Abstract: | PURPOSE: To evaluate the efficacy and safety of docetaxel in heavily pretreated and anthracycline-resistant patients with metastatic breast cancer in an outpatient setting. PATIENTS AND METHODS: Between February 1996 and June 1998, 98 consecutive patients who had progressed during or relapsed following prior anthracycline-containing chemotherapy were enrolled into the trial. Docetaxel was administered at a dose of 100 mg/m2 by intravenous infusion every 3 weeks. The administration of colony-stimulating factors was at the discretion of the attending physician. Premedication with dexamethasone was mandatory for all patients. RESULTS: Of the 98 patients, 93 were evaluable for toxicity and response. Patients had received two palliative regimens (median, range 1-5) prior to docetaxel treatment. The most frequent toxicity observed was leukopenia grade III and IV (WHO grading system) which occurred in 47% of patients (grade IV only in 14%). Except for alopecia grade III (64% of patients), nonhematologic side effects grade III-IV were rare (1-7% of patients) and included nausea, stomatitis, diarrhea, peripheral neuropathy, fluid retention and pulmonary toxicities. There were no treatment-related deaths. Objective responses occurred in 40% of patients (CR 6%, PR 34%), and stable disease in 38% of patients. The median duration of response was 5.3 months (range 0.7-18.1 months) while the median survival was 15 months (range 2 36 months). CONCLUSION: Docetaxel is a highly active agent in patients with anthracycline-resistant metastatic breast cancer, even in heavily pretreated patients, with moderate toxicity. |
