#1377 Metastatic Neuro Endocrine Tumors: Epidemiological Characteristics, Management and Prognostics Factors. Results from an Inter-Regional Network in France between Upper and Lower Normandy

Introduction: Metastatic neuro-endocrine tumors (MNETs) are rare and their management are complex. To standardize therapeutic strategies in France, a national network of clinicians (RENATEN) has been created, composed of 17 expert centres.

#1312 Epigenetic Remodeling upon DAXX and ATRX Loss in Pancreatic Neuro-endocrine tumors (pNETs)

Introduction: DAXX and or ATRX loss occur in 40% of sporadic pNETs. DAXX and ATRX participate in the cell epigenetic status maintenance. Epigenetic changes influence gene expression, function of telomeres and genomic stability. We hypothesize that DAXX/ATRX loss drives tumor progression in pNET through epigenetic changes affecting genomic stability.

#1186 Significance of ATRX/DAXX Expression and Alternative Lengthening of Telomeres in Insulinomas and Neuroendocrine Tumors of Small Intestine.

Introduction: ATRX and DAXX mutations associated with alternative lengthening of telomeres ( ALT) phenotype have been shown as one of the major altered pathways in pancreatic neuroendocrine tumors (PanNET).
