Kevin Kalinsky, MD, on HR-Positive HER2-Negative Breast Cancer: Endocrine Therapy and Chemotherapy
2021 San Antonio Breast Cancer Symposium
Kevin Kalinsky, MD, of the Winship Cancer Institute at Emory University, discusses updated phase III results from the SWOG S1007 (RxPONDER) study of women with one to three positive lymph nodes, and hormone receptor–positive, HER2-negative breast cancer. The data showed that postmenopausal women with recurrence scores (RS) from 0 to 25 continue not to benefit from adjuvant chemotherapy, whereas premenopausal women with a RS from 0 to 25 did benefit from the addition of chemotherapy to endocrine therapy (Abstract GS2-07).

Komal Jhaveri, MD, of Memorial Sloan Kettering Cancer Center, discusses the latest updates from the SUMMIT trial, which explored the combinations of neratinib/fulvestrant/trastuzumab and neratinib plus trastuzumab, as well as fulvestrant alone. The combination regimens appeared to benefit patients with hormone–receptor positive, HER2-mutated metastatic breast cancer who have had prior exposure to CDK4/6 inhibitors, and those with HER2-mutated triple-negative disease (Abstract GS4-10).

François-Clément Bidard, MD, PhD, of the Institut Curie, discusses phase III findings of the PADA-1 study, which showed that optimizing endocrine therapy after detecting the ESR1 mutation in patients with hormone receptor–positive, HER2-negative metastatic breast cancer may double their median progression-free survival (Abstract GS3-05).

Elizabeth A. Mittendorf, MD, PhD, of Dana-Farber Brigham and Women’s Cancer Center, discusses the progress made in recent years treating patients with triple-negative breast cancer (TNBC), including approval of the immunotherapy agents pembrolizumab and sacituzumab govitecan-hziy, a new standard of care in the preoperative setting for early-stage disease, as well as a better understanding of the biology of TNBC and its heterogeneity.

Banu Arun, MD, of The University of Texas MD Anderson Cancer Center, discusses a session she moderated that included discussion of how exercise and diet may reduce the risk of breast cancer, and emerging non-endocrine treatments that may help prevent the disease.

Ann H. Partridge, MD, MPH, of Dana-Farber Cancer Institute, discusses what she considers to be the most notable presentations at the 2021 San Antonio Breast Cancer Symposium. They include the focus on early-stage disease, especially in the TEXT/SOFT, RxPonder, and KEYNOTE-522 trials, as well as abstracts from the Early Breast Cancer Trialists’ Collaborative Group; and new data and novel therapeutics in the advanced setting.
