BACKGROUND: Limited data exist on @entity652 as recommended in the European guidelines for quality assurance in @entity14 ( @entity14 ) screening and diagnosis after @entity1503 ( @entity1503 ) screening. OBJECTIVE: To assess the European guidelines for @entity652 after @entity14 screening with @entity1503 . MATERIALS AND METHODS: This was a population-based cohort-study of 176   782 Danish individuals aged 50-74 years invited for @entity14 screening in 2005-2006. @entity652 @entity1 were stratified into risk groups (low A, medium B, high C) in accordance with the European guidelines and followed up for recurrence of new @entity5 until the end of 2011. Risk ratios (RR) between the risk groups were calculated to assess differences in the recurrence rates of @entity5 . RESULTS: Among 84   803 screening @entity1 , 2059 had positive @entity1503 , of whom 1861 underwent colonoscopy, and 709 @entity1 had screen-detected @entity652 . During a median follow-up period of 72.7 months, detection of new advanced @entity652 (B+C) was significantly higher in risk group C than group A (RR 2.25, 95% confidence interval: 1.13-4.48). Nine @entity1 were diagnosed with @entity14 : one in risk group A, two in B and six in C. The detection rate of @entity14 was higher in risk group C than A (RR 5.20, 95% confidence interval: 0.63-42.58), but not statistically significant. In risk group C, half of new advanced @entity652 were detected within the first year and four of nine @entity14 were detected within 3 years. CONCLUSION: Risk stratification of @entity652 @entity1 , as recommended by the European guidelines, is appropriate for postpolypectomy surveillance after @entity1503 screening.
