A Comparative Analysis of Ki67 Index of the High Grade Neuroendocrine Neoplasms Arising in the Gastrointestinal Tract and the Pancreas Abstract #1286

Introduction: A common classification has been used for NET in gastrointestinal tract (GI-NET) and pancreas (P-NET), but heterogeneity has been reported in high grade tumors; well-differentiated G3 (WDG3), poorly differentiated NEC (NEC), and mixed adenoneuroendocrine carcinoma (MANEC).
Aim(s): The morphological varieties of the high grade tumors among organs are further to be studied.
Materials and methods: We reviewed morphology and Ki67 index of 230 GEP-NET; 86 (39%) GI-NET and 134 (61%) P-NET cases.

#9 Case Management of Metastatic carcinoid of the Foregut,Midgut and Hindgut:the relevance of Ki-67 prognostication
Introduction: The predictive value of tumor grade in the prognosis of carcinoid is insufficient and somehow misleading. The grade and differentiation in carcinoid tumors must be seen in conjunction with the Ki-67 index. The Ki-67 protein is a cellular marker for proliferation, present during all active phases of the cell cycle (G1, S, G2 and mitosis) and absent from resting cells (G0). It is therefore an excellent marker to determine the growth fraction of a given cell population. The Ki-67 labelling index is often correlated with the clinical course of carcinoid.

#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.

#41 Immunohisochemical evaluation of EMT regulators, E- and N-cadherin in neuroendocrine Tumors of the Gastro-Entero-Pancreativ system
Introduction: Local tumor invasion represents the first step of the metastatic cascade of carcinomas, and requires changes in cell adhesion and migration properties of tumor cells. This biologic process is known as epithelial-mesenchymal transition (EMT). One key biochemical change associated with EMT is the loss of E-cadherin expression promoted by specific transcriptional repressors such as Snail, Slug, and Twist. Overexpression of EMT inducers increases other factors, such as FoxC2, although its role in EMT is poorly understood. Neuroendocrine tumors (NETs) of the gastroenteropancreatic (GEP) system, originated from the diffuse endocrine system, represent a heterogeneous group of tumors. Their prevalence has increased substantially over the past three decades, without substantial improvements in their clinical management, and their variable clinical course cannot be predicted by common clinicopathological parameters. Thus, new prognostic markers are urgently needed.

#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.
