What hormone is secreted by the pituitary adenoma?

Approximately half of pituitary adenomas secrete distinct pituitary hormones (most often prolactin, growth hormone, or adrenocorticotropic hormone). While these tumors are histologically benign, they have potent endocrine effects that lead to significant morbidity and shortened lifespan.

What endocrine gland is most affected by an ACTH secreting pituitary adenoma?

The excess ACTH produced by the pituitary tumor stimulates the adrenal to secrete excess cortisol. Adenomas are benign, or non-cancerous, tumors of the pituitary gland which can secrete increased amounts of ACTH. Women are affected 5 times as often as men.

What does a pituitary adenoma produce?

Some pituitary adenomas secrete one or more hormones in excess. Even when they are small in size, these endocrine-active pituitary tumors can cause hormonal imbalances that affect body functions. People can develop pituitary adenomas at any age.

What tumors can produce ACTH?

Tumors that can, in rare cases, release ACTH include:

• Benign carcinoid tumors of the lung.
• Islet cell tumors of the pancreas.
• Medullary carcinoma of the thyroid.
• Small cell tumors of the lung.
• Tumors of the thymus gland.

How long can you live with a pituitary tumor?

The 5-year survival rate for people with a pituitary gland tumor is 97%. Survival rates depend on the type of tumor, the person’s age, and other factors.

What are the symptoms of high ACTH?

Symptoms may include:

• Upper body obesity.
• Round face.
• Increased fat around neck or a fatty hump between the shoulders.
• Thinning arms and legs.
• Fragile and thin skin.
• Stretch marks on abdomen, thighs, buttocks, arms, and breasts.
• Bone and muscle weakness.
• Severe fatigue.

How is the adrenal gland affected by an ACTH secreting pituitary adenoma?

When a pituitary tumor secretes too much ACTH (adrenocorticotropic hormone), it causes the otherwise normal adrenal glands to produce too much cortisol. This type of Cushing’s syndrome is termed Cushing’s disease, and it is diagnosed just like other endocrine disorders (by measuring hormone production).

How is high ACTH treated?

Radiation therapy, which is administered over a six-week period to the pituitary gland, has yielded improvement in 40-50 percent of adults and up to 85 percent of children. Stereotactic radiosurgery has also been found to be an effective treatment for patients with ACTH-secreting pituitary adenomas.

Can you live a full life with a pituitary tumor?

In general, when a pituitary tumor is not cured, people live out their lives but may have to deal with problems caused by the tumor or its treatment, such as vision problems or hormone levels that are too high or too low.

How long can you live with pituitary adenoma?

Percent means how many out of 100. The 5-year survival rate for people with a pituitary gland tumor is 97%. Survival rates depend on the type of tumor, the person’s age, and other factors.

What is the prognosis of pituitary macroadenomas?

Microadenomas do not cause excess mortality. These tumors generally are too small to cause pain, diplopia, or pressure on the optic chiasm. Otherwise-normal anterior and posterior pituitary function remains intact. Any morbidity is caused by excessive hormone secretionor patient anxiety.

How common are pituitary adenomas?

Pituitary macroadenomas are the most common cause of hypopituitarism. While pituitary adenomas are common, affecting approximately one in 6 of the general population, clinically active pituitary adenomas that require surgical treatment are more rare, affecting approximately one in 1000 of the general population.

What is the treatment for pituitary tumor?

Treatments for pituitary tumors include surgical removal of the tumor; radiation therapy, using high-doses of x-rays to kill tumor cells; and/or drug therapy, using certain medications to block the pituitary gland from producing too many hormones. The most common treatment is surgery.

What are the symptoms of the pituitary gland?

Your pituitary gland is involved in a range of things, so any condition involving it can produce a diverse set of symptoms. Make an appointment with your doctor if you regularly notice: headaches. weakness or fatigue. high blood pressure. unexplained weight gain. trouble sleeping.
