#321 Role of VEGFR-2, P53, P53R2 and Ki-67 Expression in Metastatic Carcinoid Cancer
Introduction: Ki-67 expression is a well-known prognostic factor in neuroendocrine tumors. The role of modified expression of p53, p53R2 and VEGFR2 in this disease’s liver metastases has not been established.

#1455 Expression of Mutated p53 Protein in Gastroenteropancreatic Neuroendocrine Carcinoma (WHO G3)
Introduction: Gastroenteropancreatic neuroendocrine carcinomas (GEP-NECs) are aggressive, highly proliferating tumors. Therapeutic response to current chemotherapy regimens is usually short-lasting.

#2707 Investigating the Crosstalk between MEN1, p53 and Notch Reveals Biomarkers of Formation of Primary Pancreatic Neuroendocrine Tumors
Introduction: Pancreatic neuroendocrine tumors (PNETs) comprise a heterogeneous group of endocrine tumors. Previous studies showed that mutations of p53 are extremely rare; whereas genetic changes of MEN1 frequently occur and are correlated with poor prognosis in PNET. Still, their roles in tumorigenesis remain elusive.

#3072 Rb and p53 Status Determination by Immunochemistry Is Complementary in Routine Practice to Genetic Testing of Neuroendocrine Neoplasms
Introduction: Rb and p53 status may help distinguishing well from poorly differentiated neuroendocrine neoplasms (NEN) and may predict response to chemotherapy. Studies correlating Rb/p53 genetic and immunohistochemistry were performed on high-quality frozen samples with high throughput techniques efficient for copy number determination. This situation differs from routine practice in which small deletions may be hard to detect on formalin-fixed paraffin-embedded (FFPE) samples with a gene panel approach.

#2865 Can the Efficacy of Etoposide-Platinum Chemotherapy Be Predicted by p53/pRb Status in Grade 3 Neuroendocrine Neoplasms (G3 NEN)?
Introduction: Etoposide-platinum (EP) chemotherapy has long stood as the reference treatment of grade 3 neuroendocrine neoplasms (G3 NEN). However, G3 NEN are heterogeneous, including well differentiated tumours (NET) and poorly differentiated carcinomas of large (LCNEC) or small (SCNEC) cell type, whose identification can be challenging and response to EP be very variable, usually low in NET.

#205 Integrated Genome-Wide DNA Methylation and mRNA Expression Analysis of Pancreatic NETs Identifies Differential Activation of the Hypoxia Inducible Factor (HIF) Pathway Between Low and Intermediate Grade Tumors
Introduction: This is the first study to integrate DNA methylation and mRNA expression analysis in NETs. It is a powerful approach with which to identify disrupted biological pathways in NET pathogenesis.

#558 MANECs Among Colorectal Signet Ring Cell Carcinomas
Introduction: The mixed adenoneuroendocrine carcinomas (MANEC, WHO 2010) are neoplasms with heterogeneous morphology, whose mixed nature may be difficult to recognize.

#1161 Comparative Proteomic Analysis of Human Insulinoma and Its Clinical Implications in Pancreatic Neuroendocrine Tumors
Introduction: Insulinoma is the most common functional PNET. Its molecular tumorigenesis is largely unknown and proteomic study on insulinoma has not been reported

#1595 Pathological Features of High Proliferative Activity Neuroendocrine Tumor
Introduction: High Proliferative Activity Neuroendocrine Tumor (NET G3) is difficult to be distinguished from neuroendocrine carcinoma. However, there are differences in clinical treatment and prognosis between the two. So it is crucial to make an accurate pathological diagnosis.
