Pheochromocytomas generally require a visit to urology for treatment. Initially, they mostly present with symptoms of hypertension, leading many to first visit cardiology. After differential diagnoses have ruled out other causes and confirmed pheochromocytoma, patients must then seek treatment from urology. Pheochromocytomas are generally located in the adrenal glands, hence they require surgical removal by a urologist. It is crucial to strictly control blood pressure during surgery, as fluctuations can be severe and significantly impact the patient's physical and mental health. Therefore, if a pheochromocytoma is detected, it is critical to seek timely medical treatment for a relatively better prognosis.

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.

Is surgery necessary for pheochromocytoma?

For patients diagnosed with pheochromocytoma, it is recommended to undergo surgery as soon as possible. Complete surgical removal of the tumor often results in a very good therapeutic effect. Before surgery, some medications can be appropriately used for treatment. For example, it is advised to choose adrenergic receptor blockers, which can significantly improve the patient's condition. These can be taken orally before the operation to help gradually regulate blood pressure, or other medications such as calcium channel blockers, angiotensin-converting enzyme inhibitors, and vasodilators may be used. Only through a combination of medication and surgery can satisfactory treatment results be achieved.

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.

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.

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.
