Funding Amount

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.
Compartmental Analysis Of T-cell Responses In Thoracic Malignancies

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.
POSNOC (Positive Sentinel Node – A Randomised Trial Of Adjuvant Therapy Alone Versus Adjuvant Therapy Plus Clearance Or Axillary Radiotherapy)

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.

Funding Amount
$960,585.00
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.
The Role Of Subcapsular Sinus Macrophages In Lymph Node Metastases

Funding Amount

Summary
This project tackles the problem of lymph node metastases using complementary studies in mouse models and human patients with melanoma. It takes the novel approach of examining the local geographical factors in the lymph node and focusses on a rare cell called the subcapsular sinus macrophage that may be a critical determinant of the clinical outcome. This will result in innovative strategies for primary prevention of not only melanoma but other cancer cell metastases.
The Microenvironmental Drivers Of T Cell Regulation In Metastatic Breast Cancer

Funding Amount
$1,302,611.00
Summary
COX2 inhibitors are drugs commonly used by cancer patients to relieve pain and inflammation. Using human breast cancer samples and mouse models of breast cancer, we show that pathways targeted by these drugs provide an immunological brake that prevents T cells being activated as strongly as they could be, and which has not been studied. This project is expected to yield important anti-cancer targets that could be used to develop a new class of cancer drugs.
