Clinical takeawayConsider extending surveillance intervals beyond 6 months for hot EMR of LNPCPs ≥20mm when all four low-risk features are present (no prior resection, margin ablation done, no villous histology, no ICV involvement), pending prospective validation.
What it foundA 4-factor model (prior resection, no margin ablation, villous histology, ICV involvement) stratified recurrence risk after hot EMR: low-risk polyps had 2.2% recurrence at 6 months compared to 10.6% in high-risk polyps, 5.4% vs 23.1% at 12 months, and 9.7% vs 28.1% at 18 months.
ContextChallenges current uniform 6-month surveillance by identifying a low-risk subgroup with <10% recurrence at 18 months, though prospective validation is needed before guideline changes.
No standard claimed for this paper

Every paper is compared to the standard governing its question. This one is not: either no standard in the corpus matches it, or the comparison did not hold up on review and was withdrawn rather than published unverified. Both are logged.
