#2765 Role of Biomarkers in Disease Progression of NET
Introduction: Due to the non specific features of neuroendocrine tumors and lack of diagnostic biomarkers, the diagnosis is usually delayed and almost half of patients presenting with distant metastases

#2890 Evaluation of Toxicity in Peptide Receptor Radionuclide Therapy (PRRT) for Neuroendocrine Tumors (NET)
Introduction: Peptide receptor radionuclide therapy (PRRT) is an encouraging systemic treatment for neuroendocrine tumors (NET). PRRT is generally safe and possesses little side effects but little is known about liver toxicity.

#2894 Single Institution Experience with Peptide Receptor Radionuclide Therapy (PRRT) in Neuroendocrine Tumors (NET)
Introduction: Neuroendocrine tumors (NETs) are a rare and heterogenous group of tumors with rising incidence. Peptide receptor radionuclide therapy (PRRT) with radiolabeled somatostatin analogue is an encouraging systemic treatment modality with minimum side effects.

#3071 Hormonal Ectopic Secretion Syndromes Associated to Neuroendocine Neoplasia
Introduction: Neuroendocrine neoplasias (NEN) are able to produce and secrete bioactive peptides and cause distinct syndromes related to their biological effects. The outcome will depend on the oncological disease as well as the hormonal syndrome

#22 A Case Illustrative of Phenotypic Heterogeneity and Challenges in the Management of Paraganglioma
Introduction: Paragangliomas (PGLs) are extra-adrenal, usually benign, highly vascularized tumors that originate from neural-crest-derived chromaffin cells. These tumors are subdivided as either sympathetic or parasympathetic, depending on their location and catecholamine production. Sympathetic PGLs are situated along the abdominal sympathetic trunk and usually produce catecholamines, whereas parasympathetic PGLs are located in the head and neck, and these usually do not produce catecholamines. PGLs may present as sporadic or inherited tumor syndrome, including MEN 2, with RET germline mutations, von Hippel-Lindau (VHL) disease due to germline mutations in VHL gene, and pheochromocytoma-PGL syndrome. The latter is frequently a hereditary condition and is caused by germline mutations in the SDHB, SDHC, or SDHC genes. Patients with familial PGLs may present at a younger age, often as multifocal tumors, with an increased risk of recurrence and a higher frequency of malignancy in those with SDHB mutations. SDH mutations induce angiogenesis and tumorogenesis through the inhibition of hypoxia-inducible factors (HIF)-propyl hyroxylase. A younger age at onset, malignancy, and a positive family history are clinical parameters of high specificity, but low sensitivity for diagnosis. Genetic analysis for mutations in SDH genes for the patient and family members, and surveillance for the affected patient and family members, are necessary where there are no clear clinical or family indicators for the syndrome. We present a case of a large abdominal malignant PGL in a 20-year-old pt. that went on without clinical detection for at least three years.

#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.

#82 A case of insulinoma successfully treated by means of long-acting somatostatin analogue
Introduction: Insulinoma is the most common hormonally active pancreatic neuroendocrine tumor. Effective treatment represents tumor surgery and medical therapy using diazoxide or streptozotocine. Somatostatin analogue therapy is rarely effective in this type of tumor.

#99 Gene mutations and Hypoxia Inducible Factor (HIF-1) expression as prognostic-predictive factors in pheochromocytomas/paragangliomas (P/P)
Introduction: P/P are rare tumors sporadically associated with familial disorders. In advanced/unresectable disease, no standard treatment has so far been well established. Recently a mutation of some genes (SDHB, SDHC, SDHD) involved in the pathogenesis of familial P/P was discovered. These mutations are often associated with an over-expression of HIF-1, which plays a central role in angiogenesis and cell proliferation. This pathway is known to be inhibited by some targeted therapies, such as sunitinib or sorafenib.
