#3243 The major impact of proGRP monitoring in advanced atypical lung carcinoid: A case report

Introduction: Atypical lung carcinoids (aLC) are more aggressive than typical carcinoids, metastasizing more commonly to distant sites, and require vigilant follow-up. However, the surveillance is often hampered by the non-informative Chromogranin A (CgA) levels.

#2764 Cystic Pancreatic Neuroendocrine Tumors. Can We Diagnose Them Preoperatively?

Introduction: Pancreatic neueroendocrine tumors rarely undergo cystic changes but they are often misdiagnosed as pancreatic mucinous cystadenoma, mucinous cystadenocarcinoma, serous cystadenoma, and solid and cystic papillary tumors, or pseudocyst.

#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.

#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.
