#2973 Robustness of Radiomic Features in 68Ga-DOTATOC PET/CT: A Monocentric Experience for Neuroendocrine Tumors
Introduction: Neuroendocrine tumors (NET) are a heterogeneous group of malignancies with varied histology, localization and behaviour.

#2996 A Head-to-Head Comparison between Two Software Packages for Hybrid Dosimetry after PRRT
Introduction: The number of dosimetry studies after PRRT is increasing, yet different methodologies are used which challenge comparison or pooling of results.

#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.

#2781 Case Report: Whole Exon Sequencing of Primary Lesion and Metastatic Liver Lesion in Pancreatic Neuroendocrine Tumor
Introduction: Pancreatic neuroendocrine neoplasms(NENs) are classified into neuroendocrine tumors (NET) G1, G2, G3, and neuroendocrine carcinoma (NEC), which are different pathogenesis. The two kinds of tumors that occurs in the same lesion in one patient is very rare. We found high grade neuroendocrine neoplasms(NENG3) with a diameter of 0.1 cm in a patient with a pancreatic NETG2 (1.7 cm in diameter). The cells were significant atypia with Ki67 index of 60%, focal necrosis, while metastatic nodules in the liver (12, 0.1-1.1 cm in diameter) were all high grade NENG3.

#3001 Early Response Assessment for Prediction of Overall Survival after Peptide Receptor Radionuclide Therapy
Introduction: PRRT response assessment is performed using RECIST, yet functional assessment using 68Ga-DOTATATE PET/CT and plasma CgA might give additional information about prediction of overall survival (OS).

#3017 Patient and Healthcare Practitioner Perspectives of Somatostatin Analogs in the Management of Neuroendocrine Tumors and Acromegaly: A Systematic Literature Review
Introduction: Somatostatin analogs (SSAs) are used to treat acromegaly and neuroendocrine tumors (NETs). Two first-generation SSAs, octreotide and lanreotide, are available to patients (pts).

#3022 Diagnostic Accuracy of 68Gallium Positron Emission Tomography (68Ga PET), Endoscopic Ultrasound (EUS) and Computed Tomography in the Assessment of Lymphnode Metastases by Nonfunctioning Pancreatic Neuroendocrine Neoplasms
Introduction: The presence of nodal metastasis is one of the most important predictive factors for recurrence after radical surgery for nonfunctioning Pancreatic Neuroendocrine Neoplasms (NF-PanNEN). Nevertheless, it is not clear which is the best diagnostic examination to identify preoperatively lymphnodal metastasis.

#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.

#3057 Epidemiological Features of Patients with NeuroEndocrine Neoplasms (NENs): Preliminary Results of an Observational Study by the Hellenic Society of Medical Oncology (HeSMO)
Introduction: NENs are rare tumors and can grow in almost all tissues. Regardless histological, molecular and imaging characteristics that are indicative of the primary origin, a significant percentage remain of unknown primary.

#3064 ALPPS for Neuroendocrine Liver Metastases Not Suitable for Conventional Hepatic Resection - Interim Analysis of the International ALPPS Registry
Introduction: Surgery is the most effective treatment option for neuroendocrine liver metastases (NELM). However, the majority of patients with NELM do not have disease that is resectable using conventional methods. Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) is a relatively novel two-stage strategy in hepatic surgery.
