On the postoperative prognosis in ulcer-carcinoma of the stomach.

From the findings that a cancer focus in the mucous membrane at the ulcer margin may not infrequently infiltrate the deeper part of the ulcer base though its area is smaller than 2 cm . in maximum width, and that the base of callous ulcer is made up of callous omentum tissue, Majima1) h as concluded, in his paper on the process of development of ulcer-carci noma, that carcinomatous infiltration of the ulcer base is indicative of an early stage of peritoneal carcinomatosis, and that there are found not a few cases in which only poor prognosis is to be given in spite of the small size of the lesion. We have made an investigation of late results of gastrectomy in cases in our clinic, and comparison has been made between these results and histopathologic findings with the resected specimens, with the results to be reported in the present communication.
