Combination chemotherapy in advanced postmenopausal mammary carcinoma. A comparison between VAC and VACM therapy.

Abstract

A randomized trial comparing Vincristine, Adriamycin, Cyclophosphamide (VAC) with or without Methotrexate with citrovorum factor rescue (VACM) was performed in 64 patients with metastatic postmenopausal mammary carcinoma. Previous treatment of metastases, dominant site of metastases and performance condition were similar in the patients. No significant difference was found in the response rates (complete remission + partial remission; VAC 21/31, VACM 25/33), in the duration of the remissions or in the survivals. The duration of remission in CR was significantly longer than in PR. No serious side effects were observed. The VAC regimen is preferable, particularly with respect to the costs and the simple procedure of administration.
