#2986 Characterization of 142 Human Pancreatic Neuroendocrine Tumors: ATRX and DAXX Correlation with Clinical-Pathological Data
Introduction: Pancreatic neuroendocrine tumors (PNETs) are rare and heterogeneous neoplasms with a 10-year survival rate less than 30%. Up to 43% of them are driven by inactivating mutations in ATRX or DAXX. These are important players at chromatin remodeling, that when mutated prone cancer cells to initiate the alternative lengthening of telomeres (ALT). ALT phenotype correlates with in situ loss of expression of the proteins ATRX or DAXX and can be corroborated by telomere-FISH.

#3013 Structurally-Optimized Peptide VMT-Alpha-NET Enhances the Efficacy of SSTR2-Targeted Alpha-Particle Therapy for Neuroendocrine Tumors
Introduction: 203Pb/212Pb is a promising theranostics pair for SSTR2-targeted alpha-particle therapy for neuroendocrine tumors (NETs). The development of SSTR2-targeted peptides that are optimized for the Pb isotopes has the potential to improve performance.

#101 Chronic Complications of Peptide Receptor Radionuclide Therapy (PRRT)- A Single Center Experience
Introduction: In the last decade, a new treatment modality, peptide receptor radionuclide therapy (PPRT), has been introduced for gastroenteropancreatic neuroendocrine tumor (GEPNET) patients with non-resectable or progressive disease. PRRT has been associated with several complications, including bone marrow suppression, renal toxicity and hepatic damage.

#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.

#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.

#271 A Novel Missense Mutation of the TMEM127 Gene that Leads to Pheochromocytoma Phenotype
Introduction: Recently, truncating germline mutations in TMEM127 gene have been identified in 30% of familial cases of adrenal pheochromocytoma (PHEO) and in 3% of apparently sporadic cases.

#358 Enhanced Combined 177Lu-DOTATATE and 90Y-DOTATATE Treatment of Patients with Metastatic Neuroendocrine Tumors Refractory to Conventional Therapy: An Ongoing Study.
Introduction: Neuroendocrine tumors (NETs) over-express somatostatin receptors (SRs) and the efficacy of peptide receptor radionuclide therapy (PRRT) with somatostatin analogues labeled with high activities of ß-emitting radioisotopes have been reported.

#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.

#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.
