#2258 Cystic Duct Gastrinoma in a Patient with MEN1: A Case Report

Introduction: Gastrinomas are the most common functional enteropancreatic neuroendocrine tumour in MEN1 patients and are located almost exclusively in duodenum. Biliary tree gastrinomas are rare and accounted for 6 cases in literature. Only one of these cases was restricted to the biliary tree without associated duodenal gastrinomas.

#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

#1668 Classification of Lung Neuroendocrine Neoplasms (Lung-NENs) According to WHO 2010 for Gastroenteropancreatic NENs (GEP-NENs) Has Prognostic Relevance and Includes Lung-NETs G3

Introduction: The classification of lung neuroendocrine neoplasms (Lung-NENs) according to the WHO classification 2010 for GEP-NENs, including a provisional category for Lung-NET G3 with Ki67 >20%, may have prognostic implications.

#1666 Prognosis and Incidence in Pancreatic and Gastrointestinal Neuroendocrine Neoplasms with Emphasis on “NET G3”: An Analysis of 198 Cases from Japan

Introduction: Prognostic impact of well differentiated pancreatic neuroendocrine neoplasms (PanNENs) with a Ki67 >20%, provisionally called NET G3, needs to be validated and compared to poorly differentiated neuroendocrine carcinomas (NECs). Moreover, the frequency of NET G3 among gastrointestinal NENs (GI-NENs) has so far not been studied.
