Summary
Oesophageal cancer is a rapidly fatal disease which is becoming more common in Australia, the United States and other industrialised nations. This study will examine the mechanisms leading to the development of oesophageal cancer and aims to measure the effects of genes and environment on the burden of cancer. Ultimately, this research will help target persons at highest risk so that screening, prevention and surveillance efforts can be directed more effectively.
Novel Genetic And Environmental Modifiers Of The Risk Of Iron Overload-related Disease In HFE-associated Hereditary Haemochromatosis In Cohort Of Middle-aged Australians

Summary
People who carry mutations in the HFE gene are pre-disposed to body iron overload but not all of them developed subsequent disease. According to the investigators of the “HealthIron” study in Melbourne, only 28% of men and 1% of women with faulty HFE genes go on to develop disease. This study has recruited more than 1,000 people from the community, and will determine which environmental and genetic risk factors stop people with iron overload from getting symptoms of disease.
Genetic And Environmental Risk Factors For Colorectal Cancer: Anatomic Site Specificity

Summary
Cancer of the large bowel (colorectal cancer) is the second most common cancer in Australians and is becoming more common. Despite this, there is still much uncertainty about what causes some people to develop this cancer. We believe that some of this uncertainty arises because there are actually different causes of cancer for different sections of the colon and rectum. This study aims to collect information from 1000 people with colorectal cancer and 1000 people without colorectal cancer, and c ....Cancer of the large bowel (colorectal cancer) is the second most common cancer in Australians and is becoming more common. Despite this, there is still much uncertainty about what causes some people to develop this cancer. We believe that some of this uncertainty arises because there are actually different causes of cancer for different sections of the colon and rectum. This study aims to collect information from 1000 people with colorectal cancer and 1000 people without colorectal cancer, and compare various factors such as their genetic makeup, diet, AND lifestyle. We expect to find that some factors are more common in people with cancer in the upper parts of the bowel, while other factors are more common in people with cancer in the lower parts of the bowel. This kind of information can be used to design programs to prevent colorectal cancer. For example, we might advise people to exercise more or eat more fish in order to decrease their chances of developing this cancer.Read moreRead less
Predicting The Individual Risk Of Prostate Cancer In Australian Men

Summary
Prostate cancer is a major cause of disability and death in Australian men. A number of factors, particularly age and family history, influence the risk of prostate cancer but, in contrast to breast cancer, we don't know what is the risk of developing prostate cancer over a period of time for a man with a specific set of risk factors. In fact, while a number of statistical models have been developed that use a woman's risk factor profile to estimate her risk of breast cancer, none is currently a ....Prostate cancer is a major cause of disability and death in Australian men. A number of factors, particularly age and family history, influence the risk of prostate cancer but, in contrast to breast cancer, we don't know what is the risk of developing prostate cancer over a period of time for a man with a specific set of risk factors. In fact, while a number of statistical models have been developed that use a woman's risk factor profile to estimate her risk of breast cancer, none is currently available for prostate cancer. We will apply standard statistical methods to existing data from the Australian Risk Factors for Prostate Cancer study and from the Australian Institute of Health and Welfare to develop a prostate cancer risk prediction model. We will test how factor like age, detailed family history, diet, baldness status and possibly previous PSA tests and prostate biopsies predict the risk. After developing the model, we will test the accuracy of the predictions in three ways. First, using existing data from the Australian Prostate Cancer Family Study, we will see whether the number of cases in a group of men is close to the number predicted by the model (calibration). Second, to test whether the model discriminate well men who develop prostate cancer from those who do not, we will collect family trees in a sample from the Melbourne Collaborative Cohort Study. We will use these data also to estimate the optimal cut point: men above this level of risk will be considered at high risk. Third, we will apply the model to existing data from the Dutch Prostate Cancer Family Study (DPCFS) to test whether the optimal cut point identify high-risk men and to validate the model in a non-Australian population. Finally, we will prepare a computer package that health professionals will use as decision-making tool in different scenarios including individual cancer risk assessment, design of prevention trials and targeting prevention programs to high-risk men.Read moreRead less
Obesity, Pre-diabetes And Future Risk Of Diabetes: Maximising The Evidence, Minimising The Cost

Summary
The overarching aim of this proposal is to reliably determine how best to identify people at high risk of developing future diabetes. We will do this by using information on biological and behavioural risk factors that was collected on nearly 200,000 people many years ago and who were subsequently followed up to see who developed diabetes. This information will be used to create a risk prediction tool for spotting individuals most at risk of developing diabetes at some point in the future.
Automated Mammographic Measures That Predict Breast Cancer Risk

Summary
Mammographic density (MD) is one of the strongest predictors of breast cancer risk but its impractical measurement prevents its use in a clinical setting. An automated measure of MD would allow screening programs to identify and target women at higher risk of breast cancer which could lead to earlier diagnoses and better breast cancer outcomes. We aim to develop an automated measurement, maximized by its ability to predict breast cancer risk, and applicable to both film and digital mammograms.
Monitoring cardiovascular risk is a major part of the clinical workload both in general practice and specialty areas, but it is an under-researched area, reflected in a general lack of evidence based guidelines. My research will evaluate how to optimise the monitoring of cardiovascular risk both before and after starting treatment. By maximising clinical benefits for patients and minimising unnecessary resource use, my research will benefit patients, clinicians and the community at large.
The proportion of the population over 65 years of age is increasing, and cardiovascular disease (CVD) is a leading cause of disability and death in this group of people. Angina, heart failure and stroke in elderly people often result in considerable disability and in many instances in a need for changed living circumstances such as admission to nursing homes. Consequently there is an important need to understand how to prevent and manage cardiovascular diseases in elderly people.

Angina, heart failure and stroke in elderly people often result in considerable disability and in many instances in a need for changed living circumstances such as admission to nursing homes. Consequently there is an important need to understand how to prevent and manage cardiovascular diseases in elderly people. Although CVD occurs much more frequently in older persons, much of the epidemiological information on CVD risk factors and risk estimation comes from studies of middle-aged populations. Recently there has been an increased focus on whether the established relationships hold or differ in the elderly. This has generated debate about the relative value and effectiveness of treating risk factors in elderly people. This study, which is based on comprehensive and long-term risk factor, mortality and morbidity data from the Busselton Health Study and Health in Men Study, will lead to a better understanding of classic and new CVD risk factors in older persons and will contribute positively to the debate about the relative value and effectiveness of attempting to modify risk factors in the elderly. Further, it will facilitate improved methods for CVD risk assessment in older people and hence assist in determining whether which preventive actions to implement in the elderly.Read moreRead less
