Phase II Study of Capecitabine and Weekly Docetaxel Followed by Capecitabine Maintenance for Patients With Metastatic Breast Carcinoma

In this phase II study, we plan to evaluate the efficacy, safety and tolerability of weekly docetaxel and capecitabine on a 21-day cycle followed by maintenance single agent capecitabine for the treatment of metastatic breast cancer, Based on the efficacy and toxicity of the combination regimen dosages previously reviewed; weekly docetaxel 30mg/m2 on days 1 and 8 plus capecitabine 1600mg/m2 (800mg/m2 orally twice daily)on day 1 through 14 of each cycle will be utilized.
