Postcolonoscopy colorectal cancer rates: monitoring and reducing the worst-case scenario

Colorectal cancer (CRC) screening through the detection and removal of adenomatous polyps during colonoscopy leads to over 50% reduction in mortality from CRC.1 Conversely, it is also evident that a significant portion of  CRC cases are diagnosed relatively soon after a colonoscopy that supposedly cleared the colon from premalignant adenomas and neoplasia. The predisposition for these interval cancers (I-CRCs) to the right side of the colon is not surprising when we consider the numerous studies that have shown less protection against right-sided CRC because I-CRCs are at least twice as likely to be found in the proximal, rather than the distal, colon.
