#20 Paraneoplastic antigen Ma2 (PNMA2) auto-antibodies as biomarkers for early small intestine neuroendocrine tumors detection
Introduction: Small intestine neuroendocrine tumors (NETs) comprise well-differentiated NET (benign carcinoid), well-differentiated neuroendocrine carcinoma (malignant carcinoid) and poorly differentiated neuroendocrine carcinoma (NEC). The majority of NET patients have developed liver metastases at the time of diagnosis and surgery is then seldom curative. Novel predictive, diagnostic and prognostic markers are thus needed to improve our capabilities to diagnose and cure these tumors. We have previously identified six novel marker genes for neuroendocrine tumor cells by using Affymetrix microarrays and advanced bioinformatics. One of this markers, the paraneoplastic antigen Ma2 (PNMA2), which is normally expressed only in nervous tissue, can in the process of carcinogenesis be detected in tumors located outside the nervous system. The finding that Ma2 is expressed in small intestine neuroendocrine primary tumors and their metastases made it interesting to screen whether antibodies against Ma2 are present in the serum of NET patients.

#27 Combined treatment of rapidly progressing neuroendocrine tumors by transcatheter arterial chemoembolisation of the liver and peptide-receptor radiotherapy is save and effective. Report of thirty consecutive patients
Introduction: Patients with rapidly progressing neuroendocrine tumors presenting with high tumor load and/or severe clinical syndromes are clinically challenging and with limited life expectany. Peptide receptor radiotherapy (PRRT) and transcatheter arterial chemoembolization (TACE) have demonstrated efficacy in the treatment of neuroendocrine tumors. However, there are no reports that both therapies have been applied in combination.

#131 Efficacy and safety results from a Phase II study of pasireotide (SOM230) in the treatment of patients with metastatic NETs refractory or resistant to octreotide LAR
Introduction: Pasireotide, a multi-receptor targeted somatostatin analogue, has 30-, 5- and 39-fold greater affinity for sst1,3 and sst5 receptors, respectively, and a slightly lower affinity for sst2, than octreotide. Because of this multi-receptor binding profile, pasireotide may be effective in controlling symptoms of carcinoid syndrome in patients with gastroenteropancreatic neuroendocrine tumors (NETs) who are no longer responsive to currently available somatostatin analogues.

#151 Rationale for combining mTOR with other targeted agents in the treatment of neuroendocrine tumors
Introduction: Advanced neuroendocrine tumors (NETs) are aggressive and incurable with standard treatment. Many cellular targets are being evaluated in this patient population, including mammalian target of rapamycin (mTOR), a kinase that is the central regulator of several signaling pathways related to cell growth, angiogenesis, and bioenergetics. Because mTOR serves as a neoplastic switch activated by many cancer-related mutations, mTOR inhibition may have broad efficacy across tumor types, including NETs. Somatostatin analogs (SSAs) have long been used to treat carcinoid symptoms in NET patients. The SSA octreotide long-acting release (LAR) demonstrated significant antitumor effects against advanced midgut NETs in the phase III PROMID study.

#178 Treatment with 177Lutetium-DOTA-Tyr3-octreotate in Patients with Neuroendocrine Tumors
Introduction: Neuroendocrine tumors express somatostatin receptors. Treatment with radiolabelled somatostatin analogs has been used for more than 10 years. Useful isotopes are 111Indium, 99Yttrium and 177Lutetium.

#193 Paraneoplastic Antigen Ma2 Autoantibodies as Specific Blood Biomarkers for Detection of Early Recurrence of Small Intestine Neuroendocrine Tumors
Introduction: Small intestine neuroendocrine tumors (SI-NETs) are rare fatal cancers. Many patients develop metastatis before diagnosis. There is no available curative treatment for patients with metastasis.

#198 Novel Insights in Octreotide Effects on Human Neuroendocrine Cell Line CNDT2.5
Introduction: Octreotide, the first synthetic somatostatin analog available for clinical use, efficiently binds somatostatin receptors (SSRs) 2 and 5 and may transduce its effects by using SSRs.

#200 Genome-Wide MicroRNA Expression in Small Intestine Neuroendocrine Tumors (“Midgut carcinoids”): Upregulation of miRNA-182, miRNA-183 and Downregulation of miRNA-215
Introduction: MicroRNAs (miRs) may regulate cell proliferation, differentiation, apoptosis and function as tumor suppressors or oncogenes. MiR expression is not characterized in neuroendocrine midgut carcinoids.

#213 Distinct Cut-Off Values of Ki-67-index for NET-Grading in a Large German Multicentrer Cohort
Introduction: Grading (G) of neuroendocrine tumors (NET) according to ENETS is based on immunhistochemical staining of Ki-67 antigen. Close margins between G1 and G2 NET often fail to differ in survival analysis.

#214 Comparison of the AJCC and ENETS Staging Classifications for Neuroendocrine Tumors of the Pancreas
Introduction: The AJCC Cancer Staging Manual (7th edition, 2010) has introduced a novel TNM staging classification for pancreatic NETs. This classification has not yet been validated.
