#2992 The PanNENomics Project: A Call for an International Collaborative Effort Built on the Success of the LungNENomics Project
Introduction: Neuroendocrine tumors are rare understudied diseases at the molecular level, especially those occurring in sites outside the lung and the gastrointestinal track. This lack of knowledge has strong implications for the clinical management of these diseases (Rindi et al. Mad Pathol 2018).

#3073 The Role of Rb as a Prognostic Factor in Grade 3 Poorly Differentiated Neuroendocrine Carcinoma (G3NEC) Treated by First Line Platinum-Etoposide Combination, a Retrospective Study
Introduction: G3NEC are heterogeneous and aggressive diseases which can arise in different organs. Platinum-etoposide combination is used as first line treatment whatever the primary. Rb has been suggested to be a predictive/prognostic factor.

#2737 Identification of a Novel MAFA Missense Mutation Causing Familial Insulinomatosis
Introduction: Insulinomatosis is a rare pancreatic disease characterized by an adult-onset condition of recurrent hyperinsulinemic hypoglycemia caused by multiple insulin-secreting neuroendocrine tumors.

#2812 SILVELUL Project: Development of an New Potential Predictive Immunohistochemical Score (SPI) in Patients (pts) with Pancreatic Neuroendocrine Tumors (PanNET) Treated with CAPTEM or Everolimus
Introduction: Previously our group showed the potential use of a score based on MGMT, NDRG-1 and PHLDA-3 immunohistochemistry (IHC) expression as predictor of outcome in operated PanNET (Viúdez et al. Oncotarget 2016).

#2961 Our Experience Using a New Scoring System to Detect Disease Recurrence after Curative Surgical Resection of Well-Differentiated Pancreatic Neuroendocrine Tumors
Introduction: For patients with nonfunctioning pNET  ≥20 mm in size without distant metastasis, complete surgical resection is recommended as the primary curative strategy. Effective follow‐up programs are designed to detect recurrence at an early stage, given that treatment of limited disease has the most favorable outcome. However, data on post‐curative surgical recurrence remains limited, making it challenging to determine the best follow‐up strategy and to detect the best treatment options as an adjuvant therapy for selected patients.

#2977 Predicting Survival in Patients with a Neuroendocrine Tumor of the Small Intestine (SI-NET)
Introduction: SI-NET comprise the largest group of neuroendocrine tumors. Because of their heterogeneity, predicting survival has proven challenging. A nomogram (NG) to assess SI-NET disease specific survival (DSS) has been developed in 2010 by Modlin, et al. based on analysis of retrospective data from the Surveillance, Epidemiology and End Results (SEER) database.

#3046 Incidence of Neuroendocrine Neoplasms Reported in England 2015-2017
Introduction: Previously published UK Cancer Registry data showed incidence of Neuroendocrine Neoplasms rising between 2001 and 2015. This was higher than had been thought (Genus et al). We report more recent data with more accurate coding (ICD-O-3).

#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.

#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.

#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.
