#87 Alterations of E-cadherin, beta-catenin and caveolin-1 expression in gastroenteropancreatic neuroendocrine tumors
Introduction: Gastroenteropancreatic neuroendocrine tumors (GEP NETs) comprise a heterogeneous group of neoplasm with different histological patterns and biological behavior. Only limited information is available on immunohistochemical prognostic factors of disease. Alterations in the cell-cell adhesion system are closely associated with cell invasion and metastasis in many malignancies, including those of endocrine origin. Abnormal expression of E-cadherin and beta-catenin has been reported to play an important role in these processes. Caveolin-1 has recently been identified as a tumor metastasis modifier factor, which might increase the cell metastasis potential through the interaction with E-cadherin. However, the role of caveolin-1 in GEP NETs cell invasion remains unknown.

#1873 Meta-Analysis of Liver Resection versus Nonsurgical Treatments for Pancreatic Neuroendocrine Tumors with Liver Metastases
Introduction: Available data comparing the efficacy of different treatment regiments are rarely found. No meta-analyses have compared live resection with other nonsurgical treatments in resectable liver metastases from pNETs.

#1674 Meta-Analysis of Recurrence after Curative Surgery of Pancreatic Neuroendocrine Tumors.
Introduction: Follow-up after curative surgery for pancreatic neuroendocrine tumors (pNET) is designed to detect recurrence, however reliable recurrence rates are difficult to deduct from literature. Without this knowledge, appropriate follow-up regimens and indications for adjuvant treatment remain unclear.

#2086 miRNA Expression Defines Novel Subgroups of Small Intestinal Neuroendocrine Tumors
Introduction: Epigenetic dysregulation frequently occurs in cancers. Here we present the largest survival related miRNA profiling study to date of small intestinal neuroendocrine tumors (SI-NETs).

#484 Diagnostic Accuracy of Gallium-68 Somatostatin Receptor Positron Emission Tomography in Patients with Thoracic and Gastroenteropancreatic Neuroendocrine Tumors: A Meta-Analysis
Introduction: Gallium-68 somatostatin receptor (SMSR) positron emission tomography (PET) is a valuable diagnostic tool for patients with neuroendocrine tumors (NET). To date, a meta-analysis about the diagnostic accuracy of this functional imaging method is lacking.

#300 Association Between Time to Disease Progression Endpoints and Overall Survival in Patients with Neuroendocrine Tumors
Introduction: While the association between time to disease progression (TDP) and overall survival (OS) has been examined in a variety of cancers, it has not been assessed in trials of neuroendocrine tumors (NETs).

#619 Diagnostic Accuracy of F-18-DOPA PET or PET/CT in Neuroendocrine Tumors: A Meta-Analysis
Introduction: A specific feature of NETs is amine precursor uptake and decarboxylation; this is the rationale for using PET with F-18-DOPA, a cathecholamine precursor, in diagnosis of NETs.

#1089 Role of TGF beta-1 in Regulating Pancreatic Neuroendocrine Tumor Cell Viability
Introduction: Neuroendocrine tumors (NETs) are heterogeneous neoplasms arising from neuroendocrine cells spread in the respiratory and gastro-entero-pancreatic epithelium. The role of transforming growth factor beta-1 (TGF b-1) in NET biology is largely unknown. TGF b-1 signaling pathway is tumor suppressive in most non-transformed epithelial cell lines. In contrast, many human carcinomas are refractory to the growth–inhibitory effects of TGF b-1.

#1140 Incremental Benefit of Preoperative Endoscopic Ultrasound for the Detection of Pancreatic Neuroendocrine Tumors: A Meta-Analysis
Introduction: Current guidelines recommend computed tomography (CT) scan or magnetic resonance imaging as the initial imaging modalities for the work-up of suspected pancreatic neuroendocrine tumors (PNETs).
