Key clinical point: Taxane + anthracycline-based chemotherapy (ATAX) vs taxane-based chemotherapy (TAX) did not increase the risk for major cardiovascular adverse events in older patients with early-stage triple-negative breast cancer (TNBC) or affect survival outcomes in those who had a cardiac event.
Major finding: The risks for acute myocardial infarction, potentially fatal arrhythmia, and cerebral vascular accident did not increase (all P > .1) and the risk for subsequent heart failure was lower in patients receiving ATAX vs TAX (odds ratio 0.63; P < .01). In patients who experienced a cardiac event, ATAX vs TAX did not worsen the survival outcomes.
Study details: This study analyzed the data from the Surveillance, Epidemiology, and End Results (SEER)-Medicare database and included 2215 older women (age ≥ 66 years) diagnosed with early-stage TNBC who received ATAX (39.78%) or TAX (60.26%) in an adjuvant setting.
Disclosures: This study was funded by the Women’s Cancer Developmental Therapeutics Program, University of Colorado Cancer Center. The authors declared no conflicts of interest.
