Adenocarcinoma of the small bowel. Clinical features, similarity to regional enteritis, and analysis of 338 documented cases

Abstract

A case of ileal adenocarcinoma is presented and the clinical features of adenocarcinoma of the small bowel are discussed. Special attention is paid to the differentiation of this tumor from Crohn's disease. Analysis of Connecticut Tumor Registry data on 338 cases of small intestinal adenocarcinoma occurring between 1935 and 1978 reveals a predilection for the elderly but no sex predominance (male/female = 0.965). Two hundred fifty-four patients were followed for at least 5 yr, and the overall (1935-1978) 5-yr survival rate was 17.3%. No improvement in survival has taken place in Connecticut over the past 40 yr.
