Update in Surveillance Recommendations in Individuals With Conventional Adenomas
- 41 Downloads
Purpose of review
Conventional adenomas, which are precursors to almost 70% of colorectal carcinomas, are found in more than one-third of screening colonoscopies. Surveillance recommendations, based on adenoma size, histology, and number, have evolved over the years and are currently reflective of index adenoma categorization as either low-risk (LRA) or high-risk (HRA). In this review, recent guideline recommendations as well as primary data that have helped to shape these recommendations are presented.
Recent data have demonstrated that individuals with HRA on index exams may be at increased risk for CRC while those with LRA may have a minimal long-term risk for CRC, similar to those adults with normal index exams. Furthermore, the quality of the index exams is important for minimizing CRC risk.
While individuals with HRA may require close surveillance intervals of 3 years, those with LRA or normal exams may need longer such as 10-year follow-up.

Individuals with low-risk adenomas had risk similar to that of those with no adenomas.CrossRefGoogle Scholar

Gastroenterology. 2018;154:117–127 e2 This analysis of data from the New Hampshire Colonoscopy Registry showed that the presence of index serrated polyps, especially sessile serrated polyps (SSP), can increase the risk for metachronous high-risk conventional adenomas (HRA), even greater than that for those with HRA alone. This paper also presented data that showed that large (> 1 cm) serrated polyps or SSPs predict metachronous large SPs but not HRA. CrossRefGoogle Scholar

J Clin Gastroenterol. 2018;52:628–34 This retrospective analysis of data from a chemoprevention trial demonstrated that a new risk stratification approach to surveillance, which involved adding adenoma size, performed as well as the conventional paradigm.
