#83 Surgical treatment of duodenopancreatic neuroendocrine tumors (pNETs) in patients with multiple endocrine neoplasia type 1 (MEN 1): a Dutch consensus statement
Introduction: Duodenopancreatic neuroendocrine tumors (pNETs) in multiple endocrine neoplasia type 1 (MEN 1) are the most important cause of MEN 1-related death. Surgery is the only curative treatment, but controversy exists on the optimal strategy. Recent guidelines on pNETs have limited recommendations specific for MEN 1. Therefore, a Dutch multidisciplinary consensus meeting was organized.

#102 Presentation and outcome of pancreaticoduodenal tumors in Multiple Endocrine Neoplasia type 1 (MEN 1) syndrome
Introduction: Multiple endocrine neoplasia type 1 (MEN 1) is a rare autosomal dominant condition characterized by the development of parathyroid, pancreaticoduodenal endocrine and pituitaty tumors. Pancreaticduodenal endocrine tumors (PDETs) are a frequent manifestation of MEN 1, with a prevalence ranging from 30 to 75%, and represent a major cause of death in one-third of patients. There is continuing debate on their management, mainly on the optimal surgical strategy, due to their multicentricity and high recurrence rate.

#202 Extreme Obesity Due to Insulinoma Within Multiple Endocrine Neoplasia (MEN) 1 Syndrome
Introduction: Peak incidence of symptoms in women with multiple endocrine neoplasia (MEN) 1 is during the third decade of life. Insulinomas are present in 20% of patients and cause weight gain in 30% of patients.

#212 Reduced MEN1 Gene Expression in Pulmonary Carcinoids Is Associated With Metastatic Disease
Introduction: Lung carcinoids are neuroendocrine tumors that can be classified as typical (TC) or atypical (AC) carcinoids. Previously, MEN-1 mutations and associated LOH of 11q13 have been implied in tumorigenesis.

#348 Management of Multiple Endocrine Neoplasia Type 1 in Patients with Pancreatic Neuroendocrine Tumors
Introduction: Screening for MEN-1 is an integral part of examination of patients with pNETs because revelation of this hereditary pathology radically influences tactics of treatment.

#349 Gastrointestinal Stromal Tumor (GIST) Of The Esophagus In A Patient With MEN-1 And-Related Pancreatic Gastrinoma
Introduction: Both Multiple Endocrine Neoplasia type 1 (MEN-1; OMIM #613733)-related-gastrinomas and Gastrointestinal Stromal Tumors (GISTs; OMIM #606764) are rare neoplasms and their association has been rarely reported so far.

Introduction: Both multiple endocrine neoplasia type 1 (MEN1)-related-gastrinomas and Gastrointestinal Stromal Tumors (GISTs) are rare neoplasms, and their association has been rarely reported.

#930 Distinct Expression of Splicing Variants of the Human MEN1 (Multiple Endocrine Neoplasia Type 1) Gene in Various Pituitary Adenomas
Introduction: MEN1 is an autosomal-dominant tumor syndrome characterized by the occurrence of tumors in multiple endocrine tissues, including parathyroid, enteropancreatic neuroendocrine and anterior pituitary. The MEN1 gene consists of 10 exons transcribed into a 610 a.a. protein. It was reported that heterogeneity of human MEN1 gene transcripts related to variation in their 5’ UTR. Six distinct exsons1 (e1A-e1F) were isolated using RNA from thymus, pancreas and kidney.

#975 Electron Microscopy of Pancreatic Beta Cell Neuroendocrine Tumors (NETs) in Multiple Endocrine Neoplasia Type 1 (MEN1) Knockout Mice Reveal an Adenomatous Phenotype with Depletion of Insulin Granules and Increased Mitochondrial Content
Introduction: Insulinomas are β cell neuroendocrine tumors (NETs) that secrete insulin, and ~4% of insulinoma patients have multiple endocrine neoplasia type 1 (MEN1). One in ten MEN1 patients present with an insulinoma. Previous reports describe insulinomas as possibly having typical granules (46.4%) or atypical smaller granules (34.3%), both associated with adenomas, or agranular cells (14.3%) associated with carcinomas. MEN1 knockout (Men1+/-) mice develop pancreatic NETs that are mostly insulinomas, and their ultrastructural phenotype is unknown. We hypothesized that these may resemble the adenoma phenotype with atypical granules.
