#837 Does Biopsy Reliably Identify Grade In Gastroenteropancreatic Neuroendocrine Tumors?
Introduction: A new proliferation-based grading system has proved important in establishing prognosis and guiding therapy in gastroenteropancreatic neuroendocrine tumors (GEP-NETs). Biopsies are often performed for grading but little is known about their reliability in assigning grade.

#1088 Functional Imaging Tests versus Computed Tomography Scan: Detection of New Metastases and Clinical Usefulness in Digestive Neuroendocrine Neoplasms Follow-Up
Introduction: Digestive Neuroendocrine Neoplasms (DNENs) express in 80% of cases somatostatin receptors (SSTRs) detected by functional imaging tests (FITs). FITs are needed at diagnosis to define therapy but their role in follow-up (FU) is unclear

#3015 Biopsy Specimen Diagnosis in Pulmonary Carcinoids, A Shot in the Dark
Introduction: Pulmonary carcinoids (PCs) are rare well-differentiated neuroendocrine tumors, which can be separated into typical carcinoid (TC) and atypical carcinoid (AC). Advised treatment for local carcinoid disease is surgical resection using lobectomy, while parenchymal saving strategies such as sub-lobar or endobronchial resection might be considered for TC. In general, pre-operative diagnosis using a (transbronchial/transthoracic) biopsy sample is performed to demonstrate malignancy. However, TC and AC classification can solely be performed on surgical resection specimens, which may challenge pre-operative treatment decisions.

#1852 Is Ki67 Index in Biopsy Tissue Truly Reflect Grading of Pancreatic Neuroendocrine Neoplasm?
Introduction: Ki67 index is essential for progression and treatment of pancreatic neuroendocrine neoplasm (pNEN). For advanced pNEN patient(pts), Ki67 scoring by core/fine-needle biopsy is used to evaluate pNEN pts’ grade.

#688 Does Small Mean Benign? Not for the WHO 2010 Classification of Gastrointestinal Neuroendocrine Tumors (NETs): A Case Report of a Small Rectal Neuroendocrine Neoplasm (NEN) with Distant Metastatic Spread
Introduction: The gastrointestinal tract is the most common site of primary NETs, just over a quarter of which are rectal. According to the WHO 2000/2004 non-functioning NETs, ≤2cm with no muscularis propria or vascular invasion are classified as well differentiated (WD) NET with benign behavior. However, several case series report metastatic spread from NETs in this category. In 2010, a new WHO classification was introduced with the premise that all NETs were considered malignant with metastatic potential.

#2951 Analysis of Discordance between Biopsy Grade and Surgical Pathology Grade in Resected PanNEN Patients
Introduction: In PanNEN cases, treatment strategies are decided by tumor localization, volume and grade. In unresectable or metastatic cases, tumor grade is determined by biopsy specimen obtained from EUS-FNA and diagnostic accuracy of biopsy according to WHO classification 2017 is important for decision making of treatment.

#536 Orexins Exert a Pro-Apoptotic Effect on Neuroendocrine Tumors (NETs) in an Ex Vivo Culture Model of Tissue Slices
Introduction: Ex vivo culture models of tissue slices are suitable to test the effect of antitumor agents in human tumors. The orexins are neuropeptides binding to G protein-coupled receptors (OX1-R and OX2-R), exerting a pro-apoptotic effect in human colon and pancreatic cancer cell lines.
