The research interests of Julie A. Margenthaler, MD, include the investigation of minimally invasive techniques using molecular analysis to stage the axilla in breast cancer patients. She is also very involved in the study of young women (<40 years) with breast cancer in order to identify the unique tumor characteristics in these patients and the novel hereditary markers present in their genome. Other interests include the investigation of the role of surgery in patients with metastatic breast cancer and the role of sentinel lymph node biopsy in multicentric breast cancers. Dr. Margenthaler is an investigator for the Program for the Elimination of Cancer Disparities and is currently investigating the barriers to early, effective breast cancer diagnosis and treatment in the underserved populations of St. Louis City.

The research interests of Amy E. Cyr, MD, are in the area of breast cancer staging, specifically evaluating non-surgical alternatives to axillary staging. Other interests include evaluating breast cancer patient decision-making, high-risk breast lesions, and effective use of health-care dollars.
