Radiosurgery, or radiation therapy, may be used instead of or in addition to surgery to treat pituitary tumors. Your team will determine your specific treatment plan and if radiosurgery is the best option for you. 

When planning your treatment, we consider factors such as location and size of the tumor, your symptoms and your overall health.

Gamma Knife for Pituitary Tumors

Despite its name, Gamma Knife does not use a knife at all. It is a targeted treatment for pituitary tumors. During Gamma Knife treatment, we will:

  1. Fit you for a head frame. This helps us determine the location for the radiation treatment and keeps your head still during the procedure.
  2. Give you local anesthetic.
  3. Perform an MRI scan to determine the exact location of the treatment area. Together, our neuro-radiologist and radiation oncologist will plan the dose of radiation you need.
  4. Position you so that your head remains still and deliver the radiation beams to the predetermined location. You will be awake the entire time and can communicate with your team at any point.
  5. After the treatment, you will remain in the recovery room for a few hours, possibly overnight. By the next day, many patients are able to return to their normal activities.

Advantages of Gamma Knife for Pituitary Tumors

Gamma Knife treatments take much less time than regular radiation therapy. Due to the extreme precision of the radiation beam, we can use a much higher dose of radiation, so you require fewer treatments. The targeted beam is highly effective against the tumor while sparing the surrounding healthy structures in the brain. Other advantages include:

  • Relatively painless
  • Few side effects or complications
  • Quicker return to normal activities
