Summary
Neuroblastoma is the most common solid tumour of early childhood. The proposed project will identify gene variations as well as birth characteristics and perinatal factors associated with the cause of neuroblastoma. Understanding the genetic causes of the disease can potentially identify genetic targets for treatment and improve diagnosis, while the identification of risk factors can be translated into interventions for prevention of neuroblastoma.
Sun Exposure, Vitamin D And The Outcome Of Prostate Cancer.

Summary
We will find out whether hours of sun exposure, reported in a standard interview by men with prostate cancer, reduces prostate cancer recurrence and progression. For any effect of sun exposure ithat we observe, we will find out whether it works through vitamin D, which is produced by sunshine on the skin, or is affected by changes in the vitamin D receptor gene, which produces the protein the binds with vitamin D on cells and makes it work. Prostate cancer is the most common cancer in men in Aus ....We will find out whether hours of sun exposure, reported in a standard interview by men with prostate cancer, reduces prostate cancer recurrence and progression. For any effect of sun exposure ithat we observe, we will find out whether it works through vitamin D, which is produced by sunshine on the skin, or is affected by changes in the vitamin D receptor gene, which produces the protein the binds with vitamin D on cells and makes it work. Prostate cancer is the most common cancer in men in Australia, and this study, using two of the largest collections of clinical outcomes data for this disease, will inform researchers, clinicians and consumers about the possible benefits of sun exposure and Vitamin D in the prevention of recurrence or progression of prostate cancer. On present evidence, these effects are very plausible possibilities. It may also identify sub-groups of men in whom sun exposure or vitamin D might be particularly beneficial in improving outcome of prostate cancer.Read moreRead less
Analysis Of Gene Amplification-loss And Methylation Associated With Progression To Metastatic Colorectal Cancer

Summary
Many bowel cancers can be removed by surgery, but in many cases the cancer reoccurs. While chemotherapy can reduce the chance of recurrence, it can produce significant side effects. Currently there are few markers to indicate change of recurrence, therefore deciding who should, or should not receive chemotherapy is difficult to decide. This study will analyse differences in DNA from patients that do and do not relapse, to guide future decisions on patients who will benefit from chemotherapy.

Summary
Using pools of DNA samples we will conduct a genome-wide association study for melanoma predisposition genes. The most promising candidate genes will be followed up by sequencing and further geneotyping of additional SNPs in order to identify the causal variants.

Summary
Colorectal and breast cancers are the two most common registrable cancers in Australia and are second only to lung cancer in the total number of cancer deaths each year (4,678 and 2,612 deaths in 1997 for colorectal and breast, respectively). Ovarian cancer kills a further 740 women each year (Source: Cancer in Australia 1997, AIHW and AACR 2000). Thus, on average, one Australian dies of colorectal, breast or ovarian cancer every hour! Clearly, these are major diseases with a significant impact ....Colorectal and breast cancers are the two most common registrable cancers in Australia and are second only to lung cancer in the total number of cancer deaths each year (4,678 and 2,612 deaths in 1997 for colorectal and breast, respectively). Ovarian cancer kills a further 740 women each year (Source: Cancer in Australia 1997, AIHW and AACR 2000). Thus, on average, one Australian dies of colorectal, breast or ovarian cancer every hour! Clearly, these are major diseases with a significant impact on our society. Unfortunately, though, we still do not understand the basic molecular and-or biochemical abnormalities that initiate and-or drive the development of these cancers. Recent functional and genetic studies in a number of different tumour types (including colon and ovarian) have suggested that members of the phosphatidylinositol 3-kinase (PI3K) enzyme family may be oncogenes (cancer-causing genes). However, strong evidence confirming a causal role for PI3K in human cancer is yet to be reported. Our research proposal outlines a study to address this issue. We have preliminary data demonstrating mutations in at least one member of this enzyme family in a number of tumours. We now propose to undertake a comprehensive analysis of the spectrum, and frequency, of PI3K mutations that occur in colon, breast and ovarian tumours. These studies will allow us to make a definitive assessment of the role of PI3K in the development human cancer. In addition to furthering our understanding of the processes involved in the initiation and progression of human tumours, this project also has the potential to identify new markers for the early detection of cancer and novel targets for new anti-cancer therapies.Read moreRead less
