#3016 DLL3 Is Expressed in GEP-Neuroendocrine Neoplasms with Loss of RB1 and Has Prognostic Significance

Introduction: The negative notch regulator DLL3 has gained increasing attention in tumors with neuroendocrine features, in particular SCLC, LCNEC and neuroendocrine prostate cancer, both as prognostic marker and candidate therapeutic target. No data are available on the expression of DLL3 in gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs).

#2981 The Distance from Pathology to Molecular Imaging: SSTR Expression Comparison in 100 Gastroenteropancreatic Neuroendocrine Neoplasms

Introduction: Somatostatin receptor (SSTR) overexpression is a unique feature of gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs), which establish the basis for both diagnosis and therapy. SSTR status can be evaluated by immunohistochemical staining (IHC) and 68Ga-DOTATATE PET/CT.

#2936 Mutational Landscape of 109 High-Grade Gastroenteropancreatic Neuroendocrine Neoplasms G3

Introduction: Gastroenteropancreatic (GEP) neuroendocrine neoplasms (NEN) G3 are rare with a poor outcome. Molecular data for GEP NEN G3 is limited and the 2019 WHO classification is based on morphology and proliferation rate.
