Adenoma Detection Rate after Positive Stool-Based Screening in a U.S. Population

Abstract

Introduction and Objectives Over the past two decades, advancements in screening programs have led to a decrease in the incidence and mortality rates of colorectal cancer. The recommended benchmark for primary screening colonoscopy adenoma detection rate (ADR) is 25%. However, recent research supports higher ADR benchmarks following positive stool testing. Findings from a Dutch screening program have suggested higher ADRs in fecal immunochemical test positive patients with an inverse relationship with interval cancer development. Our study aims to assess ADRs in a U.S. patient population with positive stool screenings and investigate any correlation to occurrences of interval cancers.
