A retrospective analysis from the MA5 Trial, randomly assigning patients to receive either CMF or CEF adjuvant chemotherapy, showed an increased 5-year DFS for the former (71% versus 51%, respectively) among patients with Basal-like breast cancer (BLBC); the test for interaction between Basal-like phenotype and treatment arm reached borderline significance ( P = 0.06) indicating that patients with TNBC may not derive a particular benefit from anthracyclines [ 48 ].
