 In order to clarify radiological features of extent and depth of invasion in cases of early esophageal cancers, esophagograms of fifty eight type 0-Ⅱc (slightly depressed) lesions were analyzed. Radiological findings which represented each depth of invasion (esophageal cancer confined to the epithelium: m1, the lamina propria mucosae: m2, reaching to the muscularis mucosae: m3 and those invading slightly into the submucosa: sm1) were studied.

 In cases with m1 (20 lesions) and m2a (those with cancer infiltration slightly into the lamina propria mucosae: 14 lesions) cancers, 88% of all lesions showed minimal depression with smooth surface or slight undulation. In cases with mucosal cancer infiltrating into the deeper half of the lamina propria mucosae (m2b: nine lesions), 78% of all lesions showed mild depression with well defined granules. In cases with m3 (eight lesions) and sm1 (seven lesions) cancers, either large granules in a mild depression or slight elevation in a moderate depression was noted. Abnormalities of longitudinal mucosal folds suggested extent of cancer lesions: irregularity of width of folds was suggestive of extent of m1 cancer. On the other hand, tall and wide mucosal folds indicated cancer invasion into the muscularis mucosae or ever deeper. Accuracy rate of differentiation of m1 and m2 cancers from m3 and sm1 was 91%. Histological features of lesions with failed estimation of depth of invasion were m3 cancers narrowly reaching to the muscularis mucosae and sm1 cancers with infiltration replacing the epithelium of the ducts of esophageal glands.
