Key clinical point: Surgery followed by adjuvant chemotherapy (ACT) did not demonstrate inferior survival outcomes compared with neoadjuvant chemotherapy (NACT) followed by surgery in patients with clinical stage T1 node-negative (T1N0) triple negative breast cancer (TNBC), whereas NACT was more effective than ACT in clinical stage T1c BC.
Major finding: Patients with T1N0 TNBC who received NACT vs ACT had worse overall survival (OS) outcomes (hazard ratio 1.42; P < .001); however, OS was better in patients with clinical stage T1c TNBC who achieved pathological complete response with NACT vs those with unchanged stages who underwent surgery and received ACT (94.4% vs 91.9%; P = .025).
Study details: This retrospective analysis included 35,521 patients with T1N0 TNBC from the US National Cancer Database who received either adjuvant chemotherapy after upfront surgery (n = 32,066) or neoadjuvant chemotherapy before surgery (n = 3455).
Disclosures: This study did not declare any funding source or conflicts of interest.
