#2852 Diagnostic Accuracy of Endoscopic Ultrasound-Fine Needle Aspiration (EUS-FNA) in the Evaluation of Pancreatic Neuroendocrine Neoplasms (PNEN) Grading
Introduction: Prognosis of pNENs depends on staging and grading, based on the cyto-histological Ki67 labelling; EUS-FNA is considered the gold standard technique to obtain it in pre-therapeutic setting

#859 Pancreatic Neuroendocrine Tumors (PNETs): Role of Endoscopic UltraSound-Fine Needle Aspiration (EUS-FNA) and Accuracy of Ki-67 Measurement on Cytological Specimens
Introduction: The role of EUS-FNA in preoperative diagnosis and grading of pNETs is well-established, but it is unclear how Ki-67 expression on cytological specimens obtained by EUS-FNA reflects the value found on surgical specimens.

#126 Assessment of the proliferation marker Ki-67 by endoscopic ultrasound guided-Fine Needle Aspiration (EUS-FNA) in pancreatic endocrine tumors: A comparative analysis with histology of the surgical specimen
Introduction: Assessment of the proliferative index by Ki-67 immuno-labelling is an important prognostic parameter for the biologic behavior of digestive neuroendocrine tumors, usually established on the histological specimen obtained after surgery or macro-biopsy. However, small pancreatic endocrine tumors (PET) are more and more often recognized by CT/MRI and diagnosed by EUS. The value of Ki-67 labelling index (Ki-67-LI) on fine needle aspiration (FNA) is not well-established in this setting, although regularly assessed.

#2222 Biliary Mixed Neuroendocrine-Nonneuroendocrine Neoplasms: A Series of Four Cases with Review of Literature
Introduction: Mixed Neuroendocrine-Nonneuroendocrine Neoplasms (MiNENs) are rare tumors comprising of both adenocarcinoma and neuroendocrine component, at least 30% of each in the lesion.

#91 Endoscopic ultrasound of 66 insulinomas
Introduction: Ultrasound is the virtual representation of the morphology of organs and tissues. Endoscopic ultrasound can be used in detailed scanning of pancreas and preoperative topical diagnostics of insulinomas. Insulinoma requires surgical treatment in all cases. This fact allows control of preoperative diagnostic methods.

#543 Endoscopic Ultrasound-Guided Fine Needle Tissue Acquisition (EUS-FNTA) Using a 19-G Needle for Histological Grading of Pancreatic Endocrine Tumors (PETs): A Prospective Study
Introduction: EUS-FNTA is increasingly used in the diagnosis of pancreatic endocrine tumors (PETs). Ki-67 expression, an important prognostic factor according to the WHO classification, is difficult to be determined on cytological specimens.

#1889 FNA Under Percutaneous Ultrasound or Endoscopic Ultrasound for Pre-Operative Diagnosis and Grading Determination in PanNET. Are They Reliable to Define a Tailored Therapy?
Introduction: Fine-needle aspiration cytology (FNA)under percutaneous ultrasound guided (pUS)or endoscopic ultrasound(EUS)control is a minimally invasive technique allowing diagnosis and grading determination in pancreatic neuroendocrine tumors (PanNET).Obtaining a correct cytological diagnosis is crucial for a tailored therapy

#1519 Gastric Type I Neuroendocrine Tumors Endoscopic Treatment Options
Introduction: From 1998 till 2014 in our institution we have identified 72 patients with type I gastric neuroendocrine tumors (NET), 42 of them, without regional or distant metastases, undergone different types of endoscopic treatment.

#2223 Diagnostic Dilemma in a Patient with Recurrent Hypoglycaemia: An Unusual Case
Introduction: Recurrent hypoglycemia is a part of Whipple’s triad and usually points towards insulinoma as a cause. Presence of metastasis is uncommon in Insulinoma, and other causes should be ruled out.

#199 Magnetic Resonance Imaging (MRI) v. Endoscopic Ultrasonography (EUS) for the Detection of =10-mm Pancreatic Tumors in Multiple Endocrine Neoplasia Type 1 (MEN1). A GTE Study
Introduction: In MEN1, the main risk factor of metastases is pancreatic tumor size. We and others recommend limiting surgery to pancreatic tumors >20 mm or growing based on their size measured with EUS.
