  • Abstract
  • Look Inside

 In accordance with recent progress in the diagnostic technics for early gastric cancer, more and more minute lesions are now accurately diagnosecl. Concomitantly, those benign lesions are now more freuently encountered which closely resemble early gastric cancer by their gross as well as x-ray and endoscopy findings. Sometimes their discrimination is fairly difficult.

 In our own cases as well, we have been confronted with many cases hardly distinguishable from early gastric cancer not only in their x-ray and endoscopy pictures but also in their macroscopic findings.

 The incidence of lesions simulating Ⅱc and Ⅱc+Ⅲ type early gastric cancer was highest in our series, followed by those resembling Ⅱa and Ⅱa+Ⅱc types. Of all types of early gastric cancer, the one showing highest incidence has its most frequent counterpart in lesions simulating it.

 Roentgenologically, discrimination between depressed type early gastric cancer and its simulating lesions lies in the faithful visualization of zonal gastritis around ulcer or ulcer scar as well as in the accurate interpretation of findings thus obtained.

Protruding variety of early gastric cancer must be strictly evaluated on the basis of minute scrutiny of mucosal surface, taking two factors, the shape and size of tumor, into consideration. Afterall, compression and double contrast methods are most fruitful. Needless to say, as these x-ray diagnostic methods have their limitations, endoscopy and biopsy must be fully utilized as well. The latter in particular plays a decisive role in the discrimination between cancer and non-cancerous lesion. Nevertheless, the value of x-ray diagnosis for early gastric cancer is not lessened at all. It is very effective in picking up abnormal findings, or in determining both the accurate sphere of a lesion after it has been confirmed as cancer and the extent of the area of the stomach to be resected. No other examination method has such an important role.
