Core Tip

Core tip: Despite the fact that the incidence of colorectal cancer (CRC) in individuals less than 50 years seems to have increased in the last decade, there are very few data on adenoma and advanced neoplasia in this age group. This is the first large study to evaluate the adenoma detection rate (ADR) and advanced neoplasia detection rate (ANDR) in patients under 50 years during routine colonoscopy in average-risk and high-risk CRC patients. This study showed a significant two-fold increase in the ADR and ANDR in patients aged 45 years and older, irrespective of a personal or family history of polyps or cancer. Such high rates in those aged 45 years and over should be taken into account in CRC screening campaigns.
