Can you treat a pituitary tumor with radiation?

Can you treat a pituitary tumor with radiation?

Radiation therapy can be used in one of several ways for pituitary tumors. It may be recommended after pituitary tumor surgery to prevent regrowth of a tumor. Radiation may also be used as the sole treatment if the tumor cannot be removed surgically, or if the tumor regrows after surgery.

What side effects can occur when treating a pituitary Macroadenoma with radiation therapy?

Some side effects of radiation therapy used for pituitary gland tumours are:

  • fatigue.
  • hair loss.
  • skin problems.
  • vision changes.
  • nausea and vomiting.
  • problems with memory or thinking.
  • less hormones made by the pituitary gland than normal (hypopituitarism)

Can pituitary Macroadenoma be treated without surgery?

Pituitary macroadenomas often require surgical intervention for cure. The exceptions to this rule are the macroprolactinomas, which usually have an excellent response to medical therapy.

How do you shrink a pituitary tumor?

Drugs called dopamine agonists can stop prolactinomas from making too much prolactin and shrink these tumors. Drugs are often the only treatment needed. Cabergoline (Dostinex) and bromocriptine (Parlodel) are most commonly used.

How successful is pituitary surgery?

The success rate is about 60% with growth-hormone secreting macroadenomas [2]. Some pituitary tumors remain surgically incurable due to invasion of the cavernous sinuses and other important structures.

Will I get my vision back after removing a pituitary tumor?

What to expect. For our patients with vision loss from pituitary adenoma, meningioma or craniopharyngioma, vision has been restored or improved in 75-80% of cases. Full recovery may occur within a few days of surgery but in some cases, improvement occurs slowly over 6-12 months post-surgery.

How long can you live with pituitary Macroadenoma?

The 5-year survival rate tells you what percent of people live at least 5 years after the tumor is found. 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 causes pituitary microadenoma?

As with adenomas elsewhere, the likely cause of pituitary microadenomas is a local mutation leading to autonomous growth and/or secretion. A variety of tumor suppressor genes and oncogenes have been described in sporadic pituitary tumorigenesis.

What is the recovery time from pituitary tumor removal?

For the first few weeks after surgery, you may feel tired, have a headache, or slight nasal congestion, but these symptoms should gradually improve. And within 2 weeks, you should be back to your normal daily activities, including work. Removing a pituitary tumor may cause abnormal hormone levels.

What is the prognosis for a pituitary tumor?

The prognosis for a pituitary tumor is generally good if the tumor and the hormones it may be secreting in excess and the destructive effects of the tumor on the endocrine function of the pituitary can be controlled.

What is the treatment for benign pituitary tumor?

Drug therapy to stop the tumor from making prolactin and to stop the tumor from growing.

  • Surgery to remove the tumor (transsphenoidal surgery or craniotomy) when the tumor does not respond to drug therapy or when the patient cannot take the drug.
  • Radiation therapy.
  • Surgery followed by radiation therapy.
