Purpose: We evaluated the efficacy and toxicity of weekly paclitaxel in patients with previously treated advanced urothelial cancer. Patients and Methods: Patients with urothelial cancer who had received one prior systemic chemotherapy regimen for advanced disease and had evidence of disease progression were eligible for enrollment. Patients received paclitaxel 80 mg/m2 by 1-hour intravenous infusion weekly. A cycle of therapy consisted of four weekly treatments. Results: The study enrolled 31 patients. Mean age was 66 years, and 45% of patients had three or more involved metastatic sites. Only 26% of patients had responded to prior chemotherapy. The median number of cycles delivered was three (range, one to eight) at a mean weekly paclitaxel dose of 79 mg/m2. Three patients achieved a partial response (10%; 95% confidence interval, 0% to 20%). Median time to progression was 2.2 months, and median overall survival time was 7.2 months. Therapy was well tolerated with minimal hematologic toxicity. Grade 3 nonhematologic toxicities were also uncommon. Conclusion: Although the overall response rate to weekly paclitaxel in patients with previously treated advanced urothelial cancer was modest, the chemotherapy-refractory nature of the study population should be considered.
