A young woman is referred urgently to your breast surgical oncology clinic for a second opinion. She has been told that she needs to have an urgent mastectomy for a palpable triple negative breast cancer with suspicious axillary lymphadenopathy. Are there other options she should consider? Join Drs. Michael Alvarado, Rita Mukhtar, and Alexa Glencer as they discuss the multidisciplinary management of a patient with triple negative breast cancer.

In this episode, we review the diagnosis and classification of triple negative breast cancer, its biologic implications, surgical management including the role of sentinel lymph node biopsy vs axillary dissection, and the role of targeted chemotherapy including the recent FDA approval of immunotherapy for triple negative breast cancer in the neoadjuvant setting and indication for adjuvant chemotherapy for patients with residual disease following neoadjuvant therapy.
