Abstract

Purpose: The current study assessed the efficacy and safety of biweekly oxaliplatin combining oral tegafur-uracil/leucovorin in treating chemonaive patients with advanced gastric cancer. Methods: Eligible patients were 18-75 years old, had stage IV disease or post-surgery recurrence, no prior palliative chemotherapy, and an ECOG performance status of 0-2. Patients in the current study received 2-h i.v. infusion of oxaliplatin at a dose of 100 mg/m 2 after diluting in 500 mL 5% dextrose/water (dexan premedication), and 5-HT3 antagonist biweekly. Oral tegafur-uracil and leucovorin was given at a dose of 300 mg/m2/day and 60 mg/day three times daily from day 1 to 21, respectively, followed by a 1-week rest. Response assessment was based on the RECIST criteria and was performed every two courses. Toxicity was assessed according to NCI common toxicity criteria version 2. Results: From October 2003 to April 2006, 57 patients were evaluated (55 eligible) with a median age of 61 years (range 31-75). According to the assessment of response in 48 evaluable patients, partial response rate was 24/48 (50.0%) (95% CI: 35.23-64.73%) and stable disease was observed in 11 patients (22.92%), and diseased progressed in 13 patients (27.08%). Mean number of oxaliplatin cycles was 3 (0.5-6.5). Median time to progression was 177 days. Median overall survival was 318 days. Major-grade (III/IV) toxicities were diarrhea 25.5%, vomiting 16.5%, anemia 10.9%, numbness 12.7%, thrombocytopenia 7.3%, neutropenia 3.6% and leucopenia 1.8%. Conclusions: Biweekly, oxaliplatin combining oral tegafur-uracil/ leucovorin in treating patients with advanced gastric cancer showed acceptable activity and manageable toxicity.
