Management di un paziente portatore di neoplasia neuroendocrina non funzionante del tratto gastro-entero-pancreatico (GEP)

The Authors examine the feasibility of diagnosing non-functioning gastroentero-pancreatic neuroendocrine tumours preoperatively or intraoperatively, with particular reference to laboratory examinations and octreoscan scintigraphy, which are capable of conditioning the surgical treatment and subsequent follow-up. Of the 4 cases reported here: three presented multiple intestinal localizations, and in only one case the origin of the primitive carcinoma was undefined. The suspicion of a non-functioning neuroendocrine tumour must be considered when yellowish or ochre-coloured intestinal lesions are found intraoperatively. Determination of specific markers and octreoscan scintigraphy must be performed without awaiting histological confirmation. Surgery plays a fundamental role in the debulking of these carcinomas. However, medical therapy with the aid of specific laboratory examinations and octreoscan scintigraphy may improve the long-term survival
