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).
Rowan T. Chlebowski, MD, PhD, of the City of Hope National Medical Center, discusses 11-year followup results that showed a significantly lower breast cancer incidence among women with a greater than 5% weight loss (Abstract GS5-07).
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).
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).
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).
Joseph A. Sparano, MD, of Montefiore Medical Center/Albert Einstein College of Medicine, discusses findings that suggest circulating tumor cells 5 years after diagnosis are prognostic for late recurrence in operable stage II–III breast cancer (Abstract GS6-03).
