RESUMEN

PURPOSE: The combination of gemcitabine plus cisplatin (GC) is a standard regimen in patients with locally advanced or metastatic urothelial cancer. A phase I/II study suggested that a three-drug regimen that included paclitaxel had greater antitumor activity and might improve survival. PATIENTS AND METHODS: We conducted a randomized phase III study to compare paclitaxel/cisplatin/gemcitabine (PCG) with GC in patients with locally advanced or metastatic urothelial carcinoma. Primary outcome was overall survival (OS). Secondary outcomes were progression-free survival (PFS), overall response rate, and toxicity. RESULTS: From 2001 to 2004, 626 patients were randomly assigned; 312 patients were assigned to PCG, and 314 patients were assigned to GC. After a median follow-up of 4.6 years, the median OS was 15.8 months on PCG versus 12.7 months on GC (hazard ratio [HR], 0.85; P = .075). OS in the subgroup of all eligible patients was significantly longer on PCG (3.2 months; HR, 0.82; P = .03), as was the case in patients with bladder primary tumors. PFS was not significantly longer on PCG (HR, 0.87; P = .11). Overall response rate was 55.5% on PCG and 43.6% on GC (P = .0031). Both treatments were well tolerated, with more thrombocytopenia and bleeding on GC than PCG (11.4% v 6.8%, respectively; P = .05) and more febrile neutropenia on PCG than GC (13.2% v 4.3%, respectively; P < .001). CONCLUSION: The addition of paclitaxel to GC provides a higher response rate and a 3.1-month survival benefit that did not reach statistical significance. Novel approaches will be required to obtain major improvements in survival of incurable urothelial cancer.

RESUMEN

PURPOSE: To evaluate the safety and efficacy of intravenous (IV) sodium ferric gluconate complex (FG), oral ferrous sulfate, or no iron to increase hemoglobin (Hb) in anemic cancer patients receiving chemotherapy and epoetin alfa. PATIENTS AND METHODS: In this open-label, multicenter trial, 187 patients with chemotherapy-related anemia (Hb <11 g/dl; serum ferritin > or =100 ng/ml or transferrin saturation > or =15%) scheduled to receive chemotherapy and epoetin alfa (40,000 U subcutaneously weekly) were randomized to 8 weeks of 125 mg of IV FG weekly, 325 mg of oral ferrous sulfate three times daily, or no iron. The primary outcome was a change in Hb from baseline to endpoint, first whole-blood or red blood cell transfusion, or study withdrawal. RESULTS: One hundred twenty-nine patients were evaluable for efficacy (FG, n = 41; oral iron, n = 44; no iron, n = 44). Mean increase in Hb was 2.4 g/dl (95% confidence interval [CI], 2.1-2.7) for FG (p = .0092 vs. oral iron; p = .0044 vs. no iron), 1.6 g/dl (95% CI, 1.1-2.1) for oral iron (p =.7695 vs. no iron), and 1.5 g/dl (95% CI, 1.1-1.9) for no iron. Hb response (increase > or =2 g/dl) was 73% for FG (p = .0099 vs. oral iron; p = .0029 vs. no iron), 46% for oral iron (p = .6687 vs. no iron), and 41% for no iron. FG was well tolerated. CONCLUSION: For cancer patients with chemotherapy-related anemia receiving epoetin alfa, FG produces a significantly greater increase in Hb and Hb response compared with oral iron or no iron, supporting more aggressive treatment with IV iron supplementation for these patients.

RESUMEN

INTRODUCTION: This study was designed to define the maximum tolerated dose of pegylated liposomal doxorubicin (Doxil) and multiday vinorelbine (VNB), without and with prophylactic filgrastim, and to identify antineoplastic effect. PATIENTS AND METHODS: Patients with resistant cancers were treated with Doxil 50 mg/m2 every four weeks, and with VNB 15 mg/m2 on the same day. The VNB dose escalations were accomplished in subsequent patient cohorts by adding VNB doses on consecutive days. When the maximum tolerated dose (MTD) of VNB with Doxil was defined, prophylactic filgrastim was added to define a second MTD. RESULTS: Of 29 patients entered, two had early adverse events, and 27 received at least one full cycle with at least one month follow-up. The MTD of VNB, combined with Doxil 50 mg/m2, was 15 mg/m2 on day 1, with neutropenia as the dose-limiting toxicity. With prophylactic filgrastim, the MTD was 15 mg/m2 daily for two days, with neutropenia and stomatitis as dose-limiting toxicities. Palmar plantar erythrodysesthesia occurred frequently, usually after the third cycle. Objective responses were documented in six patients, all of whom received multiday VNB. CONCLUSION: Doxil 50 mg/m2 on day 1 of a 28-day cycle can be safely combined with VNB 15 mg/m2 day 1, or with VNB 15 mg/m2 days 1 and 2 with filgrastim prophylaxis. Antineoplastic activity was observed in this heavily pretreated population. Future studies of Doxil 35-40 mg/m2 with multiday VNB may be worthwhile, especially in metastatic breast cancer.
