Background The aim of this study was to establish the efficacy and safety of doxifluridine and docetaxel for patients with advanced or recurrent gastric cancer. Methods The regimen consisted of oral administration of doxifluridine 533 mg/m² per day on days 1-14 and an intravenous infusion of docetaxel 50 mg/m² on day 8. The primary endpoint was the overall response rate. The secondary endpoints were overall survival, progression-free survival, and toxicities. Results Between June 2004 and December 2006, a total of 40 eligible patients were enrolled in this study. Seven of them showed a partial response, with an overall response rate of 17.5%. The response rate was 18.8% in 32 patients with refractory tumors. The median progression-free survival time and the median overall survival time were 2.6 months and 12.7 months, respectively, in all 40 patients; and 2.6 months and 14.0 months, respectively, in the 32 patients with refractory tumors. Grade 3/4 hematological toxicity included neutropenia in 52.5%, leukocytopenia in 17.5%, and febrile neutropenia in 7.5%. Grade 3 or more nonhematological toxicities were infrequent. Conclusion The combination chemotherapy of doxifluridine and docetaxel was well tolerated and relatively effective when used as a second-line chemotherapy for advanced or recurrent gastric cancer.
