#1689 The Prognostic Value of the Expression of Cytokeratin 7 and 19 in Lungs and Pancreas Neuroendocrine Tumors
Introduction: The expression of cytokeratins (CK) 7,19 rarely occurs in the low grade neuroendocrine tumors (NET) of lung and pancreas. It is known that part of the low grade typical (TC) and atypical (ATŠ”) carcinoids of lung and pancreas (pNET-G1,G2) can progress quickly and to metastasize. It is important to distinguish NET with a less differentiated cells immunophentype.

#1267 Two Cases of Parathyroid Cancer with Pulmonary Metastasis
Introduction: Parathyroid cancer(PC) is a rare disease accounting for less then 1% of all patients with primary hyperparathyroidism. The prognosis of patients with parathyroid carcinoma is variable; more than 50% have a persistent or recurrent disease due to a regional or distant disease.

#30 Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia
Introduction: Normal adult lungs contain scattered pulmonary neuroendocrine cells (PNEC). Reactive PNEC hyperplasia is commonly observed in persons who live at high altitude, in cigarette smokers, and in numerous lung diseases. Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia (DIPNECH) is a rare entity in which PNEC hyperplasia appears without predisposing conditions. According to the 1999 WHO lung tumor classification, DIPNECH is thought to be primarily a neuroendocrine proliferative process, which can be associated with carcinoid tumors and with a clinical picture of constrictive obliterative bronchiolitis. To date, available data regarding the treatment and the prognosis of this rare condition is limited.

#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.

#106 Gastroenteropancreatic neuroendocrine tumors: single institution clinicopathological study
Introduction: Neuroendocrine cells are widely distributed throughout the body, and neoplasms from these dispersed cells can arise at many sites. They are distinguished into two broad categories: 1) Tumors identified as small cell lung carcinomas with biology and natural history of a high-grade malignancy and characteristics of small cell undifferentiated or anaplastic appearance by light microscopy. The WHO categorizes these tumors as poorly-differentiated neuroendocrine carcinomas; 2) Well-defined neuroendocrine tumors (NETs) with variable, but most lyindolent biologic behavior and characteristic well-differentiated histologic features. The majority arise in the gastrointestinal tract and collectively they are referred as gastroenteropancreatic neuroendocrine tumors (GEP/NETs). They include carcinoid tumors, pancreatic islet cell tumors (gastrinoma, insulinoma, glucagonoma, VIPoma, somatostatinoma), paragangliomas, pheochromocytomas, and medullary thyroid carcinomas. The WHO classifies the GEP/NETs as well-differentiated NETs (carcinoid tumors) if they are noninvasive and have benign behavior or uncertain malignant potential. In contrast, GEP/NETs with characteristics of low-grade malignancy with invasion of the muscularis propria or beyond, or metastases, are characterized as well-differentiated neuroendocrine carcinomas (malignant carcinoids). Pancreatic islet cell tumors, whether functioning or not, are classified as well-differentiated NETs or well-differentiated neuroendocrine carcinomas, due to the (depending on) histologic characteristics. The WHO classification for gastroenteropancreatic NETs based on stage (ie size and presence of metastases) and grade (mitotic rate, perineural and lymphovascular invasion, Ki-67 proliferative index) categorizes them as well-differentiated NETs, e.g., carcinoid tumors, or as well-differentiated neuroendocrine carcinomas.

#161 Low Dose Multiple Cycle (LD/MT) Peptide Receptor Radionuclide Therapy: a new concept for the treatment of well-differentiated metastatic neuroendocrine tumors
Introduction: It has been shown experimentally that low dose radiation can effectively kill slow growing cancer cells. Also, external beam radiation therapy applies a fractionated delivery of radiation dose to reduce toxicity with equal or even better therapeutic efficacy.

#177 Dissociation Between Iodine-131 meta-iodobenzylguanidine (MIBG) Scintigraphy and Radiolabeled Octreotide in the Localization and Management of Sporadic Malignant Pheochromocytoma: An Impact on Management
Introduction: The Rx of malignant pheochromocytomas w/negative MIBG scan remains a challanging problem. Octreoscan is helpful in localization and Rx planning in such cases. Rx using SST analog & PRRT is a desirable goal.

#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.
