#2986 Characterization of 142 Human Pancreatic Neuroendocrine Tumors: ATRX and DAXX Correlation with Clinical-Pathological Data

Introduction: Pancreatic neuroendocrine tumors (PNETs) are rare and heterogeneous neoplasms with a 10-year survival rate less than 30%. Up to 43% of them are driven by inactivating mutations in ATRX or DAXX. These are important players at chromatin remodeling, that when mutated prone cancer cells to initiate the alternative lengthening of telomeres (ALT). ALT phenotype correlates with in situ loss of expression of the proteins ATRX or DAXX and can be corroborated by telomere-FISH.
