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.
- Evaluate the efficacy of reinforced versus standard follow-up care and the utility of follow-up CEA assessments in patients with fully resected stage II or III colorectal cancer.
OUTLINE: This is a multinational/multicenter study. Patients are randomized to 1 of 2 follow-up arms.
- Standard follow-up: Patients undergo clinical assessments every 3 months until year 3 and every 6 months until year 5. They are then assessed at least yearly thereafter. Patients undergo abdominal ultrasound every 3 months until year 3 and then every 6 months until year 5; chest x-ray every 6 months until year 3 and then annually until year 5; and colonoscopy at 3 years after surgery then every 3 to 6 years thereafter.
- Reinforced follow-up: Patients undergo clinical assessments every 3 months until year 3 and every 6 months until year 5. They are then assessed at least yearly thereafter. Patients undergo alternate assessments every 3 months comprising thoraco-abdomino-pelvic CT scan or abdominal ultrasound until year 3 and then every 6 months until year 5. They also undergo colonoscopy at 3 years after surgery then every 3 to 6 years thereafter.
Patients undergo a second randomization to 1 of 2 follow-up arms at the beginning of the study.
- CEA measurement: Patients undergo measurement of CEA levels every 3 months until year 3, every 6 months until year 5, and at least yearly thereafter.
- No CEA measurement: Patients do not undergo CEA measurement. Blood and tissue blocks of normal and tumor tissues are collected for the validation of protein serum, genetics, or immunologic markers predictive for relapse.

An imaging technique using a device which combines TOMOGRAPHY, EMISSION-COMPUTED, SINGLE-PHOTON and TOMOGRAPHY, X-RAY COMPUTED in the same session.
Computed tomography where there is continuous X-ray exposure to the patient while being transported in a spiral or helical pattern through the beam of irradiation. This provides improved three-dimensional contrast and spatial resolution compared to conventional computed tomography, where data is obtained and computed from individual sequential exposures.
Commercially prepared reagent sets, with accessory devices, containing all of the major components and literature necessary to perform one or more designated diagnostic tests or procedures. They may be for laboratory or personal use.
Computed tomography modalities which use a cone or pyramid-shaped beam of radiation.
Tomography using x-ray transmission and a computer algorithm to reconstruct the image.
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
