Condition colorectal cancer
Treatments folinate calcium, tegafur-uracil, tegafur-gimeracil-oteracil potassium
Phase phase 3
Sponsor Translational Research Informatics Center, Kobe, Hyogo, Japan
Start date April 2008
End date June 2012
Trial size 1535 participants
Trial identifier NCT00660894, CDR0000593164, TMDU-TRICC0706


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 purpose treatment
Patients receive tegafur-gimeracil-oteracil potassium(S-1) orally twice daily for 28 days with a subsequent pause of 14 days. This repeats 4 times every 6 weeks.

(Active Comparator)
Patients receive tegafur-uracil(UFT) plus folinate calcium(leucovorin) orally every 8 hours for 21 days with a subsequent pause of 7 days. This repeats 5 times every 5 weeks.

Principal investigator Kenichi Sugihara, MD, PhD
Description OBJECTIVES: - Compare the disease-free survival of patients with stage III colon cancer treated with S-1 or tegafur-uracil and leucovorin after curative surgery . OUTLINE: Patients are randomized to 1 of 2 treatment arms. - Arm I: Patients receive oral tegafur-uracil and oral leucovorin 3 times daily on days 1-21. The treatment repeats 5 times every 5 weeks. - Arm II: Patients receive oral S-1 twice daily on days 1-28. The treatment repeats 4 times every 6 weeks. Biological samples are collected for gene expression analysis for identification of predictive markers.
