CATALYST FOR<br />
THE GOOD AND BAD<br />
In popular fiction, the typical plot often would<br />
portray heroes with unique abilities who<br />
can inflict a crippling blow to the antagonist.<br />
Wishfully, this thought may cross the mind if only<br />
the battle against cancer is this straightforward.<br />
Indeed, working hard to make this wish come true is what Prof Kanaga Sabapathy<br />
is doing in his approach to advancing the treatment outcomes for cancer.<br />
The Principal Investigator from the Laboratory of Carcinogenesis at NCCS is<br />
studying the origins of cancer and how it develops by understanding the basic<br />
cellular mechanisms. He then introduces suitable ‘heroes’, or catalysts, to save the<br />
ailing cells.<br />
For the record, he has made inroads in his study on cancer-related proteins and how<br />
they have been responsible for promoting tumour cell growth. One of the main focus<br />
of his research is studying the master tumour suppressor protein p53, and its related<br />
form p73, to shed further light on their traits and how they can be modulated for<br />
better or for worst.<br />
Essentially, p73 exists in two forms - TAp73 which has tumoursuppressing<br />
properties like the p53; and DNp73 which has<br />
oncogenic properties and promotes growth of cancer cells<br />
(opposite to TAp73), by inhibiting p53 and TAp73.<br />
“One could not hope for a better<br />
mentor than Prof Sabapathy.<br />
His enthusiasm and passion<br />
for research can be quite<br />
contagious...”<br />
Mr Iqbal Dullo<br />
In his study which was documented ‘The anti-apoptotic Delta Np73 is degraded in<br />
a c-Jun-dependent manner upon genotoxic stress through the antizyme-mediated<br />
pathway’ in the Proceedings of the <strong>National</strong> Academy of Science of the United States<br />
of America (PNAS), Prof Sabapathy discovered that genotoxic insult such as exposure<br />
to chemotherapeutic drug doxorubicin, which stabilises and activates TAp73, is also<br />
able to reduce the levels of tumour-promoting DNp73 in cancer cells. Together with<br />
his team, they probed into how DNp73 levels are regulated under this scenario so as<br />
to better understand the mechanisms which can subsequently be utilised to modulate<br />
its expression in cancer cells.

They discovered that c-Jun, a protein that<br />
is typically induced by a variety of stress<br />
signals was a key player. Further testing<br />
provided strong evidence that c-Jun was<br />
indeed capable of inducing the degradation<br />
of DNp73 via the non-classical polyamineantizyme<br />
pathway, an outcome that was<br />
needed to reduce the proliferation and<br />
survival of cancerous cells.<br />
These findings gave a new and unexpected<br />
insight into why cancers, which have high<br />
levels of DNp73, are resistant to some<br />
chemotherapy regimes.<br />
Prof Sabapathy explained that it all boils<br />
down to knowing the abilities of cancer<br />
cells. “We seek to understand why<br />
cancer cells behave the way they do,<br />
how they work in order to know how to<br />
deal with them. We can then work with<br />
our translational research counterparts<br />
to determine how to treat them, whether<br />
it is through drug development or other<br />
treatment forms.”<br />
Although the discovery brings plenty of<br />
hope for cancer patients and research,<br />
Prof Sabapathy explained that there is still<br />
more to be done. “We will now test for<br />
compounds which will inevitably kill cancer<br />
cells through the regulation of DNp73,<br />
whether they are toxic and bring harm to<br />
normal cells. The findings will be useful to<br />
identifying bases to develop drugs.”<br />
To ensure that no efforts are spared,<br />
the team will have a strenuous task of<br />
testing hundreds of compounds each<br />
time. Although the work may be likened<br />
to looking for a needle in a haystack,<br />
Prof Sabapathy believes that it adds<br />
to the value chain for patients. “Our<br />
work is important for pharmaceutical<br />
companies as it helps them in the<br />
development of new drugs,” he said.<br />
As a sweetener to his work, research<br />
funds are ample, though they come at no<br />
small cost. Over the years, Prof Sabapathy<br />
has been constantly soliciting for research<br />
funds through publishing scientific papers<br />
and presenting notable research work.<br />
To date, he has published more than 50<br />
papers and the influence that comes from<br />
them helps him to secure research grants.<br />
“When a scientist publishes a paper,<br />
recognition will come when the paper<br />
contains good information for the field.<br />
Our productivity also hinges on how<br />
many papers we have published and how<br />
impactful they are.”<br />
As part of his work at NCCS, Prof<br />
Sabapathy has been mentoring a team<br />
of PhD and Masters students who are<br />
also research officers, such as Mr Iqbal<br />
Dulloo who has been working on the<br />
DNp73 project. Commenting on the<br />
calibre of his mentees, he said that their<br />
stint at NCCS has put them in good<br />
stead. “It is about sharing my knowledge<br />
and experience and guiding them.<br />
Although the standard between the PhD<br />
and Masters Students vary somewhat, I<br />
believe they are equally capable. I am<br />
also confident that the PhD students will<br />
endure in the field, even if they work in<br />
the West.”<br />
Mr Dulloo has benefited much from<br />
Prof Sabapathy’s guidance. He said:<br />
“One could not hope for a better mentor<br />
than Prof Sabapathy. His enthusiasm<br />
and passion for research can be quite<br />
contagious. His guidance and openness<br />
to discussion had undoubtedly helped<br />
me get the most out of my years in<br />
the lab as well as my PhD study. The<br />
knowledge, training and scientific<br />
achievements that I have made under<br />
his mentorship are the perfect building<br />
blocks for a career in the ever-so<br />
competitive world of medical research.”<br />
Prof Sabapathy works with a multinational<br />
team, which he considers “a<br />
challenging yet rewarding experience for<br />
the team as they also gain cultural insights<br />
which will be valuable when they work in<br />
the US or Europe.“<br />
With so much on his plate, it is little<br />
wonder that the father of a teenage son<br />
values the little family time he gets. He<br />
interacts with his 14-year-old during<br />
morning drives to school, going for short<br />
walks together when time permits and<br />
annual vacations.<br />
Hence, Prof Sabapathy<br />
has no regrets in<br />
taking this arduous<br />
and rugged route.<br />
“I have not had<br />
second thoughts<br />
about what I have<br />
done so far. I love<br />
Science and knew<br />
that there is nothing<br />
else I would do apart<br />
from research.”<br />

LOOKING AHEAD…<br />
<strong>Cancer</strong> Opens My Eyes to the Beauty Around Me<br />
To be diagnosed with breast cancer at a young age is never<br />
easy to accept. It’s even more difficult when life until then has<br />
been plain sailing. Even so, when the news broke, like a bolt<br />
out of the blue, Ms Yvonne Boon accepted her fate bravely.<br />
She cast a positive look on the future, to survive.<br />
At age 35, Yvonne had a life that every woman wished for, namely, a loving<br />
husband, career satisfaction and three intelligent, beautiful young children.<br />
She led a fulfilling life as an active volunteer in church and spend her<br />
weekends and evenings indulging in her favourite activities like doing sports and<br />
having meals with her family.<br />
When diagnosed with her illness, the obvious came to mind: the end of life was<br />
near. She remembered her sister who succumbed to breast cancer because she failed<br />
to receive treatment. But it was different for her. She could count on her immediate<br />
family to give her the support she needed. She had her husband and three children<br />
to live for. Before long, Yvonne came to terms with her condition. She decided not<br />
to let cancer take her life away.<br />
She told herself that she had to be strong. She went through a lumpectomy and<br />
eventually mastectomy, chemotherapy and hormonal therapy. These took more than<br />
a year to complete. “It is amazing to be alive!” she gushed. “When I was healthy in<br />
the past, I took so much for granted. I used to push myself to multi-task too much,<br />
not listening to my body when I was tired. I think I’m very blessed as I have support<br />
from my husband, family and friends and I was also well covered by insurance.”<br />
For Yvonne, survival began at the point of diagnosis. It was the time when cancer<br />
patients are forced to confront their own mortality and begin to make adjustments<br />
that will be part of their immediate and long term future. “My plight opened my<br />
eyes to more important things, like family and friends. Work and material things<br />
just don’t matter as much any more and I am no longer petty about small issues.<br />
I have also become more understanding and generous towards others. I am also<br />
making changes to my priorities. Being diagnosed with cancer gives me a chance to<br />
do things better the second time round.”<br />
There were times when doubts crossed her mind and coping with them got tough.<br />
The side effects of treatment took a toll on her. “There were times when it seemed<br />
hard to move on and I wanted to give up. But when I look at my children, they<br />
reaffirmed my will to fight on and live for them. Whenever I fall into negative mode,<br />
I remind myself to look at all the positive things such as my children and my faith.”<br />
The experience has made her see life with a different purpose. “<strong>Cancer</strong> does not simply<br />
end at remission. Life will change in unexpected ways. Some have made their lives more<br />
meaningful, while others and their loved ones have responded negatively. As for me,<br />
finding meaning is one way to understand my cancer experience. It made me realise the<br />
greater purpose behind my illness and what it means for me and my family.”<br />
Part of her greater purpose was also to help others<br />
make sense of cancer. Yvonne explained, “The<br />
fear of death that permeates most people when<br />
they are diagnosed often leads me to think about<br />
what I will leave behind and what I would like<br />
to do with the time I have left. I want to make<br />
sure I do my best while I still have the strength.<br />
I want to teach my children to be independent,<br />
to be kind and loving towards one another. Most<br />
important, I want them to support one another<br />
should the day come when I am no longer<br />
around. I want to help as many as I can to make<br />
sense of their sickness, to embrace it and to live<br />
their lives as meaningful as possible.”<br />
On how she has made sense of<br />
the sickness herself, Yvonne has a<br />
refreshing perspective:<br />
“<strong>Cancer</strong> has been the most beautiful<br />
experience in my life. Initially there<br />
was a reason to survive, then a<br />
purpose in helping others. It has<br />
enriched my life and made me not<br />
take life for granted. I am a survivor<br />
and can now watch my children<br />
grow and help others learn to see<br />
the beauty of life.”
OVERCOMING RADIATION<br />
SIDE EFFECTS<br />
PAGE B1<br />
Looking Forward<br />
SALUBRIS<br />
May / June 2010<br />
Radiation treatment is painless though<br />
some undesirable side effects may occur<br />
over the course of treatment. Radiation<br />
side effects vary in types and severity,<br />
depending on the site of treatment, the<br />
duration of treatment and the amount of<br />
body tissues involved in the treatment<br />
volume. Most radiation side effects are<br />
specific to the areas being irradiated<br />
and they can be divided into short-term<br />
and long-term side effects. This article<br />
discusses some of the common, shortterm<br />
side effects and useful measures to<br />
delay/reduce the discomfort.<br />
SKIN<br />
Side effects on skin start with a darkened<br />
pigmentation (erythema), and later develop<br />
into dry and moist desquamation. Skin<br />
appears a pinkish colour and may be<br />
accompanied by a sensation of burning and<br />
itching. This usually occurs in the third week<br />
of treatment and progresses over the course<br />
of radiation treatment. It can develop into<br />
dry desquamation, which is presented with<br />
dryness, itching, scaling and flaking. A darker<br />
skin tone will also be noted. All these only<br />
occur within the treated skin. It is important<br />
to monitor the further development of the<br />
skin reaction into moist desquamation, which<br />
comes with burning, itching and tenderness. It<br />
occasionally brings about blister formation and<br />
pain. Appropriate dressing is required and it is<br />
essential to observe signs of infection such as<br />
fever, foul odour, purulent exudates, pain and<br />
swelling within and around the area.<br />
For head and neck treatment, besides<br />
erythema, hair in the facial area and<br />
particularly at the back of the head that is<br />
treated will gradually fall and become thin.<br />
For treatment to the pelvic region, pubic<br />
and abdominal hair will also gradually shed.<br />
The hair usually re-grows once radiation<br />
treatment ceases.<br />
Recommended skin care during radiation treatment:<br />
• For facial and underarm shaving, use an electric razor to prevent cuts.<br />
• Only apply lotion that is prescribed by your Radiation Oncologist. Avoid<br />
petroleum jelly-based products that are poorly absorbed and difficult to remove.<br />
• Avoid rubbing the affected skin. Apply lotion with clean hands.<br />
• Aloe vera gel may be used on intact skin. Once the skin is broken with scaling,<br />
flaking and peeling, discontinue use of aloe vera.<br />
• For head and neck treatment, avoid shirts with tight collars.<br />
• Protect affected skin area from direct sunlight and excessive wind exposure.<br />
• Avoid swimming in chlorinated pools or hot tubs. These have a drying effect on skin.<br />
• Do not apply cold or heat treatment directly on the affected skin to avoid<br />
thermal injury.<br />
• Do not use adhesive tapes on the affected skin such as medicated skin patch.<br />
If dressing is required, let the radiation oncology nurse perform the dressing.<br />
• Do not use products containing perfumes or additives, alcohol and alpha hydroxy<br />
acids (AHAs). For head and neck treatment, be cautious on the choice of aftershave<br />
lotion and keep make-up to the minimum. For breast treatment, avoid deodorants<br />
and alkaline-based soap.<br />
• Wash the affected area with lukewarm water and gently pat dry with a soft<br />
towel to avoid abrasion. If the head is treated, wash hair using lukewarm water<br />
and mild, non-medicated shampoo. Pay attention to skin folds. Keep this area<br />
clean, dry and cool.<br />
• Cornstarch, non-perfumed talc and baby powder may be used on intact skin.<br />
With moist desquamation, avoid these products as it promotes fungal and<br />
bacterial infection.<br />

OVERCOMING RADIATION<br />
SIDE EFFECTS<br />
Continued from page B1.<br />
THROAT AND MOUTH<br />
For treatment to the head and neck region, your radiation oncologist will minimise the<br />
radiation reaching areas not affected by the disease. Oral Cavity is protected if it is not an<br />
intended organ of treatment. The throat and oral cavity is lined by mucous membranes that<br />
react to radiation like skin. Mucositis can occur, showing ulcers in the throat and mouth.<br />
Treatment to whole or part of the oral cavity can impact salivary and mucus production,<br />
causing stickiness in the mouth. This will further lead to dry mouth and change in taste.<br />
To manage these side effects, you are advised to:<br />
• Take frequent small sip of drinks. Avoid carbonated and sweetened drinks.<br />
• Gargle using non-alcohol based mouth rinses to reduce the stickiness in the mouth.<br />
• Use cough suppressants, avoid smoking and limit alcohol consumption.<br />
• Take semi-solid foods if eating becomes painful. Avoid dry food, sticky rice and<br />
spicy food.<br />
• Consume liquid food supplements or meal replacement drinks. Have smaller<br />
portions but more frequent meals.<br />
• Consult your radiation oncologist should any discomfort arise.<br />
• Use toothbrushes with soft bristle to prevent gum injury and rinse mouth with a<br />
non-alcohol based mouthwash. Lastly, apply a layer of oral moisturiser on the<br />
inner lining of oral cavity. Continue oral care post-treatment and it is important to<br />
have regular visit to dentist. Tooth extraction following radiation to the mouth is<br />
not recommended.<br />
JOINT MOVEMENT<br />
Scarring can develop following breast<br />
surgery and/or radiation to the area<br />
under the upper arm. This can affect<br />
the suppleness of your joint movement<br />
resulting in stiffness in your upper arm<br />
movements. Daily exercise by lifting arm<br />
above head will reduce stiffness in the<br />
shoulder joint.<br />
GENERAL WELL-BEING<br />
AND APPETITE<br />
Patients undergoing radiation treatment<br />
may experience fatigue, poor appetite,<br />
nausea and occasional vomiting. These<br />
reactions may or may not be directly linked<br />
to radiation treatment and are possibly<br />
associated with emotional burden of the<br />
diagnosis and fear of the uncertainties<br />
related to treatment. Nausea and vomiting<br />
can be effectively treated with prescribed<br />
medication. Taking short naps throughout<br />
the day can boost your energy level.<br />
OESOPHAGUS, BOWEL, BLADDER AND RECTUM<br />
Mucositis can develop in the membranes of oesophagus, bowel, bladder and rectum,<br />
causing irritation and dysfunctions there. Radiation treatment to the chest region can affect<br />
swallowing, causing hoarseness of voice or infection of the oesophageal and tracheal lining.<br />
Radiation to the pelvis can cause lower abdominal discomfort and a burning sensation while<br />
passing urine. You will notice an increased frequency of urination, or bowel movement.<br />
To manage these side effects, you are advised to<br />
• Maintain hydration by taking frequent sips of water or other sources of fluids.<br />
• Regulate the consumption of fruits, dairy products and fibre to keep stools soft to<br />
prevent trauma or irritation during defecation.<br />
• Consult your radiation oncologist if you notice blood stains in sputum, urine or<br />
faeces, or when the side effects worsen, occurs frequently, and accompanied with<br />
vomiting or fever.<br />
• For female patients who undergo radiation treatment in the pelvis region, regular<br />
douching or washing of the vagina is recommended. This is to reduce the risk of<br />
infection and to avoid narrowing of the vagina. Your doctor can recommend the<br />
appropriate cleansing solution and device to use.<br />
CONCLUSION<br />
The radiation side effects<br />
presented above are<br />
generally short-term. These<br />
effects should not prevent<br />
you from working or<br />
performing your daily chores.<br />
However, a gradual reduction<br />
in physical activities mid-way<br />
through a course of radiation<br />
treatment and immediately<br />
after the completion of the<br />
treatment is advised.<br />

A WELLNESS PLAN<br />
AFTER CANCER<br />
PAGE B3<br />
Tender Care<br />
SALUBRIS<br />
May / June 2010<br />
After cancer treatment, many survivors want to find<br />
ways to reduce the chances of their cancer coming<br />
back. Some worry that the way they eat, the stress in<br />
their lives, or their exposure to chemicals may put<br />
them at risk. <strong>Cancer</strong> survivors also find that this is<br />
a time when they reflect on how they take care of<br />
themselves and their health. This is an important start<br />
to living a healthy life after cancer.<br />
EATING WELL AFTER<br />
CANCER TREATMENT<br />
1 Eat a variety of healthy foods.<br />
• Eat five or more servings of<br />
vegetables and fruits daily.<br />
• Choose whole grains rather<br />
than processed (refined) grains<br />
and sugars.<br />
• Choose foods that help you<br />
maintain a healthy weight.<br />
• Limit eating red meats, especially<br />
high fat or processed meats.<br />
2 Maintain a healthy weight. Keep your<br />
BMI at a healthy range of between<br />
18.5 – 22.9 (kg/m2).<br />
3 Limit alcoholic drinks. Research shows<br />
that drinking alcohol can increase your<br />
chances of developing certain cancers<br />
e.g. liver cancer, stomach cancer,<br />
oesophageal cancer.<br />
EXERCISE AFTER<br />
CANCER TREATMENT<br />
Everyone knows that exercise has many<br />
health benefits such as increasing<br />
your fitness level and helping you lose<br />
weight. One benefit of exercise that is<br />
often overlooked is that it improves your<br />
mood and give you a general feeling of<br />
well being.<br />
Some studies have been done to find<br />
out if physical activity affects survival<br />
after cancer treatment. Many researches<br />
have shown that moderate exercise<br />
(brisk walking, swimming, cycling) for<br />
about 30 minutes every or almost every<br />
day can:<br />
• Reduce anxiety and<br />
depression<br />
• Improve mood<br />
• Boost self-esteem<br />
• Reduce symptoms of fatigue,<br />
nausea, pain and diarrhoea<br />
It is important to start an exercise<br />
programme slowly and increase activity<br />
over time. Some survivors may need to<br />
take special care when exercising. Talk<br />
to your doctor before beginning any<br />
exercise programme.<br />
FOLLOW-UP CARE<br />
At the first follow-up visit, ask your<br />
doctor:<br />
• The tests and follow-up care<br />
you need, and how often you<br />
will need them.<br />
• The kinds of physical problems<br />
you may experience from the<br />
cancer treatment and what<br />
you can do to prevent, reduce<br />
or solve them.<br />
At each visit, tell your doctor about:<br />
• Symptoms that you think may<br />
be a sign of cancer returning.<br />
• Any pain that troubles you.<br />
• Any physical problems that get<br />
in the way of your daily life or<br />
that bothers you such as fatigue,<br />
trouble sleeping, unexplained<br />
weight gain or loss.<br />
• Other health problems you<br />
have such as heart disease,<br />
diabetes or arthritis.<br />

FACING FORWARD AFTER<br />
CANCER TREATMENT<br />
Just as cancer affects a person’s<br />
physical health, it affects the<br />
way one feels, thinks and acts.<br />
Besides having many emotions<br />
that may surprise the individual,<br />
the treatment may actually<br />
change the way the brain works.<br />
Just as the individual needs<br />
to take care of the body after<br />
treatment, the person needs to<br />
take care of his emotions.<br />
Each person’s experience with cancer is<br />
different and unique, and the feelings,<br />
emotions and fears that he has are unique<br />
as well. The values the individual grew up<br />
with may affect how he thinks about and<br />
deal with cancer. Some people may feel<br />
they have to be strong and protect their<br />
friends and families. Others seek support<br />
from loved ones or other cancer survivors<br />
or turn to their faith to help them cope.<br />
Some find help from counsellors and<br />
others outside the family, while others do<br />
not feel comfortable with this approach.<br />
Whatever the individual decides, it is<br />
important to do what’s right for him and<br />
not compare with others.<br />
FEAR THAT CANCER WILL<br />
COME BACK<br />
Worrying about the cancer recurring is<br />
normal, especially during the first year after<br />
treatment. This is one of the most common<br />
fears people have after cancer treatment.<br />
Even years after treatment, this fear may<br />
always be at the back of their minds. For<br />
some, the fear is so strong that they no<br />
longer enjoy life, sleep well, eat well, or<br />
even go for follow-up visits.<br />
“If I get it again, what am I going to do?”<br />
one woman said. “I never thought I’d make<br />
it through the first time.”<br />
Of course, not everyone reacts this way. As one survivor puts it,<br />
“<strong>Cancer</strong> is just part of life, and we always have hope.”<br />
As time goes by, many survivors report that their fear of cancer recurring lessens and they find<br />
themselves thinking less often about their cancer. However, even years after treatment, some<br />
events can cause the individual to become worried about his health.<br />
These may include:<br />
• Follow-up visits<br />
• Anniversary events (like the date of diagnosis or surgery or ended treatment)<br />
• Birthdays<br />
• Illness of a family member<br />
• Symptoms similar to the ones he had when cancer was found<br />
• The death of someone who had cancer<br />
• Personal reminders. For example, one man said he used to go to a particular dessert<br />
stall after every chemotherapy treatment because the sweet potato in ginger soup they<br />
serve was the only thing he could stand to eat. After treatment he had to stop going to<br />
the stall because it reminded him of treatment and made him “sick in the stomach”.<br />
Thinking and talking about the feelings can be hard. Some people just want to move on. They put<br />
the thought of cancer and all that goes with it out of their minds. While it is important not to let<br />
cancer “rule your life”, it may be hard to do.<br />
Work towards having a positive attitude. This means looking for what is good even in bad times<br />
and try to be hopeful instead of thinking the worst. Use positive energy to focus on wellness and<br />
do what you can to stay as healthy as possible.<br />

至 于 头 部 和 颈 项 治 疗 , 除 了 会 出 现 红 斑 外 , 脸 部 毛 发 也 会 渐 渐 脱 落 和 稀 疏 , 后 脑 勺 的 毛 发 的<br />
脱 落 一 般 更 是 特 别 严 重 。 此 外 , 骨 盆 部 位 、 腹 部 和 耻 部 的 毛 发 也 会 逐 渐 脱 落 。 但 放 射 治 疗 结<br />
束 后 , 这 些 毛 发 通 常 都 会 重 新 长 出 来 。<br />
放 射 治 疗 期 间 的 皮 肤 护 理 建 议 包 括 :<br />
• 使 用 电 动 剃 刀 剃 除 脸 部 和 腋 下 毛 发 , 以 免 刮 伤 。<br />
• 只 使 用 放 射 肿 瘤 科 医 生 指 定 的 润 肤 乳 。 避 免 使 用 吸 收 力 低 和 难 以 抹 掉 的 凡 士 林 产 品 。<br />
• 避 免 揉 搓 受 感 染 的 皮 肤 。 涂 抹 润 肤 乳 前 要 确 保 双 手 干 净 。<br />
• 完 好 的 皮 肤 可 使 用 芦 荟 凝 胶 。 一 旦 皮 肤 龟 裂 和 脱 落 , 务 必 停 止 使 用 芦 荟 护 肤 品 。<br />
• 至 于 头 部 和 颈 项 治 疗 , 避 免 穿 紧 领 的 衣 服 。<br />
• 避 免 阳 光 直 射 和 大 风 吹 到 受 感 染 的 皮 肤 。<br />
• 避 免 在 氯 化 泳 池 游 泳 或 浸 泡 在 浴 缸 内 , 以 免 皮 肤 变 得 干 燥 。<br />
• 不 要 在 受 感 染 皮 肤 上 直 接 使 用 冷 或 热 疗 法 , 以 免 灼 伤 皮 肤 。<br />
• 不 要 在 受 感 染 皮 肤 上 使 用 胶 带 , 例 如 药 用 贴 片 。 如 果 您 须 要 敷 药 , 应 让 放 射 肿 瘤 科 护 士 替 您<br />
进 行 。<br />
• 不 要 使 用 含 有 香 水 或 添 加 剂 、 酒 精 和 阿 尔 法 羟 基 酸 (AHA) 的 产 品 , 它 们 多 见 于 各 种 卫 浴 用<br />
品 。 至 于 头 部 和 颈 项 治 疗 , 小 心 选 择 须 后 水 和 减 少 使 用 化 妆 品 。 至 于 乳 房 治 疗 , 避 免 使 用 除<br />
臭 剂 和 碱 性 肥 皂 。<br />
• 用 温 水 清 洗 患 处 , 然 后 用 柔 软 的 毛 巾 轻 轻 拍 干 , 以 免 擦 伤 。 至 于 头 部 治 疗 , 用 温 水 及 温 和 的 非<br />
药 用 洗 发 剂 洗 头 。 保 持 皮 肤 皱 褶 清 洁 、 干 爽 。<br />
• 完 好 的 皮 肤 可 使 用 玉 米 粉 、 非 香 水 滑 石 粉 和 婴 儿 爽 身 粉 。 如 出 现 湿 性 脱 皮 , 应 避 免 使 用 这 些<br />
产 品 , 因 为 它 们 会 导 致 真 菌 和 细 菌 感 染 。<br />
喉 咙 和 口 腔<br />
至 于 头 部 和 颈 项 治 疗 , 放 射 肿 瘤 科 医 生 会 尽 量 避 免 照 射 到 不 受 疾 病 影 响 的 范 围 , 亦 即 如 果<br />
不 是 要 治 疗 的 器 官 , 口 腔 将 受 到 保 护 。 和 皮 肤 一 样 , 喉 咙 和 口 腔 布 满 对 放 射 产 生 反 应 的 粘<br />
膜 。 您 可 能 会 发 生 粘 膜 炎 , 出 现 喉 咙 和 口 腔 溃 疡 的 症 状 。 整 个 或 局 部 口 腔 治 疗 会 增 加 唾 液 和<br />
粘 液 产 生 , 使 口 腔 内 带 有 粘 性 , 进 而 导 致 口 干 和 味 觉 出 现 变 化 。<br />
以 下 建 议 将 能 协 助 您 更 好 地 应 对 这 些 副 作 用 :<br />
• 常 小 啜 饮 料 , 避 免 喝 非 碳 酸 及 原 味 饮 料 。<br />
• 使 用 非 酒 精 漱 口 水 , 以 减 少 口 腔 内 的 粘 性 。<br />
• 使 用 止 咳 药 , 减 少 抽 烟 及 喝 酒 。<br />
• 如 果 饮 食 困 难 , 应 改 吃 流 体 食 物 , 以 及 避 免 干 、 辣 食 物 和 糯 米 饭 。<br />
• 选 择 液 体 营 养 品 或 代 餐 饮 料 。 应 少 量 多 餐 。<br />
• 使 用 软 毛 牙 刷 , 以 避 免 牙 龈 损 伤 , 以 及 使 用 非 酒 精 漱 口 水 。 最 后 , 在 口 腔 内 侧 涂 上 一 层 口 腔<br />
滋 润 膏 。 治 疗 结 束 后 , 继 续 进 行 口 腔 护 理 和 定 期 光 顾 牙 医 。 进 行 口 腔 放 射 后 , 不 宜 拔 牙 。<br />
• 如 有 任 何 不 适 , 应 咨 询 放 射 肿 瘤 科 医 生 的 意 见 。<br />
食 道 、 肠 、 膀 胱 和 直 肠<br />
食 道 、 肠 、 膀 胱 和 直 肠 的 粘 膜 层 会 发 生 粘<br />
膜 炎 , 其 症 状 包 括 这 些 器 官 发 炎 和 功 能 障<br />
碍 。 胸 腔 放 射 治 疗 会 影 响 吞 咽 功 能 , 导 致 声<br />
音 沙 哑 或 食 道 和 气 管 感 染 。 骨 盆 放 射 治 疗<br />
会 导 致 下 腹 不 适 和 小 便 时 感 到 灼 痛 。 此 外 ,<br />
大 小 便 的 次 数 也 会 增 加 。<br />
以 下 建 议 将 能 协 助 您 更 好 地 应 对 这 些 副<br />
作 用 :<br />
• 常 喝 水 或 其 他 液 体 , 让 身 体 保 持 充 足 的<br />
水 分 。<br />
• 控 制 水 果 、 乳 制 品 和 各 种 纤 维 食 物 的 摄<br />
取 , 让 粪 便 保 持 柔 软 , 以 避 免 直 肠 在 排<br />
便 时 受 损 或 发 炎 。<br />
• 如 果 您 发 现 痰 、 尿 或 粪 便 中 有 血 迹 , 或 者<br />
副 作 用 加 剧 、 频 频 发 生 , 还 会 呕 吐 或 发<br />
烧 , 应 咨 询 放 射 肿 瘤 科 医 生 的 意 见 。<br />
• 接 受 骨 盆 放 射 治 疗 女 病 人 应 常 冲 洗 或 清<br />
洗 阴 道 , 以 减 少 感 染 的 风 险 和 避 免 阴 道<br />
变 窄 。 您 可 向 医 生 咨 询 适 当 的 清 洗 液 和<br />
清 洗 方 法 。<br />
关 节 活 动<br />
接 受 胸 腔 手 术 和 / 或 上 臂 下 方 放 射 治 疗 后<br />
往 往 会 留 下 疤 痕 。 这 会 影 响 关 节 活 动 的 灵<br />
活 度 , 导 致 您 的 上 臂 活 动 僵 硬 。 每 天 把 手<br />
臂 举 及 头 顶 , 有 助 于 减 少 肩 关 节 僵 硬 。<br />
整 体 健 康 和 食 欲<br />
接 受 放 射 治 疗 的 病 人 也 许 会 感 到 疲 劳 、 食<br />
欲 不 振 、 反 胃 , 有 时 候 也 会 呕 吐 。 这 些 反 应<br />
可 能 与 放 射 治 疗 有 直 接 关 系 , 但 也 有 可 能<br />
是 诊 断 引 发 的 情 绪 负 担 和 对 治 疗 不 确 定<br />
性 的 恐 惧 造 成 的 。 处 方 药 可 有 效 解 决 反 胃<br />
和 呕 吐 的 问 题 。 白 天 小 睡 片 刻 可 补 充 您 的<br />
体 能 。<br />
结 语<br />
一 般 来 说 , 上 述 均 属 短 期 的 放 射<br />
副 作 用 。 这 些 副 作 用 不 应 影 响 您<br />
的 工 作 或 日 常 生 活 。 但 是 , 您 应<br />
在 放 射 治 疗 期 间 逐 渐 减 少 体 力 活<br />
动 , 以 及 在 治 疗 结 束 后 马 上 减 少<br />
体 力 活 动 。<br />

癌 症 治 疗 后 的<br />
健 康 计 划<br />
许 多 癌 症 幸 存 者 往 往 会 在 治 疗 后 寻 方 设 法 降 低 病<br />
情 复 发 的 机 率 。 有 些 人 担 心 他 们 的 饮 食 习 惯 、 生<br />
活 中 所 面 对 的 压 力 或 在 治 疗 期 间 所 接 触 的 化 学 物<br />
质 会 提 高 癌 症 复 发 的 风 险 。 癌 症 幸 存 者 也 认 为 ,<br />
他 们 应 该 趁 此 机 会 检 视 照 顾 自 己 身 体 健 康 的 方<br />
式 。 这 是 罹 患 癌 症 后 开 始 健 康 生 活 的 最 好 时 机 。<br />
癌 症 治 疗 后 注 重 饮 食 习 惯<br />
1 摄 取 各 种 健 康 食 物 。<br />
• 每 天 摄 取 五 份 或 更 多 的 蔬 果 。<br />
• 选 择 全 谷 食 品 , 而 不 是 加 工<br />
精 制 谷 类 和 糖 。<br />
• 选 择 有 助 于 维 持 正 常 体 重 的<br />
食 物 。<br />
• 少 吃 红 肉 , 尤 其 是 高 脂 肪 或 加<br />
工 肉 类 。<br />
2 保 持 正 常 体 重 。 你 的 身 体 质 量 指<br />
数 尽 量 维 持 在 18.5 至 22.9 公 斤 /<br />
米 2<br />
之 间 。<br />
3 少 喝 酒 。 研 究 显 示 , 喝 酒 会 提 高<br />
您 罹 患 某 些 癌 症 的 机 率 , 例 如 肝<br />
癌 、 胃 癌 和 食 道 癌 。<br />
癌 症 治 疗 后 勤 做 运 动<br />
每 个 人 都 知 道 运 动 有 很 多 益 处 ,<br />
例 如 提 高 体 能 水 平 和 帮 助 减 轻 体<br />
重 。 除 此 之 外 , 您 或 许 往 往 会 忽<br />
略 , 运 动 其 实 也 可 以 改 善 您 的 情<br />
绪 , 让 您 感 觉 美 好 。<br />
研 究 人 员 针 对 癌 症 治 疗 后 做 运 动<br />
是 否 会 影 响 存 活 率 进 行 研 究 , 许<br />
多 研 究 结 果 显 示 , 每 天 或 几 乎 每<br />
天 做 大 约 30 分 钟 的 适 量 运 动 轻<br />
快 步 行 、 游 泳 、 骑 脚 车 , 有<br />
助 于 :<br />
• 减 轻 焦 虑 和 忧 郁<br />
• 改 善 情 绪<br />
• 提 高 自 信 心<br />
• 减 少 疲 劳 、 反 胃 、 疼 痛 和 腹<br />
泻 等 症 状<br />
癌 症 幸 存 者 应 该 慢 慢 地 展 开 锻 炼<br />
计 划 , 逐 步 增 加 运 动 量 。 有 些 人<br />
可 能 在 运 动 时 也 需 要 特 别 小 心 。<br />
因 此 , 您 最 好 在 开 始 任 何 锻 炼 计<br />
划 前 咨 询 医 生 的 意 见 。<br />
后 续 护 理<br />
在 第 一 次 复 诊 时 , 您 应 该 咨 询<br />
医 生 :<br />
• 您 需 要 进 行 的 检 查 和 后 续 护<br />
理 , 以 及 进 行 的 次 数 和 频 率 。<br />
• 癌 症 治 疗 后 可 能 会 出 现 的 健 康<br />
问 题 , 以 及 预 防 、 减 少 或 解 决<br />
这 些 问 题 的 方 法 。<br />
每 次 复 诊 时 , 告 诉 您 的 医 生 :<br />
• 您 认 为 可 能 是 癌 症 复 发 的<br />
症 状 。<br />
• 任 何 令 您 困 扰 的 疼 痛 。<br />
• 影 响 您 的 日 常 生 活 或 给 您 带 来<br />
困 扰 的 健 康 问 题 , 例 如 疲 劳 、<br />

癌 症 会 影 响 一 个 人 的 健 康 状<br />
况 , 也 会 影 响 一 个 人 感 觉 、 思<br />
考 和 做 喜 欢 的 事 情 的 方 式 。 在<br />
整 个 治 疗 的 过 程 中 , 病 人 除 了<br />
会 产 生 许 多 意 想 不 到 的 情 绪<br />
变 化 外 , 脑 部 的 运 作 方 式 可 能<br />
也 会 有 所 改 变 。 因 此 , 病 人 在<br />
治 疗 后 不 只 要 照 顾 身 体 , 还 要<br />
关 注 情 绪 上 的 变 化 。<br />
每 个 人 应 对 癌 症 的 经 验 都 不 尽 相 同 ,<br />
所 面 对 的 感 觉 、 情 绪 变 化 和 恐 惧 也 因<br />
人 而 异 。 病 人 成 长 的 价 值 观 也 会 影 响<br />
他 对 癌 症 的 看 法 和 应 对 方 式 。 有 些 人<br />
会 觉 得 他 们 必 须 坚 强 和 保 护 家 人 及 朋<br />
友 , 有 些 人 则 需 要 亲 人 或 其 他 癌 症 幸<br />
存 者 的 支 持 , 或 者 从 信 仰 中 获 得 应 对<br />
癌 症 的 力 量 。 有 些 人 会 寻 求 辅 导 员 和<br />
外 人 的 协 助 , 也 有 些 人 对 这 种 方 式 感<br />
到 不 自 在 。 不 管 是 哪 一 种 方 式 , 病 人<br />
最 重 要 的 是 选 择 适 合 自 己 的 方 法 , 不<br />
要 和 他 人 作 比 较 。<br />
担 心 癌 症 复 发<br />
担 心 癌 症 复 发 是 正 常 的 反 应 , 尤 其<br />
是 在 治 疗 后 的 第 一 年 内 。 这 是 病 人 治<br />
疗 后 最 常 见 的 忧 虑 之 一 。 即 使 是 多 年<br />
以 后 , 病 人 还 是 会 有 可 能 心 有 余 悸 。<br />
有 些 人 还 会 因 此 而 无 法 好 好 地 吃 饭 、<br />
睡 觉 、 享 受 生 活 , 甚 至 对 复 诊 也 感 到<br />
恐 惧 。<br />
有 位 女 病 患 问 :“ 如 果 癌 症 复 发 , 我<br />
该 怎 么 办 ? 我 从 来 没 有 想 过 我 可 以 熬<br />
过 第 一 次 。”<br />
当 然 , 不 是 每 个 人 都 有 同 样 的 反 应 。 也 有 一 位 癌 症 幸 存 者 这<br />
么 说 :“ 癌 症 是 生 活 的 一 部 分 , 我 们 总 会 有 希 望 的 。”<br />
很 多 幸 存 者 都 表 示 , 他 们 担 心 癌 症 复 发 的 恐 惧 会 逐 渐 转 弱 。 他 们 也 发 现 自 己 想 起<br />
癌 症 的 次 数 会 越 来 越 少 。 但 是 , 即 使 是 多 年 以 后 , 他 们 也 可 能 会 因 为 某 些 情 况 而<br />
担 心 自 己 的 健 康 状 况 , 其 中 包 括 :<br />
• 复 诊<br />
• 特 定 事 件 的 周 年 日 , 例 如 确 诊 、 动 手 术 或 疗 程 结 束<br />
• 生 日<br />
• 家 庭 成 员 患 病<br />
• 出 现 类 似 他 / 她 患 癌 症 时 的 症 状<br />
• 有 人 因 癌 症 去 世<br />
• 唤 起 个 人 回 忆 的 事 物 。 例 如 , 一 位 男 幸 存 者 说 , 他 每 次 进 行 化 疗 后 总 会 光 顾<br />
某 个 甜 品 摊 , 因 为 那 里 的 姜 汁 番 薯 糖 水 是 他 唯 一 吃 得 下 的 食 物 。 疗 程 结 束<br />
后 , 他 就 不 再 光 顾 那 个 甜 品 摊 , 因 为 这 会 让 他 想 起 疗 程 和 觉 得 “ 反 胃 ”。<br />
回 想 和 提 及 这 种 感 觉 总 让 人 难 受 。 有 些 人 只 想 向 前 看 , 把 一 切 有 关 癌 症 的 想 法 抛 诸<br />
脑 后 。 虽 然 你 不 可 以 让 癌 症 “ 操 控 你 的 生 活 ”, 但 这 绝 对 不 是 一 件 轻 而 易 举 的 事 。<br />
你 必 须 要 有 正 面 、 积 极 的 态 度 , 也 就 是 说 , 即 使 在 艰 难 的 时 刻 , 你 也 要 往 好 的 方<br />
面 想 , 尽 量 抱 有 希 望 。 你 必 须 凭 靠 这 股 正 面 、 积 极 的 力 量 , 专 注 于 身 体 状 况 , 并<br />
且 尽 量 做 一 些 可 以 保 持 健 康 的 事 情 。<br />

LOOK FEAR IN THE FACE<br />

May / June 2010<br />
Eleanor Roosevelt, known famously for her<br />
involvement in human rights issues, once said:<br />
“You gain strength, courage, and confidence by<br />
every experience in which you really stop to look<br />
fear in the face. You are able to say to yourself, ‘I<br />
have lived through this horror. I can take the next<br />
thing that comes along.’... You must do the thing<br />
you think you cannot do.”<br />
Indeed, cancer survivors must be<br />
applauded for having walked the<br />
long and arduous journey bravely.<br />
Family members and caregivers who<br />
have accompanied their love ones<br />
through cancer treatment would<br />
know that they did not have it easy.<br />
So what happens after beating<br />
cancer into remission?<br />
“Physical, emotional, and financial<br />
hardships often persist for most<br />
of them years after diagnosis and<br />
treatment. They may also face<br />
challenges such as employment<br />
problems, psychological struggles<br />
and the strain on personal<br />
relationships and, not to mention,<br />
the fear of recurrence,” shared<br />
Dr Yap Swee Peng, acting Director<br />
for Public Education and Patient<br />
Support Unit of <strong>National</strong> <strong>Cancer</strong><br />
<strong>Centre</strong> <strong>Singapore</strong> (NCCS).<br />
“Hence, family support and seeking<br />
timely professional help from<br />
counsellors, medical social workers,<br />
among others, are essential in helping<br />
patients get back on their feet.”<br />
Despite the many challenges cancer<br />
survivors have to face, a majority<br />
of them live a fulfilling life and is a<br />
source of inspiration for those around<br />
them. One such brave individual<br />
is Mr Ezzy Wang, the epitome of<br />
survivorship. Despite losing his right<br />
lower limb to cancer, he endured in<br />
his exercise regime, which includes<br />
cycling 50km around <strong>Singapore</strong>.<br />
To honour all who have fought a<br />
hard battle with cancer, the NCCS<br />
will host a day of fun and adventure<br />
for more than 400 cancer survivors,<br />
including their families, friends<br />
and the healthcare providers at the<br />
<strong>Singapore</strong> Zoo on Saturday, 26th June<br />
2010 from 8.30am to 1pm.<br />
The event not only serves as an<br />
opportunity for cancer survivors to meet<br />
and spur each other to live better but<br />
also to equip them with the knowledge<br />
of doing so. Participants can partake<br />
in an exciting Zoomanji Adventure or<br />
visit the carnival game stalls and snack<br />
booths when hunger strikes. Mr Wang<br />
will also be there to share some tips on<br />
challenging negative thoughts.<br />
After all, surviving cancer<br />
boils down to three key<br />
elements - knowledge,<br />
hope and inspiration!<br />

NCCS ON TRACK IN ITS<br />
FOCUS ON CUTTING-EDGE<br />
CANCER RESEARCH<br />
<strong>Singapore</strong> is laying a strong foundation for its<br />
cancer research programme with the growing<br />
number of doctors returning from overseas<br />
training stint to put their knowledge to good use<br />
by conducting research and conducting clinical<br />
trials. Veronica Lee reports.<br />
As clinical trials are fundamental<br />
to cancer research, the expertise<br />
of these doctors may see more<br />
translational research that would<br />
contribute to the development of a strong<br />
cancer research base at the <strong>National</strong><br />
<strong>Cancer</strong> <strong>Centre</strong> <strong>Singapore</strong>.<br />
Two doctors who recently returned to<br />
join the talent pool at the NCCS are<br />
Dr Daniel Tan and Dr Iain Tan, both<br />
of whom are Registrars from the<br />
Department of Medical Oncology.<br />
While at the UK’s Royal Marsden Hospital<br />
on a <strong>National</strong> Medical Research Council<br />
(NMRC) fellowship, Dr Daniel Tan was the<br />
primary fellow in charge of a trial that tested<br />
for the safety and toxicity of a novel agent<br />
used for the first time in human bodies.<br />
He supervised the administration of the<br />
trial and monitored a maiden group of<br />
patients in the UK receiving these drugs<br />
and coordinated multiple investigations<br />
that were indicators of intended efficacy.<br />
The trial was selected for oral presentation<br />
in the Developmental Therapeutics session<br />
at the recent American Society of Clinical<br />
Oncology (ASCO) annual meeting, and<br />
Dr Tan was conferred a Merit Award by<br />
ASCO for his efforts.<br />
The trial was to determine a safe<br />
and tolerable dose of the new agent<br />
targeting the mTOR pathway - a<br />
promising therapeutic pathway in<br />
cancer, as well as find the best<br />
techniques of administering it to<br />
patients. The drug in question is an<br />
improved design compared to the<br />
mTORC1 inhibitors currently used in<br />
clinical practice.<br />
In these early studies, it is<br />
reassuring that some of the<br />
biomarker analyses suggest that the<br />
agent was hitting its intended target<br />
within the schedules explored.<br />
On what contributed to the success of<br />
the trial, Dr Daniel Tan said, “Phase 1<br />
trials are typically challenging. They<br />
require tremendous coordination<br />
of clinical care, logistics and<br />
administration. I am thankful for the<br />
dedication of the trial team.”<br />
He also expressed gratitude to<br />
Professor Stan Kaye and Dr Johann<br />
De Bono from the Royal Marsden<br />
Hospital, both leaders in the field<br />
of drug development who have<br />
provided “invaluable guidance<br />
and mentorship.”<br />
Traditionally, the attrition rate is high<br />
with many compounds from the drug<br />
development pipeline failing to make it<br />
past a Phase 1, 2 and 3 Trial. However, the<br />
odds are now improving with an increasing<br />
incorporation of biomarkers that determine<br />
the best way to use the drug. In the case of<br />
this trial, it exhibited encouraging results<br />
when the agent showed that it was hitting its<br />
intended target, with some patients actually<br />
responding well to the agent.<br />
Dr Daniel Tan attributed this to a paradigm<br />
shift in drug development. “As majority of<br />
modern drugs are created and modelled<br />
purposefully rather than through serendipitous<br />
findings, early phase trials are now expanding<br />
from dose titration safety studies to include<br />
more information that can provide potential<br />
insights to drug effect, resistance and even<br />
disease biology. We see an increasing number<br />
of patients reap benefits even at an early stage,<br />
as evidenced in recent Phase 1 trial findings<br />
on PARP and BRAF inhibitors published in the<br />
New England Journal of Medicine.”<br />
“The positive outcomes from such early<br />
trials certainly help in the development of<br />
specific novel therapeutics, and determine<br />
a suitable patient base. Most importantly, it<br />
will accelerate the approval of useful drugs<br />
so that patients can benefit’, Dr Tan added.

Many patients with advanced stage cancer<br />
at diagnosis had predominantly been the<br />
targeted group for trials. These patients are<br />
ideal candidates for clinical trial as they<br />
are usually at the end of their journey for a<br />
cure. One such group is patients suffering<br />
from gastric cancer.<br />
Gastric <strong>Cancer</strong> is the second leading cause<br />
of global cancer mortality and is particularly<br />
common in Asia. It is a difficult cancer to<br />
treat as symptoms appear late. At diagnosis,<br />
many patients already have stage four cancer<br />
for which surgery is no longer possible.<br />
Among patients who do undergo surgery<br />
upon early detection, the disease can recur.<br />
There are several effective palliative<br />
treatment options available and whilst these<br />
are unable to completely eradicate the<br />
disease, they can control the cancer, prolong<br />
survival and most importantly, provide much<br />
needed symptom relief for patients.<br />

The lack of reliable tests to select the<br />
most appropriate treatment regimen<br />
for individual patients has been the<br />
impetus behind Dr Iain Tan’s research<br />
into understanding the biology of<br />
gastric cancer.<br />
Working under the supervision of his<br />
clinical Head of Department,<br />
Dr Toh Han Chong and his scientific<br />
supervisor, A/P Patrick Tan from Duke-<br />
NUS Graduate Medical School,<br />
Dr Iain Tan studied more than 400<br />
cancer samples derived from patients<br />
in four countries. The study revealed<br />
that whilst there was indeed substantial<br />
molecular complexity and heterogeneity<br />
at a fundamental level, each gastric<br />
cancer conformed to one of two major<br />
molecular patterns which the team<br />
termed as ‘intrinsic signatures’.<br />
It was also found that the two intrinsic<br />
subtypes of gastric cancers respond<br />
differently to drugs that are presently<br />
being used in the treatment of gastric<br />
cancer. They also displayed strikingly<br />
different patterns of genetic aberrations<br />
that provided a reason for further<br />
development of subtype-specific targeted<br />
therapies. The findings were recently<br />
presented at the American Association of<br />
<strong>Cancer</strong> Research annual meeting, where<br />
he was awarded the meritorious scholarin-training<br />
award.<br />
After demonstrating effectiveness in<br />
predicting treatment responses in the<br />
controlled laboratory environment, the<br />
next step was to evaluate if it could<br />
be translated to the clinic. Dr Iain Tan<br />
then developed a research proposal to<br />
leverage upon cutting edge genomic<br />
tools to correlate tumor genetic profiles<br />
with patient treatment outcomes so as<br />
to rapidly and efficiently obtain a timely<br />
answer to his scientific enquiry. For<br />
conceiving this cutting-edge approach<br />
with the potential of providing direct<br />
benefit to patients, Dr Iain Tan received<br />
the ASCO Young Investigator Award<br />
and was the only recipient from an<br />
institution outside of North America to<br />
receive the award.<br />
Predicting good outcomes with specific<br />
chemotherapeutics had been the driving<br />
force to Dr Iain Tan’s research. With<br />
an aim to be a physician scientist in<br />
gastrointestinal cancer, the field will be<br />
given a boost and will definitely become<br />
one of the major pillars of clinical<br />
expertise at NCCS.<br />
Patients can however experience varied<br />
responses to the available treatment<br />
regimens. Hence, choosing the right regimen<br />
for each patient is important because<br />
achieving initial control of the cancer leads<br />
to an improved clinical outcome and many<br />
patients will be unfit for subsequent attempts<br />
at treatment if their cancer degenerates early.<br />
The achievements of NCCS oncologists, winning<br />
worldwide recognition for their work, is another step<br />
in the right direction for NCCS to achieve its mission to<br />
become the leading global cancer centre.

ARE YOU HAPPY?<br />
SALUBRIS<br />
May / June 2010<br />
If there is such a thing as the secret<br />
to happiness, it is this: Happiness<br />
comes from within.<br />
Last year, <strong>Singapore</strong> was placed in<br />
an unremarkable 49th out of 140<br />
countries in The Happy Planet Index.<br />
As a materially wealthy nation, the results<br />
unleashed much soul-searching about the way<br />
<strong>Singapore</strong>ans truly view life and happiness.<br />
The common connotation is that the stresses of<br />
living in a society that focused on materialism<br />
have made <strong>Singapore</strong>ans less happy than their<br />
peers in many other countries.<br />
Concerned with the rising levels of stress in<br />
<strong>Singapore</strong>, Philip Merry - founder of the Philip<br />
Merry Consulting Group, organised the 1st<br />
Asian Happiness and Well-Being Conference<br />
that led the search for <strong>Singapore</strong>’s happiest<br />
person last year in 2009.<br />
“If you have people who love you, good<br />
health, food on the table and a stable job, you<br />
are already happier than nine in 10 people<br />
on earth,” he said. “Essentially, happiness<br />
comes from having meaning (contributing to<br />
something outside of yourself), authenticity<br />
(being your true self) and connection (having<br />
friends and family) in our life.”<br />
Philip is currently planning the 2nd Happiness<br />
Conference, this time focusing on Resilience<br />
& Courage. This year’s theme is linked to<br />
the economic downturn and centred on<br />
how resilience skills can help people thrive<br />
in difficult times. <strong>National</strong> <strong>Cancer</strong> <strong>Centre</strong><br />
<strong>Singapore</strong> (NCCS) is the healthcare partner for<br />
this year’s conference.<br />
Resilience is the positive behaviour<br />
we show when facing adversity that<br />
allows us to bounce back, and courage<br />
is our ability to confront our fears and<br />
problems. When things go wrong –<br />
such as the loss of health, relationships,<br />
jobs, savings or hope in a better future,<br />
resilience can be another opportunity<br />
for learning effective coping strategies.<br />
When asked for the reason behind<br />
NCCS partnering this meaningful<br />
conference, Eugene Sng, Programme<br />
Director of NCC Foundation,<br />
NCCS shared: “<strong>Cancer</strong> patients<br />
and caregivers face difficulties with<br />
resilience every day. NCCS is happy<br />
to be the healthcare partner of<br />
Resilience & Courage as we believe<br />
resilience skills will add a huge value<br />
to the lives of our patients, caregivers<br />
and staff.”<br />
In enabling our healthcare practitioners to<br />
benefit from this talk, two lunch seminars<br />
were held at Singhealth, where Philip<br />
shared his secrets to building resilience in<br />
life and at work.<br />
Resilience & Courage is a community<br />
outreach effort that will help bring out the<br />
true meaning of resilience, and help people<br />
recognise that resilience is already within us.<br />
A search for <strong>Singapore</strong>’s resilient heroes will<br />
also be conducted later this year.<br />
As Philip says, “If this<br />
conference can make<br />
just one person’s life<br />
better and happier,<br />
we will be happy,”<br />
