| Core Tip |
In this multicenter diagnostic study of 1176 colorectal lesions, pathologists’ accuracy and agreement for sessile serrated lesions (SSLs) and SSLs with dysplasia were evaluated. After clinical information was provided, the overall diagnostic accuracy improved from 66% to 72%; however, the diagnostic consistency of SSLs with dysplasia remained poor (κ = 0.114-0.132). Nuclear alterations (odds ratio = 10.45) and the cross-sectional crypt orientation (odds ratio = 5.27) were identified as factors that influenced diagnostic inconsistency. These results suggest that experience is insufficient to overcome the diagnostic challenges of SSLs. This finding reinforces the need for quantitative standards, algorithms for quality control of section orientation, and artificial intelligence-assisted curative devices to improve diagnostic precision. |
