#2781 Case Report: Whole Exon Sequencing of Primary Lesion and Metastatic Liver Lesion in Pancreatic Neuroendocrine Tumor

Introduction: Pancreatic neuroendocrine neoplasms(NENs) are classified into neuroendocrine tumors (NET) G1, G2, G3, and neuroendocrine carcinoma (NEC), which are different pathogenesis. The two kinds of tumors that occurs in the same lesion in one patient is very rare. We found high grade neuroendocrine neoplasms(NENG3) with a diameter of 0.1 cm in a patient with a pancreatic NETG2 (1.7 cm in diameter). The cells were significant atypia with Ki67 index of 60%, focal necrosis, while metastatic nodules in the liver (12, 0.1-1.1 cm in diameter) were all high grade NENG3.

#1290 PD-L1 Expression is Associated with Grade of Neuroendocrine Tumors

Introduction: Neuroendocrine neoplasms are divided into well-differentiated neuroendocrine tumors (WDNETs) and poorly differentiated neuroendocrine carcinomas (PDNECs).The correlation between Gastroenteropancreatic Neuroendocrine Neoplasms (GEPNENs) and immunocheck point molecule-PD-L1 is still unclear now.
