- Adrenal tumors are a common kind of tumor. Some of these secrete extra cortisol into the body, which can lead to diabetes, obesity, and other diseases. Some people with extra cortisol will show symptoms like bruising and muscle weakness. Others will show no signs. This is called subclinical hypercortisolism. Some of these adrenal tumors become malignant. Researchers want to know the best way to treat people with subclinical hypercortisolism. They want to know if removing the tumor by surgery reduces the long-term effects of the disease.
- To see if removing an adrenal tumor by surgery improves blood pressure, diabetes, obesity, osteoporosis, or cholesterol, and cancer detection.
- Adults 18 and older with an adrenal tumor and high cortisol levels.
- Participants will be screened with medical history, blood tests, and a computed tomography (CT) scan.
- Participants will have a baseline visit. They will have blood and urine tests and 7 scans. For most scans, a substance is injected through a tube in the arm. Participants will lie still on a table in a machine that takes images.
- Participants will have surgery to remove their tumor. Some will have surgery right away. Some will have surgery 6 months later, after 2 follow-up appointments.
- Participants will have 4 follow-up visits in the first year after surgery. They will have 2 visits the second year, then yearly visits for 3 years. At each follow-up visit, they will have scans and blood tests.

- Proportion of Patients That Have Normalization and/or Improvement of Metabolic Complications After Adrenalectomy [ Time Frame: Assessed at 6 months ]Normalization and/or improvement of metabolic complications including hypertension, diabetes, osteoporosis, hypercholesterolemia and/or obesity after adrenalectomy is defined as 35% of patients who improve with surgery versus 5% who do not have surgery.
- Count of Participants With Serious and Non-serious Adverse Events Assessed by the Common Terminology Criteria in Adverse Events (CTCAE v4.0) [ Time Frame: Date treatment consent signed to date off study, approximately 39 months and 27 days ]Here is the count of participants with serious and non-serious adverse events assessed by the Common Terminology Criteria in Adverse Events (CTCAE v4.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned.
- Proportion of Patients Who Are Found to Have Adrenal Cancer After Adrenalectomy [ Time Frame: Assessed at 6 months ]Patients who were tested for and found to have adrenal cancer after adrenalectomy.
- Proportion of Patients Who Were Diagnosed With Subclinical Hypercortisolism by Fluorodeoxyglucose (FDG) Positron Emission Tomography (PET)/Computed Tomography (CT) Scan [ Time Frame: Assessed at 6 months ]Proportion of patients who were diagnosed with subclinical hypercortisolism by FDG/PET/CT scan.
- To Determine the Optimal Diagnostic Test for Subclinical Hypercortisolism [ Time Frame: Assessed at 6 months ]An assessment of whether 1 mg dexamethasone suppression test, basal adrenocorticotropic hormone (ACTH), midnight salivary cortisol, or urinary free cortisol is the optimal test to diagnose patients with subclinical hypercortisolism.
- Proportion of Patients That Have Improvement in Quality of Life (QOL) After Adrenalectomy Compared to Medical Therapy [ Time Frame: Assessed at 6 months ]QOL questionnaires were provided to participants to assess well being pre and post operatively. Participants take a self-administered questionnaire to assess physical and mental health according to Cushing's Quality of Life Questionnaire. The score has a minimum of 12 and maximum of 60. A higher score indicates an improved quality of life.
- Proportion of Patients That Developed Deep Venous Thrombosis With Subclinical Hypercortisolism [ Time Frame: Assessed at 6 months ]Proportion of patients that developed deep venous thrombosis with subclinical hypercortisolism regardless of whether the participants received adrenalectomy or not.
- Correlation Between Dermal Thickness and Patients With Subclinical Hypercortisolism [ Time Frame: Assessed at 6 months ]A skin biopsy and skin ultrasound were done to measure the dermal layer of skin to look for a decrease in the thickness of skin as compared to normal values reported in the literature as measured in millimeters of thickness. Diagnostic sensitivity and changes in skin thickness were assessed.
