Pheochromocytoma Treatment
Description
What is pheochromocytoma?
Pheochromocytoma is a rare disease in which tumors form in chromaffin cells of the body. Most pheochromocytomas start inside the adrenal gland (the adrenal medulla) where most chromaffin cells are located. There are two adrenal glands, one above each kidney in the back of the upper abdomen. Cells in the adrenal glands make important hormones that help the body work properly. Usually pheochromocytoma affects only one adrenal gland. Pheochromocytoma may also start in other parts of the body, such as the area around the heart or bladder.
Most tumors that start in the chromaffin cells do not spread to other parts of the body and are not cancer. These are called benign tumors. If a tumor is found, the doctor will need to determine whether it is cancer or benign.
Pheochromocytomas often cause the adrenal glands to make too many hormones called catecholamines. The extra catecholamines cause high blood pressure (hypertension), which can cause headaches, sweating, pounding of the heart, pain in the chest, and a feeling of anxiety. High blood pressure that goes on for a long time without treatment can lead to heart disease, stroke, and other major health problems.
If there are symptoms, a doctor may order blood and urine tests to see if there are extra hormones in the body. A patient may also have a special nuclear medicine scan. A CT scan, an x-ray that uses a computer to make a picture of the inside of a part of the body or an MRI scan, which uses magnetic waves to make a picture of the abdomen, may also be done.
Pheochromocytoma is sometimes part of a condition called multiple endocrine neoplasia syndrome (MEN). People with MEN often have other cancers (such as thyroid cancer) and other hormonal problems.
The chance of recovery (prognosis) depends on how far the cancer has spread, and the patient’s age and general health.
Stage Explanation
Stages of pheochromocytoma
Once pheochromocytoma is found, more tests will be done to see if the tumor has spread. This is called staging. A doctor needs to know the stage of the disease to plan treatment. The following stages are used for pheochromocytoma:
Localized benign pheochromocytoma
Tumor is found in only one area and has not spread to other tissues. Most pheochromocytomas do not spread to other parts of the body and are not cancer.
Regional pheochromocytoma
Cancer has spread to lymph nodes in the area or to other tissues around the original cancer. (Lymph nodes are small bean-shaped structures that are found throughout the body. They produce and store infection-fighting cells.)
Metastatic pheochromocytoma
The cancer has spread to other parts of the body.
Recurrent pheochromocytoma
Recurrent disease means that the cancer has come back (recurred) after it has been treated. It may come back in the area where it started or in another part of the body.
Treatment Option Overview
How pheochromocytoma is treated
There are treatments for all patients with pheochromocytoma. Three kinds of treatment are used:
- Surgery (taking out the cancer).
- Radiation therapy (using high-dose x-rays or other high-energy rays to kill cancer cells).
- Chemotherapy (using drugs to kill cancer cells).
Surgery is the most common treatment of pheochromocytoma. A doctor may remove one or both adrenal glands in an operation called adrenalectomy. The doctor will look inside the abdomen to make sure all the cancer is removed. If the cancer has spread, lymph nodes or other tissues may also be taken out.
Chemotherapy uses drugs to kill cancer cells. Chemotherapy may be taken by pill, or it may be put into the body by a needle in the vein or muscle. Chemotherapy is called a systemic treatment because the drug enters the bloodstream, travels through the body, and can kill cancer cells throughout the body.
Radiation therapy uses high-energy x-rays to kill cancer cells and shrink tumors. Radiation comes from a machine outside the body (external radiation therapy).
Treatment by stage
Treatments for pheochromocytoma depend on the stage of the disease, and the patient’s age and overall health. For more information, call the Cancer Information Service at 1-800-4-CANCER (1-800-422-6237); TTY at 1-800-332-8615.
Localized Benign Pheochromocytoma
Treatment will probably be surgery to remove one or both adrenal glands (adrenalectomy). After surgery the doctor will order blood and urine tests to make sure hormone levels return to normal.
Check for clinical trials from NCI's PDQ Cancer Clinical Trials Registry that are now accepting patients with localized benign pheochromocytoma.
Regional Pheochromocytoma
Treatment may be one of the following:
- Surgery to remove one or both adrenal glands (adrenalectomy) and as much of the cancer as possible. If cancer remains after surgery, drugs will be given to control high blood pressure.
- External radiation therapy to relieve symptoms (in rare cases).
- Chemotherapy.
Check for clinical trials from NCI's PDQ Cancer Clinical Trials Registry that are now accepting patients with regional pheochromocytoma.
Metastatic Pheochromocytoma
Treatment may be one of the following:
- Surgery to remove as much of the cancer as possible. If cancer remains after surgery, drugs will be given to control high blood pressure.
- External radiation therapy to relieve symptoms.
- Chemotherapy.
Check for clinical trials from NCI's PDQ Cancer Clinical Trials Registry that are now accepting patients with metastatic pheochromocytoma.
Recurrent Pheochromocytoma
Treatment may be one of the following:
- Surgery to remove as much of the cancer as possible. If cancer remains after surgery, drugs will be given to control high blood pressure.
- External radiation therapy to relieve symptoms.
- Chemotherapy.
Check for clinical trials from NCI's PDQ Cancer Clinical Trials Registry that are now accepting patients with recurrent pheochromocytoma.

There are also many other places to get materials and information about cancer treatment and services. Hospitals in your area may have information about local and regional agencies that have information on finances, getting to and from treatment, receiving care at home, and dealing with problems related to cancer treatment.
Find Publications
The NCI has booklets and other materials for patients, health professionals, and the public. These publications discuss types of cancer, methods of cancer treatment, coping with cancer, and clinical trials. Some publications provide information on tests for cancer, cancer causes and prevention, cancer statistics, and NCI research activities. NCI materials on these and other topics may be ordered online or printed directly from the NCI Publications Locator. These materials can also be ordered by telephone from the Cancer Information Service toll-free at 1-800-4-CANCER (1-800-422-6237), TTY at 1-800-332-8615.
