Leading radiation scientists developing innovative methods and devices for treating cancer patients will collaborate in future research using this highly adaptable linear accelerator for medical radiation research. Innovations in tumour targeting, better patient safety, new medical devices and improved cancer outcomes are expected.
Reducing The Greatest Uncertainty In Radiotherapy.

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.
A Randomised Phase III Study Of Radiation Doses And Fractionation Schedules In Non-low Risk DCIS Of The Breast

Summary
Treatment of ductal carcinoma in-situ (DCIS), a preinvasive form of breast cancer, is aimed at preventing invasive cancer recurrence. Women with higher-risk DCIS have an increased risk of recurrence. This study aims to individualise treatment for women with DCIS to achieve long-term tumour control with minimal treatment toxicity. After local excision of DCIS, radiotherapy (RT) to the whole breast reduces the recurrence rate. However, it is unclear if escalating radiation dose to the tumour bed i ....Treatment of ductal carcinoma in-situ (DCIS), a preinvasive form of breast cancer, is aimed at preventing invasive cancer recurrence. Women with higher-risk DCIS have an increased risk of recurrence. This study aims to individualise treatment for women with DCIS to achieve long-term tumour control with minimal treatment toxicity. After local excision of DCIS, radiotherapy (RT) to the whole breast reduces the recurrence rate. However, it is unclear if escalating radiation dose to the tumour bed in higher-risk women increases tumour control. It is also uncertain if giving fewer but larger radiation doses over 3-4 weeks would achieve the same tumour control as the standard 5-7 week course of RT to improve patient convenience and access to RT. Thus, this multicentre study of 610 women with higher-risk DCIS will investigate if adding a tumour bed radiation boost after whole breast RT improves tumour control, and the shorter RT course achieves the same tumour control as the standard longer course. Currently, the ability to predict the malignant potential of DCIS and RT toxicity is limited. This study will investigate if there are biological and genetic markers predictive of invasive recurrence and normal tissue toxicity in women with DCIS using state of the art technology. Women need to weigh up the likelihood of cancer control against adverse treatment effects to make an informed treatment decision. However, very little is known about the quality of life (QoL) consequences of the diagnosis and treatment of DCIS. In this study, the QoL, psychological distress, perceived risk of invasive cancer recurrence and perceived cosmetic outcomes of women with DCIS, will be assessed using a questionnaire of validated measures. This study will refine treatment for women with DCIS according to their risks of recurrence. It will significantly advance the understanding of the biology of DCIS and its psychological and QoL outcomes after treatment.Read moreRead less
Radiotherapy Treatment For Prostate Cancer - A Change In Practice Based On Direct Evidence For Targeting And Toxicity Effects Using Real Outcomes Data

Funding Amount
$555,129.00
Summary
Radiotherapy for prostate cancer treatment will be more effective when we have better knowledge of what patient anatomy needs to be targeted, and what needs to be avoided. This project will combine data collected during a large Australasian prostate cancer radiotherapy trial, ‘RADAR’, with data collected using new patient imaging methods to determine how patient anatomy impacts on the effectiveness of their treatment and the side-effects they experience.
A phenomenological approach to improve radioembolisation treatment of cancer. In recent years, radioembolisation for liver cancer has become an effective therapeutic option. However, it is likely that patients are being “under-treated” as doses remain based on results from external radiation therapy. This project will develop a phenomenological approach to radionuclide therapy to improve outcomes for cancer patients.
Biofocussed Prostate Cancer RadioTherapy (BiRT): A Personalised Approach To Delivering The Right Dose To The Right Place

Funding Amount
$753,565.00
Summary
We propose a new approach to treating prostate cancer with radiotherapy to move from the standard whole prostate treatment to a personalised treatment that varies radiation intensity throughout the prostate. We will mathematically combine features that influence radiotherapy effect from advanced imaging, clinical and biopsy information. This model will map out the radiotherapy dose required at each part of the prostate, to maximise killing of the cancer whilst minimising harm to normal tissue
