摘要: Background Amplification of the human epidermal growth factor receptor type 2 (HER2, also called HER2/neu) gene and overexpression its product in breast-cancer cells may be associated with responsiveness to anthracycline-containing chemotherapy regimens. Methods In randomized, controlled Mammary.5 trial, we studied 639 formalin-fixed paraffin-embedded specimens obtained from 710 premenopausal women node-positive breast cancer who had received either cyclophosphamide, epirubicin, fluorouracil (CEF) or methotrexate, (CMF) as adjuvant chemotherapy. HER2 amplification was evaluated use fluorescence situ hybridization, immunohistochemical analysis, polymerase-chain-reaction analysis. Results a poor prognosis regardless treatment. patients whose tumors showed HER2, CEF superior CMF when assessed on basis relapse-free survival (hazard r...
