 Transfiguration of operated early gastric cancer was studied from the standpoint of radiologic examination and diagnosis of the stomach. It was revealed that total number of operated early gastric cancer has markedly increased. Especially, the number of depressed early gastric cancer obviously increased in contrast to decrease in the number of polypoid early cancer operated. Depressed early cancer on the anterior wall, upper portion and greater curvature also increased in number. The number of minute cancer and cancer in the fundic gland mucosa also has increased in the recent years. It is considered that such an increasing tendency in the operated number of early gastric cancer has been brought about by the progress of the radiologic examination.

 On the contrary, the operated number of Type Ⅱb lesion has still remained unchanged, probably due to the fact that it is not visualized under fluoroscopy even with image intensifier of high resolution quality. In addition, a definite line should be drawn as to the equivocal definition of Ⅱb-like or Ⅱb-simulating lesion.

 It deserves mentioning that difference in the macroscopic and radiologic characteristics between differentiated and undifferentiated type of gastric carcinoma has been clarified, based on intensive comparative studies on radiologic and pathologic findings. According to Nakamura, early diagnosis of linitis plastica type carcinoma can be made by discovering a Ⅱc lesion in the fundic gland area, without converging folds and measuring less than 2 cm in diameter. Theoretically, a Ⅱc lesion like this may easily be diagnosed in the radiologic examination because its depression is rather deep with sharply defined limits.

 In Japan, from now on, the number of cases of undifferentiated type of carcinoma is anticipated to increase compared to that of differentiated type of carcinoma. This tendency, however, is not shown yet in the figure drawn out from our data.

 Incidence and reported cases of narrowing of the pyloric lumen due to depressed early cancer are very few, and scarcely discussed in the literature.

 In these recent years we have been putting our greatest efforts on improving radiologic equipments. Acutually the improved radiologic equipments have drastically raised the number of detected cases of early gastric cancer. What in urgent need are to improve radiologic equipments based on rational radiologic examination theory and to develop human resources.
