Editor's Note

A meta-analysis of 11 studies showed a significant association between patients who had a colonoscopy with nonmalignant findings and reductions in colorectal cancer and mortality rates.

Cancer rate reductions were greater for screening colonoscopy than for diagnostic colonoscopy, and results were similar for men and women.

One explanation for the lower cancer rates is the removal of all detected polyps during screening colonoscopy; another is that patients with negative colonoscopy findings are inherently associated with lower risks of developing cancer.

The findings provide additional evidence for the effectiveness of colonoscopy in the general population, the authors say.
