#3067 Somatostatin Analogs in Real‐World Practice for Patients with Metastatic Neuroendocrine Tumors: A Single Institution Experience in the Ouest of Algeria (CHU Oran)
Introduction: The efficacy of somatostatin analogs (SSAs) were clearly established trough pivotal trials as first‐line agents for neuroendocrine tumors (NETs), but their use in clinical practice is largely unknown.

#2837 Development and Initial Validation of a Brief Questionnaire to Assess Patient Satisfaction with Self-Injection of Lanreotide Autogel: Results During a Home Training Programme
Introduction: The long acting formulation of lanreotide autogel(LAN) can facilitate self-injection (SI) by patients or caregivers at home, avoiding visits to health centers. Training by nurses is required to ensure successful SI. Patient satisfaction(PS) is an important outcome of SI and home care programs.

#2874 Role of FOXM1 in Aggressive Pancreatic / Pulmonary Neuroendocrine Carcinomas and Anti-Tumor Effect of the FOXM1 Inhibitor Thiostrepton
Introduction: DNA-targeting agents are the main treatment of aggressive pulmonary and pancreatic neuroendocrine carcinomas (NEC). FOXM1 is a transcription factor controlling cell proliferation and DNA repair pathways, playing therefore an important role in tumor progression and chemoresistance.

#2980 Metabolic Dysregulation and Circadian Clock in Cellular Models of Neuroendocrine Tumors
Introduction: The circadian clock genes encode transcription factors whose interaction with nuclear receptors allows the regulation of cellular metabolism.The invalidation of the genes of the clock core is associated with the development of many endocrine diseases including neuroendocrine cancer. Recently, the family of transcriptional coactivators PGC-1a has been identified as a key element in the integration of cellular metabolic state with the circadian clock. PRC, as a member of the PGC-1 family, was able to interact with several transcription factors, including the CLOCK factor. The specific induction of this PRC factor by the cell cycle, to modulate the energy function, the MAPkinase pathway and the expression of microRNAs, makes it a key factor in the metabolic adaptation of cancer cells.

#70 The validity of Ki-67 as a prognostic indicator in patients with appendiceal carcinoid tumor
Introduction: Carcinoid tumors of the appendix are rare and often discovered incidentally through appendectomy. Most are clinically benign but may be associated with metastatic disease. Ki-67, a nuclear protein structurally associated with chromatin, is an excellent marker for measuring cell proliferation and it has been shown to correlate with the outcome in pancreatic and ileocecal carcinoids.

#87 Alterations of E-cadherin, beta-catenin and caveolin-1 expression in gastroenteropancreatic neuroendocrine tumors
Introduction: Gastroenteropancreatic neuroendocrine tumors (GEP NETs) comprise a heterogeneous group of neoplasm with different histological patterns and biological behavior. Only limited information is available on immunohistochemical prognostic factors of disease. Alterations in the cell-cell adhesion system are closely associated with cell invasion and metastasis in many malignancies, including those of endocrine origin. Abnormal expression of E-cadherin and beta-catenin has been reported to play an important role in these processes. Caveolin-1 has recently been identified as a tumor metastasis modifier factor, which might increase the cell metastasis potential through the interaction with E-cadherin. However, the role of caveolin-1 in GEP NETs cell invasion remains unknown.

#106 Gastroenteropancreatic neuroendocrine tumors: single institution clinicopathological study
Introduction: Neuroendocrine cells are widely distributed throughout the body, and neoplasms from these dispersed cells can arise at many sites. They are distinguished into two broad categories: 1) Tumors identified as small cell lung carcinomas with biology and natural history of a high-grade malignancy and characteristics of small cell undifferentiated or anaplastic appearance by light microscopy. The WHO categorizes these tumors as poorly-differentiated neuroendocrine carcinomas; 2) Well-defined neuroendocrine tumors (NETs) with variable, but most lyindolent biologic behavior and characteristic well-differentiated histologic features. The majority arise in the gastrointestinal tract and collectively they are referred as gastroenteropancreatic neuroendocrine tumors (GEP/NETs). They include carcinoid tumors, pancreatic islet cell tumors (gastrinoma, insulinoma, glucagonoma, VIPoma, somatostatinoma), paragangliomas, pheochromocytomas, and medullary thyroid carcinomas. The WHO classifies the GEP/NETs as well-differentiated NETs (carcinoid tumors) if they are noninvasive and have benign behavior or uncertain malignant potential. In contrast, GEP/NETs with characteristics of low-grade malignancy with invasion of the muscularis propria or beyond, or metastases, are characterized as well-differentiated neuroendocrine carcinomas (malignant carcinoids). Pancreatic islet cell tumors, whether functioning or not, are classified as well-differentiated NETs or well-differentiated neuroendocrine carcinomas, due to the (depending on) histologic characteristics. The WHO classification for gastroenteropancreatic NETs based on stage (ie size and presence of metastases) and grade (mitotic rate, perineural and lymphovascular invasion, Ki-67 proliferative index) categorizes them as well-differentiated NETs, e.g., carcinoid tumors, or as well-differentiated neuroendocrine carcinomas.

#114 Downstaging of a gastroenteropancreatic neuroendocrine tumor after combination therapy of temozolomide, Bevacizumab and long-acting somatostatin analogs
Introduction: Patients with gastroenteropancreatic endocrine (GEP) tumors and progressive disease have been treated with several chemotherapeutic regimens with variable responses and considerable toxicity. Recent studies have shown that GEP tumors may respond to therapy with anti-angiogenic agents, mainly as a result of their increased vascularity.

#120 Somatostatin receptors 1-5 expression in a large series of well-differentiated neuroendocrine tumors
Introduction: For their antisecretive and antiproliferative effect somatostatin analogs (SA) have been used in the treatment of neuroendocrine tumors (NETs), based on the expression of somatostatin receptors (sstRs). The potential availability of new SA for the treatment of patients with NETs suggests a better characterization of sstRs.
