#2691 Somatostatin Analogs in Patients with Zollinger Ellison Syndrome (ZES): An Observational Study
Introduction: Zollinger Ellison syndrome (ZES) is a rare syndrome caused by gastrin hypersecretion from a primary neuroendocrine tumor (NET), usually located within the duodenum or into the pancreas. Gastrinomas have two important treatment goal: the control of the gastrin-excess state and the control of tumor growth.

#2955 Development of an EORTC Quality of Life Questionnaire for Patients with Pancreatic Neuroendocrine Tumours: Phases 1-3
Introduction: Measuring quality of life (QoL) in Pancreatic Neuroendocrine Tumours (pNET) involves assessing issues from symptoms, disease and treatment. The validated gastrointestinal NETs module (EORTC QLQ-GINET21) is used with EORTC QLQ-C30 but there are concerns it inadequately measures QoL in pNET.

#17 Diagnostic efficacy of the secretin stimulation test for the Zollinger-Ellison syndrome: an intra-individual comparison using different dosages in patients and controls
Introduction: The diagnosis of Zollinger-Ellison syndrome is suspected in patients with symptoms of gastric acid hypersecretion, i.e., peptic ulcer disease, malabsorption or diarrhea, or with elevated fasting serum gastrin levels. However, symptoms can be masked by the use of proton pump inhibitors and fasting serum gastrin values are not always conclusive. Therefore, the secretin stimulation test is advocated as the principal diagnostic tool to identify the Zollinger-Ellison syndrome.

#21 Peptide Receptor Radioligand Therapy (PRRT) is an Effective Treatment for the Long-Term Stabilization of Malignant Gastrinomas
Introduction: Gastrinomas represent a rare group of neuroendocrine tumors usually located in the duodenum or pancreas. They secrete gastrin, which is responsible for the clinical picture of severe acid-related peptic disease and diarrhea, known as the Zollinger-Ellison syndrome (ZES). While symptomatic control may be achieved with proton-pump inhibitors (PPIs) and somatostatin analogues (SSAs) treatment, little data is known regarding the possible anti-tumor effect of the peptide receptor radioligand therapy (PRRT) in gastrinoma patients.

#61 Multiple tumors in patients with pancreatic neuroendocrine tumours: morphological and immunohistochemical characteristics
Introduction: Pancreatic islet cell tumors occur in 80% of patients with MEN 1. Tumors are often multicentric. They often produce multiple peptides and biogenic amines.

#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.

#106 Gastroenteropancreatic neuroendocrine tumors: single institution clinicopathological study
Introduction: Neuroendocrine cells are widely distributed throughout the body, and neoplasms from these dispersed cells can arise at many sites. They are distinguished into two broad categories: 1) Tumors identified as small cell lung carcinomas with biology and natural history of a high-grade malignancy and characteristics of small cell undifferentiated or anaplastic appearance by light microscopy. The WHO categorizes these tumors as poorly-differentiated neuroendocrine carcinomas; 2) Well-defined neuroendocrine tumors (NETs) with variable, but most lyindolent biologic behavior and characteristic well-differentiated histologic features. The majority arise in the gastrointestinal tract and collectively they are referred as gastroenteropancreatic neuroendocrine tumors (GEP/NETs). They include carcinoid tumors, pancreatic islet cell tumors (gastrinoma, insulinoma, glucagonoma, VIPoma, somatostatinoma), paragangliomas, pheochromocytomas, and medullary thyroid carcinomas. The WHO classifies the GEP/NETs as well-differentiated NETs (carcinoid tumors) if they are noninvasive and have benign behavior or uncertain malignant potential. In contrast, GEP/NETs with characteristics of low-grade malignancy with invasion of the muscularis propria or beyond, or metastases, are characterized as well-differentiated neuroendocrine carcinomas (malignant carcinoids). Pancreatic islet cell tumors, whether functioning or not, are classified as well-differentiated NETs or well-differentiated neuroendocrine carcinomas, due to the (depending on) histologic characteristics. The WHO classification for gastroenteropancreatic NETs based on stage (ie size and presence of metastases) and grade (mitotic rate, perineural and lymphovascular invasion, Ki-67 proliferative index) categorizes them as well-differentiated NETs, e.g., carcinoid tumors, or as well-differentiated neuroendocrine carcinomas.
