Phase II trial of weekly intravenous gemcitabine with continuous infusion fluorouracil in patients with metastatic renal cell cancer.
Journal of Clinical Oncology 2000 June
PURPOSE: To determine the clinical response rate of the combination of weekly intravenous (IV) gemcitabine with continuous infusion fluorouracil (5-FU) in patients with metastatic renal cell carcinoma (RCC).
PATIENTS AND METHODS: Between June 1998 and February 1999, 41 patients with metastatic RCC were enrolled onto this multi-institutional phase II study of gemcitabine 600 mg/m(2) over 30 minutes on days 1, 8, and 15 and 5-FU 150 mg/m(2)/d via continuous IV infusion through a permanent catheter on days 1 to 21 of a 28-day cycle. Patients had a Cancer and Leukemia Group B performance status of 0 or 1, with a median time since diagnosis of metastatic disease of 10 months (range, 0 to 129 months). Thirty-three patients (80%) had multiple metastatic sites, and 34 patients (83%) had prior chemotherapy or immunotherapy.
RESULTS: Of the 39 assessable patients, there were no complete responses but seven partial responses (objective response rate = 17%; 95% confidence interval, 8% to 34%). Five minor responses (25% to 50% decreased tumor size) were also observed. The duration of response for the seven partial responders was 2, 3, 7, 8, 10, 11, and 14 months. Median progression-free survival for the gemcitabine/5-FU group was 28.7 weeks versus 8 weeks for a similar cohort of patients treated on previous phase II studies at the University of Chicago (P =.008). The regimen was well tolerated, with fatigue, mucositis, nausea/vomiting, and grade 2 hematologic toxicities being most common.
CONCLUSION: Weekly gemcitabine with continuous infusion 5-FU is an active combination in patients with metastatic RCC. Therapy was well tolerated and produced an improvement in progression-free survival over historical controls.
