#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.

#2855 Whole Exome Sequencing Reveals the Monoclonal Origin of Gastric Mixed Adenoneuroendocrine Carcinomas

Introduction: Gastric mixed adenoneuroendocrine carcinomas (g-MANECs) are rare neoplasms consisting of adenocarcinoma and neuroendocrine neoplastic components. G-MANECs show more malignant characteristics than gastric adenocarcinomas, while molecular mechanisms underlying the co-existence of the two components remains unknown.

#2257 Poorly Differentiated Neuroendocrine Carcinomas of the Colon: A Clinicopathological Study

Introduction: Neuroendocrine carcinomas (NEC) of the colon and rectum are aggressive and rare tumours. The Digestive Tract WHO classification 2010 defines the entity of large cell NEC (LCNEC) in contrast to small cell NEC (SCNEC).

#2250 Treatment Outcomes of Patients with Mixed Neuroendocrine Non-Neuroendocrine Neoplasms (MiNEN)

Introduction: Mixed neuroendocrine non-neuroendocrine neoplasms (MiNEN) have been newly defined in the WHO 2017 classification. They are rare tumors, commonly treated in analogy to their non-neuroendocrine (nNE) or neuroendocrine (NE) component without systematic data regarding the optimal therapeutic strategy.
