Content Validation of Quality of Life and Symptom Questionnaires for Pheochromocytoma and Paraganglioma
Summary
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.

Medical and Biotech [MESH] Definitions
Prazosin
A selective adrenergic alpha-1 antagonist used in the treatment of heart failure, hypertension, pheochromocytoma, Raynaud's syndrome, prostatic hypertrophy, and urinary retention.
Piperoxan
A benzodioxane alpha-adrenergic blocking agent with considerable stimulatory action. It has been used to diagnose PHEOCHROMOCYTOMA and as an antihypertensive agent.
Alpha-methyltyrosine
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)
Phentolamine
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.
Paraganglioma
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)
Clinical Trials
Phase 1-2 Study of Iobenguane (MIBG) I 131 in Patients With Malignant Pheochromocytoma/Paraganglioma
The purpose of this study is to determine whether iobenguane I 131 is safe and effective in patients with malignant pheochromocytoma or paraganglioma.
Specificity of Elevated Plasma EM66 Levels in Pheochromocytoma
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...
RAD001 in Pheochromocytoma or Nonfunctioning Carcinoid
- 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...
Diagnosis and Treatment of Pheochromocytoma
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...
This clinical trial is designed to evaluate the effectiveness and collect additional safety information on Ultratrace Iobenguane I 131 for the treatment of relapsed/refractory (to other tr...

Background: Clinical diagnosis of pheochromocytoma is difficult for some adrenal tumors. Aim: Herein, we review clinical and pathological findings of 31 cases with radiographically diagnosed pheochrom...
Malignant pheochromocytoma: new malignancy criteria.
PURPOSE: The pathological diagnosis of malignancy in pheochromocytomas remains a controversial issue. According to the WHO, malignancy is defined in the presence of metastasis. M...

Pheochromocytoma crisis presenting with cardiogenic shock.
Pheochromocytoma is a catecholamine-secreting tumor of the adrenal glands whose typical presentation includes the triad of headache, palpitations, and diaphoresis. Pheochromocytoma crisis is an urgent...
OBJECTIVES: We retrospectively reviewed the outcomes after laparoscopy versus an open procedure for the resection of pheochromocytoma. PATIENTS AND METHODS: Forty-nine patients were enrolled into the...
