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...
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 a tumor of the adrenal gland. This tumor is typically benign (not cancerous) and can be cured by surgical removal. However, pheochromocytomas produce neurohormones ca...
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...
Pheochromocytoma and Ganglioneuroblastoma are separate diseases and a rare combination in which the diagnosis can only be confirmed by pathological examination after tumor excision. We reported here a...
We report the surprising intense uptake of F-FDOPA in a right adrenal metastasis of a poorly differentiated metastatic adenocarcinoma of unknown primary mimicking a pheochromocytoma in a hemodialyzed ...
Patients with pheochromocytoma (pheo) show presence of multilocular adipocytes that express uncoupling protein (UCP) 1 within periadrenal (pADR) and omental (OME) fat depots. It has been hypothesized ...
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)
