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.

Summary
Microbeam Radiation Therapy (MRT) is an emerging X-ray radiosurgery modality that offers new hope for the treatment of brain cancer and other human brain diseases. A tissue equivalent radiation dosimetry system is essential for upcoming MRT human trials to precisely verify treatment plans. We are recognized world leaders in real-time silicon detector instrumentation for radiation dosimetry. We plan to develop and demonstrate X-RATE, the X-ray Real-time Active Tissue Equivalent dosimeter.

Summary
BrachyVision is an in-body imaging and dosimetry system to assist physicians in providing efficient and optimized permanent seed implant brachytherapy cancer treatment. The system allows intra-operative preplanning, image guided treatment, post implant verification and direct rectal dosimetry. It represents a major advance in clinical technology that can improve quality of life of prostate cancer patients and, through reduced post treatment complications, lead to significant health cost savings.
REVEALING MOLECULAR MECHANISMS OF THE SYNCHROTRON RADIATION-INDUCED BYSTANDER EFFECT

Summary
Radiotherapy, a major treatment for more than half of cancer patients, is based on the dogma that radiation kills targeted cells. The radiation-induced bystander effect, by which the neighbours of irradiated cells can also damaged, is a new paradigm. What is the "danger signal" which induces DNA damage in un-irradiated normal tissues, and what minimal volume of tissue needs to be irradiated to induce bystander damage? The answers could have a major impact on optimising radiotherapy treatment.
Monitoring Changes In CT Scanning Usage To Minimise Cancer Risk?

Funding Amount

Summary
Computed tomography scanning (CT) is an x-ray technique that uses ionizing radiation to produce the images of the body. Ionizing radiation is harmful and carries a risk of cancer. Concerns have been expressed about the increasing use of CT with the importance of monitoring the trends in use recognised internationally. We will investigate changes in the use of CT, estimate the radiation dose and the number of cancers that can be expected due to CT.
Analysis Of Low Radiation Dose Outside Of The Treatment Field Received By Cancer Patients Undergoing Radiotherapy

Summary
Every medical intervention is associated with risk. The present proposal aims to quantify the dose from radiation that is delivered outside the actual target region in radiotherapy of breast cancer patients. This information can help the development of better irradiation techniques as well as inform patients and their carers about possible long term side effects. Finally, the research can be used to finetune radiobiological models by comparing clinical outcomes and accurately calculated doses.

Summary
Our study will inform the national health care policy debate with respect to the future role of CT scanning in the health system, and provide the information needed to launch the dialogue among expert clinicians and technicians necessary for practitioner consensus in the appropriate methods for use of CT scanning. This study will use routinely collected administrative health data and data collected from CT scan providers in WA to evaluate the use of CT scanning in the Australian health system.
A Multicentre Feasibility Study Of Partial Breast Irradiation Using 3D Conformal Radiotherapy For Early Breast Cancer

Summary
Breast conserving therapy (BCT) is an accepted treatment option for most women with early breast cancer. Whole breast irradiation (WBI) after breast conserving surgery substantially reduces the risk of breast recurrence. However, the prolonged 5-7 week course of WBI substantially decreases the quality of life (QoL) experienced by women and is a logistical problem particularly for the elderly and women who reside far from a radiotherapy (RT) facility.

Whole breast irradiation (WBI) after breast conserving surgery substantially reduces the risk of breast recurrence. However, the prolonged 5-7 week course of WBI substantially decreases the quality of life (QoL) experienced by women and is a logistical problem particularly for the elderly and women who reside far from a radiotherapy (RT) facility. In order to improve the access and convenience of BCT, accelerated partial breast irradiation (APBI) is being investigated. Research shows that 75% of the breast recurrences occur at the tumour bed after BCT implying that in selected women, RT may be limited to the tumour bed only. By limiting the breast volume irradiated, it is feasible to accelerate radiation dose delivery and reduce overall treatment time. In addition, a shorter schedule permits more efficient use of RT resources. To determine if APBI could replace WBI as standard of care for selected women with early breast cancer treated with BCT, it is necessary to demonstrate its technical feasibility and equivalence of outcomes compared to WBI. This study investigates the feasibility, toxicity, cosmetic outcome, local control and QoL of women with early breast cancer treated with APBI using a novel technique. It uses advanced 3-dimensional RT planning and multiple fields shaped to conform to the target volume (tumour bed) and spare the normal organs. It is more likely than the other modalities to be adopted as the preferred APBI technique in Australia because it uses equipments readily available in most RT centres and being non-invasive, is likely to be preferred by patients. However, its feasibility in multiple Australian centres with varying RT equipments is unclear. Given the current high level of international interest, it is timely to conduct this feasibility study in preparation for large scale research to determine if APBI may replace WBI in BCT.Read moreRead less
