in the<br />

lymphatics is less efficient within the flabby tissues;<br />

delayed wound healing in obese patients.<br />

Lymphoedema in<br />

women who have<br />

undergone treatment<br />

for breast cancer has<br />

been shown to have a<br />

negative psychological<br />

impact and contributes<br />

to a lower quality of life.<br />

How diet may help in the<br />

management of lymphoedema<br />

Diet may help in the management of lymphoedema<br />

via the following mechanisms:<br />

a reduction in the number of adipocytes (fat cells)<br />

that would otherwise contribute to the swelling<br />

of the affected limb;<br />

a reduction in the size of adipocytes may have a<br />

beneficial effect on the arm;<br />

a reduction of fat under the arm (in the axilla)<br />

may improve lymph drainage through this area.<br />

Dietary intervention<br />

and lymphoedema<br />

<strong>The</strong> Department’s interest in the potential influence<br />

of diet on the treatment of lymphoedema has<br />

developed jointly with the Lymphoedema Service<br />

in the Rehabilitation Unit at the <strong>Royal</strong> <strong>Marsden</strong>.<br />

Previously published reports indicated that a low<br />

fat diet might be of benefit to patients suffering from<br />

lymphoedema of the arm. Here, the suggestion was<br />

that low fat diets would encourage the mobilisation<br />

of subcutaneous fat. However, it was not clear whether<br />

this was independent of any general weight reduction<br />

in the patients. A number of our own patients were<br />

requesting dietary advice to lose weight, and in some<br />

individuals there appeared to have been a certain<br />

amount of benefit in terms of weight loss and the<br />

management of the patients’ lymphoedema.<br />

Control group<br />

<strong>The</strong>refore, we decided to investigate the possible<br />

relationship between diet and lymphoedema in a more<br />

systematic way to establish what benefit, if any, might<br />

be achieved for patients with lymphoedema. Two<br />

research studies were undertaken by the Department of<br />

Nutrition and Dietetics in conjunction with the<br />

Lymphoedema Service.<br />

<strong>The</strong> first study showed that there was no<br />

significant beneficial effect of a low fat diet in women<br />

with lymphoedema, following treatment for breast<br />

cancer, that were undergoing the usual procedure for<br />

management of their lymphoedema. It appears<br />

unlikely that a low fat diet alone has any effect<br />

on the management of lymphoedema.<br />

Interestingly, analysis<br />

of the data has shown<br />

a significant correlation<br />

between weight loss<br />

and a reduction in<br />

lymphoedematous<br />

arm volume.<br />

Intervention study of weight<br />

reduction in women with<br />

lymphoedema following<br />

treatment for breast cancer<br />

A second intervention study focused on examining<br />

whether weight reduction alone would influence the<br />

management of lymphoedema following treatment for<br />

breast cancer. <strong>The</strong> primary endpoint of the study was to<br />

measure excess arm volume in the lymphoedematous<br />

limb. Accordingly, limb volume measurements were taken<br />

during the study (either manually, with a tape measure,<br />

or using a perometer) and were compared with the same<br />

limb at the beginning of the study. During the study we<br />

focussed particularly on enhancing dietary compliance,<br />

using a shorter intervention period, and also including<br />

secondary endpoints that related to body image, selfesteem<br />

and function.<br />

It is important to note that for any dietary<br />

intervention study to be effective there needs to be<br />

compliance (ie patients need to stick to what they have<br />

been asked to do) with the dietary regimen. Measuring<br />

dietary compliance is often difficult, with a dietary diary<br />

often being the main measure of food intake. Use of a<br />

weighed food intake provides the most accurate data, but<br />

this is difficult to carry out during the course of normal<br />

daily life, and so may impinge on dietary intake. Other<br />

methods are less accurate in their assessment of the size<br />

of food portions, but are nevertheless easier to undertake.


HEALTH RESEARCH<br />

Accordingly, in our randomised study, a photographic<br />

representation of food portions was used to help<br />

subjects record their intake. Food intake was assessed<br />

by completion of three 7-day diaries, prior to, and<br />

during, the 24-week study and by 24-hour recalls at<br />

hospital visits. <strong>The</strong>se dietary records were analysed for<br />

nutritional content using a computer programme.<br />

Calculated energy intakes were compared with<br />

calculated multiples of basal metabolic rate, in order<br />

to assess whether the records were a true reflection<br />

of energy intake in normal circumstances. Patients<br />

were randomly allocated to two dietary groups:<br />

a control group receiving no dietary advice; a group<br />

on a weight reduction diet. Both groups underwent the<br />

usual limb compression treatment (hosiery or bandages)<br />

for the management of their lymphoedema.<br />

At the end of the 12-week intervention period, the<br />

weight reduction group had a statistically significant<br />

reduction in weight compared to the control group.<br />

<strong>The</strong> weight reduction<br />

group showed a<br />

statistically significant<br />

reduction in the<br />

percentage of excess<br />

arm volume during<br />

the intervention period,<br />

with the mean excess<br />

arm volume changing<br />

from 24% to 15%<br />

when compared with<br />

the control group<br />

(Figure 2).<br />

<strong>The</strong> future<br />

As the success in treating cancer improves, the need<br />

to examine the side effects of treatment and quality<br />

of life issues for patients will increase. Although dietary<br />

interventions may be beneficial for managing the<br />

untoward consequences of treatment, we will need to<br />

be sure that they are not detrimental in terms of<br />

disease progression and long-term patient survival.<br />

<strong>Research</strong> into the best<br />

treatment options for<br />

patients is obviously<br />

essential. Increasingly,<br />

however, other aspects<br />

of patient care may<br />

also have an important<br />

role to play in the daily<br />

lives of patients who<br />

have successfully<br />

completed treatment<br />

and are now learning<br />

to live with cancer.<br />
