BackgroundThe objective of the current study was to evaluate the efficacy and toxicity of combination chemotherapy with paclitaxel, carboplatin, and gemcitabine in patients with advanced urothelial carcinoma.MethodsPatients with metastatic or locally unresectable transitional cell carcinoma of the urothelium who had received either no or one previous systemic chemotherapy regimen were eligible. All patients received chemotherapy with intravenous paclitaxel at a dose of 200 mg/m(2) on Day 1, intravenous carboplatin at an area under the serum concentration-time curve of 5.0 on Day 1, and intravenous gemcitabine at a dose of 1000 mg/m(2) on Days 1 and 8. Treatment courses were repeated every 21 days. Patients were evaluated for response after they completed two treatment courses; patients who achieved an objective response and stable disease continued treatment for a total of six courses or until tumor progression.ResultsSixty patients were treated between January 2000 and September 2003. Thirty-five patients (58%) had > or = 1 visceral sites of metastases, and only 4 patients (7%) had received any previous systemic chemotherapy. Twenty-six patients (43%) had achieved objective responses to treatment (12% complete responses). The median actuarial survival was 11 months, and the actuarial 1-year and 2-year survival rates were 46% and 27%, respectively. Myelosuppression was the most frequent toxicity, and Grade 3-4 neutropenia (using the National Cancer Institute Common Toxicity Criteria [version 2.0]) occurred in 72% of patients (46% of courses). Ten patients were hospitalized for the treatment of neutropenia and fever, and 1 patient died of treatment-related causes. Nonhematologic toxicities were relatively uncommon.ConclusionsThe combination of paclitaxel, carboplatin, and gemcitabine was an active and tolerable regimen for patients with advanced urothelial carcinoma. However, the regimen was more toxic and showed no obvious incremental increase in efficacy compared retrospectively with various two-drug regimens.
