#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.

#2886 Risk Factors for Short Recurrence-Free Survivals after Resection of PanNET Liver Metastasis: Single Institutional Analysis

Introduction: Although the treatment of PanNEN has improved survivals with development of pharmacotherapy recently, surgery is the first choice if curative resection is expected to be achieved. However, most of the patients undergo recurrence after resection of the liver metastasis even after curative resection. Therefore, it is important to identify who gains longer RFS by resection.
