BackgroundThe United Kingdom (U.K.) post-adenoma resection guidelines recommend earlier surveillance for patients with 5 or more adenomas or 3 to 4 adenomas of which one is 10 mm or larger compared with U.S. guidelines.ObjectiveTo evaluate the effect of using the U.K. guideline on a U.S. cohort of adenoma patients.DesignSingle-center, retrospective study.SettingIndiana University Hospital and an associated ambulatory surgery center.PatientsA total of 1414 patients with baseline adenoma findings belonging to one of 5 risk categories and with a follow-up colonoscopy more than 200 days later.InterventionColonoscopy, polypectomy.Main Outcome MeasurementsIncidence of advanced lesions at follow-up colonoscopy.ResultsAdvanced neoplasms at follow-up occurred in 16.3% of patients with 5 or more adenomas including 1 that was 10 mm or larger, 8.6% of patients with 3 or 4 adenomas including 1 that was 10 mm or larger, 5% of those with 5 or more adenomas all smaller than 10 mm, 1.8% of those with 3 or 4 adenomas all smaller than 10 mm, and 1.4% of those with 1 to 2 adenomas smaller than 10 mm. Logistic regression analyses showed that the rate of advanced lesions at first follow-up was increased in persons with 3 or more baseline adenomas and at least 1 that is 10 mm or larger compared with those with 1 to 4 small baseline adenomas.LimitationsSingle-center, retrospective study.ConclusionsOur results indicate the U.K. guideline predicts higher risk groups for advanced neoplasia at first follow-up. Our study had inadequate power to show better prediction of incident cancer. Additional study of other databases is warranted.
