#174 Loss of Expression of the DNA Mismatch Repair Proteins MLH1 and MSH2 is Rare in Pancreatic and Small Intestinal Neuroendocrine Tumors
Introduction: Loss of expression of the DNA mismatch repair (MMR) proteins MLH1 and MSH2, which is known to correlate strongly with MSI, has not been well studied in pancreatic or small intestinal NETs.

#1845 Mismatch Repair (MMR) Protein Expression is Uncommon in Poorly Differentiated Neuroendocrine Carcinoma
Introduction: Microsatellite instability (MSI) has been reported to occur in a significant proportion of neuroendocrine carcinoma (NEC) and mixed adenoneuroendocrine carcinomas (MANEC) (11 out of 89 cases, Sahnane et al, ERC 2015). It might be predictive of response to immunotherapy.

#2123 Large Cell Neuroendocrine Carcinoma (LCNEC) Associated with a Dysplastic Sessile Serrated Lesion (SSL) and Deficient Mismatch Repair (MMR) Protein: A Case Report.
Introduction: Colorectal poorly differentiated neuroendocrine carcinomas (NECs) are rare, but extremely aggressive. The mechanisms of their carcinogenesis and aggressiveness are still largely unknown. Recently Nobuyoshi Takizawa showed that the molecular features of colorectal NECs are similar to those of adenocarcinoma and not to those of NETs and they were more evident in small cell NECs than in large cell NECs. This is supported by combined cases with conventional adenoma/adenocarcinoma and NECs. Stelow et al showed that DNA mismatch repair proteins were intact in 14/15 colorectal small cell NECs. Two cases of LCNECs arising from SSL have been reported so far in the literature.

#122 Molecular genetic findings in gastric carcinoid suggest possible neurofibromin/Ras pathway involvement in carcinoid pathogenesis
Introduction: The molecular pathogenesis of gastrointestinal carcinoid tumours is poorly understood. We have been undertaking molecular genetic investigations of a young woman with neurofibromatosis type 1 (NF1) in whom a gastric carcinoid tumor was detected following an episode of gastrointestinal bleeding. She was otherwise relatively mildly affected by NF1. In NF1, gastric carcinoids have been found previously only in patients with other predisposing factors, which were absent in this patient.

#265 A Novel PKCßII Inhibitor Induces Antiproliferative Effects in Human Pancreatic Neuroendocrine Tumor Cells
Introduction: Deregulation of the protein kinase C (PKC) signaling pathway has been implicated in tumor progression.

#266 Everolimus Reduces Cell Viability in Selected Human Medullary Thyroid Carcinoma Primary Cultures
Introduction: It has been demonstrated that everolimus, an mTOR inhibitor, has a potent anti-proliferative effect in a human Medullary Thyroid Carcinoma (MTC) cell line, TT, and in two human MTC primary cultures.

#429 Bronchial Carcinoid Response to mTOR Inhibitors Depends on mTOR Expression Levels
Introduction: Bronchial carcinoids (BCs), originating from endocrine cells dispersed in the respiratory epithelium, can be divided into typical (TBC) and atypical (ABC). TBC are less aggressive, smaller, and much less likely to metastasize, while ABC are more aggressive and metastasize. mTOR has a central role in regulating cell growth, metabolism, and apoptosis. A differential mTOR activation in BCs has been previously demonstrated, suggesting that mTOR pathway might play a predictive role in patients eligible for mTOR-targeted therapies

#430 mTOR Inhibitors Hamper Cell Viability in Selected Human Medullary Thyroid Carcinoma Primary Cultures
Introduction: It has been demonstrated that mTOR inhibitors have potent anti-proliferative effects in a human Medullary Thyroid Carcinoma (MTC) cell line. We here explore the possible role of mTOR inhibitors, Everolimus and BEZ235 (which also inhibits the PI3K pathway) on the effects of Insulin-like Growth Factor-1 (IGF-1) in human MTC primary cultures.

#479 Efficacy and Safety of Everolimus in Metastatic Gastroenteropancreatic Neuroendocrine Tumors
Introduction: Everolimus is a treatment option for patients with pancreatic NETs, while its use in patients with gastrointestinal NETs still remains to be defined.
