#3007 An mRNA-based Classifier Identifies PanNETs with Different Clinicopathological Characteristics

Introduction: Pancreatic neuroendocrine tumors (PanNETs) are a heterogeneous group of neoplasms that varies from indolent to highly aggressive diseases. Previous studies have suggested alterations of ATRX/DAXX as biomarkers of dismal prognosis, yet inconclusive data (especially in the metastatic setting) prevent those biomarkers to be used as routine clinical tests.

#2922 Clinicopathological Characteristics of Borderline Pulmonary Neuroendocrine Neoplasms

Introduction: According to the WHO 2015 classification pulmonary neuroendocrine neoplasms (NENs) are subdivided in carcinoids and neuroendocrine carcinoma (small cell lung carcinoma and large cell neuroendocrine carcinoma (LCNEC)), based on the presence of necrosis and mitotic index (MI). However, in some NENs a discrepancy is observed between grade of differentiation and proliferation rate.

#2256 Assessment of the Serum Levels of the Soluble Vascular Cellular Adhesion Molecule-1 (sVCAM-1) in Patients with Neuroendocrine Neoplasms

Introduction: Tumor growth and the ability to metastasize is a multistage process involving interactions between cancer cells and the vascular endothelium. These interactions have been reported to be mediated by various molecules including sVCAM-1. We have previously shown elevated serum concentration of sVCAM-1 in 82 neuroendocrine neoplasms (NEN) compared to controls. Here, we present results of the extension of the previous study.
