The purpose of this qualitative study is to evaluate the clarity and comprehensiveness of two disease-specific questionnaires, and to evaluate how effective these questionnaires are at assessing the quality of life and symptoms of patients with pheochromocytoma or paraganglioma.
Observational Model: Case-Only, Time Perspective: Cross-Sectional

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 a disease where catecholamines are secreted. If pheochromocytoma occurs during pregnancy, it can be difficult to diagnose because it is similar to pregnancy-induced hypertension. F...
Pheochromocytoma is a rare tumour which is usually suggested by sustained or paroxysmal hypertension however the spectrum of the presentation of pheochromocytoma continues to expand and hypertension m...
This study aims to investigate the effect of heat shock protein 90 (HSP90) inhibitor 17-allylamino-17-demethoxygeldanamycin (17-AAG) in the malignant pheochromocytoma using a xenograft mouse model. Tr...
: Pheochromocytoma crisis is a feared and potentially lethal complication associated with excess release of catecholamine from the tumor, which might lead to multiple organ failure (MOF). The definiti...
Aberrant cellular oxygen sensing (pseudo-hypoxia) is a leading theory for development of pheochromocytoma (PHEO) and paraganglioma (PGL).
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)
