 We classified 143 lesions from 139 cases of superficial squamous cell carcinoma of the esophagus that had been radiographically examined in detail in our department into the protruding type(44 lesions)and flat-and depressed-types(99 cases), and assessed the ability of frontal radiographs to visualize small squamous cell carcinomas and their properties. The results showed that they were capable of visualizing 6 lesions out of 6(100%)of the protruding type of M1-2 cancers that measured 11 mm or more in diameter and 4 lesions out of 5(80%)of the small lesions measuring 10 mm or less in diameter. The visualization rate for flat-and depressed-type M1-2 cancers was 8 lesions out of 11(73%)for lesions measuring 31 mm or more in diameter and decreased as the tumor diameter became smaller. Ability to visualize small lesions measuring 10 mm or less in diameter was 4 lesions out of 8(50%), which was poorer than for the protruding type. The non-visualizing clinico-pathological factor of early esophageal cancer was M1 cancer measuring 10mm or less in diameter and was non-total layer replacement type M1 cancers of any tumor size. By contrast, the radiographs were capable of visualizing all 4 of the depressed-type M3 or deeper cancers 10 mm or less in diameter. Dense barium fleck with a clearly demarcated border and a marginal elevation were observed, and they were useful findings for diagnosing depth of invasion. Radiography examinations appeared to be useful for diagnosing the presence and depth of invasion of small depressed-type cancers with a risk of metastasis.
