Abstract
BACKGROUND: Advanced gastric cancer has a poor prognosis, with a relative 5-year survival rate of 7%-27%. Chemotherapy, which improves overall survival (OS) and quality of life, is the main treatment option. Although numerous regimens have been investigated, there is no standard treatment. Combination chemotherapy, however, is associated with a significant survival benefit compared with monotherapy and i.v. 5-fluorouracil (5-FU) is one of the most widely used agents. UFT (tegafur-uracil) has similar efficacy to continuous infusion 5-FU with improved tolerability and is more convenient for patients. DESIGN: The efficacy and safety of UFT in the treatment of advanced gastric cancer have been demonstrated in a number of phase II studies. RESULTS: UFT with leucovorin (folinic acid) monotherapy shows overall response rates (ORRs) of 16%-29% and median OS of 5.8 months. Combination of UFT with cisplatin, etoposide, or paclitaxel shows ORRs of 35%-51% and median OS of 8.3-10.1 months. UFT-based three-drug combinations show ORRs of 41%-57% and median OS of 8.6-15 months. UFT-based combinations have a good tolerability profile, particularly a low incidence of myelosuppression, mucositis, and hand-foot syndrome. CONCLUSION: UFT represents a logical replacement for 5-FU in chemotherapy regimens for the treatment of advanced gastric cancer.
