Methods： Three-weekly regimen consisted of mitomycin, 6 mg/m^2 administered intravenously on day 1, and cisplatin, 25 mg/m^2 intravenously on day 1-3. Results： Thirty-eight patients aged 25-75 years （median, 46 years） were treated with an overall response rate of 31.6%. The median time to progression （TTP） was 4.0 months. Median TTP for 12 patients with a complete or partial response was 9.0 months, while stable disease and progression of disease 4.0 months, P=0.002. Grade 3/4 side effects of neutropenia, thrombocytopenia and nausea/vomiting were documented in 4 （10.5%）, 4 （10.5%） and 3 （7.9%） patients, respectively. The median overall survival was 13＊ months. Conclusion： Mitomydn C/cisplatin doublet showed antitumor activity for anthracydine-, vinorelbine- and taxane-resistant breast cancer comparable to other regimens. This well-tolerated regimen provides an affordable option for patients in China.展开更多
