Colorectal Cancer: Surveillance
The majority of patients with colon and rectal cancer undergo curative resection and become candidates for surveillance.
The risk of colorectal cancer recurrence is largely dependent on the stage of disease at initial presentation, and the appropriate level of postoperative surveillance should reflect this degree of risk stratification.
In theory, proper surveillance allows subsequent polyps to be removed before malignant transformation occurs and improves survival by early identification of treatable recurrent cancer. Furthermore, surveillance directs family members of patients with hereditary cancers to receive proper screening and genetic counseling.
