Recent studies have added complexity to our understanding of postpolypectomy surveillance risk, such as the risk of metachronous advanced neoplasia is higher with 6- to 9-mm baseline adenomas than 1- to 5-mm baseline adenomas. A common scenario in clinical practice is for patients to have both small (<1 cm) conventional adenomas and concurrent serrated polyps (SPs; defined as either small sessile serrated lesions [SSLs] or small hyperplastic polyps [HPs]).<\/p>\n\n\n\n
This study looked at the risk of metachronous advanced neoplasia, defined as either advanced conventional adenomas or advanced serrated lesions (serrated polyps [SPs] \u226510 mm or with cytological dysplasia) at follow-up.<\/p>\n\n\n\n
In a two-center U.S. study, 1389 patients had either isolated small tubular adenomas (TAs; 82% of the group) or TAs plus SPs (18% of the group: 15.3% had an HP as their SP, and 2.8% had an SSL).<\/p>\n\n\n\n
The risk of any metachronous advanced neoplasia was 5.2% in the group with isolated, small TAs, 9% in those with TAs plus small HPs, and 12.8% in patients with TAs plus small SSLs.<\/p>\n\n\n\n
The additional metachronous advanced neoplasia created by the group with both TAs and SPs was accounted for by more advanced SPs at follow-up. There were no metachronous cancers at follow-up.<\/p>\n","protected":false},"excerpt":{"rendered":"
