#180 Microvessel Density and Prognosis of Gastroenteropancreatic Neuroendocrine Tumors (GEP-NETS)
Introduction: The role of anti-angiogenic agents in GEP-NETS remains to be established. CD105 (Endoglin) identifies the TGF-ß1 receptor which is expressed on endothelial cells involved in tumor angiogenesis.

#37 Gastric GIST with synchronous neuroendocrine tumor of the pancreas, Case Report and Literature Review
Introduction: The Gastrointestinal Stromal Tumors (GIST) are the most common mesenchymal tumors of the gastrointestinal tract. These are rare tumors with an incidence of 15 new cases per million per year. They often occur in individuals over the age of 40 years, without gender predominance. The clinical behavior is variable and benign tumors are the most common. They can develop anywhere in the GI tract, but are more frequent in the stomach and small intestine. The primary treatment, when located, is the surgical resection, which can be complemented with the use of imatinib.
The occurrence of neuroendocrine tumors of the pancreas is rare, representing 1-5% of pancreatic cancers, and it is estimated that its incidence does not exceed 5 to one million. The tumors considered nonfunctioning (15-32% of pancreatic neuroendocrine tumors) are not associated with any syndrome, and are usually incidental. They have a slight predominance in males, and are more frequent in the 6th decade of life. Nonfunctioning tumors of islet cells are virtually all malignant tumors, and the treatment consists of surgical resection.

#362 Succinate Dehydrogenase (SDH) Complex Expression in Pancreatic Endocrine Tumours (PETs)
Introduction: Absence of SDH subunit D (SDHD) mutations were reported by Perren et al (Oncogene 2002) but loss of heterozigosity (LOH) was described in 29% of the PETs. Since SDHD gene may depict a form of genomic imprinting in neuroendocrine (NE) tissue, the reported LOH may drive activation of the hypoxia pathway. Taking advantage from the immunohistochemical (IHC) method for genetic triage we may deduce the mutational status of SDH subunits (A, B, C and D) based on IHC SDHB expression. These subunits are striking candidates as they are mutated in other NE neoplasias.

#469 Cost-Effectiveness of Sunitinib in Patients with Advanced or Metastatic Pancreatic Neuroendocrine Tumors in Portugal
Introduction: Sunitinib is an oral multitargeted tyrosine kinase inhibitor approved in Europe in 2010 for use in well-differentiated pancreatic neuroendocrine tumors (pNET) that have spread or cannot be removed by surgery.

#782 Appendix Well-Differentiated Neuroendocrine Tumors (A-WDNETs) at a Large Tertiary Center: Clinical-Pathological Features and Long-Term Follow-Up Evaluation
Introduction: A-WDNETs comprise 32-57% of appendix tumors, diagnosed incidentally in 0.3-0.9% appendectomies (AP). Overall survival is good, but malignant behavior remains controversial.

#1544 Immunohistochemical Expression of Estrogen and Progesterone Receptors in Neuroendocrine Tumors
Introduction: Expression of progesterone (PR) and estrogen receptor (ER) in some neuroendocrine tumors (NET) raises the possibility of hormonal regulation in these tumors, but those prevalence and clinical implication are unknown.

#2159 Hepatic Steatosis Secondary to Peptide Receptor Radionuclide Therapy with Somatostatin Analogue
Introduction: Peptide Receptor Radionuclide Therapy (PRRT) with 177-Lutetium-DOTA-TATE is a therapeutic modality for neuroendocrine tumors. It has some well known side effects, concerning specially the bone marrow (from cytopenias to myelodysplastic syndrome), in addition to mild renal effects. Hepatotoxicity from PRRT is still being studied.

#2161 Outcomes of Locoregional Treatment for Unifocal Progression in Widespread Metastatic Gastroenteropancreatic Neuroendocrine Tumors
Introduction: New systemic treatments have improved the therapeutic landscape for patients with progressive, metastatic GEP-NETs. While drugs such as everolimus are appropriate for patients with widespread disease progression, local treatment approaches may be more appropriate for patients with unifocal progression.

#144 Oxaliplatin-based chemotherapy in patients with advanced neuroendocrine carcinoma: an Italian retrospective multicenter analysis
Introduction: Conventional chemotherapy does not have a well-defined role in well/moderately differentiated (WD) neuroendocrine carcinomas (NECs). Various regimens were evaluated. Cisplatin or carboplatin combined with etoposide are usually indicated in poorly differentiated (PD) NECs. Some evidence exists for oxaliplatin activity in WD and PD NECs, combined with capecitabine or gemcitabine.
