Summary
Prostate cancer depends for its growth on the male hormone, testosterone, which circulates in the blood. As a result treatment which reduces testosterone level ('androgen deprivation'[AD] therapy) can produce clinically important shrinkage of prostate cancer. Each year approximately 4000 men in Australia and New Zealand develop prostate cancer which has not spread widely and which is amenable to attempted cure by surgery or radiation.

As a result treatment which reduces testosterone level ('androgen deprivation'[AD] therapy) can produce clinically important shrinkage of prostate cancer. Each year approximately 4000 men in Australia and New Zealand develop prostate cancer which has not spread widely and which is amenable to attempted cure by surgery or radiation. Results from recent trials, including a large trial run in Australia and New Zealand by the Trans-Tasman Radiation Oncology Group (TROG) between 1996 and 2000, suggest that 6 months AD will benefit many of these men if administered in conjunction with radiotherapy.The aim of this project is to run a further trial to find out whether 12 months of AD, after radiotherapy will prevent the need for further treatment and prolong more lives than only 6 months AD. Bisphosphonate treatment also offers important benefits to prostate cancer patients because it can increase bony stregth by increasing its density and can also arrest cancerous growth in bones. A further aim of the trial therefore is to determine whether 18 months of bisphosphonate therapy (BP) will prevent bone loss (osteoporosis) caused by AD, and also further reduce the risk of secondary bone cancer developing. This trial will involve recruitment of 1000 men across Australia and New Zealand over a 5 year period. When complete the trial will determine whether further treatment can be delayed and life prolonged in up to half of all men in whom treatment presently fails. This grant will support collection of patient data and the necessary quality checks to ensure that reliable conclusions can be drawn.Read moreRead less
Bisphosphonate Treatment Of Childhood Femoral Head Avascular Necrosis Due To Perthes Disease

Summary
Perthes disease (PD) occurs following loss of blood supply to the hip (femoral head). It is a severe childhood disorder with over 250 new cases per year in Australia. PD results in flattening of the normally round femoral head and painful arthritis. The hip becomes flat because the bone is eaten by cells called osteoclasts. We will test if a medicine aimed at stopping these osteoclasts can prevent hip flattening. This should decrease the risk of arthritis and the need for hip replacement.
Development And Pre-clinical Evaluation Of A Novel Wound Dressing Treatment For Chronic Ulcers

Summary
Chronic leg ulcers are a common, painful and costly reality for many Australians, impacting on sufferers' mobility, social interactions and overall quality of life. This research is directed at developing a novel cost-effective wound dressing for treatment of this condition. This will be achieved through neutralising the ulcer's toxic proteolytic environment through an interactive wound dressing. This then will allow the body's own cells to promote wound healing.
