Physician Summary

Katherine D. Crew, M.D., M.S. is an Assistant Professor of Medicine and Epidemiology at the NewYork-Presbyterian/Columbia University Medical Center. Dr. Crew cares for patients with breast cancer and women at high-risk for breast cancer.

Dr. Crew received her undergraduate B.S. in Biochemistry from Brown University, where she graduated Magna Cum Laude. She received her M.D. from Columbia University College of Physicians and Surgeons and her M.S. from Columbia University School of Public Health. She completed her Internal Medicine residency and Medical Oncology fellowship at NewYork-Presbyterian/Columbia University Medical Center. Dr. Crew is currently involved in patient care, clinical research, and teaching on the Breast Oncology service.

Dr. Crew’s research involves the development of early phase clinical trials for evaluating chemopreventive agents for breast cancer. These studies implement intermediate markers for breast cancer risk, such as mammographic density, tissue- and serum-based biomarkers. In a presurgical study design, women with newly diagnosed breast cancer are given a short-term drug administration during the interval between breast biopsy and surgical resection to test the biologic activity of the drug in breast tumor tissue. In the phase I/II setting, clinical trials are underway to study high-dose vitamin D and a green tea extract, Polyphenon E, in high-risk women. Dr. Crew also participates in multicenter breast cancer chemoprevention trials through the Phase I/II Chemoprevention Trials Consortium and the Southwest Oncology Group (SWOG). The overall goal of this research is to build a comprehensive, interdisciplinary breast cancer prevention program, which will offer preventive strategies to breast cancer patients and healthy, high-risk women.
