Clinicopathological Features of the High Grade Pancreatic Neuroendocrine Neoplasms Abstract #2133

Introduction: The high grade pancreatic neuroendocrine neoplasms (PanNENs) include well-differentiated tumors (WD-NETs) with elevated proliferation and poorly differentiated carcinomas (PD-NECs).
Aim(s): The aim of the study was to assess clinicopathological features and survival outcomes of PanNEN that are G3 by Ki67 index.
Materials and methods: The study included 130 resected PanNENs, which were reviewed for morphology and immunohistochemistry and graded according to the WHO 2017 criterions. 20 cases were selected as study high grade (G3) group. The results were correlated with clinicopathologic data, overall (OS) and disease-free survival (DFS).

#33 Survival of Neuroendocrine Tumour Patients in Newcastle NHS Foundation Trust
Introduction: Neuroendocrine tumors (NETs) are rare neoplasms, with an incidence of 2-2.4 per 100,000, which derive from the neurones and epithelial cells of the diffuse neuroendocrine system. Neuropeptide-secreting NETs may present with overt clinical symptoms including abdominal pain, flushing and diarrhoea, whereas non-functioning NETs may be asymptomatic or present with obstructive symptoms. In Newcastle NHS Foundation Trust, NET patients are managed with a multi-disciplinary approach, according to UK and European NET guidelines.

#106 Gastroenteropancreatic neuroendocrine tumors: single institution clinicopathological study
Introduction: Neuroendocrine cells are widely distributed throughout the body, and neoplasms from these dispersed cells can arise at many sites. They are distinguished into two broad categories: 1) Tumors identified as small cell lung carcinomas with biology and natural history of a high-grade malignancy and characteristics of small cell undifferentiated or anaplastic appearance by light microscopy. The WHO categorizes these tumors as poorly-differentiated neuroendocrine carcinomas; 2) Well-defined neuroendocrine tumors (NETs) with variable, but most lyindolent biologic behavior and characteristic well-differentiated histologic features. The majority arise in the gastrointestinal tract and collectively they are referred as gastroenteropancreatic neuroendocrine tumors (GEP/NETs). They include carcinoid tumors, pancreatic islet cell tumors (gastrinoma, insulinoma, glucagonoma, VIPoma, somatostatinoma), paragangliomas, pheochromocytomas, and medullary thyroid carcinomas. The WHO classifies the GEP/NETs as well-differentiated NETs (carcinoid tumors) if they are noninvasive and have benign behavior or uncertain malignant potential. In contrast, GEP/NETs with characteristics of low-grade malignancy with invasion of the muscularis propria or beyond, or metastases, are characterized as well-differentiated neuroendocrine carcinomas (malignant carcinoids). Pancreatic islet cell tumors, whether functioning or not, are classified as well-differentiated NETs or well-differentiated neuroendocrine carcinomas, due to the (depending on) histologic characteristics. The WHO classification for gastroenteropancreatic NETs based on stage (ie size and presence of metastases) and grade (mitotic rate, perineural and lymphovascular invasion, Ki-67 proliferative index) categorizes them as well-differentiated NETs, e.g., carcinoid tumors, or as well-differentiated neuroendocrine carcinomas.

#110 Slug represents an important regulator of E-cadherin expression in neuroendocrine tumor cells of the pancreas
Introduction: Neuroendocrine tumors of the pancreas form an inhomogenous group of epithelial neoplasms. They differ from other types of pancreatic cancers by showing an extended survival of patients, which is due to a mostly slow proliferation rate of the tumor. However, some of these neuroendocrine tumors are characterized by an early onset of metastases, which cannot be predicted by any available method. The epithelial to mesenchymal transition (EMT) represents a central part of cell migration and metastasis. During EMT, cells loosen their cellular contacts, leave the tissue, and become migrating single cells. One of the integral compounds of cell adhesion represents the E-cadherin adhesion module, which contains mostly E-cadherin and several catenins. A loss of this adhesion module is associated with tumor progression, migration and metastasis in many types of cancer.

#171 Transcription Factor Signature in Pancreatic and Duodenal Neuroendocrine Neoplasms
Introduction: We recently identified ISL1 as a marker for pancreatic neuroendocrine neoplasms (P-NENs). ISL1 as well as PDX1, CDX2 and NGN3 are transcription factors (TF) involved in pancreato-duodenal development.

Introduction: Duodenopancreatic neuroendocrine tumors (NETs) are uncommon neoplasms with a wide spectrum of clinical presentation. The infrequent occurrence of these tumors makes large experiences very scarce.
