The Distinctive Character of Micro-Vasculature and Immune Cell Infiltration in Cystic Pancreatic Neuroendocrine Tumors Abstract #2693

Introduction: Hypervascularity is main character of pancreatic neuroendocrine tumors (PanNETs), cystic PanNET (CPanNET) are unique type of PanNETs for which the microenvironment remains unknown.
Aim(s): To compare the microvessel density (MVD), microvessel integrity (MVI) and immune cell infiltration between CPanNETs and solid PanNETs (SPanNETs).
Materials and methods: Data from 301 SPanNET and 36 CPanNET patients at a high-volume institution were evaluated. CD4, CD8, CD11c, CD15, CD20, CD68, CD34 and α-SMA expression were assessed by Immunohistochemistry and Immunofluorescent Double Staining.

#2682 PAK4-NAMPT Dual Inhibition as a Novel Strategy for Therapy Resistant Pancreatic Neuroendocrine Tumors
Introduction: Pancreatic neuroendocrine tumors (PNET) remain an unmet clinical need. In this study, we show that targeting both nicotinamide phosphoribosyltransferase (NAMPT) and p21-activated kinase 4 (PAK4) could become a synthetic lethal strategy for PNET.

Introduction: Because of the low incidence, nonspecific symptoms at presentation, lack of awareness, and non-uniform classifications, gastroenteropancreatic neuroendocrine tumors (GEP-NETs) remains a poorly understood disease, and delayed diagnosis is common among patients with GEP-NETs.

#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.
