Clinicopathological Features and Survival Analysis of 98 Patients with Gastroenteropancreatic Neuroendocrine Neoplasms Abstract #1649

Introduction: To investigate the clinicopathological features and prognostic factors of 98 patients with gastrointestinal Pancreatic neuroendocrine tumors.
Aim(s): So as to improve our understanding and diagnosis and treatment level of GEP-NENs.
Materials and methods: Data of 98 patients with gastrointestinal pancreatic neuroendocrine tumors were collected from January 2008 to June 2016 in Xinjiang Tumor Hospital. Their clinical manifestations, pathological features and survival were retrospectively analyzed.

#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.

#136 Prevalence, severity and clinical outcome of malnutrition in gastroenteropancreatic neuroendocrine tumors
Introduction: Malnutrition is well-known to unfavorably influence clinical prognosis in patients (pts) with malignant diseases. However, in patients with neuroendocrine tumors (NET) prevalence and outcome of malnutrition are unknown although the gastroenteropancreatic system is most frequently involved.

#410 Pancreatic Neuroendocrine Tumors: Retrospective Analysis Of 44 Cases
Introduction: Neuroendocrine tumors (NETs) are heterogeneous neoplasms. Pancreatic NETs (pNETs) have a broad spectrum of features. Bioamines and peptides production distinguish functional from nonfunctional tumors.

#432 Ten Years of Gastroenteropancreatic Neuroendocrine Tumors (GEP-NETs): Evolution of Classification and Correlation with Follow-up in 50 Patients
Introduction: In the last decade, GEP-NET nomenclature has been twice reviewed. The 2000 WHO classification had poor prognostic power in well-differentiated (WD) neoplasms which led to the introduction of two new important parameters: grade and stage, by ENETS; the former became part of the new 2010 WHO classification.
