Ciara C. O’Sullivan, MD, MBBCh, on HER2-Positive Breast Cancer: Expert Commentary on Treatments Under Study
2024 ASCO Annual Meeting
Ciara C. O’Sullivan, MD, MBBCh, of Mayo Clinic, discusses three studies of treatment for patients with HER2-positive metastatic breast cancer and their clinical implications: the EMERALD trial of eribulin and taxane; the Patricia Cohort C trial of palbociclib plus trastuzumab and endocrine therapy; and DB07 on trastuzumab deruxtecan with or without palbociclib.

Reshma Jagsi, MD, DPhil, of Emory University Winship Cancer Institute, and Christian F. Singer, MD, MPH, of the Medical University of Vienna, discuss the MUC-1 vaccine tecemotide. When added to standard neoadjuvant systemic therapy for patients with early-stage breast cancer, this vaccine improved distant relapse–free and overall survival rates. Despite the exploratory nature of this observation, says Dr. Singer, this is the first long-term survival benefit of an anticancer vaccine in breast disease reported to date (Abstract 587).

Belinda Lee, MBBS, of Peter MacCallum Cancer Centre, Northern Health, Walter & Eliza Hall Institute, Melbourne, discusses findings from the AGITG DYNAMIC-Pancreas trial on the potential role of serial circulating tumor DNA testing after upfront surgery to guide adjuvant chemotherapy for early-stage disease (Abstract 107).

Lisa A. Carey, MD, of the University of North Carolina, Chapel Hill and UNC Lineberger Comprehensive Cancer Center, and Dejan Juric, MD, of the Massachusetts General Hospital Cancer Center, discuss phase III findings on first-line use of inavolisib or placebo plus palbociclib and fulvestrant in patients with PIK3CA-mutated, hormone receptor–positive, HER2-negative locally advanced or metastatic breast cancer who relapsed within 12 months of completing adjuvant endocrine therapy (Abstract 1003).

Yeon Hee Park, MD, PhD, of South Korea’s Samsung Medical Center and Sungkyunkwan University, discusses phase II findings on palbociclib plus exemestane with a GnRH agonist vs capecitabine in premenopausal patients with hormone receptor–positive, HER2-negative metastatic breast cancer (LBA1002).

Anthony M. Joshua, MBBS, PhD, of Princess Margaret Cancer Centre, discusses results from the MAST study, which explored the question of whether metformin could reduce disease progression in men with low-risk prostate cancer who are undergoing active surveillance (LBA5002).
