Colorectal screening if colonic adenomas

Consensus guidelines have been developed by the British Society of Gastroenterology, the Association of Coloproctology of Great Britain and Ireland and Public Health England (1)
Key recommendations are that the high-risk criteria for future colorectal cancer (CRC) following polypectomy comprise EITHER:
- 2 or more premalignant polyps including at least one advanced colorectal polyp (defined as a serrated polyp of at least 10mm in size or containing any grade of dysplasia, or an adenoma of at least 10mm in size or containing high-grade dysplasia);
- OR
- 5 or more premalignant polyps
Notes:
- a study found that stool-based post-polypectomy surveillance strategies (microsimulation modelling using annual FIT-based surveillance with FOB-gold at a threshold ≥32 μg/g faeces) can be safe and cost-effective, with potential to reduce the number of colonoscopies by up to 41% (2)
