Amanda J. Cross et al. Post-polypectomy surveillance interval and advanced neoplasia
detection rates: a multicenter, retrospective cohort study
Detection rates of colorectal neoplasia at surveillance among low and high risk patients,
according to time to first surveillance colonoscopy, were examined in this UK study.
Among low risk patients, metachronous advanced neoplasia was uncommon, even with longer
surveillance intervals of up to 6 years. Among high risk patients, the likelihood
of detecting advanced adenomas and colorectal cancer increased with increasing interval
length, particularly as the interval extended beyond 3 years. The findings support
a 3-year surveillance interval for high risk patients.
