PURPOSE: To evaluate the toxicity and efficacy of combination chemotherapy with paclitaxel and gemcitabine in patients with advanced transitional-cell carcinoma of the urothelial tract. PATIENTS AND METHODS: Fifty-four patients with advanced unresectable urothelial carcinoma entered this multi-centered, community-based, phase II trial between May 1997 and December 1999. All patients were treated with paclitaxel 200 mg/m(2) by 1-hour intravenous (IV) infusion on day 1 and gemcitabine 1,000 mg/m(2) IV on days 1, 8, and 15; courses were repeated every 21 days. Patients who had objective response or stable disease continued treatment for six courses. RESULTS: Twenty-nine of 54 patients (54%; 95% confidence interval, 40% to 67%) had major responses to treatment, including 7% complete responses. With a median follow-up of 24 months, 16 patients (30%) remain alive and nine (17%) are progression-free. The median survival for the entire group was 14.4 months; 1- and 2-year actuarial survival rates were 57% and 25%, respectively. Seven (47%) of 15 patients previously treated with platinum-based chemotherapy responded to paclitaxel/gemcitabine. Grade 3/4 toxicity was primarily hematologic, including leukopenia (46%), thrombocytopenia (13%), and anemia (28%). Ten patients (19%) required hospitalization for neutropenia and fever, and one patient had treatment-related septic death. CONCLUSION: The combination of paclitaxel and gemcitabine is active and well tolerated in the first- or second-line treatment of patients with advanced transitional-cell carcinoma of the urothelial tract. Response rate and duration compare favorably with those produced by other active, first-line regimens. This regimen should be further evaluated in phase II and III studies, as well as in patients with compromised renal function.
