#991 Primary Neuroendocrine Tumor of Extrahepatic Bile Duct
Introduction: Biliary tract primary malignant tumors are rare neoplasms. Eighty-five per cent are cholangiocarcinomas, being in exceptional cases a neuroendocrine tumor. The absence of clinical suspiction involves a difficult preoperative diagnosis.

#724 Contrast-Enhanced Ultrasonography (CEUS) Reliably Predicts Tumor Progression in Pancreatic Neuroendocrine Tumors
Introduction: Neuroendocrine tumors (NETs) exhibit a typical vascular pattern in the arterial phase on CEUS. The role of CEUS in the prognostic evaluation of pancreatic NET (pNET) has been poorly investigated.

#37 Gastric GIST with synchronous neuroendocrine tumor of the pancreas, Case Report and Literature Review
Introduction: The Gastrointestinal Stromal Tumors (GIST) are the most common mesenchymal tumors of the gastrointestinal tract. These are rare tumors with an incidence of 15 new cases per million per year. They often occur in individuals over the age of 40 years, without gender predominance. The clinical behavior is variable and benign tumors are the most common. They can develop anywhere in the GI tract, but are more frequent in the stomach and small intestine. The primary treatment, when located, is the surgical resection, which can be complemented with the use of imatinib.
The occurrence of neuroendocrine tumors of the pancreas is rare, representing 1-5% of pancreatic cancers, and it is estimated that its incidence does not exceed 5 to one million. The tumors considered nonfunctioning (15-32% of pancreatic neuroendocrine tumors) are not associated with any syndrome, and are usually incidental. They have a slight predominance in males, and are more frequent in the 6th decade of life. Nonfunctioning tumors of islet cells are virtually all malignant tumors, and the treatment consists of surgical resection.

#630 Pancreatic Polypeptide Cell Hyperplasia Associated with Nonfunctioning Pancreatic Neuroendocrine Tumor: A Case Report

#2200 Tumor Size Correlates with Grading in Nonfunctioning Pancreatic Neuroendocrine Tumors and Is Not Age-Dependent
Introduction: Tumor growth and Ki67 value increase are associated with aggressiveness in nonfunctioning pancreatic neuroendocrine tumours (NF-PanNET), but their natural history is largely unknown. It is unknown if the evolution of NF-PanNET is time-dependant.

#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.

#1265 Prognostic Factors for Recurrence of Sporadic Pancreatic Neuroendocrine Tumors After Surgical Resection
Introduction: Pancreatic neuroendocrine tumors (PNET) are rare neoplasms with heterogeneous presentation. The diagnosis of malignancy is often difficult, and then further studies may contribute to improve prognosis criteria.

#1851 Ecological Study to Assess the Management of Gastroenteropancreatic Neuroendocrine Tumors in Spain
Introduction: Neuroendocrine tumors (NET) have widely varying characteristics, localizations, and treatments. Consequently, a multidisciplinary approach to diagnosis and treatment is necessary. Given the heterogeneous management of this disease, we conducted an ecological survey to assess usual clinical practice in Spain.

#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.
