Summary
The main complication in breast cancers leading to death is metastatic relapse. This research aims to understand the role for a protease that promotes spread of breast cancer to the lymph nodes and lungs. The outcomes will identify a novel process that leads to lymph node metastasis and offer a new target for therapies that prevent relapse and tests to identify breast cancer patients at risk of relapse.

This application covers 4 adjuvant early breast cancer trials currently part of the Australian New Zealand Breast Cancer Trials Group's national research programme. These trials are international collaborations involving the International Breast Cancer Study Group (IBCSG). Two of the studies concern pre, peri and post-menopausal women with early breast cancer and no involved lymph glands (IBCSG 8 and 9), and two concern pre, peri and post-menopausal women with early breast cancer and involved ly ....This application covers 4 adjuvant early breast cancer trials currently part of the Australian New Zealand Breast Cancer Trials Group's national research programme. These trials are international collaborations involving the International Breast Cancer Study Group (IBCSG). Two of the studies concern pre, peri and post-menopausal women with early breast cancer and no involved lymph glands (IBCSG 8 and 9), and two concern pre, peri and post-menopausal women with early breast cancer and involved lymph glands (IBCSG 13 and 14). In the absence of a definitive cure, the largest gains will come from optimal use of current therapies and new therapies to improve survival, and where possible, to reduce morbidity without the loss of efficacy. These four trials can realistically expect to produce important gains with potential benefit to the many women who are diagnosed with early breast cancer each year. The active accrual period for these studies is complete but all patients are currently on life long follow-up. Patients accrued to trial 8 have a clinical assessment 3 monthly to 2 years, 6 monthly to 5 years, and then annually. For trials 9, 13 and 14 women have a clinical assessment 3 monthly during year 1, 6 monthly for year 2 and then annually.Read moreRead less
Follow-up Of Women On A Randomised Clinical Trial Of Adjuvant Docetaxel And Doxorubicin For Node Positive Breast Cancer.

Summary
This project is testing the use of a drug docetaxel in the post-operative (adjuvant) treatment of women with breast cancer and involved lymph nodes (N+). Until recently the drug doxorubicin was the most active chemotherapy drug for breast cancer, but more recently a new group of chemotherapy drugs called taxanes were identified. One taxane called docetaxel may be even more effective than doxoubicin. Using available treatments that include doxorubicin based chemotherapy, approximately half the wo ....This project is testing the use of a drug docetaxel in the post-operative (adjuvant) treatment of women with breast cancer and involved lymph nodes (N+). Until recently the drug doxorubicin was the most active chemotherapy drug for breast cancer, but more recently a new group of chemotherapy drugs called taxanes were identified. One taxane called docetaxel may be even more effective than doxoubicin. Using available treatments that include doxorubicin based chemotherapy, approximately half the women with N+ breast cancer experience recurrence of their cancer. It is therefore important to test whether the inclusion of docetaxel in adjuvant therapy can reduce relapses. If docetaxel is to be included, it is also important to test whether it is best to combine it with doxorubicin at the same time (which for safety reasons requires the doses of each drug to be reduced), versus giving them sequentially at full dose. Currently, docetaxel is not approved nor funded for use in early breast cancer in Australia. There are several international trials testing the inclusion of taxanes in the adjuvant therapy of breast cancer. However this trial stands out, because all the women in the trial receive chemotherapy of at least 6 months. In some other trials, testing the possible benefit of adding a taxane, women in the control treatment group (who were randomised not to receive the taxane) received only 3 months of treatment, which makes it difficult to distinguish between longer treatment or addition of the taxane drug. This trial has completed international recruitment of 2890 women who will be carefully followed for 10 years. Australian and New Zealand centers recruited 20% of the women in the trial. After the women have been followed-up for 5 years the results of this trial will be analysed, presented and published and should provide reliable evidence about the potential benefit of adding docetaxel into adjuvant chemotherapy.Read moreRead less

Summary
This project is investigating the optimal use of docetaxel and doxorubicin in the treatment of women with breast cancer and involved lymph nodes (N+). Every year 3000 women in Australia, and over 400,000 worldwide are newly diagnosed with N+ breast cancer. Using available treatments more than 60% of these (5 per day in Australia, 4,500 each week worldwide) will die from breast cancer.

Every year 3000 women in Australia, and over 400,000 worldwide are newly diagnosed with N+ breast cancer. Using available treatments more than 60% of these (5 per day in Australia, 4,500 each week worldwide) will die from breast cancer. The efficacy of adjuvant chemotherapy in early breast cancer is well established by the international overview conducted by the Early Breast Cancer Trialist's Collaborative Group (EBCTCG). They have demonstrated the efficacy of adjuvant chemotherapy on reducing mortality and recurrence rates, but current regimens are far from optimal. Docetaxel (Taxotere), a new agent, has effectiveness and manageable side effects in the treatment of advanced breast cancer patients, and can plausibly improve outcomes for patients with early N+ breast cancer by optimal integration into current adjuvant chemotherapy regimens. This clinical trial is designed to compare whether it is advantageous to use docetaxel and-or doxorubicin in combination or sequentially with other currently available chemotherapy drugs.Read moreRead less
Compartmental Analysis Of T-cell Responses In Thoracic Malignancies

Funding Amount
$851,403.00
Summary
To improve immune therapy for cancer we have to be able to determine how cancer patients ‘see’ mutated cancer proteins. Blood is the easiest & most useful source of immune ‘killer’ cells for that task, but the lymph node that drains the tumour and the fluid that bathes a tumour probably contain a much higher number of these killer cells than blood. If so, studying them would help us better track responses to therapy and enable us to choose the best mutated proteins for a vaccine.

Summary
POSNOC (POsitive Sentinel NOde – adjuvant therapy alone versus adjuvant therapy plus Clearance or axillary radiotherapy) will address the key unresolved challenge in breast cancer surgery. A controversial US trial, ACOSOG Z0011, indicates that many breast cancer patients with limited disease in the sentinel node can safely avoid further nodal surgery. This would be a major advance, but there is widespread doubt that the results are broadly applicable. POSNOC will clarify this key issue.
Uncovering The Role Of Collecting Lymphatic Vessels In Cancer.

Summary
Lymphatic vessels are a critical part of the circulatory system, allowing the return of fluid and cells that escape the blood vessels, and playing an intimate role in the body's immune function. In cancer, the lymphatic vessels serve as conduits for the transport of tumour cells to lymph nodes and may contribute to distant metastasis. Our study is designed to understand the role played by major collecting lymphatic vessels in cancer and to identify molecules that control their activity.
Creating Treatment Options For Endometrial Cancer Through High-level Clinical Trials

Summary
Endometrial cancer (EC) arises from the inner lining of the womb. Treatment typically involves surgery (hysterectomy) to remove the womb and explore if cancer has affected the lymph glands in the pelvis. The benefit of surgery on the lymph glands is doubtful. My research program will generate evidence to inform clinical practice on the treatment of EC and explore non-surgical treatment alternatives to a hysterectomy for better patient outcomes, particularly in women who wish to start a family.
The Relationship Between Cancer Surgery, Lymph Nodes, T Cells And Immunotherapy.

Summary
Cancer treatment involves surgery for millions of patients annually, however, many patients do relapse. Surgery often involves removal of cancer-associated lymph nodes at the site. To improve surgical outcomes new immunotherapy strategies aim to activate the patients’ immune cells to eradicate tumours. However the main repository for these immune cells is in the very lymph tissue removed at surgery. This project will investigate the role of remaining lymph nodes in patient recovery/response.
