Research Summary:

Breast cancer has been the focus of Dr. Hanna's research for the last 25 years. Specifically, she has concentrated on the investigation of biological markers as prognostic and predictive factors for response to therapy. The technology she used was predominantly immunohistochemistry and light microscopy. However, in certain areas, in particular, molecular biology, she used polymerase chain reaction. The biological markers included hormone receptors, the HER2/neu oncogene and many molecular markers that are involved in angiogenesis and may play a role in invasiveness. The subset of cohorts used was part of the Henrietta Banting Breast Centre database, the compiling of which involved collection of blocks and slides from 2,000 patients, and statistical compilation of demographics, treatment modalities and clinical outcomes for these patients. Many of the findings from the research were applied to this cohort and tumour bank.

The major focus of Dr. Hanna's research now is on ductal carcinoma in-situ, in particular on markers that are predictive for recurrence, especially invasive recurrence.

Dr. Hanna is also involved in the standardization of testing for molecular markers for breast cancer. She has been involved in setting guidelines locally, nationally and internationally, specifically for hormone receptors and Her2/neu testing.
