Joyce V. Lee, PhD, on Triple-Negative Breast Cancer: MYC as a Predictor of Treatment Response
2020 San Antonio Breast Cancer Symposium
Joyce V. Lee, PhD, of the University of California, San Francisco, discusses data that suggest the MYC oncogene may indicate whether a patient with triple-negative breast cancer will respond to immunotherapy. Dr. Lee’s study is the first to describe MYC downregulation of MHC-I and to demonstrate translatable approaches that may overcome immune evasion (Abstract GS1-08).

Elizabeth A. Mittendorf, MD, PhD, of Brigham and Women’s Hospital, summarizes her plenary talk, which featured the uncertainties in treatment knowledge: excision of postchemotherapy calcifications; the best sentinel lymph node biopsy technique for patients with node-positive disease who convert to node-negative disease with neoadjuvant chemotherapy; whether immunohistochemistry should be routinely used for sentinel lymph node evaluation; and the role of radiation therapy in this patient population.

Patricia A. Ganz, MD, of the University of California, Los Angeles, discusses study findings that showed mindfulness meditation and survivorship education may effectively reduce depression and related symptoms such as fatigue and sleep disturbance, which pose serious threats to younger women’s health and well-being after being treated for cancer (Abstract GS2-10).

Sibylle Loibl, MD, of the German Breast Group, discusses the first phase III results from the PENELOPE-B study of palbociclib combined with endocrine therapy in patients with hormone receptor–positive, HER2-negative primary breast cancer who are at high risk for relapse after neoadjuvant chemotherapy (Abstract GS1-02).

Sara A. Hurvitz, MD, of the David Geffen School of Medicine at UCLA, discusses phase III data from the ASCENT study of the antibody-drug conjugate sacituzumab govitecan vs chemotherapy in patients with previously treated metastatic triple-negative breast cancer (Abstract GS3-06).

Roisin M. Connolly, MD, of University College Cork, discusses phase III results from the E2112 trial, which showed exemestane plus entinostat did not improve survival in aromatase inhibitor–resistant advanced HR-positive, HER2-negative breast cancer (Abstract GS4-02).
