#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.

#2159 Hepatic Steatosis Secondary to Peptide Receptor Radionuclide Therapy with Somatostatin Analogue

Introduction: Peptide Receptor Radionuclide Therapy (PRRT) with 177-Lutetium-DOTA-TATE is a therapeutic modality for neuroendocrine tumors. It has some well known side effects, concerning specially the bone marrow (from cytopenias to myelodysplastic syndrome), in addition to mild renal effects. Hepatotoxicity from PRRT is still being studied.

#964 Ewing Sarcoma a Dangerous Pitfall for Poorly Differentiated Neuroendocrine Carcinoma (PDEC) in Ileum

Introduction: Ewing sarcoma (ES) primary to the ileum (IES) has rarely been documented, and shows close similarities in histology and clinical presentation with PDEC.EWSR1-FEV translocation is exceedingly rare in ES, as FEV expression is restricted to prostate, brain, and serotonin neuroendocrine cells (NE) and related tumors.

#942 Ileal Neuroendocrine Well-Differentiated Tumors: Prognostic factors with Focus on Loss of Succinate Dehydrogenase (SDHB) Expression

Introduction: Ileal Neuroendocrine Well-Differentiated Tumors (INWDT) are the most common neuroendocrine neoplasms in the gastrointestinal tract. Gene mutations of SDH complex drive pathogenesis of cancer cells through their role in angiogenesis and cell proliferation.
