A randomized trial of mitomycin-C (M) versus mitomycin-C plus high-dose medroxyprogesterone acetate (MMPA) in the treatment of patients with advanced breast cancer.
Seventy-six women with previously treated breast cancer were randomized to receive mitomycin (M) or M plus high-dose oral medroxyprogesterone acetate (MMPA). Patients were balanced with respect to age, performance status, hormone receptor status, previous treatment, and number of metastatic sites. There were more patients with visceral metastases in the M arm of the study. Side effects were tolerable and not significantly different for the two regimens. No life-threatening toxicity occurred. Objective response was documented in 4 of 37 patients on M and 11 of 39 on MMPA. On M the median time to treatment failure (TTF) was 3 months, and median survival was 7.8 months. On MMPA the median TTF was 4.4 months, and median survival was 9.7 months. There was a tendency for higher response and longer TTF and survival on MMPA, but statistical significance was not reached (p = 0.09).
