It is essential to determine the need for subsequent colonoscopy follow-up evaluation after flexible sigmoidoscopy screening. Although there are some prediction models of advanced proximal neoplasia (APN) in Western countries, they were found to be limited in Asian population. In the analysis “Development and Validation of the Asia-Pacific Proximal Colon Neoplasia Risk Score”, a scoring system to identify people at risk for APN was developed and validated from 14 Asia-Pacific study sites. This score consisted of age, smoking habits, colorectal cancer family history and the presence of neoplasia in the distal colorectum. Screening candidates with a score of 4 or above should be referred for colonoscopy examination. (Clin Gastroenterol Hepatol. 2020 Jan 7. pii: S1542-3565(20)30004-5. doi: 10.1016/j.cgh.2019.12.031.
