Purpose: In this study we evaluated the activity and toxicity of a combination of 5-fluorouracil continuous infusion and vinorelbine as second or third line chemotherapy in metastatic breast cancer (MBC). PATIENTS AN METHODS: A total 24 patients who had received doxorrubicin and/or paclitaxel were included in this study. The regimen consisted in 5-fluorouracil 1 gr/m(2) BSA continuous infusion for 3 days and vinorelbine 30 mg/m(2) intravenous (IV) on day 1. The cycles were repeated every 21 days for 6 cycles.
Results: Objective responses were recorded in 37.5% (12.5% complete remission). The median disease-free survival was calculated 6.33 +/- 8.12 months (CI 95% of 3.43 months). Toxicity was observed in 12.5% of the patients and no treatment related deaths were recorded.
Conclusion: The combination of 5-fluorouracil/vinorelbine at the dose administered is an effective regime in patients with MBC, with low toxicity and cost.
