#967 Correlation Between Genomic Imbalances, Cell Proliferation and Tumor Size in Sporadic Pancreatic Neuroendocrine Tumors
Introduction: The pathogenesis of sporadic pancreatic neuroendocrine tumors (pNET) is poorly understood.

#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

#2272 Enhancing Diagnostic Precision Through Combined Genomic and Histopathological Analysis of Pancreatic Neuroendocrine Tumors
Introduction: Diagnostic differentiation of uncommon pancreatic malignancies can be challenging, but is essential for accurate clinical management; genomic analysis may provide a tool for making this critical distinction.

#2281 A Novel Classification of Pancreatic Neuroendocrine Tumors (pNETs) Guided by Genomics
Introduction: NET outcomes differ by primary site. Yet pNETs are classified using a generic GI grading system.

#2896 Comparative Genomic Analysis of High Grade Neuroendocrine Neoplasms across Diverse Organs
Introduction: Grade 3 neuroendocrine neoplasms (G3 NENs), if poorly differentiated, have a median survival of 10-19 months. Little is known regarding biologic differences between G3 NENs from different primary sites, most commonly GI and lung.

#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).

#2297 Merkel Cell Carcinomas in New Zealand: Virus or Ultra Violet?
Introduction: Merkel Cell Carcinoma (MCC) is a rare Neuroendocrine skin tumour. MCC behavior is more aggressive than the more common Melanoma, with treatments often restricted to surgery or radiotherapy, although immunotherapy holds promise overseas. In 2008, a USA study identified an oncogenic polyomavirus (MCPyV) present in eight of ten tested MCC tumours. Studies from across Europe and the USA confirmed MCPyV presence in ~80% of all MCCs. However, a cohort from Australia found a rate of just 24%, suggesting an alternative mechanism; ultra violet (UV) exposure was suspected and later confirmed using genomic mutational signature analysis. Are these are two separate diseases, requiring different clinical management strategies for best patient outcomes?

#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.
