No benefit of more intense follow-up after surgery for colorectal cancer in the risk group with elevated CEA levels – An analysis within the COLOFOL randomized clinical trial
Background: Patients with colorectal cancer were examined to determine (1) whether elevated carcinoembryonic antigen (CEA) levels, either before treatment or after surgery, was associated with an increased risk of overall or colorectal cancer-specific mortality or recurrence, and (2) whether high intensity follow-up would benefit those patients.
