#2743 Mimics of Neuroendocrine Neoplasms Identified in a Single Consultation Center between 2009 and 2019
Introduction: Immunohistochemical expression of synaptophysin (SYN), chromogranin (CgA) and cytokeratin are essential for diagnosis of NENs. Non-NENs, however, may occasionally also express NE-markers and cytokeratin and cause diagnostic difficulties.

#2824 Patient and Nurse Satisfaction with the New Lanreotide Autogel Pre-Filled Syringe in Neuroendocrine Tumors (NET): A Prospective Study (SONATE)
Introduction: A new syringe (NS) for the delivery of lanreotide autogel was approved in Oct 2018 in France. The NS includes updated features (larger flanges, more robust plunger) intended to ease the injection.

#2855 Whole Exome Sequencing Reveals the Monoclonal Origin of Gastric Mixed Adenoneuroendocrine Carcinomas
Introduction: Gastric mixed adenoneuroendocrine carcinomas (g-MANECs) are rare neoplasms consisting of adenocarcinoma and neuroendocrine neoplastic components. G-MANECs show more malignant characteristics than gastric adenocarcinomas, while molecular mechanisms underlying the co-existence of the two components remains unknown.

#2902 DNA Methylation Analysis of the PDX1 Gene Can Be Used for PNET Subtyping and Has a Possible Prognostic Value
Introduction: Estimating prognosis of pancreatic neuroendocrine tumor (PNET) patients remains challenging. Mutation status of DAXX/ATRX/MEN1, histone modification patterns and immunohistochemistry for relevant transcription factors, including PDX1, were recently used to perform subtyping and distinguished two main types, A and B. These subtypes are linked to cell-of-origin and associated with clinical outcome.

#2955 Development of an EORTC Quality of Life Questionnaire for Patients with Pancreatic Neuroendocrine Tumours: Phases 1-3
Introduction: Measuring quality of life (QoL) in Pancreatic Neuroendocrine Tumours (pNET) involves assessing issues from symptoms, disease and treatment. The validated gastrointestinal NETs module (EORTC QLQ-GINET21) is used with EORTC QLQ-C30 but there are concerns it inadequately measures QoL in pNET.

#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.

#14 Radioguided surgery in NET: First impression with Ga-68 labeled somatostatin analogues
Introduction: Neuroendocrine tumors (NET) constitute a heterogenous group of neoplasms. The development of Gallium-68-labeled somatostatin analogues, such as DOTA-NOC or DOTA-TOC, PET/CT have dramatically improved the diagnosis of neuroendocrine tumors. Surgery remains the treatment of choice for localized disease as well as metastatic disease. The aims of surgery are: improvement of symptoms, reduction of tumor mass / burden and to give better quality of life to patients. Recurrent laparotomies often lead to multiple adhesions and altered anatomy. So it is increasingly difficult for imaging physicians and surgeons to separate non-malignant from malignant tissue.

#20 Paraneoplastic antigen Ma2 (PNMA2) auto-antibodies as biomarkers for early small intestine neuroendocrine tumors detection
Introduction: Small intestine neuroendocrine tumors (NETs) comprise well-differentiated NET (benign carcinoid), well-differentiated neuroendocrine carcinoma (malignant carcinoid) and poorly differentiated neuroendocrine carcinoma (NEC). The majority of NET patients have developed liver metastases at the time of diagnosis and surgery is then seldom curative. Novel predictive, diagnostic and prognostic markers are thus needed to improve our capabilities to diagnose and cure these tumors. We have previously identified six novel marker genes for neuroendocrine tumor cells by using Affymetrix microarrays and advanced bioinformatics. One of this markers, the paraneoplastic antigen Ma2 (PNMA2), which is normally expressed only in nervous tissue, can in the process of carcinogenesis be detected in tumors located outside the nervous system. The finding that Ma2 is expressed in small intestine neuroendocrine primary tumors and their metastases made it interesting to screen whether antibodies against Ma2 are present in the serum of NET patients.

#81 Gastroenteropancreatic neuroendocrine tumors (GEP-NETs): our experience in a multidisciplinary team in a university hospital
Introduction: Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) have a low incidence and prevalence representing < 2% of all gastrointestinal tumors with a heterogeneous biological behavior and an often complex management.
