#1006 The Use of Endoluminal Stents to Overcome Vascular Obstruction Arising from Mesenteric and Retroperitoneal Neuroendocrine Metastases
Introduction: Gastroenteropancreatic neuroendocrine tumors (GEP-NET) often metastasise to lymph nodes. Nodal metastases from neuroendocrine tumors in the distal small intestine commonly (>50%) develop in the mesentery and are often centred at the mesenteric root surrounding the major vessels supplying the bowel. Compression of these vessels, by the nodes or associated fibrosis, can lead to severe symptoms such as pain (secondary to bowel ischaemia ), ascites (from superior mesenteric vein obstruction) and bowel perforation. In view of the often indolent nature of GEP-NET, symptoms from lymph node masses can persist for years, causing significant morbidity and early mortality.

#1078 Somatostatin Responsive ACTH and Precursor Excess in a Midgut Mesentery NET
Introduction: ACTH production from a midgut mesentery NET is extremely rare (1). A 62y old woman presented with hypokalaemia (2mmol/L) and hyperpigmentation, 11y after surgery of a pT3N1Mx non-functional G1 NET with SRS positive, non-resectable but stable, residual mass encasing mesenteric vessels. Serum cortisol (3261 nmol/L), ACTH (796 ng/L), CgA (530 pmol/L) and urine total cortisol metabolites (33920 µg/24h) including 14 sub-products indicated change of biological behaviour into a functioning NET. Pituitary or pulmonary sources were excluded

#556 Unresectable Mesenteric Midgut NETs: Are They a Unique Prognostic Category?
Introduction: Patients with lymph-node positive midgut NETs (stage IIIB) represent a heterogeneous group. While some have microscopic lymph node involvement on pathological evaluation, others may develop large, desmoplastic, unresectable tumors in the root of the mesentery.

#200 Genome-Wide MicroRNA Expression in Small Intestine Neuroendocrine Tumors (“Midgut carcinoids”): Upregulation of miRNA-182, miRNA-183 and Downregulation of miRNA-215
Introduction: MicroRNAs (miRs) may regulate cell proliferation, differentiation, apoptosis and function as tumor suppressors or oncogenes. MiR expression is not characterized in neuroendocrine midgut carcinoids.

#424 Role of MicroRNAs in Small Intestine Neuroendocrine Tumors
Introduction: Small intestinal neuroendocrine tumors (SI-NETs) arise from enterochromaffin cells, which belong to the endocrine system. MicroRNAs (miRs) are post-transcriptional regulators. They control multiple biological processes often functioning either as tumor suppressor genes or oncogenes.

#583 Olfactory Receptor 51E1 is a Potential Novel Tissue Biomarker for the Diagnosis and Prognosis of Small Intestine Neuroendocrine Tumors
Introduction: Small intestine neuroendocrine tumor (SI-NET) patients get late diagnosis. We reported olfactory receptor 51E1 (OR51E1) as a SI-NET-mRNA marker.

#1274 Carcinoid Tumors Presenting as Appendicitis
Introduction: Many conditions related to appendix present as appendicitis. These conditions can range from fecolith obstruction to tumors .Carcinoid tumors are most common tumors to present in appendix. Most of the carcinoid tumors in appendix present as appendicitis. Majority of the cases are diagnosed after histopathological examination. Tumors with the size of 2cm are treated with right hemicolectomy.

#2831 Immunohistochemical Profile of Digestive Neuroendocrine Neoplasms: A Retrospective Analysis in a Single Algerian Institution
Introduction: Neuroendocrine Noplasms (NEN) are rare tumours, but their incidence is clearly increasing in our country due to the improvement of diagnostic means, in particular the generalization of immunohistochemical techniques. The digestive location represents more than 70% of the cases. The anatomopathological study enables to classify the NEN in different prognostic grades according to the degree of differentiation, mitotic index and Ki67.

#2995 Prediction of Symptomatic Mesenteric Mass in Patients with Small Intestinal Neuroendocrine Tumors Using a CT Radiomics Approach
Introduction: A mesenteric mass surrounded by fibrosis is a hallmark feature of small intestinal neuroendocrine tumors (SI-NETs) that can induce severe abdominal complications. To improve clinical outcome, there is a need for personalized treatment strategies based on accurate prediction of development of abdominal complications.
