RATIONALE: Diagnostic procedures, such as ultrasound, x-ray, colonoscopy, CT scan, and CEA assessment, may help monitor a patient's response to surgery. It is not yet known which follow-up regimen is more effective in patients who have undergone surgery for colorectal cancer.
PURPOSE: This randomized phase III trial is comparing two types of follow-up care with or without CEA assessments to see how well they work in patients who have undergone surgery for stage II or stage III colorectal cancer.
