Lynn J. Howie, MD, of the U. S. Food & Drug Administration, discusses a pooled analysis of outcomes of older women with hormone receptor–positive metastatic breast cancer treated with a CDK4/6 inhibitor as initial endocrine-based therapy (Abstract GS5-06).
Sibylle Loibl, MD, PhD, of the German Breast Group, discusses a study evaluating palbociclib plus endocrine treatment vs a chemotherapy-based treatment strategy in patients with hormone receptor–positive, HER2-negative metastatic breast cancer (Abstract OT3-05-04).
Sherene Loi, MD, PhD, and Roberto Salgado, MD, PhD, both of the Peter MacCallum Cancer Centre, discuss study findings on pembrolizumab and trastuzumab in patients with trastuzumab-resistant disease (Abstract GS2-06).
Richard G. Gray, MSc, of the University of Oxford, discusses an Early Breast Cancer Trialists’ Collaborative Group meta-analysis of 21,000 women in 16 randomized trials, which showed that increasing the dose density of adjuvant chemotherapy by shortening intervals between courses or sequentially administering treatment significantly reduces disease recurrence and breast cancer mortality (Abstract GS1-01).
Louis Fehrenbacher, MD, of Kaiser Permanente, discusses study findings comparing adjuvant chemotherapy with doxorubicin and cyclophosphamide followed by weekly paclitaxel—or docetaxel and cyclophosphamide—with or without a year of trastuzumab in women with node-positive or high-risk node-negative disease (Abstract GS1-02).
Nicholas C. Turner, MD, PhD, of The Royal Marsden Hospital NHS Trust, discusses the challenges of treating metastatic breast cancer and how liquid biopsies can serve as a guide to genetic phenotypes.
