Objectives: We conducted a multicenter phase II study to evaluate the clinical effi cacy, toxicity, and dose intensity of a new weekly schedule of docetaxel and gemcitabine
as fi rst-line treatment of metastatic breast cancer patients. Methods: We enrolled 58 patients, 52% of whom had received a previous anthracycline-containing chemotherapy. The treatment schedule was: docetaxel
35 mg/m 2 and gemcitabine 800 mg/m 2 i.v. on days 1, 8,15 every 28 days. Results: All patients were assessable for toxicity and 56 for effi cacy. Overall response rate was
64.3% with 16.1% of complete responses and 48.2% of partial responses. Median survival was 22.10 months (95% CI: 15.53\u201328.67) and median time to tumor progression was 13.6 months (95% CI: 10.71\u201316.49). The most common hematological toxicity was neutropenia (no febrile
neutropenia), which occurred in 28 patients (48.3%) but grade 3\u20134 in only 8 patients (14%). Alopecia, the most common nonhematological toxicity, occurred in 20 (34.5%) patients, but only 5 patients (8.6%) experienced
grade 3 alopecia. Conclusion: The activity of docetaxel and gemcitabine in metastatic breast cancer is confirmed. The promising results of the employed schedule,in agreement with other published studies, need to be
further confirmed within a phase III study
