#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.

#886 Expression Patterns of Cellular Retinoic Acid Binding Protein-I in Neuroendocrine Tumors of the Lung: A Pilot Immunohistochemical Study
Introduction: Cellular retinoic acid binding protein-I (CRABP-I), a member of the lipid-binding proteins family, plays an important role in retinoic acid-mediated cell proliferation and is essential for the development of various malignant neoplasms. The actual role of CRABP-I in tumor progression remains unknown.

#1129 Expression and Clinical Significance of Merkel Cell Polyomavirus Large T Antigen in Merkel Cell Carcinoma
Introduction: Merkel cell carcinoma (MCC) is a rare and aggressive neuroendocrine skin cancer that is often associated with Merkel cell polyomavirus (MCPyV) infection. MCPyV expression and its relationship with clinical features and prognosis in MCC remain unclear.

#1307 Expression of m-TOR Pathway Components in Gastric Neuroendocrine Neoplasms: A Pilot Study
Introduction: The mammalian target of rapamycin (mTOR) signaling pathway plays a key role in the regulation of cell proliferation, protein synthesis and neuroendocrine tumor growth.

#1337 O6-Methylguanine DNA Methyltransferase (MGMT) Deficiency and Response to Aranoza-Based Therapy in Patients with Neuroendocrine Tumors
Introduction: Aranoza (3-α-L-arabinopyranosyl-1-methyl-nitrosourea) – nitrosourea derivative, as STZ. O6-methylguanine DNA methyltransferase (MGMT) is an enzyme implicated in chemotherapy resistance to alkylating agents and its low levels are associated with sensitivity to them.

#1653 Expression and Clinical Significance of Somatostatin Receptor Subtype 2A in Small Cell Lung Carcinoma
Introduction: Somatostatin receptors (SSTRs) play a key role in the regulation of cell proliferation and have been identified in a proportion of aggressive poorly differentiated neuroendocrine neoplasms, including small cell lung carcinomas (SCLCs).

#1939 Antiproliferative Effects of Lanreotide in Neuroendocrine Tumors
Introduction: Neuroendocrine tumors of the lung (BP-NETs, typical (AC) and atypical Carcinoids (ATC)) are rare tumors with heterogeneous behavior and molecular characteristics. For the intermediate proliferating BP-NETs treatment options are limited and unsatisfactory. Somatostatin analogues have not only anti-secretory effects, but also display antiproliferative features, as shown by PROMID and CLARINET trial. Nevertheless, their value in BP-NET is undefined so far.

#2133 Clinicopathological Features of the High Grade Pancreatic Neuroendocrine Neoplasms
Introduction: The high grade pancreatic neuroendocrine neoplasms (PanNENs) include well-differentiated tumors (WD-NETs) with elevated proliferation and poorly differentiated carcinomas (PD-NECs).

#2154 Clinical and Morphological Features of Extrapulmonary Small-Cell Cancer
Introduction: Extrapulmonary Small-cell cancer (ESCC) is an extremely rare disease. Usually in the treatment of patients with ESCC approaches to the treatment of patients with small cell lung cancer (SCLC) are used.
