  • Abstract
  • Look Inside

 A study has been made of gastric cancer cases we were able to follow up retrospectively regarding their clinical courses, together with cases of early cancer of the stomach that could possibly be anticipated of their further developmental process. All cases have been selected from those that displayed no fusion of the muscularis mucosae and the proper muscle layer. How they develop is as yet not fully ascertained, but from the clinical standpoint we assume that: Some of them may evolve from the initial change in colcr of the mucosal surface (Ⅱb-like lesion. developing into the stage of either Ⅱa-life Ⅱb or Ⅱc-like Ⅱb, finally showing a pattern of Ⅱc+Ⅱa as was illustrated in the final endoscopic of Case 5. Some of them may present findings similar to those in Case 2, while others, first showing a picture of Ⅱc+Ⅱa and on the whole looking like Ⅱa, may finally display such endoscopic pictures as were seen in Case 1.

 The presence or absence of cancer destruction, vascular invasion in the course of cancer development or some other biologic factors may be responsible for the speed of depth invasion of cancer and of its development.
