Prognostic Significance Of Circulating Tumour Biomarkers In Patients Treated With Curative-intent Radiotherapy For NSCLC

Funding Amount
$877,098.00
Summary
More than 50% of cancer patients in Australia receive radiotherapy but many later die from distant metastases. This study of circulating biomarkers (tumour cells and DNA in the bloodstream) builds on evidence from research at Peter Mac showing that some lung cancers might spread during treatment with radiotherapy that would otherwise be curative. This study will help identify cancer patients at high risk of secondary cancers and could allow us to modify treatments to prevent them.

Summary
While surgery to remove gastric (stomach) cancer has been traditionally accepted as the only way to potentially cure the disease, there have been several recent advances using chemotherapy and/or radiotherapy both before and after surgery. However doctors' opinions remain divided regarding the best treatments to give and in what order. This randomised clinical trial will address the important question of whether combined chemotherapy plus radiotherapy is more effective than chemotherapy alone in ....While surgery to remove gastric (stomach) cancer has been traditionally accepted as the only way to potentially cure the disease, there have been several recent advances using chemotherapy and/or radiotherapy both before and after surgery. However doctors' opinions remain divided regarding the best treatments to give and in what order. This randomised clinical trial will address the important question of whether combined chemotherapy plus radiotherapy is more effective than chemotherapy alone in improving cure rates for stomach cancer.Read moreRead less
First Ever System To Continuously And Directly Measure The Internal Anatomy To Guide Breast Cancer Radiation Treatment Under Deep Inspiration Breath Hold
Funder

Funding Amount
$409,766.00
Summary
We propose a first ever system to continuously and directly measure the internal anatomy of the patient during radiotherapy of left sided breast cancer to ensure correct position of patient and radiation beam. The proposed method involves no additional radiation dose to the patient. It relies on existing components of modern radiation treatment machines, requiring no additional equipment, which will make it easy to implement widely.
Reducing The Greatest Uncertainty In Radiotherapy.

Funding Amount
$594,197.00
Summary
The weakest link in radiotherapy is defining treatment volumes (contouring). Lack of accuracy and consistency in clinical trial contouring has been shown to result in reduced patient outcomes. Manual review of contouring is resource intensive, expensive and for advanced treatments unachievable in a timely fashion. We will assess an automated approach to contouring assessment using 4 clinical trial datasets, changing practice for future studies and enabling consistent assessment in the clinic.
Very Fast, Accurate And Low Dose Imaging For Radiotherapy Treatments

Funding Amount
$650,651.00
Summary
This project will reduce scan times and imaging dose by an order of magnitude for an imaging modality that is the standard of care for lung cancer patients receiving radiotherapy. Specifically, scan times reduce from 4min to below 60sec, image quality will be improved and imaging dose will be reduced by 85%. These improvements not only improve treatment efficacy by improving the accuracy of radiotherapy delivery, they reduce treatment times and reduce discomfort to the patient.
Translating Synchrotron Microbeam Radiation Therapy Into A Clinical Reality For Cancer Patients

Summary
The aim of this project is to translate an experimental radiotherapy technique, known as microbeam radiotherapy, into a clinical reality for the benefit of cancer patients world-wide. I propose to achieve this aim by working at the European Synchrotron Radiation Facility (ESRF) in France. The ESRF is Europe’s most powerful synchrotron light source, where a multi-disciplinary team of scientists and physicians are collaborating to treat the first human cancer patients with synchrotron radiation.
Stereotactic Body Radiotherapy (SBRT) As A New Standard Of Care For Spinal Metastases
Funder

Funding Amount
$200,148.00
Summary
Secondary spread of cancer to the spine affects about 40% of all cancer patients. The current standard of care, radiotherapy, does not provide durable control of cancer pain. Breakthrough technology in stereotactic body radiotherapy (SBRT) is showing considerable promise for improved patient outcomes. This study is a multi-national collaboration between Australia and Canada directly comparing conventional radiotherapy to spinal SBRT in order to establish spinal SBRT as the new standard of care.
The proposed project is part of a research programme aimed at developing a new drug to reduce the side effects of cancer radiotherapy. These side effects result from the radiation damage to normal tissues close to the tumour. Since in many instances the normal tissues at risk are accessible to topical application (eg. skin in breast cancer patients, rectal mucosa in prostate cancer patients, oral mucosa in all patients being treated for tumours in the head and neck region) the concept is very si ....The proposed project is part of a research programme aimed at developing a new drug to reduce the side effects of cancer radiotherapy. These side effects result from the radiation damage to normal tissues close to the tumour. Since in many instances the normal tissues at risk are accessible to topical application (eg. skin in breast cancer patients, rectal mucosa in prostate cancer patients, oral mucosa in all patients being treated for tumours in the head and neck region) the concept is very simple. A drug which makes cells less sensitive to X-rays (these drugs are called radioprotectors) is simply applied topically to the normal tissues at risk. For this purpose, we have developed a new radioprotecting drug called methylproamine which is 100-fold more potent than previously-developed radioprotectors. Unfortunately, methylproamine is not suitable for our purpose because at higher concentrations it is toxic to some cells. This hurdle must be overcome in order to make the project attractive to potential commercial sponsors. Our aim is to modify methylproamine by removing the molecular features that cause the cytotoxicity. We have established that this is feasible, by synthesising and evaluating a small family of methylproamine analogues. Some less toxic family members have already been identified. With this knowledge, we now propose to use special computer programmes to design a much larger family of methylproamine analogues, and to synthesise and test each one in order to identify the most promising candidate for our purpose. Once the efficacy window hurdle is passed, the subsequent milestones to commercialisation and clinical implementation can be addressed, with appropriate sponsorship. An Australian company has already expressed strong interest and is evaluating the opportunity.Read moreRead less

Summary
Aim 1 is to document the pathological, surgical, radiotherapy and chemotherapy patterns of care in the Australian setting using the AGOG (Australian Genomics and Clinical Outcomes of Glioma) database. The second aim to develop non-invasive imaging biomarkers which can be used to monitor treatment efficacy. The third aim is to improve outcomes using drug and radiation combination therapy. in the treatment of high grade gliomas.
Cancer Radiotherapy 2020: Accounting For Tumour Deformation In Real Time To Improve Treatment Outcome
Funder
National Health and Medical Research Council
Funding Amount
$371,616.00
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.
