    • Research Report Issue 24 • November 2013 FEATURED: Forgotten cancers 2 Bringing research funds and resources to bear on this area Our Staff 2 5 minutes with Dr Lini NairShalliker Our Insights 3 A small change to Death Registration could save lives Research Discovery 4 How cancer cells learn to resist drug treatments CLEAR Study: We can now make our data available to cancer researchers Cancer Council NSW invites other cancer researchers to discuss projects for collaboration. The NSW CLEAR study has collected data from over 9,000 people with and without cancer to provide a better understanding of the genetic and environmental causes of cancer in NSW. The study was designed as an open resource for cancer researchers, and the data and blood samples have now reached sufficient maturity to be made available to the cancer research community. Scientists can use the CLEAR data and blood samples to evaluate risk factors for cancer. Particular interest will be links between cancer and smoking, infectious agents, hormones, sun exposure and sleep patterns, BMI/physical activity, and alcohol. As the CLEAR Study is an open resource, scientists may apply to use questionnaire data and blood samples for any cancer research project, subject to scientific and ethical approval, without collaboration with Cancer Council NSW. However, we also encourage researchers to discuss with us opportunities for collaborative projects, especially those which bring expertise outside our areas of content knowledge.

    • Forgotten cancers cause more than a third of all cancer deaths They account for 35% of all NSW cancer deaths yet are under-funded and under-researched. “Many cancer types are grossly under-funded and under-resourced, yet they are among the most common causes of cancer deaths in Australia. We call these the forgotten cancers,” said A/Professor Freddy Sitas of Cancer Council NSW. Figures recently released by Cancer Council NSW show pancreatic and thyroid cancer have seen the least improvements in cancer death reduction over a 20 year study period — only a 6% reduction in death rate, while liver cancer has seen an increase. Under-funded cancers such as pancreatic cancer, cancer of the unknown primary, and liver cancer are in the top ten most common causes of cancer death in Australia, while brain cancer remains the leading cause of cancer death in children and young people. A reminder that forgotten cancers are killing people yet receive little attention, funding or support for their sufferers On average, 40 Australians die from these forgotten cancers every day. Because of this, Cancer Council NSW has made many of these cancers a key focus for new research. Brain and pancreatic cancer are our second and third most funded cancers, each receiving close to $1m in research funding this year.

I started as a PhD student through the University of Sydney. After that I was employed as a Research Fellow for the CLEAR Study in 2011. I manage the operations and strategic direction of the CLEAR Study under the guidance of the study’s investigators. How will the CLEAR Study benefit Cancer Council NSW? By reinforcing the organisation as a reputable and innovative research institution in the forefront of cancer research. From your perspective, why is the CLEAR Study important? Dr Visalini Nair-Shalliker The aim of CLEAR is to study gene-environment interactions and to try to discover whether a disease like cancer can be prevented We are close to reaching the initial 10,000 by reducing our exposure to environmental risks. It is one of the few studies recruitment target for the CLEAR Study. Only that has such a concise collection of a variety of environmental, social and 450 to go! Our next target will be 25,000. lifestyle factors as well as blood and tissue samples. And we are beginning to promote the What are the aims for the CLEAR Study now? availability of the data (bloods and We are focussing on recruiting from our culturally and linguistically diverse questionnaires) to other researchers with the community. We have translated our study materials into 5 languages and are goal of attracting collaborators. looking for help to distribute this new information.

    • Here’s a simple question that could save lives: “Was the deceased a smoker five years ago?” A new report highlights how this simple yes/no question about smoking on South African death registration forms has led to new understandings about deaths caused by smoking, and provided a valuable profile of the effect of smoking on different population groups in that country. This new insight has stimulated leading Australian researchers to call for a similar question on smoking to be included on death registration forms in Australia and around the world. “…a simple yes/no question on death registration forms has led to new insights about deaths caused by smoking.” Lead author and cancer epidemiologist, A/Professor Freddy Sitas, Cancer Council NSW, plans to present these key findings to the World Health Organization. “This model should become international best practice for any country that has reasonable death certification.” Eminent international cancer epidemiologist, Professor Sir Richard Peto from Oxford University, and another lead author on the study, adds: “This is a cheap and easy intervention that ought to be implemented worldwide.” South Africa is the only country to record smoking status on the death certificate. “Working with colleagues in South Africa and the UK we analysed half a million deaths from South Africa, making this one of the largest studies on death from tobacco in the world,” said A/Professor Sitas. ”What surprised us were the striking differences in the profile of deaths from smoking in each population group — in the black population we found that the main way it killed was by increasing the mortality rate from tuberculosis, cancer and other lung diseases. In the white population we saw an increase in risk from cancer and heart disease, but surprisingly an increase in respiratory diseases. The mixed race population smoked more than any other group and had about double the death rate from smoking than that of white South Africans. This is of real relevance to countries with large multicultural populations, like Australia.” Leading cause of death in smokers in South Africa Population group Smokers Black White Mixed Leading cause of death: 1 2 3 Male Female Male Female Male Female 50% 12% 47% 28% 68% 46% Tuberculosis Other respiratory disease Upper aerodigestive cancer Ischaemic heart disease Chronic obstructive pulmonary disease Lung cancer Tuberculosis Chronic obstructive pulmonary disease Other respiratory disease Question on South African Register of Death form Although smoking levels in Australia are declining, tobacco is still one of the leading causes of preventable deaths affecting 1519,000 people per annum. To arrive at these figures, Australia extrapolates estimates from other western countries, “but in a multicultural country like Australia we ought to be getting more accurate data and trends over a long period of time,” said A/Professor Sitas. “If we replicate this work in Australia the results could be more startling than expected. There could be a huge variation in smoking related deaths among our indigenous, migrant, rural populations, or those who are marginalised. Accurate information will help us focus our prevention programs. We could also find out more details about the range of diseases directly linked to smoking. There are about 60,000 doctors in Australia and about 150,000 deaths per annum. We are really not talking about a lot of extra work.” The study was funded by the South African Medical Research Council, the UK Medical Research Council, Cancer Council NSW, Cancer Research UK and the British Heart Foundation.

    • Cancer cells teach each other how to resist treatment It can take just four hours for a cancer cell to learn how to resist cancer drug treatments. Over time cancer cells can become resistant to drugs. Now A/Professor Mary Bebawy has made a remarkable discovery as to how it happens: she found that resistant cells actually share with other surrounding cells the ‘knowledge’ necessary to protect them from cancer treatments. A/Professor Mary Bebawy, together with Professor Georges Grau, found a previously unknown mechanism for cancer cells to teach each other how to resist treatment. A resistant cancer cell can shed tiny vesicles, or micro particles, from its surface. These vesicles are actually tiny packages full of genetic information that act as messengers Drug resistant cells can share their ‘knowledge’ with surrounding cells between the cancer cells. The micro particles dock onto a drug-sensitive cancer cell and within two hours they release their contents into the cell. As early as four hours later that cell is multi-drug resistant cancer cell. If A/Professor Bebawy and her team can understand how these cells resist treatments, this could lead to the development of new drugs able to circumvent them or tests to detect when cells are becoming resistant to therapy.
