#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.

#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.

#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.

#1429 Evaluate the Accuracy of Pathological Diagnosis on Biopsy Specimens from Gastrointestinal Neuroendocrine Tumors
Introduction: Gastrointestinal neuroendocrine neoplasms (GI-NENs) is a highly heterogeneous tumor. The accuracy of pathological diagnosis on the biopsy is crucial for GI-NENs but rarely investigated

#2033 Ki-67 and Presence of Liver Metastases Predicts Progression in Pancreatic Neuroendocrine Neoplasms (pNENs)
Introduction: In pancreatic neuroendocrine neoplasms (pNENs), size ≤20 mm and Ki-67 ≤2% suggest indolent behavior, but no factor alone can predict prognosis.

#2835 Primary Hepatic Neuroendocrine Carcinoma: Case Report and Literature Review
Introduction: Primary hepatic neuroendocrine carcinoma (PHNEC) is an extremely rare neuroendocrine carcinoma (NEC) that originate from the liver. The diagnosis of PHNEC remains challenging because of its rarity, and its lack of unique clinical features. Available treatment options for PHNEC include surgical resection of the liver tumor(s), radiotherapy, liver transplant, transcatheter arterial chemoembolization (TACE), and administration of somatostatin analogues.
