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
Preparing Cancer Patients For Clinical Decision Making: A Randomised Trial Of Preconsultation Preparation Packages.

Summary
Most cancer patients in Australia now expect and are told their cancer diagnosis. There is considerable variation in the extent to which patients are informed about treatment options and are involved in treatment decisions. It can be argued that a treatment decision should be based on the oncologist's knowledge and the patient's preference. Two possible models can achieve this optimal outcome: the oncologist decides treatment on the basis of information passed on to him-her from the patient (the ....Most cancer patients in Australia now expect and are told their cancer diagnosis. There is considerable variation in the extent to which patients are informed about treatment options and are involved in treatment decisions. It can be argued that a treatment decision should be based on the oncologist's knowledge and the patient's preference. Two possible models can achieve this optimal outcome: the oncologist decides treatment on the basis of information passed on to him-her from the patient (the enabled doctor), and the patient chooses treatment based on informaton provided by the doctor (the empowered patient). We have developed a booklet on 'how treatment decisions are made'. In a randomised trial, patients seeing an oncologist for the first time are given the booklet and shown a video of ' their' oncologist interviewing an actor patient. The subsequent consultation is audiotaped to study the effect of these interventions on patient and doctor behaviour. The results of this trial will inform the development of our new patient educational materials. We now plan to develop consultation preparation packages. Patients will be sent information at least 48 hours before their first appointment with an oncologist with the goal of helping patients to achieve their preferred involvement in the consultation. The complete package will contain four components : a booklet on how treatment decisions are made including an outline of the two treatment decision models, a question prompt sheet and recommendation to prepare a list of questions, a booklet on Patient Rights, and an introduction to the Cancer Centre. The effects of the total package, and of just the Cancer Centre component on patient preferences for information and involvement in medical decisions, their consultation behaviour, and patient and doctor satisfaction with decision making will be studied in a randomised trial with control patients receiving no preparatory materials.Read moreRead less
A La CaRT: Australasian Laparoscopic Cancer Of The Rectum Trial. A Phase III Prospective Randomised Trial Comparing Laparoscopic-assisted Resection Versus Open Resection For Rectal Cancer

Summary
The major treatment for rectal cancer is surgical removal of tumour with a large cut through the abdomen. There is a newer, less invasive procedure known as laparoscopic resection which enables the same surgery to be performed using a scope inserted in the abdomen and another smaller incision for removal of the tumour. This study is being conducted to determine whether the newer procedure is as safe and effective as the current procedure. Patients on the trial will be given either laparoscopi
Targeting Prostate Cancer And Metastases With Novel Anti-tumour Drugs.

Summary
Prostate cancer is highly aggressive, causing one death every 4 minutes. It is the most common tumour and is the second highest cause of cancer death in men in Western society. Once it escapes the prostate and spreads to other parts of the body it cannot be cured. Current treatment options are limited and cause debilitating side effects. In this study I will investigate a new class of anticancer drugs developed in my host laboratory for prostate cancer treatment.
Prospective Ovarian Cancer Cohort To Authenticate Stratification Of Prognosis In Ovarian Tumours (POCCA-SPOT)

Summary
Ovarian cancer has poor survival, with less than 40% of women surviving 5 years. There is a wide range of survival, but very few characteristics that indicate which patients will do well or poorly. We have developed a tumour test at diagnosis, that can predict prognosis at 5 years. In newly diagnosed cases, we will test tumours to predict prognosis and then determine the accuracy and assess patient acceptability. This study will lead to clinical use of the test and improve treatment decisions.
This project aims to comprehensively evaluate the role of androgen receptor (AR) signalling in breast cancer by identifying changes in AR signalling and its role in an endocrine resistant setting. Understanding the changes in AR signalling in either treatment-naive or treatment-resistant context would better assist in the identification for opportunities to modulate AR signalling as a therapeutic target in breast cancer.
Indwelling Pleural Catheter For Management Of Cancer-related Pleural Effusions

Summary
Most cancers can be complicated by fluid accumulation (effusion) in the (pleural) cavity between the lung and chest wall, causing significant breathlessness. Indwelling pleural catheter (IPC) is a new method that allows patients to drain the effusion outside the hospital and avoid further invasive interventions. This study aims to provide important information that will help guide use of IPC and manage its complications, especially infection, improve patient outcomes and save healthcare costs.

Summary
My approach and ultimate goal over the next 4 years is to demonstrate the use of recently discovered “Nanoshearing” technology as a standard diagnostic tool for cancer patients undergoing systemic therapy and assess the impact of standard protocols in predicting response to therapy and patient outcomes. Data from this study could potentially define new standards of clinical practice, as they relate to follow-up screening for response to therapy and recurrence of disease.

Summary
The next generation of medical diagnostics and discovery in disease research will involve the marriage of PCR, a tool used to amplify large amounts of DNA from small starting quantities, and �next generation� sequencing, a way to sequence lots and lots of DNA on a single instrument run. This study aims to describe methods which allow scientists to screen hundreds of disease genes in hundreds of people simultaneously with high accuracy and high efficiency.
ALT-associated PML Bodies: Keys To The Biology And Treatment Of An Important Subset Of Cancers

Funding Amount
$813,614.00
Summary
Alternative Lengthening of Telomeres (ALT) is a molecular mechanism used by ~10% of cancers to sustain their relentless growth. ALT is common in sarcomas and brain tumours which are difficult to treat. ALT cancers contain nuclear structures called ALT-associated PML nuclear bodies (APBs) which may be part of the ALT machinery. This research will investigate characteristics of APBs and how they are formed, and will use this information to identify drugs to treat ALT tumours.
