Currently, for the treatment of pheochromocytoma, it is primarily important that once diagnosed with pheochromocytoma, one should promptly visit the local hospital to arrange surgical treatment as soon as possible. By surgically removing the pheochromocytoma, this prevents the excessive secretion of catecholamines, which can lead to a hypertensive crisis in patients. Therefore, clinically, after diagnosing and locating the pheochromocytoma, receiving surgical treatment can often achieve satisfactory therapeutic outcomes. Typically, appropriate preparations must be made before surgery. Generally, prior to the operation, it is crucial to actively administer medications such as alpha-adrenergic blockers, beta-adrenergic blockers, calcium channel blockers, angiotensin-converting enzyme inhibitors, vasodilators, and catecholamine synthesis inhibitors to effectively treat and stabilize blood pressure.

Pheochromocytoma clinical manifestations

Pheochromocytoma typically presents with severe hypertension, with blood pressure even reaching above 200/140 mmHg, accompanied by significant discomfort, such as profuse sweating, chest pain, obvious difficulty in breathing, chest tightness, shortness of breath, and other clinical manifestations. Moreover, if not treated timely and effectively, it can even lead to a hypertensive crisis. It also poses a severe threat to the patient’s heart, kidneys, liver, and brain tissues. Some patients might develop cerebrovascular diseases due to very high blood pressure, such as hypertensive cerebral hemorrhage, which can threaten the patient's life.

Pheochromocytoma hypertension medication

For pheochromocytoma, it is often recommended to use adrenergic receptor blockers for the treatment of hypertension. These can be divided into α-adrenergic receptor blockers and β-adrenergic receptor blockers. In addition, all other types of antihypertensive drugs can also be used frequently during treatment. For example, angiotensin-converting enzyme inhibitors and calcium channel blockers also play a helpful role in the treatment of pheochromocytoma. Besides pharmacological treatment, the fundamental approach is to perform qualitative and localization diagnosis, and after confirmation, to surgically remove the pheochromocytoma completely to fundamentally achieve therapeutic goals.

Is pheochromocytoma a cancer?

Pheochromocytoma is not a cancer. It is a special type of tumor tissue that usually originates from the neuroectodermal chromaffin tissue. It can secrete catecholamines. Based on the specific origins of the tumor cells, it can be divided into types such as parasympathetic, paraganglioma, sympathetic, and ganglioneuroma. Most often, it presents with long-term hypertension, which can cause damage to the heart, brain, and kidneys due to prolonged hypertension, or severe increases in blood pressure can lead to hypertensive brain hemorrhage, thereby endangering the patient's life. Early treatment is often necessary.

How is pheochromocytoma diagnosed?

For the examination of pheochromocytoma, it is generally recommended to use qualitative or localization diagnostic methods. Qualitative examinations typically involve collecting metabolites of catecholamines from urine and blood to further facilitate a definitive diagnosis. Localization examinations are conducted through abdominal ultrasound, CT, or MRI to further identify the specific growth location of the pheochromocytoma. After a definitive diagnosis through qualitative and localization examinations, surgery is generally recommended to effectively remove the pheochromocytoma. Additionally, antihypertensive medication can be used to help control symptoms.

Can pheochromocytoma be cured?

Currently, with the continuous advancement of surgical techniques, pheochromocytomas can be treated promptly and effectively, achieving favorable outcomes. Once a pheochromocytoma is diagnosed and accurately localized, it is advisable to promptly proceed with surgical intervention. Removing the tumor surgically usually results in effective treatment outcomes. Before surgery, imaging studies and biochemical tests are used for the qualitative and locational diagnosis. After the nature and location of the tumor are clearly identified, the success rate of the surgery can also be increased. Pre-operative use of adrenergic receptor blockers can effectively manage the condition, leading to a reduction in blood pressure and lessening the load on the heart, thereby ensuring smooth conduct of the surgery.
