Docetaxel, a promising novel chemotherapeutic agent in advanced breast cancer.
Clinical practice in chemotherapy of breast cancer is undergoing changes. This study investigated the efficacy and toxicity of docetaxel, a novel chemotherapeutic agent in metastatic breast cancer. Focus was on the effect of the cumulative dose of previous anthracycline treatment on response rate, toxicity and survival in our own patients; published data were reviewed. PATIENTS AND METHODS: Thirty-one women, (median age 52 years, range 40-65) treated for metastatic breast cancer with docetaxel were included. RESULTS: The overall response rate was 48%, with 3 complete and 11 partial responses (95% CI 29-66). The duration of response was 7 months (range 2 to 16 months), the median overall survival after docetaxel 13.7 months for responding patients, 14.3 months in no-change patients and 6.5 months in patients with progressive disease. The mean cumulative anthracycline dose prior to docetaxel was 860 mg (range 200-1760 mg); in the case of responders, the previous cumulative total epirubicin doses were 200-1575 mg (median 766 mg.). Total dose or schedule of previous epirubicin treatment had no impact on docetaxel response rate, toxicity or survival. The response seen in this study is within the published range (24 to 60%) observed for docetaxel in anthracycline-treated patients. CONCLUSION: We conclude that docetaxel is active in metastatic breast cancer even as third- line treatment. Previous treatment with, or response to, epirubicin does not influence the response to docetaxel and this promising new drug is currently being tested for adjuvant use in breast cancer.[1]References
