#72 Reduced expression of p27 and the occurrence of CpG island methylator phenotype in insulinomas
Introduction: The molecular pathogenesis of sporadic insulinoma is unclear, though some of the genes were found to be slienced by promoter methylation. CpG island methylator phenotype (CIMP) was found in a number of common tumors and correlated with loss of expression of p27, which may contribute to the tumorigenesis of the tumors.

#2958 The Blood-based Multigenomic NETest Accurately Identifies Neuroendocrine Transformed Prostate Cancer
Introduction: Neuroendocrine differentiation and an aggressive phenotype is an important feature of castration-resistant prostate cancer (CRPC). Current biomarkers are unable to detect these advanced, treatment refractory variants.

#2745 Integrative Genomic Characterization Identifies Molecular Subtypes of Lung Carcinoids
Introduction: Lung carcinoids (LCs) are rare and slow growing primary lung neuroendocrine tumors. The WHO classify LCs into atypical and typical carcinoids. Recent studies have shown that the reproducibility of LCs classification and its prognostic efficacy have high interobserver variability

#2756 Theranostic Implication of Molecular Imaging Phenotype of Well-Differentiated Lung Carcinoid by 68Ga-DOTATATE PET/CT and 18F-FDG PET/CT
Introduction: Well-differentiated pulmonary neuroendocrine tumour, classified as typical carcinoid (TC) and atypical carcinoid (AC), is a heterogenous disease with variable clinical behaviour.

#2827 Characterization of Epigenetic Modulation in Pancreatic Neuroendocrine Neoplasms
Introduction: Pancreatic neuroendocrine tumors (PanNETs) represent a rare and heterogeneous tumor entity. Despite advances in therapy cancer progression and resistance mechanisms are still challenging. Recent genome wide sequencing analyses in PanNETs identified a large number of mutated genes involved in epigenetic modulation.

#2885 Ectopic Neuroendocrine Carcinoma: An Occult Source of ACTH
Introduction: About 250 cases of ectopic ACTH-producing neuroendocrine carcinoma (ACTH-NEC) have been reported; however metastatic ACTH-NEC of unknown primary is very rare. Usually are characterized by having a large cell, small cell, poorly differentiated or anaplastic cell, and Ki-67 index between 40-90%.

#2986 Characterization of 142 Human Pancreatic Neuroendocrine Tumors: ATRX and DAXX Correlation with Clinical-Pathological Data
Introduction: Pancreatic neuroendocrine tumors (PNETs) are rare and heterogeneous neoplasms with a 10-year survival rate less than 30%. Up to 43% of them are driven by inactivating mutations in ATRX or DAXX. These are important players at chromatin remodeling, that when mutated prone cancer cells to initiate the alternative lengthening of telomeres (ALT). ALT phenotype correlates with in situ loss of expression of the proteins ATRX or DAXX and can be corroborated by telomere-FISH.

#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.

#2742 Anti-Tumor Effects of Semaphorin 4D Blockade Unravel a Novel Pro-Invasive Mechanism of Vascular Targeting Agents
Introduction: One of the main consequences of inhibition of neovessel growth produced by angiogenesis inhibitors is increased intratumor hypoxia. Growing evidence indicates that tumor cells escape from this hypoxic environment to better nourished locations, presenting hypoxia as a positive stimulus for invasion. Particularly, anti-VEGF/R therapies produce hypoxia-induced invasion and metastasis in a spontaneous mouse model of pancreatic neuroendocrine cancer, RIP1-Tag2.
