RATIONALE: Drugs used in chemotherapy, such as tegafur-uracil, leucovorin, and S-1, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether giving tegafur-uracil together with leucovorin is more effective than giving S-1 in treating patients with stage III colon cancer.

PURPOSE: This randomized phase III trial is studying giving tegafur-uracil together with leucovorin to see how well it works compared with giving S-1 in treating patients with stage III colon cancer that has been completely removed by surgery.

Primary Outcome Measures:
  • Disease-free survival [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Overall survival [ Designated as safety issue: No ]
  • Adverse event [ Designated as safety issue: Yes ]
  • Pharmaco-economics [ Designated as safety issue: No ]

Estimated Enrollment: 1480
Study Start Date: April 2008
Estimated Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Detailed Description:


  • Compare the disease-free survival of patients with stage III colon cancer treated with S-1 or tegafur-uracil and leucovorin calcium after curative surgery .

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients receive oral tegafur-uracil and oral leucovorin calcium 3 times daily on days 1-21. Treatment repeats every 5 weeks for up to 5 courses.
  • Arm II: Patients receive oral S-1 twice daily on days 1-28. Treatment repeats every 6 weeks for up to 4 courses.

Biological samples are collected for gene expression analysis for identification of predictive markers.
