  • Abstract
  • Look Inside

 Macroscopic study of the natural course in respective types of early gastric cancer and the depth of its infiltration into deeper layers are studied in this paper, laying stress on 184 cases of early gastric cancer encountered in the authors' hospital for the past three years and ahalf. Of 18 such cases followed up for more than six months, four are of protruding type and they invariably exhibit enlargement of protrusion, whereas cases of the same type observed less than six months show slight, if any, changes in the aspect of protuberance. As for the depressed type of early gastric cancer,14 cases have been followed up for more than six months, and a few of them are seen to remain for two or three years in the initial state of early gastric cancer. Ulcer lesion associated with it, however, has usually been observed to occur within a short space of several months after the inception of follow-up.

 As regards the relation between the size of early cancer and the depth of its invasion, smaller lesions less than 2cm in diameter belong mostly to intramucosal cancer with or without localized submucosal involvement, so that generally they can be placed in the category of intramucosal carcinoma. It is nevertheless noteworthy that depressed type early gastric cancer tends to develop submucosal penetration as compared with that of protruding type.

 Pertaining to the depth of early cancer invasion, studies are further made of early gastric cancers mistaken prior to operation for advanced ones, as well as of veritable advanced cancers erroneously diagnosed preoperatively as early carcinomas.
