#1377 Metastatic Neuro Endocrine Tumors: Epidemiological Characteristics, Management and Prognostics Factors. Results from an Inter-Regional Network in France between Upper and Lower Normandy
Introduction: Metastatic neuro-endocrine tumors (MNETs) are rare and their management are complex. To standardize therapeutic strategies in France, a national network of clinicians (RENATEN) has been created, composed of 17 expert centres.

#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.

#1242 Epidemiological Characteristics from a Single Centre Database. Cohort of 1301 Neuroendocrine Tumor Patients: Is There an Association Between Age and Grade of NET?
Introduction: There is limited data related to epidemiology of NETs and patient survival. For many cancers younger age of diagnosis can be associated with worse survival.

#793 Experience of a Single Italian Center with NET Patients
Introduction: The management of neuroendocrine tumors involves a multidisciplinary approach, so in 2004 the Endocrinology and Metabolic Unit developed a local/regional network to manage NET patients and to increase physician awareness of the disease.

#134 Gastrointestinal neuroendocrine tumors: tumor characteristics and long-term clinical outcome in the German NET registry
Introduction: Prognosis of neuroendocrine tumors (NETs) has been difficult to predict due to heterogenous tumor biology, various classification systems, and lack of reliable and recent data due to the rarity of these tumors.

#363 Clinicopathological characteristics are capable of predicting long-term outcome of gastrointestinal neuroendocrine tumours in Germany
Introduction: Neuroendocrine tumours (NET) are a rare and heterogeneous group of neoplasm. Throughout the last decades the classification of NET has been both difficult and incoherent. Therefore making prognostic straticifation often difficult.

#1585 Incidence and Characteristics of Ileo-colonic Neuroendocrine Tumours Identified in the UK Bowel Cancer Screening Programme
Introduction: Colorectal cancer is the third most common cancer in the UK this had led to development of the bowel cancer screening programmes (BCSPs).There are few epidemiological data on rectal or ileal NETs diagnosed in BCSPs.

#412 Single Institutional Series of Neuroendocrine Tumors Managed in the Australian Capital Territory
Introduction: Neuroendocrine tumors (NETs) have been regarded as indolent tumors with significantly variable clinical behavior. Limited information is available on long-term clinical outcome and clinically applicable prognostic factors.
