Salvage chemotherapy for relapsed and refractory metastatic breast cancer is a challenging issue for oncologists. At our institution, the combination of mitomycin-C, vinblastine and cisplatin (MVP) is used for treatment. The records of 19 consecutive patients with refractory metastatic breast cancer treated with MVP between April 1992 and October 1995 were reviewed. The regimen consisted of mitomycin-C 6 mg/m2, vinblastine 6 mg/m2 and cisplatin 60 mg/m2, repeated every 3 to 4 weeks. The median age of patients was 49 years (range, 35-71 yr). All patients had clinically measurable or evaluable disease and a Karnofsky's performance status greater than or equal to 50%. The median number of prior chemotherapy regimens was two (range, 1-4). Eighteen (94.7%) patients had previously received an anthracycline/anthracenedione-containing regimen, and seven (36.9%) had progression of disease during these therapies. Sixteen patients had two or more sites of metastasis and 17 patients had visceral disease. The median duration of follow-up was 26 months. A mean of 3.5 courses (range, 1-7) was administered. One patient was lost to follow-up after one course of treatment. Of the remaining 18 patients, two complete and five partial responses were observed, for a total response rate of 37% (range, 17-61%, 95% CI). One of the partial responders had disease progression during anthracycline treatment. Treatment-related toxicities were relatively well tolerated. There were no treatment-related deaths. The median duration of response was 3 months (range, 2-11 mo). The median overall survival was 7 months (range, 1-32 mo). Our data suggest that the MVP regimen is an effective palliative treatment for patients with refractory metastatic breast cancer.
