#628 Sequential Chemo-Radiation Therapy for Locally Advanced Neuroendocrine Carcinoma of Head and Neck
Introduction: Neuroendocrine carcinomas (NECs) of the head and neck are considered an infrequent clinico-pathological entity. Combined modality treatment represents an established therapeutic option for poorly differentiated forms where distant metastasis is a common pattern of failure.

#54 The clinical challenge of patients with a thoracic or neck neuroendocrine tumor: a retrospective analysis from a single Irish institution
Introduction: Thoracic and neck neuroendocrine tumors (T-N-NETs) represent a rare and intriguing condition and the management of patients with a NET localized at the thorax or neck can be extremely problematic. An expert and multidisciplinary approach is generally required for the optimal management of NET patients. A systematic multidisciplinary approach to NET patients has been recently established at our institution.

#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.

#946 Immunohistochemical Staining of Catecholamine-Synthesizing Enzymes in Head and Neck Paraganglioma Tissue
Introduction: Head and neck paragangliomas (HNPGLs) are non-producing neuroendocrine tumors, alhough 19-28% of patients have an increased dopamine production. The high sensitivity of 18F-DOPA PET also shows that these tumors might be able to synthesize catecholamines.

#399 Malignant Carotid Body Tumors (CBTs), Clinical Presentation, Investigations and Their Management
Introduction: Malignant CBTs are rare (incidence 0.012%) and their management is not well settled. We present 2 pts. with malignant CBTs to define their presentation, investigations done and treatment undertaken w/ FU.

#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.

#273 The Succinate Dehydrogenase Genetic Testing in Patients with Extra-adrenal Paragangliomas: The Portuguese Cancer Center (Lisboa) Experience
Introduction: Extra-adrenal paragangliomas (PGLs) occur as sporadic or familial entities, the latter mostly in association with germline mutations of the SDHB, SDHC or SDHD genes.

#372 A Retrospective Analysis of Neuroendocrine Tumors (NETs) in West Azarbaijan of Iran
Introduction: NETs are most often located in the intestine and lungs but they can occur in other areas of the body. Limited data are available on epidemiology and clinical patterns of NETs in Iran.
