Nadia Harbeck, MD, of the University of Munich, discusses the first outcome data from the phase III ADAPT HR+/HER– trial, which combined both static and dynamic biomarkers to optimize the adjuvant therapy approach in patients with intermediate- or high-risk luminal early breast cancer (Abstract GS4-04).
Lee S. Schwartzberg, MD, of the West Cancer Center, discusses phase III results from the CONTESSA study, which showed that an all-oral regimen of tesetaxel plus a reduced dose of capecitabine significantly improved progression-free survival compared with capecitabine alone in patients with HER2-negative, hormone receptor–positive metastatic breast cancer previously treated with a taxane (Abstract GS4-01).
Editor's note: On March 22, 2021, Odonate Therapeutics announced it was discontinuing the development of tesetaxel and will close the company's operations. Read more here.
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).
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.
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).
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).
