Chemotherapy of advanced breast cancer: A randomized trial of vincristine, adriamycin, and cyclophosphamide (VAC) versus cyclophosphamide, methotrexate, 5-fluorouracil, and prednisone (CMFP)

Abstract

Fifty-one patients with metastatic breast cancer were randomly allocated to receive either a four drug combination consisting of cyclophosphamide, methotrexate, 5-fluorouracil, and prednisone (CMFP), or a combination of vincristine, Adriamycin, and cyclophosphamide (VAC) with cross-over on relapse. Objective responses were seen in 17 of 26 patients (65%) in the CMFP group and in 14 of 25 patients (56%) in the VAC group, but this difference was not statistically significant. The median duration of response for each group was one year. The estimated median survival was greater for the CMFP group, but this was not significant. Toxicity was more severe with the VAC regimen. It is concluded that there is no therapeutic advantage of the VAC over the CMFP regimen.
