#3020 Outcomes Following Surgical Management of Pulmonary Carcinoids – A Tertiary Center Experience

Introduction: Pulmonary carcinoids are a rare type of malignant lung tumour. Surgery forms the mainstay of management when operable. However, there is paucity of data on conservative management and effective follow-up strategies.

#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.

#121 Serotonin synthesis inhibitors: a novel approach for managing gastrointestinal symptoms in carcinoid syndrome

Introduction: Carcinoid syndrome (CS) occurs when metastatic carcinoid tumors secrete large amounts of serotonin (5-HT) and other bioactive substances into systemic circulation, causing a variety of symptoms, including GI symptoms such as profound diarrhea. Reduction in 5-HT production by the tumor would be expected to improve symptoms in patients with CS.
