[Ulcerocancer of the stomach (author's transl)].

46 patients were operated upon for an ulcerocancer of the stomach. In detail the differential diagnosis and the possibilities for preoperatively establishing an exact diagnosis are described. The good results after resection of the tumor (5-year-survival rates are for early cancer 100% and for the other tumors 67.7%) demonstrate, that usually for the ulcerocancer a total gastrectomy is unnecessary. Depending on the localisation of the tumor a proximal or distal resection of the stomach is sufficient. The results indicate that tumors, in which the ulcer floor shows a partial infiltration of carcinomatous cells, are not to be called as ulcerocancer. It is suggested to speak of these cases of "primary" carcinoma of the stomach.
