Is There a Treatment for Cushing’s Disease?

Cushing’s disease is an important hormonal disorder that causes higher-than-normal levels of cortisol in the body for a prolonged period. It usually occurs due to a small tumor in the pituitary gland that secretes the ACTH hormone. Excessive secretion of ACTH stimulates the adrenal glands, resulting in increased cortisol production. Prolonged high cortisol levels can lead to various problems such as weight gain, rounding of the face, muscle weakness, purple stretch marks on the skin, high blood pressure, elevated blood sugar, and bone loss.

One of the most common questions asked by people diagnosed with Cushing’s disease is, “Is there a treatment for Cushing’s disease?” Today, there are various effective treatment options available for Cushing’s disease. When the underlying cause of the disease is eliminated, cortisol levels can be brought under control and remission can be achieved. However, the treatment method is not the same for every patient. The size and location of the tumor, the level of hormone production, previous treatments, and the patient’s overall health condition are determining factors in treatment decisions.

Prof. Dr. Ömür Günaldı is involved in specialist evaluations that emphasize the importance of accurate diagnosis and individualized treatment planning in pituitary-related disorders such as Cushing’s disease.

Can Cushing’s Disease Be Treated?

Yes. Cushing’s disease can be treated, and the disease may go into remission in appropriate patients. The aim is not only to reduce symptoms but also to eliminate the source causing excess cortisol or control the effects of cortisol on the body.

The Endocrine Society recommends removing the underlying tumor in endogenous Cushing’s syndrome and considering various second-line treatments when surgery is not possible or is insufficient. In pituitary-related Cushing’s disease, transsphenoidal surgery performed by an experienced pituitary surgeon is the primary treatment approach.

Therefore, a person diagnosed with Cushing’s disease should not assume that the condition will remain untreated. Today, surgery, medication treatments, radiotherapy, and, in certain special cases, different surgical options can be used.

What Is the First Treatment Option for Cushing’s Disease?

For appropriate patients with pituitary-related Cushing’s disease, the first choice is generally surgery targeting the tumor. The aim of surgery is to eliminate the ACTH-secreting pituitary tumor and thereby stop excessive cortisol production.

This surgery is usually performed using the transsphenoidal surgical approach. The pituitary region is accessed through the nose and sinuses. This allows the pituitary tumor to be treated without the need for a large incision through the upper part of the skull.

The Endocrine Society defines selective transsphenoidal removal of the adenoma by an experienced pituitary surgeon as the optimal treatment for Cushing’s disease.

Surgery performed by experienced surgeons, particularly for small pituitary tumors, has been reported to achieve high remission rates. However, because the characteristics of each patient’s tumor are different, surgical success may vary from person to person.

Can Cushing’s Disease Be Treated Without Surgery?

In some patients, treatment options other than surgery may be used. However, surgery is the primary treatment method for most suitable patients with pituitary-related Cushing’s disease.

When surgery is not possible, when the disease persists after surgery, or when the disease recurs, options such as medication treatment and radiotherapy may be considered. Treatment decisions should be made by a multidisciplinary team according to the individual characteristics of the patient.

Therefore, the belief that “if I cannot undergo surgery, I cannot be treated” is not correct. Non-surgical options may help control high cortisol levels and aim to reduce the health problems caused by the disease.

Medication Treatment for Cushing’s Disease

Some medications used in the treatment of Cushing’s disease aim to reduce cortisol production, while others aim to block the effects of cortisol in the body.

Medication treatments may be considered particularly in patients whose cortisol levels remain elevated after surgery or who are not suitable candidates for surgery. Some medications reduce cortisol production in the adrenal glands, while others may target pituitary ACTH production. Medications that block the effects of cortisol may also be used in certain groups of patients.

Medication options that may be used for Cushing’s disease, when considered appropriate by a physician, include ketoconazole, metyrapone, osilodrostat, pasireotide, cabergoline, and, in certain situations, mifepristone. Each medication has different indications, side effects, and monitoring requirements.

Therefore, medication treatment must be administered under specialist supervision. Because excessively low cortisol levels can also cause serious health problems, regular hormone monitoring during treatment is important.

Is Radiotherapy Used in Cushing’s Disease?

In Cushing’s disease, radiotherapy or stereotactic radiosurgery may be a treatment option for some patients. Radiotherapy may be considered particularly when tumor tissue remains after pituitary surgery or when the disease recurs.

The effects of radiotherapy may not appear as quickly as those of surgery. Therefore, medication may be used to keep cortisol levels under control while waiting for the effects of treatment to develop. The Endocrine Society also recommends evaluating whether cortisol can be controlled with medication before radiotherapy.

The decision regarding whether radiotherapy is appropriate is made by evaluating the location and size of the tumor, previous surgery, hormone levels, and the patient’s overall condition.

Can Cushing’s Surgery Be Performed a Second Time?

If the disease cannot be controlled with the first surgery, a second transsphenoidal surgery may be considered in some patients. A second surgery may be among the treatment options, particularly if the tumor is thought not to have been completely removed during the first operation or if imaging reveals a pituitary lesion suitable for repeat surgery.

However, the decision regarding a second surgery should be evaluated more carefully than the first operation. The condition of the anatomical structures in the pituitary region, the results of the previous surgery, and the location of the tumor are important factors.

Therefore, the decision regarding a second surgery should be made through a joint evaluation by an experienced pituitary surgeon and an endocrinologist.

Are the Adrenal Glands Removed in Cushing’s Disease?

In certain severe and selected cases, surgical removal of both adrenal glands, known as bilateral adrenalectomy, may be one of the treatment options. However, this approach is not used for every patient with Cushing’s disease.

It may be considered particularly when other treatments have not been sufficient, when urgent control of the disease is necessary, or in certain specific ACTH-related conditions. Because the body’s natural cortisol production is eliminated after bilateral adrenalectomy, lifelong hormone replacement therapy and regular follow-up are required.

Therefore, adrenalectomy is an important treatment method used in selected patients.

When Do Symptoms Improve After Cushing’s Treatment?

With successful treatment, elevated cortisol levels can be brought under control. However, symptoms may not disappear completely immediately.

It may take time for the body to return to normal after prolonged exposure to high cortisol levels. Weight gain, muscle weakness, skin changes, decreased bone density, and psychological symptoms may improve over time.

For example, a decrease in cortisol levels after surgery may be a positive development, but during this period, it may take time for the adrenal glands to resume normal cortisol production. Therefore, temporary glucocorticoid replacement therapy may be necessary in some patients.

Prof. Dr. Ömür Günaldı draws attention to the need for a comprehensive approach in which not only the patient’s hormone levels but also other health problems caused by prolonged high cortisol levels are monitored after treatment.

Can Cushing’s Disease Recur?

Cushing’s disease may recur after successful treatment. Therefore, achieving remission does not mean that follow-up should be completely discontinued.

After treatment, cortisol and other necessary hormone tests may be performed at intervals determined by the doctor. Clinical symptoms are also monitored. The Endocrine Society recommends regular evaluation for recurrence after treatment in ACTH-dependent Cushing’s syndrome.

If the disease recurs, options such as repeat surgery, medication treatment, or radiotherapy may be considered according to the patient’s condition.

Treatment of Associated Conditions in Cushing’s Disease

Reducing cortisol levels alone is not sufficient in the treatment of Cushing’s disease. Health problems that may result from prolonged excess cortisol must also be monitored.

These may include:

• High blood pressure
• Elevated blood sugar and diabetes
• Bone loss and osteoporosis
• Muscle weakness
• Cardiovascular disease risks
• Mental and psychological problems
• Increased susceptibility to infections
• Abnormal blood lipid levels

The Endocrine Society recommends treating and providing long-term follow-up for cortisol-related associated conditions in patients with Cushing’s syndrome.

What Happens If Cushing’s Disease Treatment Is Successful?

The primary goal of successful treatment is to eliminate or control excess cortisol. As cortisol levels return to normal, many symptoms associated with Cushing’s disease may gradually improve.

Weight control may become easier, muscle strength may recover, and blood pressure and blood sugar may become easier to control. However, the speed of recovery varies from person to person.

Some effects may take weeks or months to improve. In particular, problems associated with prolonged high cortisol levels, such as impaired bone health and muscle loss, may take longer to recover.

Regular medical follow-up is extremely important throughout this process.

Why Is a Specialist Team Important in the Treatment of Cushing’s Disease?

Cushing’s disease is not a simple condition involving only one organ. Because of the relationship between the pituitary gland, adrenal glands, and hormonal system, it is important for the diagnosis and treatment process to be managed by an experienced team.

The Endocrine Society also recommends a multidisciplinary approach involving an experienced endocrinologist in Cushing’s syndrome and recommends that patients be informed about their treatment options.

In patients with Cushing’s disease evaluated by Prof. Dr. Ömür Günaldı, identifying the source of the disease, evaluating hormone levels, and selecting the appropriate treatment method are also important stages of the process.

Is There a Treatment for Cushing’s Disease?

Yes, there is a treatment for Cushing’s disease. Today, surgery, medication treatment, radiotherapy, and, in selected cases, different surgical methods can be used to bring the disease under control and achieve remission in appropriate patients.

In pituitary-related Cushing’s disease, the first choice in appropriate patients is generally the removal of the ACTH-producing tumor through transsphenoidal surgery. When surgery does not provide sufficient results or is not possible, medication treatment, radiotherapy, repeat surgery, and other options may be considered according to the individual characteristics of the patient.

After treatment, the patient needs regular follow-up, cortisol levels must be monitored, and health problems caused by high cortisol levels must be brought under control. Although Cushing’s disease is a treatable condition, the treatment process differs for each patient.

Prof. Dr. Ömür Günaldı plays an important role in the evaluation process with a specialist approach that emphasizes accurate diagnosis, identification of the source of the disease, and individualized treatment planning in Cushing
