Summary
Melanoma is a major Australian health problem. It is the third most common cancer in men and women and has a disproportionately heavy impact on productive years of life because it is the common cause of cancer death in younger adults. The investigators are all associated with the Melanoma Institute Australia, incorporating the Sydney Melanoma Unit (SMU).

It is the third most common cancer in men and women and has a disproportionately heavy impact on productive years of life because it is the common cause of cancer death in younger adults. The investigators are all associated with the Melanoma Institute Australia, incorporating the Sydney Melanoma Unit (SMU). MIA is the world’s largest clinical service dedicated to the treatment of melanoma, treating >1500 new melanoma patients annually and maintains a repository of clinical data on melanoma and a large melanoma tissue bank. The Program has also recruited large numbers of people from the community, as well as people with a strong family history of melanoma, in order to study its causes. It aims to utilise these internationally-recognised resources to develop a scientific basis for 1) improved management of individuals at high risk for development and progression of melanoma, and 2) improved treatment of patients with early and disseminated melanoma, in an era of rapid change in the prospects of successfully treating this dangerous cancer. The Program will do this by consolidating and extending its existing collaborative research, supported by NHMRC since 2006.Read moreRead less

Summary
Anti-inflammatory drugs (sometimes called NSAIDs) are widely used in the treatment of arthritis and also as general purpose pain killers. Up to 10 million prescriptions are written each year for these drugs in Australia. Some of the older versions of these drugs like ibuprofen (eg Brufen) and naproxen (trade name Naproxen) cause side effects which can be serious. Damage to the stomach is a particular problem and this can lead to serious bleeding or perforation of ulcers.

Up to 10 million prescriptions are written each year for these drugs in Australia. Some of the older versions of these drugs like ibuprofen (eg Brufen) and naproxen (trade name Naproxen) cause side effects which can be serious. Damage to the stomach is a particular problem and this can lead to serious bleeding or perforation of ulcers. Less well recognized are the adverse effects of these drugs on the heart and the kidneys. The older fashioned members of this class of drug are rapidly being replaced by newer agents known as COX-2 inhibitors. Popular examples in Australia are celecoxib (trade name Celebrex) and rofecoxib (trade name Vioxx). These drugs are heavily promoted as being safer than the older NSAIDs. In the case of the stomach, this claim seems to be correct. However, the effects of the new COX-2 inhibitors on the circulation have not been fully assessed. Recently, claims have been made that these drugs may increase the risk of heart attacks. If this were true, it would be an effect that was unique to COX-2 inhibitors as it has not been reported with the older NSAIDs. We plan to carry out a 3 year study in Newcastle hospitals in which we compare the use of COX-2 inhibitors in a group of patients admitted to hospital with a heart attack or unstable angina with that of a control group of patients who were admitted to hospital around the same time, but not for heart problems. We are interested in whether COX-2 inhibitors are associated with an increased risk of heart attacks and whether use of small doses of aspirin protects against this effect. Depending on the results we may be able to improve the safety of these drugs in patients at risk of heart attacks.Read moreRead less

Summary
Non-steroid anti-inflammatory drugs (NSAIDs) have pain-killing and anti-inflammatory properties. For many years Australia had a higher use of these drugs than other countries. The drugs are quite toxic, and in susceptible individuals may cause ulceration and bleeding from the stomach and duodenum, kidney damage and fluid congestion leading to heart failure. Each of these conditions carries a high morbidity, particularly in the elderly. Because of concerns about toxicity, the use of NSAIDs in Aus ....Non-steroid anti-inflammatory drugs (NSAIDs) have pain-killing and anti-inflammatory properties. For many years Australia had a higher use of these drugs than other countries. The drugs are quite toxic, and in susceptible individuals may cause ulceration and bleeding from the stomach and duodenum, kidney damage and fluid congestion leading to heart failure. Each of these conditions carries a high morbidity, particularly in the elderly. Because of concerns about toxicity, the use of NSAIDs in Australia fell during the 1990s by around 40%. Newer allegedly safer forms of NSAIDs called COX-2 inhibitors have been introduced into the Australian market. The first 2 drugs to be marketed are called Celebrex and Vioxx. These drugs appear to be safer for the stomach and duodenum, but the true effects on the kidney and heart are as yet unclear. COX-2 inhibitors have been very widely used with over 1.7 million prescriptions issued since their listing on the Pharmaceutical Benefits Scheme in August 2000. Most of this use appears to be in addition to prescribing of the older NSAIDs rather than as a replacement for them. The purpose of this study is to compare the safety of the new COX-2 inhibitors with that of the older NSAIDs. We are interested in how often they cause renal failure and heart failure. The investigators will use well-established research methods to estimate the risk of heart failure and kidney failure with these drugs in the Australian community. Data from the study will form the basis of clinical practice guidelines for the safe use of these drugs in Australia.Read moreRead less

Summary
Multiple sclerosis is the second most common cause of neurological morbidity in young Australians after trauma. Knowing who will progress to develop multiple sclerosis after a first attack and at what rate they will progress is an important question as it will allow us to target treatment to those at greatest risk and modify a person's lifestyle to reduce the risk of developing MS or slow their rate of progression.

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.
A Vulvar Cancer Cluster In Young Indigenous Women In Arnhem Land: Investigation Of Community Knowledge, Genetic Susceptibility And Supportive Care Response

Summary
Cancer of the vulva is 50 times more common in young Aboriginal women in Arnhem Land than in other women. Human Papillomavirus (HPV), which also causes cervical cancer, is the usual cause of this cancer; initial investigations have found that HPV is present in these cancers but is not the reason for the excessive incidence. This study will investigate local knowledge about this disease, and whether inherited susceptibility or an environmental cancer-causing substance are the cause of the excess.

Summary
We have found mutations in DNA repair genes in AML patients, and associated the presence of these with increased risk of developing AML. Our hypothesis is that the presence of these mutations leads to reduced efficiency of DNA repair, and increased risk of additional mutations and leukaemic transformation. Our aim is therefore to determine the changes associated with these mutations in blood cell precursors, and to investigate the potential of targeted therapies for this group of patients.
Neuroblastoma (NB) is a common cancer in children, and one of the hardest to cure. Some mature into a benign tumour without needing any treatment, others are aggressive and require intensive treatment, and some regrow despite all treatment. It is often difficult to predict accurately how NBs will behave. We will study the two ways NBs can undergo unlimited growth, to determine whether this predicts tumour behavior, and therefore what treatment is needed.
