Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 3 to 70 years
- All sexes
- No healthy volunteers
- Child, Adult, Older adult
Study population: Research subjects who present with Adrenal adenoma, adrenal carcinoma, Cushing syndrome, virilizing adrenals tumor, feminizing adrenal tumor, massive macronodular adrenocortical disease, ACTH-independent macronodular adrenal hyperplasia
Who may be able to join
- Patients are adults or children with evidence for the existence of a tumor of the adrenal glands, as indicated by previously obtained imaging studies and/or biochemical investigation of hormonal secretion. This condition is meant to include the possibility of individuals with "sub-clinical" hormone secretion syndromes, which may be detectable at the biochemical level even in the absence of frank clinical signs/symptoms.
- All eligible patients are invited to participate in this protocol, regardless of sex, race or ethnic origin. All populations appear at risk for adrenal tumors, and therefore the subject population can include Native Americans, Asian/Pacific Islanders, Caucasian, Hispanic, and Black individuals. Patients will be accepted for evaluation based on referral from clinicians, or may be self-referred, if they can provide evidence supportive of the diagnosis of hormone over-secretion.
- Patients must be willing to return to the NIH for follow-up evaluation.
- Patients may withdraw from the study at any time.
Who cannot join
- Children less than 3 years old will be excluded from the protocol because of the limited resources available at the NIH for the care of infants of this age.
- Individuals over the age of 70 years of age will be excluded because of the possibility of comorbidities that may significantly affect appropriate initial work-up and post-operative management. In addition, research data may be compromised by the inability to interpret data collected from patients over the age of 70 years that may be on multiple medications for a variety for reasons.
- Women who are pregnant or nursing will be excluded from the hyperaldosteronism arm of the protocol. Women with adrenal tumors secreting cortisol or other adrenal hormones may benefit clinically from evaluation and treatment of their tumor, and will be considered for enrollment when clinically indicated.
- Individuals whose medical status will not allow them, for safety reasons, to participate in the provocative testing or who have unacceptably high risk for surgical morbidity and mortality will be excluded from the protocol, as they will not be able to participate profitably in the research aspects of this protocol.
- Individuals found to have an known inherited syndrome as the cause for hormone oversecretion will be excluded from participation in this protocol, as the mechanisms of hormone oversecretion and tumorigenesis is likely to be distinct in these individuals. Specific examples of syndromes to may be excluded from this protocol include individuals with Carney Complex, McCune-Albright syndrome, and MEN-1. If inquiries are received from such patients, they will be referred to the appropriate ongoing protocols, if possible.

About this study
Official title: Clinical and Molecular Analysis of ACTH-Independent Steroid Hormone Production in Adrenocortical Tissue
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:
Read more
- 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.
- 24-hour urine collection to measure hormones in the urine.
- Imaging studies, including magnetic resonance imaging (MRI) of the brain, computed tomography (CT) and other X-ray studies.
- 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).
- Photographs to document the effects on the body of abnormal hormone secretion from the adrenal tumor.
- 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.
Read the detailed description
The adrenal glands are the major source in the body of the steroid hormones. In normal physiology, the pituitary hormone ACTH regulates the secretion of glucocorticoids, while the secretion of mineralocorticoids such as aldosterone is controlled by the renin-angiotensin system. In addition to these two classes of steroids, the adrenal gland secretes lesser amounts of intermediate metabolites as well as dehydroepiandrosterone (DHEA) and its sulfated product (DHEAS) and androstenedione, testosterone, estrogen, and estrone. Dysregulated secretion of any of these hormones can be caused by sporadic adrenocortical adenomas or carcinomas, with the development of specific clinical syndromes depending on the identity of the hormones secreted. In at least a subset of cortisol-producing adrenocortical neoplasms, the presence of ectopic or abnormal receptors has been described, resulting in the regulation of cortisol and/or aldosterone by non-physiologic stimuli. The present study will serve as a mechanism to investigate individuals with steroid hormone-secreting adrenocortical tumors of all types for the purpose of identifying hereditary, congenital, or acquired defects leading not only to hormone oversecretion, but also to tumor formation. One of the first goals of the study was (until very recently) to examine the prevalence of ectopic receptor expression in cortisol- and/or aldosterone- hormone secreting adrenocortical tumors. This led to the understanding of the ontogeny of these tumors and the development of novel therapeutic strategies (e.g., receptor antagonists) to control hormone oversecretion. We currently use this information for the evaluation and treatment of our patients. An important research goal of the study is to identify novel genetic defects leading to tumors of the adrenal gland. This is done through a set of methods, from sequencing of the collected DNA to analysis of the expression of large sets of genes using gene array/gene chip analysis. This information may help to identify patients who would benefit from more aggressive intervention strategies, especially those with potentially malignant tumors. This study also provides the patient cohort necessary for the establishment of a bank of tissues of varying tumors of the adrenal cortex, which may serve in the future as an experimental resource to test new diagnostic and therapeutic methods. Finally, an important and more recent goal of this study is to investigate the effects of excess aldosterone on renal, cardiac, metabolic, and bone systems in patients with primary hyperaldosteronism, an important subgroup of patients with adrenocortical tumors. Patients with hyperaldosetronism have not been studied with the same rigor as patients with hypercortisolism in the past; this study aims at investigating the relative contribution of hyperaldosteronism in the etiopathogenesis of a number of clinical problems in patients with adrenocortical lesions and hypertension.

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
To study the contribution of ectopic/abnormal membrane hormone receptor expression in the adrenal gland to the pathogenesis of primary adrenocortical hormone over-secretion syndromes (time frame: This is an ongoing project). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00005927, which also lists 8 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Nov 2026.
