Sara M. Tolaney, MD, MPH, of Dana-Farber Cancer Institute, discusses phase II findings on patients receiving T-DM1 monotherapy as adjuvant treatment for stage I HER2-positive breast cancer, a regimen associated with few recurrences in the study population (Abstract GS1-05).
Rashmi K. Murthy, MD, of The University of Texas MD Anderson Cancer Center, discusses data on the efficacy and safety of tucatinib, trastuzumab, and capecitabine, a treatment regimen under investigation for patients with advanced HER2-positive metastatic breast cancer refractory to standard-of-care regimens (Abstract GS1-01).
Hope S. Rugo, MD, of the University of California San Francisco Comprehensive Cancer Center, discusses trial data on margetuximab plus chemotherapy, which improved progression-free survival in patients with previously treated HER2-positive metastatic breast cancer when compared with trastuzumab plus chemotherapy. Maturing data comparing overall survival also provides new insights (Abstract GS1-02).
Belinda Kingston, MB ChB, of the Institute of Cancer Research London, discusses next-generation sequencing results from the plasmaMATCH trial, including the incidence of gene alterations overall, as well as the associations with clinical and pathologic features that may help direct treatment decisions (Abstract GS3-07).
Terry P. Mamounas, MD, MPH, of Orlando Health UF Health Cancer Center, discusses 10-year results from NRG Oncology/NSABP B-42, which showed that, for postmenopausal women with hormone receptor–positive breast cancer who have completed previous adjuvant therapy with an aromatase inhibitor or with tamoxifen followed by an aromatase inhibitor, extended treatment with letrozole improved disease-free survival (Abstract GS4-01).
