Abstract

The objective of this study was to evaluate the efficacy and toxicity of combination chemotherapy with paclitaxel, carboplatin and gemcitabine in patients with advanced urothelial carcinoma, who have received prior cisplatin-based chemotherapy. Eligible patients had pathologically proven measurable metastatic urothelial carcinoma. Between April 2005 and May 2009, 8 patients with a mean age of 7 0 years were treated every 3 weeks with paclitaxel (200 mg/m² on day 1), carboplatin (AUC= 5/body on day 1) and gemcitabine (800 mg/m² on day 1 and 8). A total of 4 0 (median 4) cycles were administered. None of the 8 patients achieved a complete response(CR), but 3 patients (37. 5%) achieved a partial response (PR) and 3 were stable with the disease(SD). The median overall survival time and the median progression-free survival time were 8. 0 and 4. 5 months, respectively. Grade 4 hematological toxicities included neutropenia in 6 cycles (15. 0%), thrombocytopenia in 8 cycles (20. 0%) and anemia in 11 cycles (27. 5%). Three of the 8 patients had febrile neutropenic episodes, and no toxic death was observed. Our results suggest that the combination chemotherapy of paclitaxel, carboplatin and gemcitabine was effective, and an acceptable treatment for patients with advanced urothelial carcinoma who have received prior cisplatin-based chemotherapy.
