A phase II study of doxifluridine and docetaxel combination chemotherapy for advanced or recurrent gastric cancer

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/m(2) per day on days 1-14 and an intravenous infusion of docetaxel 50 mg/m(2) 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.
