Physician adenoma detection rates and risk of post-colonoscopy colorectal cancer in a sequential screening programme: a retrospective cohort study.

ABSTRACT:

Objectives

Long-term colorectal cancer (CRC) monitoring is common in Asia, but assessing colonoscopy effectiveness through adenoma detection rates (ADRs) remains uncommon. This study aimed to identify potential associations between ADR and risk of post-colonoscopy CRC (PCCRC).

Methods

This retrospective, longitudinal, observational study included participants (aged 40-74 years) with initial positive results and subsequent colonoscopy recruited from a community-based, multicentre, CRC screening programme from January 2012 to December 2022 in Tianjin, China. ADR was defined as the proportion of colonoscopies in which at least one adenoma was detected at the provider level. The primary outcome was PCCRC, defined as any CRC diagnosed 6 months after initial colonoscopy. ADR group
