background pancreatic neuroendocrine tumors (pnets) are rare tumors with variable malignant potential, prognosis, and survival. we aimed to assess the characteristics of patients with non- functional pnet  in our hospital . methods from nov 2010 to nov 2013 , all patients who came to endosonography unit of shariati  hospital , tehran , iran , and   had pancreatic lesions were assessed . tumor s...

neuroendocrine tumors (nets) constitute a heterogeneous group of neoplasms including carcinoids, pancreatic neuroendocrine tumors, pituitary tumors, medullary thyroid carcinoma and phaeochromocytomas. the symptoms and the outcome of nets differ considerably between patients depending on several factors. by labelling tracers with a radioisotope, the tracer acts as a carrier to deliver the radioa...

neuroendocrine tumors are most often located in the intestine and lungs but they can arise from other areas of the body. limited data is available on epidemiology and clinical patterns of neuroendocrine tumors in iran. we analyzed medical records of 34 patients from 2 cancer centers (emam khomeini hospital and omid charity cancer center) in west azarbaijan province of iran with neuroendocrine t...

radioiodinated meta iodobenzylguanidine (mibg) is one of the important radiopharmaceuticals in nuclear medicine. [123/131i]mibg is used for imaging of adrenal medulla, studying heart sympathetic nerves, treatment of pheochromacytoma and neuroblastoma. for clinical application, radioiodinated mibg is prepared through isotopic exchange method, which includes replacement of radioactive iodine in a...

Parathyroid hormone-related protein producing pancreatic neuroendocrine tumors have been infrequently reported. Herein, we report a case of an Iranian woman who had such a tumor during pregnancy, and gave birth to a female neonate with esophago-tracheal fistula and imperforated anus. Hypercalcemia was diagnosed at postpartum because of elevated serum calcium levels in the neonate and neurologic...

pancreatic neuroendocrine tumors (pnet) are uncommon pancreatic neoplasms, accounting for 1-2% of all pancreatic tumors. however, they have a better prognosis and long-term survival compared to exocrine pancreatic cancer. pnets can be divided into functional or non-functional based upon whether or not they excrete active substances relevant to specific clinical syndromes. skeletal muscle metast...

Background: Certain marker studies have practical importance in the biology of prostate cancer. The purpose of this study was to determine whether the quantification of certain neuroendocrine and proliferative markers obtained during transurethral resection or prostatectomy, would help in the prognostic evaluation of prostatic adenocarcinomas. Methods: The present study was performed on samples...
