For pheochromocytoma, it is still best to receive surgical treatment. Conservative treatment through medication alone has limited effects. In most cases, gradually increasing blood pressure leads to serious symptoms or signs in the patient, such as palpitations, shortness of breath, labored breathing, chest pain, accompanied by profuse sweating, and even severe panic and feelings of impending doom, posing serious life-threatening risks to the patient. In terms of treatment, it is advised to prioritize surgical removal of the tumor, as this can fundamentally lead to a complete cure. Additionally, appropriate medication can be used before and after the surgery to assist in treatment.

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.

What size of pheochromocytoma is malignant?

The size of pheochromocytomas and the benign or malignant nature of the tumor are not greatly related. Usually, most are familial pheochromocytomas, which are most commonly bilateral, but they have a relatively high recurrence rate and are difficult to treat with fewer available treatment options. Once a pheochromocytoma is detected, it should be taken seriously and treated promptly. The presence of a tumor often indicates that it has developed to the mid and late stages, where it becomes relatively difficult to cure. Regardless of whether the tumor is large or small, it must be taken seriously and treated with care, otherwise, it may easily worsen and affect health.

Pheochromocytoma Test Items

For pheochromocytoma, the usual tests include routine blood tests, routine urine tests, and biochemical examinations. Specific tests mainly involve collecting blood and urine catecholamine metabolites to help diagnose the condition. Furthermore, further localization diagnostics are conducted on the patient via abdominal ultrasound, as well as CT or MRI scans, to determine the specific location of the pheochromocytoma growth. Further examinations are conducted in preparation for subsequent surgery, with treatment generally recommended to be surgical. During treatment, antihypertensive drugs are used in conjunction to control blood pressure and maintain stability of the condition.

How is pheochromocytoma diagnosed?

For patients with pheochromocytoma, comprehensive examinations are necessary for diagnosis. For instance, measuring catecholamines and their metabolites in blood or urine can help determine if there is a noticeable increase in catecholamine levels. Furthermore, adrenal CT scans can be used to assess the condition, where in many cases, significant occupying lesions can be detected through adrenal CT scans. In addition, other related tests also hold diagnostic value and significance, such as magnetic resonance imaging, ultrasound, and related nuclear scanning tests, which can assist in qualitative and locational diagnosis.

Malignant symptoms of pheochromocytoma

For pheochromocytoma, if not treated adequately, it often leads to severe hypertensive crises in patients, characterized by extreme spikes in blood pressure accompanied by profuse sweating, palpitations, shortness of breath, chest pain, and numbness in the limbs. Excessively high blood pressure can easily trigger pathological changes in the heart, kidneys, liver, and brain tissues, possibly leading to hypertensive brain hemorrhage, and even endangering the patient's life. Therefore, if pheochromocytoma is not managed and treated properly, it often results in critical illness and might even endanger the patient's life. It is recommended that once diagnosed, hospitalization should be sought promptly, and surgical treatment should be considered if necessary.
