[Primary sarcomas of the gastrointestinal tract (author's transl)]

From 1952 to 1976 2203 malignant tumours of the gastrointestinal tract were seen at the Surgical Clinic of the M.H.L., 18 of them were sarcomas. There was a predominance of carcinomas of the stomach (Sa: Ca = 1:229) and of the colon (1:162), whereas sarcomas of the small intestine were found in a relation of 1:0,9. X-ray diagnosis of the gastric sarcomas is difficult, only those with endogastric growth can be recognized by gastroscopy. The postoperative prognosis of gastric sarcomas is better than that of gastric carcinomas. Sarcomas of the small intestine have a high mortality rate because of a high rate of ileus and perforation. Sarcomas of the colon - normally localized in the caecum or rectum - have a better prognosis, seldom stenosis can be seen.
