Adjuvant treatment of node-positive breast cancer with cyclophosphamide, doxorubicin, fluorouracil, and vincristine versus cyclophosphamide, methotrexate, and fluorouracil: final report after a 16-year median follow-up duration.

PURPOSE: To determine the long-term impact on disease-free survival (DFS) and overall survival (OS) of adjuvant anthracycline-based chemotherapy, when prospectively compared by random allocation with standard cyclophosphamide, methotrexate, and fluorouracil (CMF) in node-positive (N+) breast cancer patients. PATIENTS AND METHODS: Two hundred forty-nine patients with N+ breast cancer, recruited from eight French cancer centers, were randomized to receive 12 monthly cycles of adjuvant chemotherapy, either CMF (n = 112) or doxorubicin, vincristine, cyclophosphamide, and fluorouracil (AVCF) (n = 136). All had a negative metastatic work-up before inclusion, which was stratified by accrual center, tumor stage (International Union Against Cancer [UICC]), and menopausal status. RESULTS: No severe adverse effect related to grade 4 (World Health Organization [WHO]) toxicity was observed. There was no difference in second primary tumor incidence between the two arms. The treatment given was 88% of planned for AVCF and 75% for CMF in both premenopausal and menopausal patients. With a median follow-up time of 16 years (range, 13 to 17), the OS and DFS rates are significantly longer in the AVCF arm (56% v 41% [P = .01] for OS, and 53% v 36% [P = .006] for DFS). These differences are significant, irrespective of tumor stage (T1 to T2 v T3 to T4), and remain positive in patients with or without postoperative locoregional radiotherapy (55% of cohort). When analyzed according to menopausal status, the differences remain significant only for premenopausal patients. CONCLUSION: This set of mature controlled data confirms the added value of anthracycline-based combination adjuvant therapy for N+ breast cancer patients when compared with CMF, with both regimens given for 1 year.[1]
