#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.

#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.

#558 MANECs Among Colorectal Signet Ring Cell Carcinomas
Introduction: The mixed adenoneuroendocrine carcinomas (MANEC, WHO 2010) are neoplasms with heterogeneous morphology, whose mixed nature may be difficult to recognize.

#622 Evaluation of Mucin and Neuroendocrine Expression in Diffuse Gastric Cancer with Signet Ring Cell Morphology
Introduction: A proportion of diffuse gastric carcinoma, according to the Lauren classification system, has signet ring cell morphology. Signet ring cells are characterized by a peripherally placed nucleus and a central amorphous substance, which is reported to be mucin based on Periodic Acid Schiff positivity (PAS). PAS is not a specific staining method for mucin. Neuroendocrine expression has previously been reported in tumor cells in diffuse type gastric cancer.

#685 A Small Mixed Adenocarcinoma and Neuroendocrine Tumor of the Duodenum with Multiple Liver Metastases
Introduction: Mixed adenocarcinoma and neuroendocrine cancers (MANECs) are rare specific type of tumors that are composed of two histologic components: a neuroendocrine carcinoma and an adenocarcinoma. There are only a few reports regarding MANEC of the stomach, colon and rectum in the literature.

#715 Neuroendocrine Tumors of the Rectum: Experience in Argentina
Introduction: Neuroendocrine tumors (NETs) of the rectum have been increasing in incidence. They are approximately 18% the all NETs and 27% of all gastrointestinal NETs. Rectal NETs are usually small and are often found incidentally during endoscopy. Patients (pts) with local disease have a favorable prognosis of a 5-year survival rate of 88-91%. Optimal treatment of NETs of the rectum has been widely debated.

#867 Mixed Adenoneuroendocrine Carcinoma (MANECs): A Rare and Challenging Subgroup of Neuroendocrine Neoplasia
Introduction: Mixed Adenoneuroendocrine Carcinomas (MANECs) are rare entities in which at least 30% of neoplastic cells are neuroendocrine in nature (WHO 2010 classification). They result either from two independent lesions that merge together or are unique lesions with different cell populations intermingled.

#873 The Analysis of Immunohistochemistry Staining, Neuronspecific Enolase (NSE) Level and Somatostatin Receptor Scintigraphy of Gastroenteropancreatic Neuroendocrine Neoplasm Cases
Introduction: 99mTc-HYNIC-TYR3-OCTREOTIDE somatostatin receptor (SSR) scintigraphy has been used to diagnose gastroenteropancreatic neuroendocrine neoplasms (GEP-NEN).
