Capecitabine is converted to 5-fluorouracil by thymidine phosphorylase, and mitomycin C is capable of upregulating the expression of thymidine phosphorylase suggesting a synergistic effect. Fifty-three patients (median age 62 years) with anthracycline- and taxane-resistant, metastatic breast cancer received mitomycin C 6 mg/m(2) on day 1, and capecitabine (Xeloda) 2,000 mg/m(2)/day from day 1 to day 14 with cycles repeated every 4 weeks. Overall, 77.4% had visceral metastases and 33 were pretreated with >/=3 chemotherapy lines. A median of 6 cycles were given (range 1-19) with a complete response observed in 2 patients (3.9%), partial response in 17 (33.3%) and stable disease in 19 (37.2%). Overall response rate was 37.2% (95% CI, 24.0-50.5%), with a median duration of 10.4 months. Median time to progression was 8.1 months and median survival was 17.4 months (1- and 2-year survival rates of 60 and 28%, respectively). Toxicity was mild. The most frequent grade 3/4 events were neutropenia (5.7% of patients), diarrhea (3.8%), and deep venous thrombosis (3.8%). Capecitabine plus mitomycin C may represent an effective and manageable treatment option for advanced breast cancer patients resistant to anthracyclines and taxanes. This approach provides an alternative for pretreated patients with advanced breast cancer.
