#56 Somatostatinreceptor scintigraphy with Tc-99m-tektrotyd in patients with neuroendocrine tumors: correlation with immunohistochemistry
Introduction: Somatostatin receptor scintigraphy (STRS) with Tc-99m-tektrotyd has been used in the past few years for diagnosis and staging of neuroendocrine tumors (NETs). A number of clinicopathologic criteria proved to be useful predictors of malignant behavior of these tumors. Immunohistochemical markers for NETs include cell proliferation (Ki-67 index) and neuroendocrine markers such as chromogranin A (CgA) and synaptophysin.

#1465 Assocation Between miRNAs and HDACs in Pancreatic Neuroendocrine Tumors
Introduction: Epigenetic factors are essentially involved in carcinogenesis, tumor promotion and chemo resistance with their major key players of miRNAs and histone deacetylases (HDACs). As shown by own theoretical databank analysis, the crosstalk between miRNAs and HDACs are relevant in different human chronic diseases and cancerogenic pathways.

#1484 Neuroendocrine Tumors of the Appendix Are Probably Harmless Neoplasms
Introduction: Appendiceal neuroendocrine tumors (aNETs) have a 5-year survival rate between 74% and 95% according to recent data from Cancer Registry of Norway and the United States, respectively. However, in the daily clinical practice one almost never encounters patients suffering from aNETs with distant metastasis or dying of the disease.

#1490 Even Malignant Appendiceal Neuroendocrine Tumors Exhibit No Recurrent Chromosomal Alterations
Introduction: Neuroendocrine tumors (NETs) of the midgut are located in the ileum (iNET), caecum or appendix (aNET). Despite of the similar origin, NETs of the ileum and the appendix behave remarkably different. iNETs show high malignant potential, which manifests with early lymph node or liver metastases. Genetically, the loss of chromosome 18 (Ch18) in 60-74% of cases is the most frequent alteration in iNETs. aNETs are often incidental findings, rarely show metastases, and no chromosomal alterations are known.
