Two or More Advanced Lesions or High-Grade Dysplasia Predict Shorter Surveillance Intervals Than Current Recommendation

Since 2012, the Multi-Society Task Force on Colorectal Cancer has recommended that patients with an advanced colorectal lesion (adenoma or sessile serrated lesion [SSL] ≥10 mm, adenoma with high-grade dysplasia or villous elements, SSL with dysplasia, or traditional serrated adenoma) undergo colonoscopy in 3 years.
In a retrospective analysis of 1120 patients with advanced lesions at a single U.S. center, 18.5% of patients received a surveillance recommendation other than 3 years. Short intervals were associated with high-grade dysplasia (odds ratio [OR], 4.33) or at least 2 advanced lesions (OR, 2.28). Longer intervals were more common than too-short intervals and were associated with flat polyps, with the largest lesion 12 mm or larger in diameter.
