#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.

#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).

#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.

#508 Differential Expression of Markers in a Midgut Carcinoid Tissue Microarray
Introduction: Molecular mechanisms driving well-differentiated midgut carcinoid (MGC) tumors are not well-established. To pursue higher resolution tumor diagnostics, we studied a panel of markers for their expression in MGC, including: serotonin, FGF2, b-catenin, and E-cadherin, in primary, lymph node, and liver metastases.

#2272 Enhancing Diagnostic Precision Through Combined Genomic and Histopathological Analysis of Pancreatic Neuroendocrine Tumors
Introduction: Diagnostic differentiation of uncommon pancreatic malignancies can be challenging, but is essential for accurate clinical management; genomic analysis may provide a tool for making this critical distinction.

#986 Expression of the Truncated Somatostatin Receptor Variant Sstr5TMD4 in Medullary Thyroid Carcinoma
Introduction: Medullary thyroid carcinoma (MTC) is a rare tumor originating from thyroid parafollicular C cell. The only available treatment is surgical resection, which is not always feasible. Somatostatin and its receptors are expressed both in normal human thyroid C cells and in MTC, but their role has not been fully elucidated. The discovery of a truncated isoform of Sstr5, Sstr5TMD4, associated with increased invasiveness and aggressiveness in breast cancer, has opened new insight in the role of Sstr in cancers.
