#2951 Analysis of Discordance between Biopsy Grade and Surgical Pathology Grade in Resected PanNEN Patients

Introduction: In PanNEN cases, treatment strategies are decided by tumor localization, volume and grade. In unresectable or metastatic cases, tumor grade is determined by biopsy specimen obtained from EUS-FNA and diagnostic accuracy of biopsy according to WHO classification 2017 is important for decision making of treatment.

#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

#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.

#2185 Nonfunctional Pancreatic Neuroendocrine Tumor (NF PNET) Imaging and Evaluation Using 18F-FDG and 68Ga- DOTANOC-PET/CT: Initial Data of a Prospective Study

Introduction: Predicting aggressive behavior of NF PNET still remains controversial. It is known that lymph node metastases are rare but possible also on small (1-2 cm) NF-PNET. Positive 18F-FDG-PET/CT avidity is associated with poor prognosis in NETs.

#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
