#3751 Grade 2 gastric carcinoids type 1 – Not always an indolent disease

Introduction: Gastric carcinoids type 1 (GC1) are increasingly recognized and are usually well-differentiated grade 1 neoplasms. However, rare cases of metastatic spread and adverse prognosis have been described in the literature.

#3524 Correlation of loss of ATRX expression with scintigraphic imaging studies in pancreatic neuroendocrine neoplasms

Introduction: Somatic inactivating mutations of ATRX (α thalassemia/mental retardation syndrome X-linked) in pancreatic neoplasms (pNENs) are associated with aggressive phenotype and are considered an independent prognostic factor of poor overall survival.
