#3014 The Number of Positive Nodes Accurately Predicts Recurrence after Distal Pancreatectomy for Nonfunctioning Neuroendocrine Neoplasms
Introduction: The most appropriate staging system of metastatic lymph nodes (N) for resected pancreatic neuroendocrine tumors (PanNETs) remains unclear, especially regarding those resected by distal pancreatectomy (DP).

#38 Expression of mTOR signaling pathway and effects of mTOR inhibitors on its pathway in human neuroendocrine tumors
Introduction: Neuroendocrine tumors (NET), especially well-differentiated endocrine tumors, are often slow-growing, indolent, and may not become clinically apparent until the manifestations of metastatic spread or carcinoid syndrome. Results of previous studies demonstrated that phosphoinositide 3-kinase (PI3K)/Akt/mTOR signaling pathway may be activated in the great majority of NET cells. mTOR inhibitors are therefore considered effective anti-tumor reagents but they may also induce an activation of PI3K/Akt and MAPK pathways as a compensatory action and reduce their own anti-tumor activities.

#556 Unresectable Mesenteric Midgut NETs: Are They a Unique Prognostic Category?
Introduction: Patients with lymph-node positive midgut NETs (stage IIIB) represent a heterogeneous group. While some have microscopic lymph node involvement on pathological evaluation, others may develop large, desmoplastic, unresectable tumors in the root of the mesentery.

#635 Neuroendocrine Tumors of the Gastrointestinal Tract with Second Primary Malignancy
Introduction: Neuroendocrine tumors of the gastrointestinal tract (NETs of GIT) are rare neoplasms frequently associated with synchronous or metachronous second primary malignancy (SPM). This phenomenon can be a result of an increasing incidence of NETs in patients who are examined for another primary malignancy. However, other theories suppose genetic predispositions or growth impact of different neuroendocrine peptides produced by NET.

#791 Quantification of Somatostatin Receptor Subtypes Using In Vivo PET/CT-Data, Ex Vivo Conventional Immunohistochemistry and Automated Digitized Analysis by Definiens XD Image Software
Introduction: Diagnostics and therapy of NET are significantly influenced by their somatostatin receptor (SSTR) status. Immunohistochemistry (IHC) of SSTR performed by pathologists is a time-consuming and cost-intensive procedure.

#801 Normal Gastrointestinal Neuroendocrine Cells Lack E-cadherin
Introduction: E-cadherin plays a crucial role in the adhesion between epithelial cells and thus epithelial integrity. Moreover, germ line mutations in the E-cadherin gene (CDH1) causing loss of E-cadherin function (adhesion) leads to hereditary gastric cancer of the diffuse type, according to Laurén. Even sporadic gastric carcinomas of the diffuse type often lose E-cadherin expression due to mutations. Lack of E-cadherin has been recorded at an early phase in such carcinomas.

#1375 Merkel Cell Carcinoma of the Knee Treated with Somatostatin Analogue and Radiotherapy: A Case Report
Introduction: Merkel cell carcinoma (MCC) is a rare and aggressive primary cutaneous neuroendocrine malignancy. Chemotherapy with cisplatin (CDDP) and etoposide (VP16) is an effective treatment for metastatic MCC.

#1432 Neutrophil-Lymphocyte Ratio Predicts Survival in Pancreatic Neuroendocrine Tumors
Introduction: Although the prognostic role of neutrophil-lymphocyte ratio (NLR) has been confirmed in a variety of tumors, the prognostic role of NLR in pancreatic neuroendocrine tumors (PNETs) has not been examined.
