Objectives: The CMFEV (cyclophosphamide, methotrexate, 5-fluorouracil, epirubicin, vincristine) regimen is an innovative schedule, designed by our Group, aimed at administering five partially or totally no cross-resistant cytotoxic agents in breast carcinoma. It was randomly compared to CMF (cyclophosphamide, methotrexate, 5-fluorouracil) as primary treatment in operable disease and demonstrated a short-term significant increase in clinical complete response rate and a long-term significant locoregional relapse-free survival in premenopausal patients. So, it seemed worth comparing this regimen with CMF as adjuvant chemotherapy in moderate risk operable breast carcinoma. Methods: Four hundred and eighty-nine patients with stage I or II moderate risk breast carcinoma were randomized to receive CMF or CMFEV regimen for 6 cycles after surgery. Main end points were overall survival (OS), invasive disease-free survival (IDFS) and recurrence-free interval (RFI), as estimated by Kaplan-Meier analyses and log-rank tests. Results: At a median observation time of 7.3 years (range 5.4 months-10.3 years), no significant differences in OS and IDFS were observed between the two arms. Deaths from breast carcinoma were more frequent with CMF (58.5%) than with CMFEV regimen (41.7%) as well as recurrences from breast carcinoma (58.8% with CMF and 41.2% with CMFEV). These differences were not statistically significant. Conclusion: CMFEV appears more effective than CMF in preventing recurrences from primary disease in patients with moderate risk stage I-II breast carcinoma. The lack of statistical significance of the observed differences was probably due to the limited number of patients enrolled which rendered the study underpowdered.
