Cancer Radiotherapy 2020: Accounting For Tumour Deformation In Real Time To Improve Treatment Outcome

Summary
Tumours in lung and prostate cancer change shape during radiotherapy treatment. This is not accounted for in current care, compromising the therapeutic efficacy. We will develop the first radiotherapy system that can adjust the radiation beam in real time to follow the changing tumour shape. We will assess the performance of the system and quantify the clinical benefit. It is expected that clinical implementation of this technique will improve the cure rates and decrease the treatment toxicity.
A Computerised Treatment Planning System For Synchrotron Radiotherapy Trials At The Australian Synchrotron’s Imaging & Medical Beamline.

Summary
Microbeam Radiotherapy (MRT) using synchrotron-generated X-rays has shown tremendous promise in pre-clinical trials in tumour-bearing rodents, with remarkable sparing of normal tissue. Synchrotron MRT has the potential to radically alter the way radiotherapy is performed for human cancers. Every radiotherapy patient undergoes some form of computerised treatment planning before their treatment starts. We aim to test and implement a synchrotron Treatment Planning System, as an essential step in re ....Microbeam Radiotherapy (MRT) using synchrotron-generated X-rays has shown tremendous promise in pre-clinical trials in tumour-bearing rodents, with remarkable sparing of normal tissue.

Targeting Adaptive Mechanisms To Endoplasmic Reticulum Stress In Melanoma

Summary
Melanoma is a major Australian health problem, but there is no curative treatment once the disease spreads beyond the skin. We will study the role the response of melanoma cells to stress conditions of an organelle called endoplasmic reticulum in determining sensitivity of melanoma to killing induced by therapeutic drugs. If successful, this study will provide much needed new insights into the resistance of melanoma to treatment and point to new treatment approaches against the disease.
Mortality Among Opioid Dependent Persons In Pharmacotherapy, NSW 1985-2006

Summary
Heroin dependence is a long term condition associated with high rates of death, illness and injury. Death rates are much higher than the general Australian population and the causes of death include drug intoxication or overdose, trauma, suicide, complications from blood born viruses such as Hepatitis C and HIV-AIDS and other medical complications of a chaotic drug-using lifestyle. As a part of a harm minimisation approach to heroin dependence, maintenance opioid pharmacotherapies seek to stabil ....Heroin dependence is a long term condition associated with high rates of death, illness and injury. Death rates are much higher than the general Australian population and the causes of death include drug intoxication or overdose, trauma, suicide, complications from blood born viruses such as Hepatitis C and HIV-AIDS and other medical complications of a chaotic drug-using lifestyle. As a part of a harm minimisation approach to heroin dependence, maintenance opioid pharmacotherapies seek to stabilise a chaotic heroin-using lifestyle by providing a regular dose of a legal, high quality opioid under medical supervision. Maintenance treatment uses long-acting opioids such as methadone and buprenorphine to provide consistent blood opioid levels so the client avoids the constant and disruptive cycles of opioid intoxication and withdrawal. Clients in regular maintenance treatments have lower death rates than untreated heroin dependent people and better outcomes with regards to drug use. However, death still occurs in methadone and buprenorphine treatment and minimising death rates is an important goal of treatment programs. This is a large longitudinal study looking at all NSW methadone and buprenorphine clients between 1985 and 2006, an estimated 44,000 people. In particular, the study looks at their mortality. It is a data linkage project, in that it uses two existing databases (a treatment database and a mortality database) and combines the information for each subject to get a better picture of how long methadone and buprenorphine clients survive, how much maintenance treatment they have received, and what the clients die of. This is the first time the mortality of all NSW methadone and buprenorphine recipients will be examined in a systematic way. It will allow us to compare the mortality of subjects receiving methadone and buprenorphine treatments and look at changes in mortality rates and causes of death over time. This will be an important policy resource.Read moreRead less
Targeting the host lipid environment to disrupt malaria transmission. This project aims to characterise host molecules (in particular lipids) that are crucial for the transition of malaria parasites from one host to another. Malaria parasites encounter different environments upon their transition from human to the mosquito host. This project expects to generate new knowledge on physiological changes that are triggered by particular differences in micronutrient abundance that allow the parasites ....Targeting the host lipid environment to disrupt malaria transmission. This project aims to characterise host molecules (in particular lipids) that are crucial for the transition of malaria parasites from one host to another. Malaria parasites encounter different environments upon their transition from human to the mosquito host. This project expects to generate new knowledge on physiological changes that are triggered by particular differences in micronutrient abundance that allow the parasites to survive in the new host. Anticipated outcomes include the identification of new intervention strategies and improved transmission model systems for vector-borne diseases. This gained knowledge could provide benefits to future biomedical applications by informing diagnostics or treatment of lipid associated diseases.Read moreRead less
