#2929 Type III Gastric Neuroendocrine Neoplasms: Is Local Excision Sufficient in Selected Cases?

Introduction: As per ENETS Guidelines, patients with type III gastric neuroendocrine neoplasms (t-III g-NEN), need to undergo partial or total gastrectomy. Data for less-extensive resections are limited.

#2285 The Role of Magnetic Resonance Imaging and Endoscopic Ultrasound Imaging in the Diagnosis and Management of Pancreatic Neuroendocrine Tumors (pNET) in Patients with Multiple Endocrine Neoplasia Type 1 (MEN1)

Introduction: Pancreatic neuroendocrine tumors (pNETs) in patients with Multiple Endocrine Neoplasia Syndrome type 1 (MEN 1) are frequently multiple and occur with an incidence that varies from 30-80% in different series. Magnetic Resonance Imaging (MRI) and techniques such as endoscopic ultrasound (EUS) are useful tools for tumor localization, size assessment and follow-up.

#2284 The Association between Gastrin and Glucose Serum Concentration in Hypergastrinemic Patients with Gastric Neuroendocrine Tumors Type 1 and ECL-Cells Hyperplasia

Introduction: There is previous data demonstrating that elevated gastrin levels could exert some effect potentiating the glucose-induced insulin secretion.

#2191 Endocrine Paraneoplastic Syndromes in Patients with Neuroendocrine Neoplasms

Introduction: Endocrine paraneoplastic syndromes (ePNS) result from production of bioactive substances from tumours not related to their expected tissue of origin. Neuroendocrine neoplasms (NENs) have been associated with ectopic secretion of several hormones, but the prevalence of ePNS has only been described in a small number of studies.

#1935 Prevalence of Pancreatic Neuroendocrine Neoplasms with Serotonin Secretion

Introduction: Pancreatic neuroendocrine neoplasms (pNENs) are rare neoplasms and represent 1-2% of all pancreatic neoplasms. These tumors can secrete a variety of hormonally active substances producing distinct clinical symptoms, or can be clinically non-functioning. Pancreatic NENs that secrete serotonin are extremely rare, but their prevalence has not been explored adequately.
