These distinct features in tumor growth, secretory capacity and localisation are consequently reflected in the wide variation in clinical presentation of different NETs. Moreover, a number of NETs may be found incidentally when patients undergo surgery for unrelated reasons or may be an unexpected finding in the histopathological specimen as with(More)

age peak in the 6th and 7th decades of life [1] . The frequency of multicentricity lies between 26 and 30% [3, 4] and 15–29% of tumors are associated with other non-carcinoid malignancies [5–7] . The WHO classification subdivides jejunal-ileal tumors, similar to other gastroen teropancreatic endocrine tumors, into three general categories [8] : (1)(More)

PURPOSE Six pheochromocytoma susceptibility genes causing distinct syndromes have been identified; approximately one of three of all pheochromocytoma patients carry a predisposing germline mutation. When four major genes (VHL, RET, SDHB, SDHD) are analyzed in a clinical laboratory, costs are approximately $3,400 per patient. The aim of the study is to(More)
Somatostatin-producing neuroendocrine tumors (SOM-NETs) of the duodenum and pancreas appear to be heterogeneous. To determine their clinicopathological profiles, respective data were analyzed on a series of 82 duodenal and 541 pancreatic NETs. In addition, the clinical records of 821 patients with duodenal or pancreatic NETs were reviewed for evidence of a(More)
Orexin-A (OXA) regulates food intake and energy homeostasis. It increases insulin secretion in vivo and in vitro, although controversial effects of OXA on plasma glucagon are reported. We characterized the effects of OXA on glucagon secretion and identify intracellular target molecules in glucagon-producing cells. Glucagon secretion from in situ perfused(More)
