#2866 Extrahepatic 68Ga-DOTATATE-Avid Tumor Volume and Serum Chromogranin A Predict Short-Term Outcome of 177Lu-DOTATATE in Late-Stage Metastatic Gastroenteropancreatic Neuroendocrine Tumors
Introduction: 177Lu-DOTATATE is an effective therapy for somatostatin receptor-positive neuroendocrine tumors (NETs). Often enough 177Lu-DOTATATE is used as the last treatment resort in advanced NET.

#2897 Comparison of 68Ga-DOTATATE PET/CT for Assessment of Response to Peptide Receptor Radionuclide Therapy after 2 and 4 Cycles of 177Lu-DOTATATE: Preliminary Single Academic Center Experience
Introduction: Peptide receptor radionuclide therapy (PRRT) usually leads to stable rather than decreased lesion size in neuroendocrine tumors (NETs), therefore RECIST criteria are not used to assess early response to treatment.

#2798 Risk of Pre-Operative Understaging of Duodenal Neuroendocrine Tumors at Conventional Imaging: When Surgery Becomes the First Choice
Introduction: Duodenal neuroendocrine neoplasms (dNENs) are heterogeneous tumors that can exhibit aggressive behavior, with loco-regional nodes and distant metastases. Pre-treatment staging is the basis for planning either surgical or endoscopic treatment.

#2890 Evaluation of Toxicity in Peptide Receptor Radionuclide Therapy (PRRT) for Neuroendocrine Tumors (NET)
Introduction: Peptide receptor radionuclide therapy (PRRT) is an encouraging systemic treatment for neuroendocrine tumors (NET). PRRT is generally safe and possesses little side effects but little is known about liver toxicity.

#2909 Serotonin-Secreting NeuroEndocrine Neoplasms of the Pancreas: Which Are the Primary Pancreatic Carcinoids?
Introduction: Serotonin-secreting pancreatic neuroendocrine neoplasms (5-HT-secreting pNENs) are very rare. They are characterised by high urinary 5-hydroxyindole-acetic acid (5-HIAA) levels (or high serum 5-HT levels).

#2931 One-Stage Middle-Preserving Pancreatectomy: Indications and Outcomes
Introduction: Parenchyma-sparing surgical techniques are used in pancreatic surgery to preserve organ function. Middle-preserving pancreatectomy (MPP) may be an alternative to total pancreatectomy (TP) in benign/borderline disease that does not affect pancreatic body.

#22 A Case Illustrative of Phenotypic Heterogeneity and Challenges in the Management of Paraganglioma
Introduction: Paragangliomas (PGLs) are extra-adrenal, usually benign, highly vascularized tumors that originate from neural-crest-derived chromaffin cells. These tumors are subdivided as either sympathetic or parasympathetic, depending on their location and catecholamine production. Sympathetic PGLs are situated along the abdominal sympathetic trunk and usually produce catecholamines, whereas parasympathetic PGLs are located in the head and neck, and these usually do not produce catecholamines. PGLs may present as sporadic or inherited tumor syndrome, including MEN 2, with RET germline mutations, von Hippel-Lindau (VHL) disease due to germline mutations in VHL gene, and pheochromocytoma-PGL syndrome. The latter is frequently a hereditary condition and is caused by germline mutations in the SDHB, SDHC, or SDHC genes. Patients with familial PGLs may present at a younger age, often as multifocal tumors, with an increased risk of recurrence and a higher frequency of malignancy in those with SDHB mutations. SDH mutations induce angiogenesis and tumorogenesis through the inhibition of hypoxia-inducible factors (HIF)-propyl hyroxylase. A younger age at onset, malignancy, and a positive family history are clinical parameters of high specificity, but low sensitivity for diagnosis. Genetic analysis for mutations in SDH genes for the patient and family members, and surveillance for the affected patient and family members, are necessary where there are no clear clinical or family indicators for the syndrome. We present a case of a large abdominal malignant PGL in a 20-year-old pt. that went on without clinical detection for at least three years.

#43 Relationship between neuroendocrine tumor-related symptoms and RAND-36 health-related quality of life scores

#62 Genome-wide DNA methylation profiling of pancreatic neuroendocrine tumors identifies distinct methylation profiles and differentially methylated gene promoter regions associated with low, medium and high grade tumors
Introduction: Integration of genetics and epigenetics has emerged as a powerful approach to studying cellular differentiation (Mikkelsen et al, 2009) and tumorigenesis (Shen et al, 2007). The study of DNA methylation is of particular importance in cancer, as causal involvement has been demonstrated and it is the most stable of all epigenetic modifications, making it a desirable marker for both early detection and treatment of tumors. Hypermethylation of CpG sites in gene promoter regions leads to decreased gene expression; if such a gene is a tumor suppressor, this leads to carcinogenesis. To date, there have been no studies of genome-wide DNA methylation profiling of NETs. This study sets out to determine the DNA methylation profiles of low, intermediate and high grade pancreatic NET liver metastases with the intention of identifying dysregulated biological pathways in the development of these tumors. A protocol for the analysis formalin-fixed paraffin embedded tissue (FFPE) has also been developed in order to study these tumors in significant numbers following this pilot study.
