Summary
Breast screening has been successful in reducing deaths from breast cancer. Unfortunately it also detects increasing numbers of precancerous changes. Treatment of these changes is often aggressive, using surgery and radiotherapy. However we are unable to predict exactly which of the changes we need to treat. We aim to better understand the changes involved in this progression and try to block them using new drugs.
Translating Molecular Pathology Into Cancer Diagnostics

Summary
The aim of this research is focussed on translation of basic science through to the clinic by introducing novel cancer diagnostics and technologies. Other integral aims are to identify new changes in DNA and other cancer cell markers in patients, assess the clinical utility of these as biomarkers (surrogates of cancer behaviour) and to conduct novel clinical trials with newly identified molecular targets of cancer and new therapeutics and combinations to assess their efficacy.
Predictive And Prognostic Factors From The Tumour Microenvironment In Breast Cancer.

Summary
While most of the current treatments available are directed against cancerous tumour cells, there is increasing evidence that other factors within the tumour mass (or tumour microenvironment) may have an impact on prognosis. These factors include the lack of tissue oxygen and the immune response mounted by the body against the tumour cells. The impact of these factors on prognosis and their association with microRNAs (small RNA fragments which control protein production) will be investigated.

Summary
The objective is to develop magnetic resonance spectroscopy (MRS) for the rapid and accurate intra-operative detection of cancer cells in sentinel lymph nodes from breast cancer patients. Accurate intra-operative diagnosis of cancer in lymph nodes will enable informed decisions to be made regarding surgery and therapy and reduce the morbidity associated with complete clearance of axillary nodes. Using current histopathological techniques (frozen section) this is not possible.

Accurate intra-operative diagnosis of cancer in lymph nodes will enable informed decisions to be made regarding surgery and therapy and reduce the morbidity associated with complete clearance of axillary nodes. Using current histopathological techniques (frozen section) this is not possible. Proton MRS can detect chemicals in malignant cells in lymph nodes with a greater sensitivity than histology and can detect micrometastases in 20 minutes. The MR diagnostic information can be obtained from fine needle biopsies (FNB) making the technique eminently suitable for rapid intra-operative diagnosis. The FNB technique has been shown to be a rapid and accurate method for the assessment of breast lesions, distinguishing benign lesions and invasive cancer with a sensitiviy and specificity of 95% and 96%, respectively. Here we propose to evaluate the use of MRS for the rapid and accurate assessment of sentinel nodes from breast cancer patients. Two blinded studies will be conducted comparing the MRS chemical fingerprints with serial section histopathological data. To evaluate the clinical significance of the MRS diagnosis, all patients will be entered into a prospective study correlating the MRS data with recurrence of disease within 3 and 5 year periods.Read moreRead less
