#1564 Well Differentiated Pancreatic Neuroendocrine Tumors (WDPNET) G3: Does the Ki67 Really Do It All?
Introduction: WDPNET G3, although not recognized by the 2010 WHO classification are far from exceptional. They also represent a great therapeutic challenge especially since their molecular drivers are unknown.

#1557 Dual High Throughput Proteomic and Transcriptomic Screen for Predictive Biomarkers of Everolimus Sensitivity in Pancreatic NET
Introduction: mTOR inhibitor Everolimus is approved for the treatment of well-differentiated PNET. The heterogeneity of the response rate and the potential toxicity warrant predictive biomarkers.

#2108 Molecular Characterization of Primary and Metastatic Pancreatic Neuroendocrine Tumors
Introduction: Pancreatic neuroendocrine tumours (PNETs) are a heterogeneous group of rare pancreatic neoplasms often diagnosed with distant metastases, which are associated with significantly poorer prognosis. Recurrent somatic mutations, chromosomal aberrations and gene expression signatures in PNETs have been described, but the clinical significance of these molecular changes is still poorly understood, and the clinical outcomes of PNET patients remain highly variable.

#2287 Mitochondrial or Aerobic Glycolysis Oriented Metabolism May Define Pancreatic Neuroendocrine Tumors (PanNET) Resistance to mTOR-Targeting Therapies
Introduction: The mTOR inhibitor Everolimus is approved for the treatment of PanNET and no predictive biomarker is available. mTOR is a central node controlling mitochondrial and aerobic glycolytic metabolisms.

#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.

#2293 Genomic and Transcriptomic Characterization of Aggressive Well Differentiated Pancreatic Neuroendocrine Tumors (WD PanNET)
Introduction: While the genomic and transcriptomic landscape of low proliferating PanNET have been well studied, pathways driving aggressive WD PanNET are still unclear.

#2192 Immunohistochemical Profiles in 81 Patients with Resected Insulinomas
Introduction: Ninety percent of insulinomas are benign. However, there are no well-defined immunohistochemical criteria that can distinguish a benign from a malignant insulinoma

#447 SOMscan: Towards a Ga-68-labeled Pan-Somatostatin PET Imaging Probe Based on SOM230 (Pasireotide)
Introduction: The somatostatin receptor subtype sst2 is largely expressed on neuroendocrine tumors. However, current clinical studies indicate that the subtypes sst1, 3, 5 are of substantial relevance as well.

#1284 Pharmacokinetic (PK) Differences Between Subcutaneous and Intramuscular Administration of Lanreotide: Results from a Phase I Study
Introduction: Data have shown that 38% of intended gluteal intramuscular (IM) injections with long-acting release octreotide were mistakenly given subcutaneously (SC); in carcinoid syndrome patients, this significantly increased the rate of flushing (P=0.005; Boyd 2013, Pancreas). Lanreotide depot(LD) recently became FDA-approved for the treatment of gastroenteropancreatic neuroendocrine tumors (120 mg Q4W) as a deep SC injection.
