Jack Cuzick, PhD, of Queen Mary University of London, discusses the substantially greater benefits of anastrozole as compared with tamoxifen in terms of preventing breast cancer, with no increase in fractures or other reported serious side effects (Abstract GS4-04).
Gerardo Antonio Umanzor Funez, MD, of Liga Contra El Cáncer, discusses phase III findings on intravenous (IV) paclitaxel and oral paclitaxel plus encequidar (a novel P-gp inhibitor), the first orally administered taxane regimen shown to be superior to the IV formulation in terms of response and survival with less neuropathy (Abstract GS6-01).
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).
Priyanka Sharma, MD, of the University of Kansas Medical Center, reviews new phase III data on adding oral fluoropyrimidine to adjuvant endocrine therapy, the current standard of care, in the setting of hormone receptor–positive, HER2-negative primary breast cancer (Abstract GS1-09).
Milan Radovich, PhD, of Indiana University School of Medicine, discusses trial findings that show patients with triple-negative breast cancer who are at high risk of relapse after receiving preoperative chemotherapy can be risk-stratified based on the presence of minimal residual disease as determined by circulating tumor DNA and circulating tumor cells (Abstract GS5-02).
Javier Cortes, MD, PhD, of the IOB Institute of Oncology, discusses study findings that suggested pembrolizumab offered a prolonged survival benefit compared to chemotherapy for a subset of patients with previously treated metastatic triple-negative breast cancer. In the trial, high tumor-infiltrating lymphocytes were significantly associated with better clinical outcomes with the checkpoint inhibitor.
