No results posted yet for this study

Summary

The adrenal glands, located atop the kidneys, normally produce several types of hormones. Tumors of these glands may or may not secrete hormones. It is not known what causes these tumors or why some secrete hormones and others do not. Some of the tumors are benign and confined to the adrenal gland, and others are malignant (cancerous), and can spread to other parts of the body. This study will investigate how adrenal gland tumors develop, why some secrete steroid hormones and others do not, and why some are benign and others malignant.

Patients between 3 and 70 years old with a known or suspected adrenal gland tumor may be eligible for this study. Participants will be hospitalized for 7 to 10 days for various tests and procedures that may include the following:

1. Medical history and physical examination, including body measurements, as appropriate. Children and adolescents will have Tanner staging, including examination of the genitals, to determine the extent of sexual maturity.
2. 24-hour urine collection to measure hormones in the urine.
3. Imaging studies, including magnetic resonance imaging (MRI) of the brain, computed tomography (CT) and other X-ray studies.
4. Blood tests to see if the tumor secretes hormones in response to specific stimuli, including exercise, food, and various hormones. The hormones are given through an intravenous catheter, or IV a thin plastic tube inserted into an arm vein. After the stimulus, blood is drawn through the same IV every 30 minutes for up to 3 hours to measure hormone levels. Based on the results of these tests, some patients may have additional blood tests to check hormone response to special foods, an IV salt solution, or other hormones or drugs given either IV or by mouth (in pill form).
5. Photographs to document the effects on the body of abnormal hormone secretion from the adrenal tumor.
6. Small samples of blood and tumor tissue for research and DNA (genetic) analysis.

A discussion of treatment options will be based on the results of tests. If surgery to remove the tumor is recommended, the procedure can be done at NIH under this study protocol. If a malignant tumor is found that cannot be treated surgically, chemotherapy or radiation therapy may be recommended. These options are not offered under this protocol, but may be available under a different NIH study (for example, at the National Cancer Institute). Referrals will be made at the patient s request.

Patients who had surgery may be followed at the NIH outpatient clinic for 1 year after surgery. Patients with certain types of tumors may continue to be followed at NIH once a year for up to 5 years.

A registry of study participants will be created to keep records and correlate medical histories with tissues kept at NIH. The registry will also be used to inform participants of research studies they may be interested in. No individuals or organizations outside of NIH will have access to the registry.
