GAMMA KNIFE for BRAIN METASTSES
Gamma Knife radiosurgery has become a preferred option for treating complex and “inoperable” tumors. It is often used as an alternative to surgery and/or whole brain radiation and — in some cases — is combined with those treatments.
While Gamma Knife was originally applied to patients with only a single brain metastasis as an alternative to craniotomy and removal (flowed by whole brain radiation therapy or WBRT), evidence indicates that disease control is possible in more than 80% of patients who undergo Gamma Knife radiosurgery alone for metastatic brain cancer.
The key to the success of Gamma Knife is its ability to accurately focus many beams of high-intensity gamma radiation to converge on one or more tumors. Each individual beam is relatively low energy, so the radiation has virtually no affect on healthy brain tissue.
THE ADVANTAGES OF GAMMA KNIFE
- Noninvasive – Despite its name, there is no knife. It’s called Gamma Knife because of the surgical precision and effectiveness. However, there’s no incision, no blood and no complications that occur with surgery.
- Proven – Studies show that local control—meaning the specific tumor treated does not come back—exceeds an average of 85% for the management of tumors in any brain location.
- High Dose of Evidence – Over 2,500 medical papers have been published on Gamma Knife surgery, and 800,000 patients have been treated worldwide. Other types of radiation treatment often claim to be as accurate and effective, but they don’t have the data and proven results of Gamma Knife.
- Accurate – There is no other radiation treatment system as precise and accurate as Gamma Knife.
- One treatment – The noninvasive Gamma Knife can isolate and deliver a high dose of radiation to one or more locations in the brain during a single treatment session.
- Fast recovery – Most people leave the hospital the same day and resume normal activities.
- Minimal side effects – Few people experience of a mild headache, which can be treated with an over-the-counter pain reliever. There is no loss of hair or nausea, as with some treatments.
- Flexible – Because it’s noninvasive, Gamma Knife can be used to treat tumors or other disorders in surgically inaccessible areas of the brain, such as the brain stem.
- Repeatable – Patients who develop new or growth of an existing tumor can be treated again with Gamma Knife.
WHY DOESN’T EVERYONE USE GAMMA KNIFE?
Not everyone is a candidate for Gamma Knife surgery. Additionally not all surgeons have been trained in its use or have access to a Gamma Knife system, so they may be reluctant to recommend it to patients.
