Inherited determinants of cancer aetiology. Family history of cancer is a strong risk factor for many cancers. This project will aim to identify inherited factors influencing risk of developing cancer and those factors influencing the course of the disease and outcomes.
DNA methylation-based diagnosis of cancer and identification of novel therapeutic targets. In our aging society, cancer represents a severe economic and quality-of-life threat. DNA methylation switches genes off, and recently, it was shown that defects in DNA methylation contribute to human diseases including cancer.

In our aging society, cancer represents a severe economic and quality-of-life threat. DNA methylation switches genes off, and recently, it was shown that defects in DNA methylation contribute to human diseases including cancer. This project will identify defects in DNA methylation associated with cancer. Identifying these defects will enable us to design non-invasive, early diagnostic tests for cancer on blood or bodily excretions, and to pursue novel therapeutic approaches for treating cancer. The expected outcomes would generate exports to markets in the USA and Europe and replace imports of drugs and technology to treat cancer.Read moreRead less

Summary
The induction of apoptosis, or programmed cell death, is a key factor in the response of tumours to chemotherapeutic agents and ionising radiation; therefore biological markers that predict the clinical outcome to these therapies are needed. Over the past 2 years, our laboratory has developed techniques of protein analysis to evaluate changes in proteins during apoptosis caused by chemotherapeutic agents.

Over the past 2 years, our laboratory has developed techniques of protein analysis to evaluate changes in proteins during apoptosis caused by chemotherapeutic agents. Preliminary protein profiling studies of apoptosis induction in human breast cancer cell lines showed time-dependent decreases in two proteins, identified as S100A6 and ubiquitin. Both are known to be important in cell function. In the proposed project we will build on our preliminary findings to provide important new information central to the understanding of cancer cell biology and apoptosis in addition to evaluating the ability of anti-cancer treatments to induce apoptosis. Using a combination of protein analysis technologies, this project has the potential to provide reliable and novel biomarkers which will indicate the efficacy and selectivity of anti-cancer treatments in inducing tumour cell death. The knowledge gained in this project will aid clinical assessment of the response to cancer treatment(s) in patients in the form of specific screening assays, and may result in identification and development of effective new agents for cancer treatment and prevention. Furthermore, the outcomes of this project will increase our understanding of fundamental cancer cell biology and apoptosis.Read moreRead less
mTOR signalling in serous ovarian cancer. Serous ovarian cancer is the most aggressive and lethal gynaecological cancer in Australian women. Activation of Mammalian Target of Rapamycin (mTOR) is frequently observed and associated with poor prognosis in ovarian cancer patients. However, the mechanisms dysregulating mTOR in the pathogenesis of ovarian cancer are unknown. In preliminary studies, deletion of genes regulating mTOR signalling in up to 60 per cent of human serous ovarian cancer patien ....mTOR signalling in serous ovarian cancer. Serous ovarian cancer is the most aggressive and lethal gynaecological cancer in Australian women. Activation of Mammalian Target of Rapamycin (mTOR) is frequently observed and associated with poor prognosis in ovarian cancer patients. However, the mechanisms dysregulating mTOR in the pathogenesis of ovarian cancer are unknown. In preliminary studies, deletion of genes regulating mTOR signalling in up to 60 per cent of human serous ovarian cancer patients was observed. This project will provide mechanistic details of involvement of mTOR signalling in pathogenesis of the serous ovarian carcinoma, and develop a rationale for targeting mTOR pathway in these patients.

Summary
The LACE study is a clinical trial comparing two types of surgery for women with early-stage cancer of the inner lining of the uterus, known as endometrial cancer. Treatment for endometrial cancer involves removal of the uterus, tubes, ovaries and lymph nodes. Traditionally this has been performed by open surgery via an abdominal incision.

Treatment for endometrial cancer involves removal of the uterus, tubes, ovaries and lymph nodes. Traditionally this has been performed by open surgery via an abdominal incision. Open surgery is effective for endometrial cancer, but it is highly invasive, resulting in visible scarring, tissue damage, blood loss and a fairly high risk of complications. Laparoscopic surgery, commonly referred to as keyhole surgery, is a new approach to removing the uterus, tubes, ovaries and lymph nodes. Preliminary results from this less invasive surgery have been extremely encouraging. Laparoscopic surgery is practical and safe in treating endometrial cancer, while also resulting in less tissue damage, lower blood loss, less pain and a shorter recovery period in hospital. The LACE study aims to give definitive answers about the results offered by laparoscopic surgery in treating women with early stage endometrial cancer. The primary aim is to investigate whether the treatment of endometrial cancer using laparoscopic surgery is as good as that using open surgery. Secondary aims look at whether laparoscopic surgery provides more benefits compared to open surgery for endometrial cancer, such as: - improvements in the quality of life post-surgery, - reduced number of early and late surgery-related complications, - shorter stays in hospital, - fewer blood transfusions required, - less pain post-surgery, and hence fewer pain-killers. The LACE study is already under way, with recruitment on target for Stage 1. This application seeks funding for Stage 2, to expand recruitment from 2007. The outcomes of the trial will have a significant bearing on the future choice of treatment for endometrial cancer. Therefore the study will impact many patients around the world, including ~2000 women every year in Australia.Read moreRead less

Summary
When treating patients diagnosed with cancer, nerve dysfunction is a common complication of chemotherapy, particularly with oxaliplatin. Neurological symptoms develop in up to 90% of patients following oxaliplatin treatment. Neurotoxicity is a key factor in determining the dosage and frequency of current chemotherapeutic agants. Oxaliplatin therapy results in disabling neurological effects. Onset of neuropathy can be relatively fast or in other cases may develop months after therapy has been com ....When treating patients diagnosed with cancer, nerve dysfunction is a common complication of chemotherapy, particularly with oxaliplatin. Neurological symptoms develop in up to 90% of patients following oxaliplatin treatment. Neurotoxicity is a key factor in determining the dosage and frequency of current chemotherapeutic agants. Oxaliplatin therapy results in disabling neurological effects. Onset of neuropathy can be relatively fast or in other cases may develop months after therapy has been completed. The other chief problems encountered during chemotherapy can be overcome: nausea and vomiting can be treated; myelosuppression can be reversed. End organ toxicity such as neuropathy cannot be controlled. Despite the high incidence of neuropathy due to chemotherapy, the mechanisms involved remain poorly understood, particularly with newer therapies. The aim of the present study is to measure nerve function in oncology patients treated with oxaliplatin using a novel protocol, attempting ultimately to identify aspects of dysfunction that correlate with clinical abnormalities, so helping to pin-point the mechanisms responsible for neuropathy. Once identified, management strategies can be developed to better target the prevention and treatment of neuropathy in oncology patients treated with chemotherapy.Read moreRead less
