Fluorouracil, Epirubicin, and Cyclophosphamide With Either Docetaxel or Vinorelbine, With or Without Trastuzumab, As Adjuvant Treatments of Breast Cancer: Final Results of the FinHer Trial

Purpose Docetaxel has not been compared with vinorelbine as adjuvant treatment of early breast cancer. Efficacy and long-term safety of a short course of adjuvant trastuzumab administered concomitantly with chemotherapy for human epidermal growth factor receptor 2 (HER2) –positive cancer are unknown. Patients and Methods One thousand ten women with axillary node–positive or high-risk node-negative breast cancer were randomly assigned to receive three cycles of docetaxel or vinorelbine, followed in both groups by three cycles of fluorouracil, epirubicin, and cyclophosphamide (FEC). Women with HER2-positive cancer (n = 232) were further assigned to either receive or not receive trastuzumab for 9 weeks with docetaxel or vinorelbine. The median follow-up time was 62 months after random assignment. Results Women assigned to docetaxel had better distant disease–free survival (DDFS) than those assigned to vinorelbine (hazard ratio [HR] = 0.66; 95% CI, 0.49 to 0.91; P = .010). In the subgroup of HER2-positive dis...
