Key clinical point: Neoadjuvant chemotherapy (NAC) that did vs did not contain cisplatin improved survival in patients with operable triple-negative breast cancer (TNBC), especially those with residual cancer burden (RCB) class II/III, a group that is typically associated with worse prognosis.
Major finding: Patients who did vs did not receive cisplatin-based regimens in the overall population reported significantly improved distant disease-free survival (unadjusted hazard ratio [HR] 0.127; P < .001), especially those in the RCB class II/III group (HR 0.192; P = .013).
Study details: Findings are from a retrospective cohort study including 138 previously untreated patients with stage I-III TNBC who received NAC with (n = 52) or without (n = 86) cisplatin.
