Andrew D. Seidman, MD, and Charles E. Geyer, MD, on HER2-Positive Breast Cancer: Results From the KATHERINE Trial
2018 San Antonio Breast Cancer Symposium
Andrew D. Seidman, MD, of Memorial Sloan Kettering Cancer Center, and Charles E. Geyer, MD, of Virginia Commonwealth University, discuss phase III study findings on ado-trastuzumab emtansine vs trastuzumab as adjuvant therapy in patients with early HER2-positive breast cancer with residual invasive disease after neoadjuvant chemotherapy and HER2-targeted treatment (Abstract GS1-10).
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).
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).
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).
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).
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.
