ReviewPost-treatment surveillance in colorectal cancer patients: how to do it? A comprehensive review.
Patients who undergo a potentially curative treatment of colorectal cancer are at risk of local recurrences, distant metastases, and metachronous neoplasms. Accordingly, these patients typically undergo a multimodal oncological surveillance aimed to detect relapses early, with an expectation of a higher rate of radical retreatments and better overall survival. ⋯ Typical surveillance recommended by guidelines includes regular physical examinations, computed tomography scans, serum carcinoembryonic antigen monitoring, and colonoscopy. The objective of this comprehensive review is to discuss different patterns of relapses observed in colorectal cancer patients, present diagnostic options, and summarize different strategies and recommendations of the posttreatment surveillance.
