Dejan Juric, MD, of Massachusetts General Hospital, discusses phase III study findings on liquid biopsy–based assessment of PIK3CA mutational status and the combination of the selective PI3K-alpha inhibitor alpelisib plus fulvestrant in the treatment of advanced breast cancer (Abstract GS3-08).
Hope S. Rugo, MD, of the University of California, San Francisco, discusses how treatment with a lower dose of palbociclib (100 mg vs 125 mg) in combination with fulvestrant or tamoxifen is associated with a lower rate of high-grade neutropenia (Abstract PD2-12).
Shom Goel, MD, PhD, of the Dana-Farber Cancer Institute, discusses preclinical data that suggest CDK4/6 inhibitors not only stop the growth of breast cancer cells, but also enhance antitumor immunity, a phenomenon that might help improve outcomes for people with advanced disease.
François-Clément Bidard, MD, PhD, of the Institut Curie and the University of Versailles, discusses phase III study findings on the clinical utility of circulating tumor cell count as a tool to choose between first-line hormone therapy and chemotherapy for estrogen receptor–positive, HER2-negative metastatic breast cancer (Abstract GS3-07).
Judy E. Garber, MD, of the Dana-Farber Cancer Institute, summarizes a special session she moderated, which included discussion of polygenic risk scores, genetic testing in diverse populations, and what to do when presented with moderate-penetrance mutations.
Kathy S. Albain, MD, of Loyola University Stritch School of Medicine, discusses study findings on race, ethnicity, and patient outcomes in hormone receptor–positive, HER2-negative, node-negative breast cancer (Abstract GS4-07).
