#1059 Genomic Profiling of Metastatic Gastroenteropancreatic Neuroendocrine Tumor (GEP-NET) Patients in Precision-Medicine Era
Introduction: We have conducted molecular profiling through high-throughput molecular test as part of clinical practice for patients with advanced gastrointestinal (GI) cancer, or rare cancer including gastroenteropancreatic neuroendocrine tumors (GEP-NETs).

#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.

#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.

#360 High Resolution (Epi)genomic Analysis Comparing Pulmonary Carcinoids with a Favorable and a Poor Disease Outcome
Introduction: Lung carcinoids are a heterogenous group of neuroendocrine tumors. MEN1 mutations and 11q22-q25 deletions have been implied in their tumorigenesis. Very few genome wide and methylation studies have been conducted to further elucidate molecular mechanisms underlying tumorigenesis.

#491 International Survey for the Use of Biomarkers and Molecular Imaging in Neuroendocrine Tumors (NET): What we are Using in Daily Practice
Introduction: Several guidelines have given recommendations for optimal use of biomarkers and molecular imaging. However, those guidelines’ implementation may not be always possible due to local policies or lack of access to several diagnostic studies.

#722 Isolation and Whole Genome Amplification of Single Circulating Tumor Cells in Neuroendocrine Tumors: A Pilot Study
Introduction: We have previously demonstrated that Circulating Tumor Cells (CTCs) can be detected in patients with neuroendocrine tumors (NET) and that their presence is prognostic. Downstream analysis of CTCs provides an opportunity to explore their potential as biomarker for targeted therapy. Here we present initial data which demonstrates that molecular profiling can be successfully performed on single CTCs from patients with NETs

#198 Novel Insights in Octreotide Effects on Human Neuroendocrine Cell Line CNDT2.5
Introduction: Octreotide, the first synthetic somatostatin analog available for clinical use, efficiently binds somatostatin receptors (SSRs) 2 and 5 and may transduce its effects by using SSRs.
