ERBB2 and triple-negative breast carcinoma: This study confirmed that HER-2 overexpression, Luminal B HER2+, and triple-negative breast cancer (TNBC) were favorable subtypes to achieve a pCR, while the pCR rates of Luminal B/HER2− and Luminal A type were low, which was consistent with the majority of previously published studies (6, 17–19).
