Summary
There is laboratory evidence that chemicals in green tea (poloyphenols) protect against cancer. Epidemiologic studies in humans have generally supported these findings, especially for breast cancer. This project is a crucial stepping stone towards future prospects of a large-scale trial using green tea extract. It will see if the protection extends to leukaemia and bowel cancer, and will identify the genetic makeup of people who are able to benefit the most from green tea polyphenols.
Effectiveness And Cost-effectiveness Of Systematic Screening For Lynch Syndrome (LS) In Australia

Summary
Lynch syndrome (LS) is an inherited condition that puts people at an increased risk of developing a range of cancers. We will use a detailed simulation model to evaluate the potential health benefits of testing new cases of colorectal, endometrial and ovarian cancers for LS, and whether this would be cost-effective. The aim is to identify LS-related cancer cases, so family members can be offered LS testing, and individuals found to have LS can be offered close observation/preventative surgery.

Summary
Diabetes, obesity, metabolic syndrome, hypertension and cancer are chronic diseases faced by many Australians. There is some evidence to suggest that those with diabetes or are obese are at an increased risk of cancer. Sufficiently large studies to examine these relationships do not exist in Australia. This project aims to pool Australian and New Zealand longitudinal studies which have information on diabetes and obesity to examine the relationship between diabetes, obesity and cancer.

Summary
The International Sarcoma Kindred Study (ISKS) aims to identify individuals who harbour germline TP53 mutations. TP53 mutations are characterised by the development of multiple cancers including sarcoma. This project will assess ISKS participants’ views of the feedback of genetic research information and will develop sensitive feedback practices. The acceptability and psychological impact of taking part in a pilot screening protocol designed for cancer-prone populations will also be assessed.

Chronic kidney disease (CKD) is an important public health problem in Australia and worldwide. Not only does CKD predisposes to end-stage kidney disease, but more importantly, increases the risk of co-morbidities such as cancer and cardiovascular disease, leading to premature death.

Summary
Vulvar cancer is a rare disease; in 1993-1997 the age-adjusted incidence rate in Australia was 1.4 per 100,000 women (average 207 cases per year), similar to the incidence in most other countries. An epidemic of cases of vulvar cancer has been identified in younger Indigenous women living in remote communities in the Northern Territory (NT). Vulvar cancer is over fifty times more common in women aged less than 50 years in these communities than in the total Australian population.

An epidemic of cases of vulvar cancer has been identified in younger Indigenous women living in remote communities in the Northern Territory (NT). Vulvar cancer is over fifty times more common in women aged less than 50 years in these communities than in the total Australian population. Women in these communities also experience higher rates of high-grade Vulvar Intraepithelial Neoplasia (a pre-cursor to vulvar cancer), than elsewhere in the NT. Vulvar cancer is usually much more common in older women than younger women. In young women vulvar cancer and VIN are thought to be caused by infection with cancer causing strains of human papillomavirus (HPV), particularly the strain known as HPV16. In older women, vulvar cancer is not caused by HPV. In the remote communities in the NT, vulvar cancer is occurring almost entirely in young women, the amount of cancer occurring in older women in these communities is similar to the amount expected in the total Australian population. This project will investigate the cause of this epidemic of vulvar cancer and high-grade VIN. It will investigate whether HPV16 is more prevalent in these communities than elsewhere in Australia; whether there is a variant strain of HPV16 in these communites that is more virulent at causing cancer, and whether the disease occurs more commonly in families, which would mean that women in these communities inherit an increased susceptibility to vulvar cancer and VIN. This project will help to increase our understanding of vulvar cancer and VIN, help to control this epidemic, and inform whether the new HPV vaccines may be effective in preventing vulvar cancer in these communities.Read moreRead less

Summary
There is good evidence that population screening for bowel cancer (CRC), based on the detection of blood in stools, is effective in reducing deaths from bowel cancer by around 30-40%. Screening depends on the use of a simple test to identify those who most need the complex and costly test which is capable of accurately detecting curable cancers and precancer lesions. This can be achieved with moderate effectiveness using simple tests (FOBTs) which detect microscopic amounts of blood in the faece ....There is good evidence that population screening for bowel cancer (CRC), based on the detection of blood in stools, is effective in reducing deaths from bowel cancer by around 30-40%. Screening depends on the use of a simple test to identify those who most need the complex and costly test which is capable of accurately detecting curable cancers and precancer lesions. This can be achieved with moderate effectiveness using simple tests (FOBTs) which detect microscopic amounts of blood in the faeces. If we are to reduce the rate of death from CRC, we must have an effective way of encouraging people to do these tests. While much has been learnt from experience with screening for breast and cervical cancer, CRC presents a series of quite different issues that have never been comprehensively studied. These are: (1) men and women need to be screened. (2) symptoms due to CRC are more complex , (3) the high-risk settings for CRC are much more complex), (4) the community is not as aware of the benefit of screening, (5) the initial test can be performed at personal convenience in one's home, (6) participants must handle bodily excretions, and (7) inconvenience of attending a central facility is avoided. We will survey participants and non-participants to more accurately identify the barriers to screening, and the proportion who have not participated for informed reasons. To test the real value of attempts to overcome these, we will then offer screening by various approaches designed to overcome these. We are in a unique position to do this as we have well-identified populations who have been offered faecal occult blood test (FOBT)-based screening These studies will assist in the design and implementation of effective screening programs for the early detection of CRC in Australia, which in the long term will significantly reduce deaths from this disease.Read moreRead less

The findings from this research will inform the development of public health policy on the most cost-effective utilisation of resources for preventing cervical, anogenital and head/neck cancers, and genital warts, in women and men, due to human papillomavirus (HPV). We will evaluate strategies for using emerging screening and vaccine technologies to prevent HPV-related disease, and assess potential adverse outcomes of vaccination. Men are currently not covered by routine vaccination or screening programs; this research will assess the benefit to men of vaccinating women only, and will consider the impact of vaccination and other interventions targeted towards men.Read moreRead less

Summary
Currently, only hepatitis B vaccine is routinely given at birth and for all other vaccines the earliest recommended administration is at 6 weeks old. This is too late to protect infants against pertussis and the most severe cases (hospitalisation or death) occur before 4 months. This research aims to assess if birth pertussis vaccination can protect infants earlier, measure the longevity of immunity following birth hepatitis B vaccination and examine the potential role for maternal vaccination

Summary
Eczema, food allergy, asthma and hay-fever are all common conditions that are a substantial burden for individuals and families. To prevent them, we need to know their causes, but these are not yet well understood. We need better studies to identify what is causing our children to develop these allergic diseases, and rigorous studies to prevent them. In this fellowship, I will explore the causes and consequences of these conditions and test ways to prevent children from developing them.
