A Phase II Study of Docetaxel and Oxaliplatin for Second-Line Treatment of Urothelial Carcinoma

À¶Ý®ÊÓƵ

Abstract

Despite high response rates with front-line platinum-based therapies, 80% of patients with metastatic urothelial cancer progress. Multiple agents and couplets have been investigated, but no standard second-line regimen exists. We conducted a phase II study to evaluate the efficacy and safety of docetaxel and oxaliplatin in metastatic urothelial cancer patients who had received prior platinum therapy.Patients with metastatic urothelial cancer, who had disease progression after platinum therapy, were treated with docetaxel 75 mg/m(2) and oxaliplatin 85 mg/m(2) every 3 weeks until disease progression or intolerable toxicity.Between November 2004 and September 2005, 11 patients were enrolled. All patients had low or intermediate Bajorin risk. The median number of cycles administered was 2 (range 2-8). One patient achieved near complete response. Three patients experienced disease stabilization, resulting in a disease-control rate of 36%. Median overall survival was 7 months. The most common toxicities were fatigue and anemia (50%).Second-line docetaxel and oxaliplatin in metastatic urothelial cancer is safe and tolerable but did not achieve an appreciable response rate.
