Localisation of neuroendocrine tumours of the upper gastrointestinal tract.
In order to localise neuroendocrine tumours of the foregut type (that is, of the stomach, duodenum, and pancreas), 18 patients were studied prospectively by endoscopic ultrasonography, computed tomography, transabdominal ultrasonography, magnetic resonance imaging, and somatostatin receptor scintigraphy. These 18 patients had a total of 25 primary tumour lesions which were verified histological...
متن کاملNeuroendocrine gastrointestinal tumours.
Neuroendocrine gut and pancreatic tumours have provided a diagnostic and therapeutic challenge over the years. These rather slowly growing neoplasms have been assigned a good prognosis but when liver metastases are present the prognosis is not better than that of most other malignant tumours. Despite the development of improved diagnostic procedures many patients are still referred at a stage o...
متن کاملNeuroendocrine Tumors of the Gastrointestinal Tract.
Gastrointestinal neuroendocrine tumours are classified as functioning or non-functioning according to the presence or absence of a clinically evident hypersecretion syndrome. In foregut tumours the presence of autonomous hormone secretion and the respective hypersecretion syndrome indicate functionality. Abdominal ultrasound (US), computed tomography (CT), magnetic resonance tomography (MRT) an...
متن کاملNeuroendocrine neoplasms of the gastrointestinal tract.
BACKGROUND Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) are complex tumors whose incidence is rising and whose treatment requires precise classification and risk stratification. METHOD Selective review of the relevant literature, including recently published guidelines. RESULTS GEP-NENs are initially classified by their degree of histological differentiation and their graded c...
متن کاملAmyloid precursor-like protein 1 is differentially upregulated in neuroendocrine tumours of the gastrointestinal tract.
We have examined the global gene expression profile of small intestinal carcinoids by microarray analysis. High expression of a number of genes was found including amyloid precursor-like protein 1 (APLP1). Quantitative real-time PCR and western blot analysis demonstrated higher expression of APLP1 in carcinoid metastases relative to primary tumours indicating a role of APLP1 in tumour dissemina...
