#928 Clinical Analysis of 245 Patients with GEP-NETs: A Single-Institution Analysis (2002–2013) in South China
Introduction: GEP-NETs are the most common types of NET, accounting for about 67.5% of total NET. But so far, there have been no related statistics of Chinese patients with GEP-NET. Here, we performed a retrospective study in South China to provide clinical characteristics of GEP-NET.

#1660 The Clinicopathological Characteristics of Small Intestinal Neuroendocrine Neoplasms: A Multicenter Retrospective Study from China
Introduction: Small intestinal NEN (SI-NEN) is much rarer in Asian countries. Hence, the clinicopathological characteristics of SI-NEN are still unknown in Asian population.

#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.

#57 Clinical and demographic characteristics in patients newly diagnosed with neuroendocrine tumors (NET)
Introduction: Neuroendocrine tumors (NETs) are tumors that form from cells that release hormones in response to a signal from the nervous system. These tumors may secrete higher-than-normal amounts of hormones, which can cause many different symptoms.
