Metachronous colon polyps in younger versus older adults: a case-control study

The incidence of colorectal cancer (CRC) in the United States has decreased substantially in individuals aged 50 and older. Contrariwise, it is increasing in young adults. The polyp characteristics on baseline and follow-up colonoscopy in young adults are not well characterized. We describe the polyp characteristics on baseline and follow-up colonoscopy in adults < 40 years and determined factors associated with the occurrence of metachronous, advanced neoplasia or high risk (HR) polyp features.
