Pathological complete response and prognosis in patients receiving neoadjuvant paclitaxel and trastuzumab with and without anthracyclines for stage II and III, HER2-positive operable breast cancer: a single-institute experience.
Trastuzumab and various chemotherapy combinations have shown superior results in patients with primary and metastatic breast cancer. However, cardiotoxicity becomes a major adverse event when trastuzumab is used with anthracycline-containing regimens. The purpose of this study was to determine the clinical and pathological efficacy of neoadjuvant chemotherapy (NAC), using trastuzumab and chemotherapy, with or without anthracyclines, for patients with primary breast cancer and human epidermal growth factor receptor 2 (HER2-)-positive tumors. ⋯ Trastuzumab-containing NAC is effective irrespective of anthracycline use for treating patients with primary breast cancer and HER2-positive tumors.
