Research Summary:

Dr. Jerzak’s goal as a medical oncologist with training in clinical epidemiology is to advance translational research in breast and gynecologic oncology. Specifically, she is engaged in clinical trials that aim to improve survival of women with these cancers. To further this goal, she is participating in the Canadian Cancer Trials Group as a member of the Breast Disease Site Group, and as a member of the Investigational New Drug Committee.

Her research projects include the following:

  1. Developing biomarkers of response to neoadjuvant chemotherapy among women with breast cancer.
  1. Developing biomarkers of response to systemic therapy among women with gynecologic cancers. These involve novel, genomic-based and 3-D tumour organoid assays.
  1. Routine MRI screening versus symptom-directed screening for brain metastases among patients with triple negative or HER2+ metastatic breast cancer: a randomized Phase 2 pilot study.
  1. Developing a novel class of anticancer agents: repurposing dronedarone, a class III anti-arrhythmic agent, in breast and other cancers.
