Research Summary:

Dr. Trudeau's research interests cover the spectrum of breast cancer from prevention to treatment to palliative care. To date, her research has centred on the following:

  • clinical trials in prevention, and adjuvant and metastatic disease, including investigational new drugs
  • guidelines for the treatment of breast cancer and systemic therapy
  • real-world evidence in breast cancer treatment.

Her research findings have been published in many journals, including The New England Journal of Medicine, Journal of Clinical Oncology and Breast Cancer Research and Treatment.

In addition, Dr. Trudeau participates in clinical trials through the National Cancer Institute of Canada-Clinical Trials Group (NCIC-CTG), the National Surgical Adjuvant Breast and Bowel Project and in studies supported by grants from industry. She has also chaired several studies in breast cancer through NCIC-CTG.

The use of new cancer drugs, as well as drug funding, remain strong areas of research interest for Dr. Trudeau.

As co-chair of the breast disease site group for the program in evidence-based care at Cancer Care Ontario, she has authored many guidelines on the treatment of breast cancer; these have influenced drug funding decisions provincially and nationally. She has been vice-chair of the Pan Canadian Oncology Drug Review from 2011–2016 and chair since October 2016.
