#1807 Adherence to WHO2010 Guideline for Diagnosis of Neuroendocrine Carcinoma and Prognostic Significance
Introduction: Neuroendocrine carcinoma’s (NEC) are diagnosed by a combination of immunohistochemistry (IHC) and morphology according to the 2010 WHO guidelines.

#1429 Evaluate the Accuracy of Pathological Diagnosis on Biopsy Specimens from Gastrointestinal Neuroendocrine Tumors
Introduction: Gastrointestinal neuroendocrine neoplasms (GI-NENs) is a highly heterogeneous tumor. The accuracy of pathological diagnosis on the biopsy is crucial for GI-NENs but rarely investigated

#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.

#2037 Stromal Immune Contexture Predicts Disease-Free Survival in Gastro-Entero-Pancreatic Neuroendocrine Neoplasms (GEP-NENs)
Introduction: Stromal Immune Contexture (SIC) helps predict prognosis in solid Tumors (T) but has been poorly investigated in gastro-entero-pancreatic neuroendocrine neoplasms (GEP-NENs). We tested whether GEP-NENs profiling for adaptive immunity-related SIC markers, as well as inflammatory (COX2),EMT [Beta-catenin (B-cat)] and oncogenic pathway signaling (pS6) markers,could improve Ki67 and/or MO-based prediction of OS and DFS.

#2188 Predictive Markers of Gastroenteropancreatic Neuroendocrine Tumors (GEP-NETS)
Introduction: NET are relatively rare and up to still far from fully studied pathology. The frequency of NET GEP does not exceed 2% of all tumors of this localization.

#1515 Pathomorphology of Sporadic Medullary Thyroid Carcinoma – A Retrospective Analysis for a Period of 10 Years
Introduction: Medullary thyroid carcinoma (MTC) is a rare neuroendocrine tumor, often difficult for diagnosis both clinically and histologically.

#50 Clinical-morphology correlation in diagnostics and evaluating surgery results of pancreatic insulinoma and nesidiobastosis
Introduction: Organic hyperinsulinism syndrome (OHS) is revealed in 85% cases of pancreas insulinoma. Nesidioblastosis (NB) induces OHS in 15% of the cases. Surgical cure provides all symptoms of insulinoma disappearing, while cytoreductive operation results in considerable improvement of life quality. There is no intraoperative opportunity to reveal insulinoma grade, even if an urgent biopsy is performed. Thus, it is essential to determine the cause of OHS and to apply the surgical cure method during the preoperational period, thereby improving the long-term prognosis.

#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.

#1368 Everolimus in Pancreatic Neuroendocrine Carcinomas G3
Introduction: Neuroendocrine Carcinomas (NEC) G3 are heterogeneous diseases with different behaviors, basing on tumor morphology and Ki67 value. Platinum-based chemotherapy is considered the standard treatment in these pts. However, tumors with well-moderately differentiated morphology (NET G3), with Ki67 < 55% may be considered a separate entity in terms of prognosis and therapeutic options

#1604 Resection of Liver Metastases in Patients with High-Grade Gastroenteropancreatic Neuroendocrine Carcinomas: A Nordic Multicenter Study
Introduction: Gastroenteropancreatic neuroendocrine carcinomas (GEP-NEC) are generally characterized by synchronous metastases, high aggressiveness and a dismal prognosis. Currently, resection of liver metastases in patients with metastatic GEP-NEC is not recommended. However, the existing data are scarce.
