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.
Shanu Modi, MD, of Memorial Sloan Kettering Cancer Center, discusses study findings from a large phase I study on trastuzumab deruxtecan in patients with low HER2-expressing breast cancer (Abstract P6-17-02).
Laura S. Dominici, MD, of the Dana-Farber Cancer Institute, discusses the lower quality-of-life scores seen after unilateral or bilateral mastectomy compared with breast-conserving surgery in women younger than age 40 who are treated for breast cancer (Abstract GS6-05).
Eva M. Ciruelos, MD, PhD, of the University Hospital 12 de Octubre and the SOLTI Group, discusses study findings on palbociclib and trastuzumab in postmenopausal patients with HER2-positive metastatic breast cancer (Abstract PD3-03).
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).
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).
