A Better Ki-67 Index Cutoff to Redefine Low Grade NET and High Grade NEC in Grade 3 Gastroenteropancreatic Neuroendocrine Neoplasms Abstract #1693

Introduction: Heterogeneity of Grade 3 (G3) gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) was reported and well-differentiated G3 NET (neuroendocrine tumor) was classified by previous studies.
Aim(s): To evaluate the role of Ki-67 index in the heterogeneity assessment of G3 patients and to identify prognostic factors for G3 patients.
Materials and methods: Clinical data of 223 patients with G3 GEP-NENs presenting to the Wuhan Union Hospital and the First Affiliated Hospital of Sun Yat-Sen University from 2009 to 2015 was analyzed.

#28 Prognostic Clinicopathologic Factors in Longitudinally Followed Patients with Metastatic Small Bowel Carcinoid
Introduction: Neuroendocrine tumors demonstrate heterogeneous behavior based upon site of origin and specific histology. Even after controlling for anatomic location, disease stage and histologic grade, registry studies show persistent diversity of outcome in patients with midgut 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.

#87 Alterations of E-cadherin, beta-catenin and caveolin-1 expression in gastroenteropancreatic neuroendocrine tumors
Introduction: Gastroenteropancreatic neuroendocrine tumors (GEP NETs) comprise a heterogeneous group of neoplasm with different histological patterns and biological behavior. Only limited information is available on immunohistochemical prognostic factors of disease. Alterations in the cell-cell adhesion system are closely associated with cell invasion and metastasis in many malignancies, including those of endocrine origin. Abnormal expression of E-cadherin and beta-catenin has been reported to play an important role in these processes. Caveolin-1 has recently been identified as a tumor metastasis modifier factor, which might increase the cell metastasis potential through the interaction with E-cadherin. However, the role of caveolin-1 in GEP NETs cell invasion remains unknown.

#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.
