Key clinical point: Platinum agents do not improve outcomes in patients with basal subtype triple-negative breast cancer (TNBC) and residual invasive disease post-neoadjuvant chemotherapy (NAC) and are associated with higher toxicity rate vs. capecitabine.
Major finding: The invasive disease-free survival was not significantly different between platinum and capecitabine groups (hazard ratio, 1.06; 95% confidence interval, 0.62-1.81) after a median follow-up of 20 months. Grade 3 and 4 toxicities were more frequent in the platinum vs. capecitabine group (26% vs. 15%).
Study details: A phase 3, randomized controlled EA1131 trial involving 415 patients with stage II-III TNBC post-NAC, randomly assigned to receive platinum-based chemotherapy or capecitabine.
