    Abstract:
    PURPOSE: Capecitabine and paclitaxel show high efficacy, non-overlapping toxicity profiles and preclinical synergism, providing the rationale for their combination in metastatic breast cancer (MBC). This dose-escalation study aimed at determining the maximum tolerated dose (MTD) of capecitabine plus paclitaxel in anthracycline-pretreated MBC patients. PATIENTS AND METHODS: Patients with MBC received fl at-dose of oral capecitabine (1,000 mg/m(2) twice daily, days 1-14) plus weekly paclitaxel 60, 75, or 90 mg/m(2), i.v., days 1, 8 and 15, every 3 weeks. RESULTS: All 11 patients enrolled onto study were evaluable for toxicity and response. Two patients receiving paclitaxel 75 mg/m(2) experienced grade 3 nail toxicity, with grade 3 hand-foot syndrome (HFS) in one patient and grade 2 dermatitis in the other. Although not life-threatening, these were considered unacceptable and the preceding dose level was selected. Eight of 11 patients achieved objective responses. CONCLUSION: The recommended regimen is capecitabine 1,000 mg/m(2) twice daily, days 1-14, plus paclitaxel 60 mg/m(2)/week. Escalation of the paclitaxel dose above 60 mg/m(2)/week is not feasible due to severe skin toxicity.
