IntroductionMesothelioma is a usually fatal cancer which typically occurs 20 <strong>to</strong> 40 years afterexposure <strong>to</strong> asbes<strong>to</strong>s — although exposure does not necessarily result <strong>in</strong> the disease.All new cases of <strong>mesothelioma</strong> are notified <strong>to</strong> state and terri<strong>to</strong>ry Cancer Registries,as <strong>mesothelioma</strong> is a notifiable disease. These data are collected nationally by theAustralian Institute of Health and Welfare (AIHW) <strong>in</strong> the National Cancer StatisticsClear<strong>in</strong>g House (NCSCH). Information on deaths from <strong>mesothelioma</strong> is also collectedby the AIHW as part of the National Mortality Database. The AIHW publishes cancerdata <strong>in</strong> spreadsheets on its website. This report uses the <strong>mesothelioma</strong> data, andadditional data supplied by the state and terri<strong>to</strong>ry cancer registries <strong>to</strong> the AIHW, <strong>to</strong>report on the <strong>in</strong>cidence of new cases and deaths from <strong>mesothelioma</strong> by both ageand sex. In addition, trends over time are shown for the period <strong>1982</strong> <strong>to</strong> <strong>2008</strong> for thenumber of new cases, and from 1997 <strong>to</strong> 2007 for the number of deaths. The <strong>mortality</strong>section of this report is identical <strong>to</strong> that published <strong>in</strong> the previous edition because datafor <strong>2008</strong> are not yet available.Mesothelioma of the pleura (a cancer affect<strong>in</strong>g the protective l<strong>in</strong><strong>in</strong>g of the lung andchest cavity) was the most common form of <strong>mesothelioma</strong> diagnosed <strong>in</strong> Australia:<strong>in</strong>volv<strong>in</strong>g approximately 94% of cases s<strong>in</strong>ce <strong>1982</strong>. Mesothelioma of the peri<strong>to</strong>neum(a cancer affect<strong>in</strong>g the abdom<strong>in</strong>al l<strong>in</strong><strong>in</strong>g) is a much less common diagnosis,account<strong>in</strong>g for approximately 5% of cases s<strong>in</strong>ce <strong>1982</strong>. The figures presented <strong>in</strong> thispublication <strong>in</strong>clude all forms of <strong>mesothelioma</strong>.Asbes<strong>to</strong>s production, use and control <strong>in</strong> AustraliaIn Australia, more chrysotile (white asbes<strong>to</strong>s) than amphibole (blue and brown)asbes<strong>to</strong>s was m<strong>in</strong>ed until 1939. New South Wales, the first state <strong>to</strong> m<strong>in</strong>e asbes<strong>to</strong>s,produced the largest <strong>to</strong>nnages of chrysotile (until 1983) as well as smaller quantitiesof amphibole (until 1949). With the commencement of m<strong>in</strong><strong>in</strong>g <strong>in</strong> Wittenoom <strong>in</strong> WesternAustralia <strong>in</strong> 1937, crocidolite (blue asbes<strong>to</strong>s) dom<strong>in</strong>ated production until f<strong>in</strong>al closureof the m<strong>in</strong>e <strong>in</strong> 1966. The ma<strong>in</strong> sources of raw asbes<strong>to</strong>s imports were from Canada(chrysotile) and South Africa (crocidolite and amosite (brown asbes<strong>to</strong>s)). Consumptionpeaked <strong>in</strong> about 1975 at approximately 70 000 <strong>to</strong>nnes per year.In addition <strong>to</strong> imports of asbes<strong>to</strong>s fibre, Australia also imported many manufacturedasbes<strong>to</strong>s products, <strong>in</strong>clud<strong>in</strong>g asbes<strong>to</strong>s conta<strong>in</strong><strong>in</strong>g cement articles, yarn, cord andfabric, jo<strong>in</strong>t and millboard, friction materials and gaskets. The ma<strong>in</strong> sources of supplywere the United K<strong>in</strong>gdom (UK), United States of America (USA), Federal Republic ofGermany and Japan. With the clos<strong>in</strong>g of the crocidolite m<strong>in</strong>e at Wittenoom, Australianasbes<strong>to</strong>s production and exports decl<strong>in</strong>ed. Imports of chrysotile also started <strong>to</strong>decl<strong>in</strong>e.In Australia, over 60% of all production and 90% of all consumption of asbes<strong>to</strong>s fibrewas used <strong>in</strong> the asbes<strong>to</strong>s cement manufactur<strong>in</strong>g <strong>in</strong>dustry. From about 1940 <strong>to</strong> the late1960s all three types of asbes<strong>to</strong>s were used <strong>in</strong> this <strong>in</strong>dustry. The use of crocidolitebegan be<strong>in</strong>g phased out from 1967. Amosite was used until the mid 1980s. Much ofthe <strong>in</strong>dustry output rema<strong>in</strong>s <strong>in</strong> service <strong>to</strong>day <strong>in</strong> the form of “fibro” houses and waterand sewerage pip<strong>in</strong>g. By 1954, Australia was number four <strong>in</strong> the Western world <strong>in</strong>gross consumption of asbes<strong>to</strong>s cement products, after the USA, UK and France: andclearly first on a per capita basis. After World War II <strong>to</strong> 1954, 70 000 asbes<strong>to</strong>s cementhouses were built <strong>in</strong> the state of New South Wales alone (52% of all houses built).In Australia, until the 1960s, 25% of all new hous<strong>in</strong>g was clad <strong>in</strong> asbes<strong>to</strong>s cement.Exposures <strong>to</strong> asbes<strong>to</strong>s <strong>in</strong> the past were very high <strong>in</strong> some <strong>in</strong>dustries and occupations:as much as 25 million particles per cubic foot (150 fibres/ml) <strong>in</strong> asbes<strong>to</strong>s pulverisorsand dis<strong>in</strong>tegra<strong>to</strong>rs <strong>in</strong> the asbes<strong>to</strong>s cement <strong>in</strong>dustry, and up <strong>to</strong> 600 fibres/ml amongbaggers at Wittenoom. The use of asbes<strong>to</strong>s products has been regulated s<strong>in</strong>ce the late1970s. A series of regulations adopted <strong>in</strong> the late 1970s and early 1980s by the variousMesothelioma <strong>in</strong> Australia 2012 ... 1


states imposed exposure limits of 0.1 fibres/ml for crocidolite and amosite, and 0.1-1.0fibres/ml for chrysotile. In July 2003, a revised national exposure standard for chrysotileasbes<strong>to</strong>s of 0.1 fibres/ml was declared by the National Occupational Health andSafety Commission (NOHSC). The prohibition of all forms of asbes<strong>to</strong>s was adoptedsimultaneously under regulations <strong>in</strong> each Australian jurisdiction and Australian Cus<strong>to</strong>mson 31 December 2003.A new national Model Code of Practice, How <strong>to</strong> Manage and Control Asbes<strong>to</strong>s <strong>in</strong>the Workplace, December 2011, is available as an electronic publication on theSafe Work Australia web site. This Code of Practice provides practical guidance forpersons conduct<strong>in</strong>g a bus<strong>in</strong>ess or undertak<strong>in</strong>g on how <strong>to</strong> manage risks associated withasbes<strong>to</strong>s and asbes<strong>to</strong>s conta<strong>in</strong><strong>in</strong>g material at the workplace and thereby m<strong>in</strong>imise the<strong>in</strong>cidence of asbes<strong>to</strong>s-related diseases such as <strong>mesothelioma</strong>, asbes<strong>to</strong>sis and lungcancer.Mesothelioma ProjectionsDue <strong>to</strong> the long latency between exposure <strong>to</strong> asbes<strong>to</strong>s and diagnosis of<strong>mesothelioma</strong>, typically between 20 and 40 years, it is expected that the <strong>in</strong>cidence of<strong>mesothelioma</strong> will not peak until after 2013. Clements et al (2007a) predict that thenumber of new cases <strong>in</strong> Australia will peak <strong>in</strong> 2017. In another study, Clements et al(2007b) used two different models <strong>to</strong> project the <strong>in</strong>cidence of <strong>mesothelioma</strong> <strong>in</strong> men<strong>in</strong> New South Wales. Us<strong>in</strong>g an age/birth cohort model, they predict that the numberof new cases would peak <strong>in</strong> 2021 and us<strong>in</strong>g a model based on potential exposure <strong>to</strong>asbes<strong>to</strong>s <strong>in</strong> terms of age and calendar year, they predict the peak would occur <strong>in</strong> 2014.The new Australian Mesothelioma RegistryIn February 2010, Safe Work Australia <strong>in</strong>itiated and funded the establishment ofa new Mesothelioma Registry (www.<strong>mesothelioma</strong>-<strong>australia</strong>.com). The registryis adm<strong>in</strong>istered by the Cancer Institute of New South Wales <strong>in</strong> association withthe Monash Centre for Occupational & Environmental Health. Besides receiv<strong>in</strong>gnotifications of new diagnosis of <strong>mesothelioma</strong> from all Australian cancer registries,consent<strong>in</strong>g patients are asked about their residential, occupational and environmentalhis<strong>to</strong>ry. The Registry management committee <strong>in</strong>cludes some of the lead<strong>in</strong>g experts <strong>in</strong>asbes<strong>to</strong>s-related disease <strong>in</strong> Australia.The aims of the Australian Mesothelioma Registry are <strong>to</strong>:• better understand the exact relationship between asbes<strong>to</strong>s exposure and<strong>mesothelioma</strong>• better understand the nature and levels of asbes<strong>to</strong>s exposure that can result <strong>in</strong><strong>mesothelioma</strong>• identify the groups of workers exposed <strong>to</strong> potentially dangerous levels of asbes<strong>to</strong>sand <strong>to</strong> prevent that exposure• assist the development of policies <strong>to</strong> best deal with the asbes<strong>to</strong>s still present <strong>in</strong> ourenvironment (ma<strong>in</strong>ly our built environment)• provide <strong>in</strong>formation <strong>to</strong> assist researchers <strong>in</strong> undertak<strong>in</strong>g <strong>in</strong>vestigations with the aimof prevent<strong>in</strong>g <strong>mesothelioma</strong> <strong>in</strong> the future, and• identify other potential exposures that may cause <strong>mesothelioma</strong>.2 ...

Incidence of <strong>mesothelioma</strong>New cases diagnosed <strong>in</strong> <strong>2008</strong>All cases of cancer <strong>in</strong> Australia are notifiable by legislation <strong>to</strong> state and terri<strong>to</strong>ry cancerregistries. These registries report <strong>to</strong> the NCSCH which is operated by the AIHW underthe supervision of the Australasian Association of Cancer Registries (AACR). Nationaldata on <strong>mesothelioma</strong> are available from <strong>1982</strong>. National data presented <strong>in</strong> this reportwere provided by the AIHW. State and terri<strong>to</strong>ry data were provided by the relevantregistry through the AIHW.Incidence <strong>in</strong> a calendar year is def<strong>in</strong>ed as the number of new cases of <strong>mesothelioma</strong>diagnosed <strong>in</strong> an Australian state or terri<strong>to</strong>ry <strong>in</strong> that year. In <strong>2008</strong>, there were 661 peoplediagnosed with <strong>mesothelioma</strong> <strong>in</strong> Australia. Of these new cases about four out of everyfive cases (82%) were men.Figure 1 New cases of <strong>mesothelioma</strong>: by age and sex, <strong>2008</strong>Number of new cases1101009080706050403020100MalesFemalesAge group (years)Figure 1 shows the distribution by age and sex of new cases of <strong>mesothelioma</strong>diagnosed <strong>in</strong> <strong>2008</strong>.

In <strong>2008</strong> the rate was7 new cases per 100 000 population (Figure 5). However, because of the relativelysmall number of women diagnosed, the rates are quite volatile.Age-standardisation is a method of adjust<strong>in</strong>g the crude <strong>in</strong>cidence rate <strong>to</strong> elim<strong>in</strong>atethe effect of differences <strong>in</strong> population age structures when compar<strong>in</strong>g crude rates fordifferent periods of time. By apply<strong>in</strong>g the observed age-specific death rates <strong>in</strong> eachyear <strong>to</strong> a standard population, the expected number of deaths can be calculated and amore comparable age-standardised rate can be calculated for each year.Figure 6 shows the age-standardised <strong>in</strong>cidence of new cases of <strong>mesothelioma</strong>(per 100 000 population) over the period <strong>1982</strong> <strong>to</strong> <strong>2008</strong>. The overall <strong>in</strong>cidence rate<strong>in</strong>creased from a m<strong>in</strong>imum of 1.1 new cases per 100 000 population <strong>in</strong> 1983 <strong>to</strong> amaximum of 3.2 <strong>in</strong> 2003.

<strong>in</strong> <strong>2008</strong> there were 5 new cases per 100 000 males. The age-standardised <strong>in</strong>cidencerate for women over the period ranged between 0.2 new cases per 100 000 females <strong>in</strong>1983 and at or near 1 new cases per 100 000 females <strong>in</strong> recent years.Because asbes<strong>to</strong>s exposure <strong>in</strong> the workplace and the general environment has nowbeen elim<strong>in</strong>ated or m<strong>in</strong>imised, the <strong>in</strong>cidence of new cases of <strong>mesothelioma</strong> <strong>in</strong> thepopulation is expected <strong>to</strong> decl<strong>in</strong>e. However, because of the long latency betweenexposure <strong>to</strong> asbes<strong>to</strong>s and diagnosis of <strong>mesothelioma</strong>, typically between 20 and40 years, it is expected that the <strong>in</strong>cidence of <strong>mesothelioma</strong> will not peak until 2014 <strong>to</strong>2021, depend<strong>in</strong>g on the projection methodology.

Deaths due <strong>to</strong> <strong>mesothelioma</strong> 1Deaths <strong>in</strong> 2007The cause of every Australian death is certified by a medical practitioner and recordedon a death certificate. These death certificates are required by state and terri<strong>to</strong>ryRegistrars of Births, Deaths and Marriages under jurisdiction specific legislation. Onbehalf of the Registrars these data are assembled, coded <strong>to</strong> the underly<strong>in</strong>g causeof death, and released by the Australian Bureau of Statistics (ABS). Cases wherethe underly<strong>in</strong>g cause of death was <strong>mesothelioma</strong> are discussed <strong>in</strong> this section. Dataon deaths due <strong>to</strong> <strong>mesothelioma</strong> are available from 1997 onwards, the year <strong>in</strong> whicha specific code for <strong>mesothelioma</strong> was added <strong>to</strong> the International Classification ofDiseases - 10th revision (ICD10).The <strong>in</strong>formation on deaths from <strong>mesothelioma</strong> <strong>in</strong> this section is based on the yearof death except for the most recent year 2007, where year of registration is used.The year of death and registration usually co<strong>in</strong>cide, although deaths at the end of acalendar year may be held over until the follow<strong>in</strong>g year, as will deaths whose causerequires further exam<strong>in</strong>ation by a coroner. In recent years less than 5% of deaths(all causes) were held over from one year <strong>to</strong> the next for process<strong>in</strong>g. This method ofreport<strong>in</strong>g the data allows the most recent year <strong>to</strong> be used.In 2007 there were 551 deaths registered with an underly<strong>in</strong>g cause of <strong>mesothelioma</strong>.Of these deaths, 464 (84%) were of men and 87 (16%) were of women.Figure 8 shows the age and sex distribution of those 551 decedents. Deaths amongyoung adults are rare: <strong>in</strong> 2007 the youngest deaths were <strong>in</strong> the 25–29 year age group.The graph shows that deaths due <strong>to</strong> <strong>mesothelioma</strong> were dist<strong>in</strong>ctly skewed <strong>to</strong>wards theolder age groups: this is particularly clear for the male decedents with 75% aged over65 years at the time of death. The comparable figure for female decedents was 70%.Figure 8 Deaths due <strong>to</strong> <strong>mesothelioma</strong>: by age and sex, 2007 (a)Number of deaths1009080706050403020100MalesFemalesAge group (years)(a) Data for 2007 is based on year of registration, not year of death.1.

Because of the relatively shortsurvival period from onset of the disease, the age related pattern of <strong>mortality</strong> is verysimilar <strong>to</strong> that for diagnosis. The <strong>mortality</strong> rate for men <strong>in</strong>creases considerably andsteadily with age, reach<strong>in</strong>g a maximum of 46 deaths per 100 000 population amongmen aged 80–84 years before decl<strong>in</strong><strong>in</strong>g <strong>to</strong> 31 <strong>in</strong> the open-ended age group of 85years and over. For women, the rates were lower, but also reached a maximum of 6deaths per 100 000 population among women <strong>in</strong> both the 80–84 and 85 years and overage groups.Trends over time, 1997 <strong>to</strong> 2007National dataThe overall number of deaths result<strong>in</strong>g from <strong>mesothelioma</strong> <strong>in</strong>creased over theperiod between 1997 and 2007.
