[Primary malignant tumours of the small intestine (author's transl)].

In the years between 1936 and 1973 19 patients with malignant tumours of the small intestine were admitted to the 2nd Department of Surgery, University of Vienna. Analogous to the findings of large-scale investigations adenocarcinomas (7 cases) preponderate in the upper small intestine in our case material, while lymphosarcomas and carcinoids mainly occur in the ileum. A radical surgical procedure was possible in 11 cases. The adenocarcinomas have the most unfavourable prognosis, whilst survival times of up to 10 years were found with lymphosarcomas and carcinoid tumours.
