#78 The diagnostic and prognostic value of elevated proGRP levels in well- and moderately differentiated neuroendocrine tumors
Introduction: Chromogranin A (CgA) is the most frequently used marker in well- (grade 1) and moderately (grade 2) differentiated NETs. Although CgA is a more sensitive marker than the 5-HIAA, which was widely used until the last decade, CgA has some limitations. False-positively elevated CgA may occur in renal impairment, atrophic gastritis and during treatment of proton-pump inhibitors. Progastrin-releasing peptide (proGRP) was recently reported as a promising tumor marker for small cell lung cancer. Limited data suggests that ProGRP may be a potential tumor marker in NE tumors.

#2181 Using Adult Stem-Cell Derived Organoids to Model Neuroendocrine Tumor Growth
Introduction: Neuroendocrine tumors (NETs) are a genetically diverse set of rare tumors, which have limited treatment options. The development of more effective therapies for NETs has been limited in part by the absence of in vitro and in vivo models that accurately represent the heterogeneity of these tumors.

#2982 Comprehensive Molecular Analysis Identifies Driver Mutations in Metastases of Sporadic Well-Differentiated Neuroendocrine Tumours of the Small Intestine
Introduction: Small intestinal neuroendocrine tumours (SI-NETs) represent a heterogenous group of tumours. The molecular mechanisms which contribute to progression of SI-NETs are poorly elucidated. They are considered to be molecularly distinct from neuroendocrine carcinomas (NECs), which share oncogenic pathways with adenocarcinomas.

#653 Interobserver Variability of Pulmonary Carcinoids
Introduction: Lung carcinoids are neuroendocrine tumors histopathologically classified into typical (TC; no necrosis, <2 mitoses/2 mm2) and atypical (AC; necrosis or 2-10 mitoses/2 mm2). Identification of mitoses may be hampered by the presence of apoptotic cells, and reported prediction of prognosis based on histopathology varies, especially for ACs.

#1778 Chemotherapy for Pulmonary Large Cell Neuroendocrine Carcinomas: Does the Regimen Matter?
Introduction: Metastatic pulmonary large cell neuroendocrine carcinoma (LCNEC) is a rare disease and the most effective chemotherapy regimen is debated, i.e. small cell lung carcinoma (SCLC) or non-small cell lung carcinoma (NSCLC) chemotherapy.

#2738 Patient-Derived Organoid Models of Human Neuroendocrine Carcinoma
Introduction: Gastroenteropancreatic neuroendocrine carcinoma (GEP-NEC) is a poorly understood disease with limited treatment options. Due to its low incidence and wide tissue distribution few representative preclinical models are available

#2977 Predicting Survival in Patients with a Neuroendocrine Tumor of the Small Intestine (SI-NET)
Introduction: SI-NET comprise the largest group of neuroendocrine tumors. Because of their heterogeneity, predicting survival has proven challenging. A nomogram (NG) to assess SI-NET disease specific survival (DSS) has been developed in 2010 by Modlin, et al. based on analysis of retrospective data from the Surveillance, Epidemiology and End Results (SEER) database.

#3049 Organoid Models of Neuroendocrine Cell Growth and Tumorigenesis
Introduction: A paucity of in vitro and in vivo models has limited the study of Neuroendocrine neoplasms (NENs). Moreover, little is known about normal neuroendocrine (NE) cells and how they contribute to NEN formation.

#1418 Extra-Pulmonary Neuroendocrine Carcinomas: A National Population Based Study
Introduction: Extra pulmonary neuroendocrine carcinomas(EPNEC) are rare tumours, this implies lack of knowledge on the burden.

#1184 A National Pathology Registration Analysis of Applied Terminology in Pulmonary Neuroendocrine Tumors/Carcinomas: Is the WHO 2004 Classification in Line with Clinical Practice?
