Accuracy of radiographic assessment for the diagnosis of invasion depth in small invasive colorectal cancer.

摘要

Radiographic findings of 113 submucosally invasive colorectal cancers (CRCs) 10 mm. 47 CRCs had invaded the submucosa superficially while 66 CRCs had invaded deeply. The concordance rate in the assessment of radiology was 90.3% in smooth surface, 92.9% in central barium fleck, 90.3% in fold convergency and 79.6% in eccentric rigidity. Positive predictive value of central barium fleck for deep submucosal invasion was significantly higher in CRCs>10 mm than in those 10 mm. These findings suggest that barium radiography is a procedure which can give useful information in prediction of invasion depth in CRCs
