PURPOSE: To evaluate the efficacy and toxicity of gemcitabine (2′,2′-difluorodeoxycytidine) plus cisplatin in previously untreated patients with advanced transitional-cell carcinoma. PATIENTS AND METHODS: Thirty-one patients with measurable advanced transitional-cell carcinoma who had received no prior chemotherapy for metastatic disease were scheduled to receive gemcitabine 1,000 mg/m2 intravenously over 30 minutes on days 1, 8, and 15 and cisplatin 70 mg/m2 over 1 hour on day 2 of a 28-day cycle. Prior adjuvant or neoadjuvant therapy for locally advanced disease was allowed if this was completed more than 1 year before study entry. RESULTS: There were six complete responses and 10 partial responses in 28 assessable patients, for anoverall response rate of 16 of 28 (57%). The response rate on an intent-to-treat basis was 16 of 31 patients (52%). The median survival is 13.2 months, with 18 patients still alive at this time. Toxicity was primarily hematologic, with 12 of 31 patients (39%) having ≥ grade 3 granulocytopenia and 17 of 31 (55%) having ≥ grade 3 thrombocytopenia. Two patients had febrile neutropenia. All patients required a dose modification of gemcitabine at some point in their therapy; the primary reason was thrombocytopenia and/or neutropenia. CONCLUSION: Gemcitabine plus cisplatin is an active regimen for the treatment of urothelial cancer.

PURPOSE To evaluate the efficacy and toxicity of gemcitabine (2',2'-difluorodeoxycytidine) in previously untreated patients with advanced transitional cell carcinoma. PATIENTS AND METHODS Forty-one patients with measurable advanced transitional cell carcinoma who had received no prior chemotherapy for metastatic disease were scheduled to receive gemcitabine 1,200 mg/m2 intravenously over 30 minutes on days 1, 8, and 15 of a 28-day cycle. Prior adjuvant or neoadjuvant therapy for locally advanced disease was allowed if this was completed greater than 1 year prior to study entry. All patients were treated on an outpatient basis. RESULTS There were three complete responses and six partial responses seen in 37 assessable patients, for an overall response rate of nine of 37 (24.3%; 95% confidence interval, 12 to 41). Four patients remain in remission at 14, 23, 24, and 31 months. The median survival was 8 months with 17% of patients alive at 2 years. Treatment generally was well-tolerated with three patients having > or = grade 3 nonhematologic toxicity, five having grade 3 neutropenia, two having grade 3 thrombocytopenia, and two episodes of febrile neutropenia. Most patients were able to receive the drug as scheduled with the primary reason for dose reduction or dose delay being neutropenia. CONCLUSION Gemcitabine has promising single-agent activity against urothelial cancer with a favorable toxicity profile. Further studies in combination with other active agents are warranted.

PURPOSE: To determine the maximum-tolerated dose and the antitumor activity of a combination of paclitaxel, cisplatin, and gemcitabine in advanced transitional-cell carcinoma (TCC) of the urothelium. PATIENTS AND METHODS: Patients with measurable, previously untreated, locally advanced or metastatic TCC and with Eastern Cooperative Oncology Group performance status ≤ 2 and creatinine clearance ≥ 55 mL/min were eligible. Cisplatin was given on day 1 at a fixed dose of 70 mg/m2. Paclitaxel and gemcitabine were given on days 1 and 8 at increasing dose levels. Cycles were repeated every 21 days to a maximum of six cycles. RESULTS: Sixty-one patients were registered. In phase I, 15 patients were entered at four different dose levels. Dose-limiting toxicity consisted of early onset (after the first cycle) grade 2 asthenia (two of six patients) and grade 3 asthenia (one of six patients) at dose level 4. A paclitaxel dose of 80 mg/m2 and gemcitabine 1,000 mg/m2 was recommended for phase II, and 46 additional patients were entered at this level for a total of 49 patients. Main nonhematologic toxicity was grade 2 asthenia in 18 patients, with early onset in five patients, and grade 3 in four patients. Grade 3/4 neutropenia and thrombocytopenia occurred in 27 (55%) and 11 (22%) patients, respectively. Overall, febrile neutropenia was seen in 11 patients, and one toxic death occurred because of neutropenic sepsis. The combination was active at all dose levels. In total, 58 of 61 eligible patients were assessable for response; 16 complete responses (27.6%) and 29 partial responses (50%) were observed for an overall response rate of 77.6% (95% confidence interval, 60% to 98%). The median survival time (MST) available for the phase I part of the study is 24.0 months. MST has not been reached for the whole group with the current follow-up. CONCLUSION: This combination of paclitaxel, cisplatin, and gemcitabine is feasible and highly active in patients with advanced TCC of the urothelium. Further evaluation of this regimen in patients with TCC is warranted.

PURPOSE To assess the efficacy and toxicity of single-agent paclitaxel as first-line chemotherapy in patients with locally advanced or metastatic transitional-cell carcinoma of the urothelium. PATIENTS AND METHODS Twenty-six eligible patients were enrolled onto this cooperative group study and treated with paclitaxel at a dosage of 250 mg/m2 by 24-hour continuous infusion every 21 days until progression or patient intolerance. All patients received recombinant human granulocyte colony-stimulating factor (rhG-CSF) at 5 micrograms/kg/d for at least 10 days during each cycle. RESULTS Eleven of 26 patients (42%; 95% confidence interval [CI], 23% to 63%) demonstrated an objective response, with seven achieving a complete clinical response (CR) (27%; 95% CI, 12% to 48%) and four (15%) a partial response (PR). The median duration of response in the 11 responders is 7+ months (range, 4 to 17), with five responders (four CRs, one PR) remaining progression-free at 5, 6, 10, 12, and 16 months from the start of therapy. The estimated median survival duration for all patients is 8.4 months. Hematologic toxicity consisted of anemia (12% grade 3) and granulocytopenia (4% grade 3, 19% grade 4), with two patients developing granulocytopenic fevers. Nonhematologic toxicity included grade 3 mucositis in 11%, grade 3 neuropathy in 11%, and grade 4 diarrhea in 4%. CONCLUSION Single-agent paclitaxel at this dosage and schedule is one of the most active single agents in previously untreated patients with advanced urothelial carcinoma, and is well tolerated by this patient population when given with hematopoetic growth factor support.
