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).
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).
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).
Rowan T. Chlebowski, MD, PhD, of the Lundquist Institute at Harbor-UCLA Medical Center, discusses the long-term influence of using estrogen plus progestin or estrogen alone on breast cancer incidence and mortality (Abstract GS5-00).
Hope S. Rugo, MD, of the University of California San Francisco Comprehensive Cancer Center, discusses a retrospective analysis on the effectiveness of the VENTANA PD-L1 SP142 assay, the Dako 22C3 assay, and the VENTANA SP263 assay as predictors of response to atezolizumab plus nab-paclitaxel in patients with metastatic triple-negative breast cancer (Abstract PD1-07).
Nicholas C. Turner, MD, PhD, of The Royal Marsden NHS Foundation Trust, discusses findings from the plasmaMATCH trial, which showed that circulating tumor DNA testing offers accurate tumor genotyping to identify patients with rare HER2 and AKT1 mutations and may enable matching them with targeted treatments (Abstract GS3-06).
