#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.

#100 Mammalian target of rapamycin (mTOR) expression analysis and therapeutic approach in lung and gastroenteropancreatic poorly differentiated endocrine carcinoma (PDEC)
Introduction: PDEC clinically include gastroenteropancreatic PDEC, small cell lung cancer (SCLC) and large cell neuroendocrine carcinoma (LCNEC). These tumors are clinically similar and aggressive and they are usually treated with platinum compounds. mTOR signalling pathway has emerged as a promising target for well-differentiated endocrine carcinoma therapy. Because of varying behavior, PDEC are usually excluded from clinical trials employing the mTOR inhibitor RAD001.

#117 Synchronous appendiceal neuroendocrine carcinoma and mucinous cystadenocarcinoma: a case report
Introduction: Appendiceal tumors with histological features of both carcinoids and adenocarcinomas are very rare. Carcinomas of the appendix are usually mucinous adenocarcinomas with a tendency to produce peritoneal pseudomyxoma and without metastatic spread until late in the disease course. Carcinoid tumors of the appendix are a common incidental finding.

#141 Incidence of second primary tumors in patients with neuroendocrine tumors
Introduction: Based on epidemiological data from SEER 1950-1999, 22.4% cases of non-carcinoid second primary tumors have been described in patients diagnosed with neuroendocrine tumors. The incidence of this type of tumors varies, depending on the series assessed.

#182 Ki-67 (MIB-1) Proliferative Activity and Beta-Catenin Immunoexpression in Liver Metastases of Gastroenteropancreatic Neuroendocrine Tumors
Introduction: Assessment of liver metastases biology features associated with cell proliferation and adhesion has a strong prognostic impact in patients with gastroenteropancreatic (GEP) neuroendocrine carcinomas.

#237 Clinical Case of ACTH-secreting Thymic Carcinoma with Multiple Metastases to the Brain, Ovary and Skin
Introduction: ACTH-secreting thymic carcinoma (TC) is a rare neuroendocrine tumor which has a very aggressive course. We present a case of ACTH-producing TC in a 36-year-old woman.

#268 Temozolomide as 2.-3. line Treatment of Patients with Poorly Differentiated Neuroendocrine Carcinomas
Introduction: Knowledge of the clinical efficacy of treatment beyond first line of poorly differentiated neuroendocrine carcinomas (PDEC) is sparse. Temozolomide (TMZ) has shown effect in well-differentiated NET.

#311 Treatment and Prognosis of Patients with Poorly Differentiated Neuroendocrine Tumors
Introduction: Poorly differentiated neuroendocrine tumors (PDEC) represent less than 10% of all neuroendocrine tumors but have a poor prognosis.

#314 Clinical Effect of Temozolomide-Based Chemotherapy in Poorly Differentiated Endocrine Carcinoma (PDEC) after Progression on First-Line Chemotherapy
Introduction: Patients with metastatic PDEC usually have a short survival. After first-line palliative chemotherapy, there are no established second-line treatments. Temozolomide has shown effect in other NETs.
