ABSTRACT
Colorectal cancer is the second leading cause of cancer-related death in the United
States. Screening and surveillance for colorectal cancer are becoming more widespread,
which accounts for the decreased incidence of colorectal cancer in the last decade.
Endoscopic resection of adenomatous polyps has been shown to significantly decrease
the incidence of colorectal cancer. The follow-up of patients after removal of adenomatous
polyps is imperative as many of these patients still have a significant risk of developing
colorectal cancer. For patients with adenomas found on an index colonoscopy, a repeat
examination should be performed in 3 years. The age of the patient, number of polyps
discovered, size of the polyps, family history, and histology of polyps are all important
factors in defining the surveillance interval. In patients with numerous polyps, large
polyps, and malignant polyps the surveillance interval should be less than 3 years.
Surveillance programs need to be individualized to patients' underlying medical conditions
and risk of colorectal cancer.
