Adenoma Detection Rate: Lowering Colorectal Cancer Risk

Adenoma detection rate is a recognized colonoscopy quality measure. In a recent study published in the New England Journal of Medicine, researchers set out to determine the association between ADR and subsequent colorectal cancer and mortality.

The researchers studied 314,872 colonoscopies performed by 136 gastroenterologists. ADRs ranged from 7.4 percent to 52.5 percent. During the follow-up period, 712 interval colorectal adenocarcinomas were identified, 255 of which were advanced-stage cancers.

Each 1 percent increase in ADR was associated with a 3 percent decrease in the risk of colorectal cancer.
