Dr. Domchek on Promising Biomarkers in Breast Cancer

Susan Domchek, MD, director of the Basser Center for BRCA at Penn Medicine, discusses promising biomarkers in breast cancer.

Biomarkers such as BRCA1/2 are currently used to determine treatment for patients with breast cancer, explains Domcheck.

Domcheck adds that if a patient is microsatellite instability-high (MSI-H), then that patient can receive pembrolizumab (Keytruda) regardless of tumor site.
