The aim of the study is to clarify when is the optimal time to start hormone treatment for men with certain stages of prostate cancer. It has long been known that testosterone removal impedes prostate cancer growth, although not permanently. The removal of testosterone, however, has side effects , including loss of libido, hot flushes, weight gain, and in the longer term osteoporosis, loss of muscle bulk and mental changes such as loss of memory.

It has long been known that testosterone removal impedes prostate cancer growth, although not permanently. The removal of testosterone, however, has side effects , including loss of libido, hot flushes, weight gain, and in the longer term osteoporosis, loss of muscle bulk and mental changes such as loss of memory. Any benefit to be gained for a patient must therefore be weighed against these side effects. This is particularly relevant in situations in which cure is not possible, when the aim of treatment should be to manage symptoms (either by preventing or delaying them or treating them as they arise). There are two situations in which a man may be diagnosed as having active prostate cancer but be without symptoms requiring immediate treatment. The first is after the failure of curative treatment, shown by the presence of prostate specific antigen (PSA) in the blood, but without any other evidence of prostate cancer. The second is a man newly diagnosed with asymptomatic prostate cancer, but with other reasons (such as heart disease) which make an attempt at cure inappropriate. We do not know in either case whether or not men live longer if treatment is started immediately, or whether it is reasonable to wait until symptoms develop, thus potentially postponing the side effects of treatment. The trial will therefore include these two groups of men. Half the men will be randomised to receive immediate treatment, and half to treatment starting when symptoms develop, or when there is evidence of progressive disease. The main endpoint is overall survival, balanced against quality of life and side effects from the disease and treatment. The hypothesis is that early treatment will improve survival with acceptable effects on quality of life.Read moreRead less
New Generation of High-Performance Radio Frequency Devices . The strong demand for faster internet speed pushes high-speed technology to evolve faster. Designing and developing devices are now facing changes that are far more complex. We aim to tackle them, proposing to develop phase-change materials-based electronic systems. The outcomes will be reconfigurable devices with unprecedentedly increased operational frequency, reduced critical system-level metrics, and elimination of control circuits ....New Generation of High-Performance Radio Frequency Devices .

The outcomes will be reconfigurable devices with unprecedentedly increased operational frequency, reduced critical system-level metrics, and elimination of control circuits. The successful results will address the Science and Research Priority of Modern Manufacturing and bring substantial socio-economic benefits to Australia by executing advancements of new technologies for modern wireless communications, leading to new high-tech opportunities, jobs, and economic growth.Read moreRead less
MICROFABRICATED DEVICES: A SIGNIFICANT ADVANCE FOR THE DETECTION AND MOLECULAR ANALYSES OF CIRCULATING CANCER CELLS?

Summary
Using advanced microfabrication concepts, this project aims to develop a platform technology able to capture tumour cells circulating in the blood of cancer patients. Although present only in extremely small numbers, these cells provide invaluable insights into the pathophysiology of the disease and consequently provide vital diagnostic and prognostic information. Molecular analyses of these cancer cells could ultimately enable the design of improved and personalized cancer treatment.
