To assess the impact in pathological complete response (pCR) and outcome of two dose-dense neoadjuvant chemotherapy (DDNC) regimens among different histological subtypes determined by hormonal receptor (HR) and HER2 status in breast cancer patients. ⋯ HR-/HER2- and HR-/HER2+ subtypes had a high pCR rate to DDNC. HR-/HER2- tumors had a worse outcome compared to other tumor subtypes but no significant difference was observed among HR-/HER2- tumors that achieved a pCR.
