#3048 Somatostatin Analogs or Active Surveillance in Sporadic Non-Functioning Pancreatic Neuroendocrine Tumors
Introduction: Non-functioning (NF), sporadic pancreatic neuroendocrine tumors (pNETs) have usually an indolent behavior, but sometimes show an unpredictable aggressiveness. Surgery is the first-choice for localized tumors >2 cm. Unresectable or metastatic lesions expressing somatostatin receptors (SSTRs) are treated with Somatostatin analogs (SSAs). No evidence of SSAs efficacy exists in tumors ≤2 cm, for which active surveillance has been proposed.

#3014 The Number of Positive Nodes Accurately Predicts Recurrence after Distal Pancreatectomy for Nonfunctioning Neuroendocrine Neoplasms
Introduction: The most appropriate staging system of metastatic lymph nodes (N) for resected pancreatic neuroendocrine tumors (PanNETs) remains unclear, especially regarding those resected by distal pancreatectomy (DP).

#2833 Surgical Correction of Carcinoid Heart Disease Improves Liver Function and 5-Hydroxyindoleacetic Acid Levels
Introduction: Neuroendocrine tumours of the gastrointestinal tract cause carcinoid syndrome and carcinoid heart disease. These tumours secrete serotonin, which can bind to heart valves and cause fibrosis and valve incompetence. Most cases involve the tricuspid valve +/- pulmonary valve. Medical management comprises diuretics for fluid overload and somatostatin analogues to reduce circulating serotonin. Definitive treatment is heart-valve replacement surgery which improves exercise tolerance but has high perioperative mortality. We have previously reported that valve-replacement surgery can reduce 5-hydroxyindoleacetic acid (5-HIAA) levels, reflecting a decline in hormone activity.

#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.

#2972 Characteristics and Management of Paragangliomas, 10 Years Experience
Introduction: Paraganglioma (PG) is a rare extra-adrenal neuroendocrine tumor, with common sites of presentation being abdomen, and head and neck region. The majority of PGs appear to be sporadic. However, almost half of cases are associated with an inherited syndrome. The highest malignancy rates are seen in paragangliomas (PGs) associated with SDHB mutations, which are usually abdominal and secretory.

#3047 Functional Consequence of β-Arrestin 1 Gene Knock-Out in Pancreatic Neuroendocrine Tumor Cell Line BON-1
Introduction: An important limiting factor influencing treatment efficacy of neuroendocrine tumors (NETs) with somatostatin analogs (SSA) is the availability of somatostatin receptors (SSTR) on NETs. While downregulation or altered pattern of SSTR expression are important considerations, receptor internalization/desensitization by β-arrestins may be a crucial contributing factor. Interestingly, our previous study showed a preferential higher expression of β-arrestin 1 (ARRB1), in gastroenteropancreatic NETS (GEP-NETs) compared to pituitary adenomas.
