[Efficacy of docetaxel for anthracycline-resistant metastatic breast cancer]

From June 1997 through December 1999, we treated twenty-two metastatic breast cancer patients with Docetaxel (60 mg/m2 administered intravenously every four weeks). All patients had received prior chemotherapy including anthracycline, and also another agent such as MMC-VDS, HDMTX-5-FU or CPT-11. One CR, 5 PR, and 4 Long NC were achieved. Grade 3/4 leukocytopenia occurred in 16 patients. Using the Kaplan Meier method, the median time to progression was 179 days, and the median survival time was 369 days. No serious adverse effects were observed. In this study Docetaxel seems to have shown significant activity, even for poor candidates, with intensive prior therapy.
