PURPOSE: To determine the efficacy and toxicity of docetaxel in patients with müllerian carcinoma resistant to paclitaxel.
PATIENTS AND METHODS: Thirty-two patients with epithelial ovarian cancer, fallopian tube cancer, or primary peritoneal cancer who failed paclitaxel-based chemotherapy received either 100 or 75 mg/m(2) of docetaxel every 3 weeks. Resistance to paclitaxel was defined as either progression of disease during treatment, failure to achieve regression of disease after at least four courses, or rapid recurrence (within 6 months) after completion of therapy.
RESULTS: Eighteen patients were treated on a formal protocol and fourteen with the commercially available docetaxel. Thirty were assessable for response. Toxicities were thoroughly evaluated in the 18 patients on protocol. Twenty-seven patients (85%) had epithelial ovarian cancer. The overall response rate was 23% (one complete and six partial responses), with a median survival time of 44 weeks (9.5 months). Nine patients had stable disease and 14 progressive disease. Among 19 patients who progressed during prior paclitaxel treatment, two (11%) responded to docetaxel, compared with five (45%) of 11 patients in other paclitaxel-resistance categories. The responders had a median taxane-free interval (ie, the time between the last paclitaxel and first docetaxel treatment) of 73 weeks, compared with 19 weeks for the nonresponder group. Toxic effects were as expected.
CONCLUSION: Docetaxel is an active chemotherapeutic agent in patients with müllerian carcinoma previously treated with paclitaxel-based chemotherapy, especially in the patients who had a long taxane-free interval after a previous short response to paclitaxel.
