[Malignant tumors of the small intestine. Comments concerning 21 observed cases].

Patients affected by malignant tumors of the small intestine observed by the Department of Clinical and Pathological Surgery at the University of Florence were studied from 1964 to 1989. The most important aspects of the disease were studied, on the one hand emphasising its low incidence and on the other the poor prognosis which accompanies it. Greater attention should be focused on these lesions in order to enable an early diagnosis to be made since this currently represents the sole possibility for carrying out an efficacious therapy.
