#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.

#1670 A Successful Case of Controlling the Multiple Distant Metastasis of Pancreatic G2 NET with Local Therapy Combined with Systemic Pharmacotherapy

Introduction: Several systemic pharmacotherapies could be applied to multiple metastatic pancreatic neuroendocrine tumor (PNET). However, we have not determined how to coordinate ‘local’ therapy such as salvage surgery and transarterial chemoembolization with systemic pharmacotherapies for these multiple metastatic PNET.
