The purpose of this study is to determine whether iobenguane I 131 is safe and effective in patients with malignant pheochromocytoma or paraganglioma.
Pheochromocytoma or paraganglioma are tumors generating hypertension as a symptom. Different biological tests are currently available to diagnose these tumors. However, they all lack speci...
- According to Martin F et al, AKT is highly phosphorylated in phenochromocytoma but not in benign adrenocortical tumors. - In nonfunctioning carcinoid, the PI3K/AKT/mTOR pathway...
Pheochromocytomas and paragangliomas are neural crest-derived tumors of the nervous system that are often inherited and genetically heterogeneous. Genetic screening is recommended for pati...
The FIRSTMAPPP study is a randomized, double-blind, phase II, international, multicenter study which aims to determine the efficacy of Sunitinib on the progression-free survival at 12 mont...
Pheochromocytoma is an endocrine tumor that causes hypertension, facial pallor, and headache. Pheochromocytoma patients rarely present with acute heart failure or cardiogenic shock.
Giant cystic pheochromocytoma (>10cm) is rare with only a few cases described in the literature. Preoperative diagnosis is very difficult because clinical, biochemical and radiologic finds are usually...
This study aims to examine the expression profiles of the miR-183 cluster (miR-96/182/183) in pheochromocytoma. Pheochromocytoma tissues were prospectively collected from 50 patients with pheochromocy...
Catecholamine excess from pheochromocytoma results in cardiovascular symptoms such as arterial hypertension and tachycardia and induces metabolic alterations including glucose intolerance and increase...
(123) I-meta-iodo benzyl guanidine (MIBG) scans are considered the gold standard imaging in neuroblastoma; however, flouro deoxy glucose positron emission tomography (FDG-PET) scans have increased sen...
A selective adrenergic alpha-1 antagonist used in the treatment of heart failure, hypertension, pheochromocytoma, Raynaud's syndrome, prostatic hypertrophy, and urinary retention.
A benzodioxane alpha-adrenergic blocking agent with considerable stimulatory action. It has been used to diagnose PHEOCHROMOCYTOMA and as an antihypertensive agent.
An inhibitor of the enzyme TYROSINE 3-MONOOXYGENASE, and consequently of the synthesis of catecholamines. It is used to control the symptoms of excessive sympathetic stimulation in patients with PHEOCHROMOCYTOMA. (Martindale, The Extra Pharmacopoeia, 30th ed)
A nonselective alpha-adrenergic antagonist. It is used in the treatment of hypertension and hypertensive emergencies, pheochromocytoma, vasospasm of RAYNAUD DISEASE and frostbite, clonidine withdrawal syndrome, impotence, and peripheral vascular disease.
A neural crest tumor usually derived from the chromoreceptor tissue of a paraganglion, such as the carotid body, or medulla of the adrenal gland (usually called a chromaffinoma or pheochromocytoma). It is more common in women than in men. (Stedman, 25th ed; from Segen, Dictionary of Modern Medicine, 1992)
