Abstract
Adriamycin is of noteworthy efficacy in the treatment of metastatic breast cancer. Its role in combination regimens is under investigation. One hundred seventy-five women with advanced breast cancer were entered into a prospectively randomized trial comparing two five-drug regimens. Regimen CMFVP consisted of cyclophosphamide (C), methotrexate (M), 5-fluorouracil (F), vincristine (V), and prednisone (P). Regimen CAFVP was identical but substituted Adriamycin (A) for methotrexate. Twenty-seven patients were disqualified; 148 were evaluable. With CMFVP the complete response rate (CR) was 11%, and the partial response rate (PR) was 46%; with CAFVP, CR was 13% and PR was 45%. Duration of response tended to be slightly longer for patients on the Adriamycin arm. The median survival for CR and PR patients with CMFVP was 20.2 months, which was shorter (p =.07) than the 33 month median survival with CAFVP. Although statistical significance was not reached at the 5% level, the increased survival of responders on the Adriamycin regimen supports the data of other studies which suggest that first line combination chemotherapy in advanced breast cancer should include Adriamycin.
