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.

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 typical manifestations

For pheochromocytoma, the term usually refers to tumors arising from the chromaffin tissue of the neural crest. Clinically, the main typical symptoms include severe hypertension, along with nausea, vomiting, intense headache, and dizziness. Additionally, it may also cause the patient to be in a continuous high metabolic state, characterized by persistent hyperglycemia, nausea, vomiting, and excessive sweating. If not treated promptly and effectively, it may pose serious threats to the patient's heart, brain, and kidneys. In severe cases, it could even be life-threatening. Surgery is commonly recommended for treatment.

Can malignant pheochromocytoma be cured?

When pheochromocytoma becomes malignant, it can be cured through clinical approaches, although malignant pheochromocytoma mainly refers to those that have distant metastases. It primarily exhibits aggressive growth or is accompanied by metastases to other organs, and surgery cannot completely remove it, leading to a high recurrence rate post-surgery. Generally, the five-year survival rate for patients with malignant pheochromocytoma does not exceed half. If treated with chemotherapy or arterial embolization, it can control the patient's blood pressure and alleviate the tumor burden, thereby extending the survival period. In summary, the treatment of malignant pheochromocytoma is relatively challenging, has a high recurrence rate, and poses a significant threat to human life.

Pheochromocytoma secretes what?

Pheochromocytoma typically refers to tumors that originate from chromaffin tissue of the neural crest, and more often the tumors arise from sympathetic or parasympathetic ganglia, primarily secreting catecholamines. Many patients, due to long-term secretion of catecholamines, experience significant hypertension; severe cases may lead to hypertensive crises and cause serious damage to the heart, brain, and kidneys, or even life-threatening conditions due to severe hypertension. In most cases, if diagnosed and treated early, satisfactory treatment results can often be achieved. Those with pheochromocytoma should visit local hospitals in a timely manner for early diagnosis and treatment.

What tests are used for pheochromocytoma?

For pheochromocytoma, it is usual to perform both qualitative and localization diagnoses. The qualitative diagnosis is generally based on the measurement of catecholamines and their metabolites in the patient's blood and urine. Localization diagnosis is more commonly determined through methods such as CT scans, MRI, and ultrasound to pinpoint the specific location of the pheochromocytoma, facilitating surgical treatment. Most patients achieve satisfactory results from surgery. Additionally, treatment may include the use of antihypertensive drugs. With combined treatment, most patients can achieve satisfactory results. It is recommended to seek treatment at a well-known tertiary hospital locally.
