#3032 Lung Side and Site: The Importance of Location and the Prognostic Implication in Lung Neuroendocrine Tumors
Introduction: Lung neuroendocrine tumors (NET) are classified as typical (TC) and atypical carcinoids (AT), according to their mitotic count and the presence of necrosis. However, a role for tumor side (right vs left) and location (central vs peripheric) has not been established so far.

#381 Ovarian Primary Neuroendocrine Tumor Combined with a Monodermal Teratoma: A Case Report
Introduction: Primary neuroendocrine tumor of ovary is an uncommon neoplasm that may be found as a solitary mass or in association with teratomas or mucinous tumors.

#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.

#474 Difficulties in Diagnosis and Management of Neuroendocrine Tumors of the Head and Neck: A Case Report
Introduction: Primary neuroendocrine carcinomas (NEC) are uncommon head and neck malignancies. They present with a varied histopathologic spectrum in sinonasal and other subsites.

#71 Treatment of unresectable neuroendocrine liver tumors with Y-90 microsphere
Introduction: The primary therapy of liver lesions of NET is surgery but it is most possible for all patients. Selective internal radiation therapy (SIRT) is a newly available method to treats liver metastases.

#111 Atypical lung carcinoid tumor metastatic to endocrine glands and bone marrow
Introduction: Bronchopulmonary neuroendocrine tumors (BP-NETs) comprise 20% of all lung cancers. Typical low grade carcinoid tumors (TC) represent the majority of BP-carcinoids. Intermediate grade atypical carcinoid tumors (AC) are less often encountered but more aggressive. Although metastatic dissemination to mediastinal lymph nodes, liver, skeleton and central nervous system (CNS) is common, involvement of the endocrine glands has rarely been reported.

#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.

#1025 Evaluation of Patients (pts) with Neuroendocrine Tumors at First Cardiological Consultation with Echocardiographic (Echo) Method. Argentum Group
Introduction: The incidence of carcinoid tumors is approximately 1 in 75,000 of the population of whom 50% develop carcinoid syndrome. Once carcinoid syndrome has developed, approximately 50% of these patients develop carcinoid heart disease which typically causes abnormalities in the right side of the heart.

#47 Plasma CCN2/connective tissue growth factor is associated with right ventricular dysfunction in Patients with Neuroendocrine Tumors
Introduction: Carcinoid heart disease (CHD) is a known complication of neuroendocrine tumors (NETs), particularly of those arising from the small intestine, appendix and proximal colon (previously known as mid-gut carcinoids). CHD is characterized by right heart fibrotic lesions and has traditionally been defined by the degree of valvular involvement, most commonly in the form of tricuspid regurgitation. Right ventricular (RV) dysfunction due to mural involvement may also be a manifestation. Connective tissue growth factor (CCN2) is upregulated in many fibrotic disorders. Increased tumor expression of CCN2 has been shown in patients with small intestinal NETs associated with peritoneal fibrosis. At present, its role in carcinoid heart disease is unknown.
