[Adenomas and carcinomas of the small intestine in familial polyposis and Gardner syndrome--analysis of a literature survey].

Abstract

An analysis of 70 case records from the literature of patients with familial polyposis or Gardner syndrome and adenomas or carcinomas of the small bowel demonstrated that there is no difference between the neoplasms of the small bowel in familial polyposis or in Gardner syndrome. Between the adenomas and the carcinomas of the small bowel it was possible to show, that there exists a similar close relation as in the large intestine. In some carcinomas of the small bowel rests of adenomas can be observed. The peak incidence of small bowel adenomas is more than a decade earlier than that of carcinomas. The distribution of adenomas in the small bowel is quite similar to that of carcinomas. Therefore it can be supposed, that the significance of familial polyposis coli and Gardner syndrome for the importance of an adenoma-carcinoma-sequence in the large bowel is also existing in the small bowel.
