Association of Smoking and Flat Adenomas: Results from an Asymptomatic Population Screened with A High Definition Colonoscope

摘要

BackgroundFlat adenomas represent a morphologically distinct class of polyps that may be difficult to detect but little is known regarding risk factors for these lesions. Identification of risk factors for these lesions may aid in colorectal cancer (CRC) screening since patients at risk for these lesions may require special imaging techniques. Smoking, an important risk factor for CRC, may be associated with molecular changes that increase the risk for flat adenomas.
