[Primitive adenocarcinoma of the duodenum. Description of two clinical cases]. / Adenocarcinoma primitivo del duodeno. Descrizione di due casi clinici.

Two cases of a primitive adenocarcinoma of the duodenum are presented. Both cancers were localized near the papilla. Duodenocephalopancreatectomy was the surgical treatment for each patient. One patient died of myocardial infarction eight months after surgery, without any sign of recurrence of the cancer; the other is in good health three months after surgery. The rarity of such a tumor is underlined: in 44 papers published in various journals from 1971 to 1993, 88 cases of primitive adenocarcinoma of the duodenum were examined; the average number of cases per author was two. Between 1980 and 1993, an Italian multicenter study carried out in 36 hospital and university centers, showed only 89 cases of primitive duodenal adenocarcinoma.
