Combination Chemotherapy in Treating Patients With Resected Colon Cancer

• Status: Completed
• Trial end date: 2009-04-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug is a way to kill more tumor cells.

PURPOSE: Randomized phase III trial to determine the effectiveness of uracil, tegafur,and leucovorin compared with fluorouracil plus leucovorin in patients with resected stage II or stage III colon cancer.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: NSABP Foundation Inc
• Collaborator: National Cancer Institute (NCI)
• Treatments: Calcium; Fluorouracil; Leucovorin; Levoleucovorin; Tegafur
