Elizabeth A. Mittendorf, MD, PhD, on Her Plenary Lecture: Local Regional Management Following Neoadjuvant Therapy
2020 San Antonio Breast Cancer Symposium
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.

Chirag Shah, MD, of the Cleveland Clinic, discusses the impact of DCISionRT testing on radiation therapy recommendations for patients with ductal carcinoma in situ following lumpectomy. His study found that despite using traditional favorable-risk criteria, radiation recommendations were changed in more than 40% of patients (Abstract PS6-17).

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).

Ann H. Partridge, MD, MPH, of Dana-Farber Cancer Institute, discusses results from the ALTERNATE trial on response to neoadjuvant chemotherapy in postmenopausal women with clinical stage II or III estrogen receptor–positive and HER2-negative breast cancer that is resistant to endocrine therapy. The findings highlight the need for more effective treatments in this high-risk population (Abstract GS4-05).

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).

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).
