#544 Second Primary Tumor in Patients with Gastroenteropancreatic Neuroendocrine Tumors (GEPNETs): Data From a Retrospective Observational Unicentric Study
Introduction: It is known that GEPNETs are associated with a high incidence of second primary tumors, especially in the context of inherited syndromes and synchronous injuries to the intestine.

#1606 Tumor Growth Rate to Assess Tumor Activity in Patients with Lung Neuroendocrine Tumors on Lanreotide Autogel: A Case-Series Analysis
Introduction: The slow-growing character of neuroendocrine tumors (NET) makes it difficult to assess treatment impact on tumor growth.

#141 Incidence of second primary tumors in patients with neuroendocrine tumors
Introduction: Based on epidemiological data from SEER 1950-1999, 22.4% cases of non-carcinoid second primary tumors have been described in patients diagnosed with neuroendocrine tumors. The incidence of this type of tumors varies, depending on the series assessed.

#2111 Biliary Neuroendocrine Tumors: A Retrospective Analysis of 28 Patients Since 1991
Introduction: Biliary neuroendocrine tumors represent less than 1% of all neuroendocrine tumors (NETs), and the related clinical study is limited.

#2288 Predicting Resectability of Primary Tumor and Mesenteric Lumps in Patients with Small Intestine Neuroendocrine Tumors
Introduction: Vascular infiltration and mesenteric fibrosis may jeopardize resection of primary tumor (PT) and mesenteric metastatic lumps (MLs) in small-intestine neuroendocrine tumors (SI-NETs).

#16 Endoglin as indicator of metastatic neuroendocrine tumors of the pancreas
Introduction: Neuroendocrine tumors of the pancreas are rare, highly vascularized tumors. Endoglin, a Transforming Growth Factor-β co-receptor, is a marker for angiogenic endothelial cells. Angiogenesis is required for tumor progression and the development of metastases. Recently, endoglin expression was found to be a prognostic marker in pancreatic carcinomas. However, the role of endoglin in neuroendocrine pancreatic tumors has so far not been studied.

#110 Slug represents an important regulator of E-cadherin expression in neuroendocrine tumor cells of the pancreas
Introduction: Neuroendocrine tumors of the pancreas form an inhomogenous group of epithelial neoplasms. They differ from other types of pancreatic cancers by showing an extended survival of patients, which is due to a mostly slow proliferation rate of the tumor. However, some of these neuroendocrine tumors are characterized by an early onset of metastases, which cannot be predicted by any available method. The epithelial to mesenchymal transition (EMT) represents a central part of cell migration and metastasis. During EMT, cells loosen their cellular contacts, leave the tissue, and become migrating single cells. One of the integral compounds of cell adhesion represents the E-cadherin adhesion module, which contains mostly E-cadherin and several catenins. A loss of this adhesion module is associated with tumor progression, migration and metastasis in many types of cancer.

#194 Pancreatic Neuroendocrine Tumors: Experience of Endocrinology Department of the University Hospital of Coimbra
Introduction: Pancreatic neuroendocrine tumors (PNETs) are uncommon neoplasms, comprising 1-2% of all pancreatic tumors. The majority are nonfunctional. Of the functional tumors, insulinomas are the most common.

#867 Mixed Adenoneuroendocrine Carcinoma (MANECs): A Rare and Challenging Subgroup of Neuroendocrine Neoplasia
Introduction: Mixed Adenoneuroendocrine Carcinomas (MANECs) are rare entities in which at least 30% of neoplastic cells are neuroendocrine in nature (WHO 2010 classification). They result either from two independent lesions that merge together or are unique lesions with different cell populations intermingled.

#1803 Type 3 Gastric Neuroendocrine Neoplasms: Relationship Between Tumor Size, Ki67 and Clinical Outcome
Introduction: Sporadic type 3 gNENs are usually malignant with high metastatic potential, mostly large, with a high grade histology. However, little is known on the relationship between tumor size, proliferative index Ki67, and clinical outcome
