Treatment

The treatment you receive for a meningioma depends on many factors, including:

  • The size and location of your meningioma
  • The rate of growth or aggressiveness of the tumor
  • Your age and overall health
  • Your goals for treatment

Wait-and-see approach

Immediate treatment isn't necessary for everyone with a meningioma. A small, slow-growing meningioma that isn't causing signs or symptoms may not require treatment.

If the plan is not to undergo treatment for your meningioma, you'll likely have brain scans periodically to evaluate your meningioma and look for signs that it's growing.

If your doctor determines your meningioma is growing and needs to be treated, you have several treatment options.

Surgery

If your meningioma causes signs and symptoms or shows signs that it's growing, your doctor may recommend surgery.

Surgeons work to remove the meningioma completely. But because a meningioma may occur near many delicate structures in the brain or spinal cord, it isn't always possible to remove the entire tumor. In those cases, surgeons remove as much of the meningioma as possible.

The type of treatment, if any, you need after surgery depends on several factors.

  • If no visible tumor remains, then no further treatment may be necessary. However, you will have periodic follow-up scans.
  • If the tumor is benign and only a small piece remained, then your doctor may recommend periodic follow-up scans only. In some cases, small leftover tumors may be treated with a form of radiation treatment called stereotactic radiosurgery.
  • If the tumor is atypical or malignant, you'll likely need radiation.

Surgery may pose risks including infection and bleeding. The specific risks of your surgery will depend on where your meningioma is located. For instance, surgery to remove a meningioma that occurs around the optic nerve can lead to vision loss. Ask your surgeon about the specific risks of your surgery.

Radiation therapy

If your meningioma can't be completely removed surgically, your doctor may recommend radiation therapy following surgery.

The goal of radiation therapy is to destroy any remaining meningioma cells and reduce the chance that your meningioma may recur. Radiation therapy uses a large machine to aim high-powered energy beams at the tumor cells.

Advances in radiation therapy increase the dose of radiation to the meningioma while reducing radiation to healthy tissue. Radiation therapy options for meningiomas include:

  • Stereotactic radiosurgery (SRS) is a type of radiation treatment that aims several beams of powerful radiation at a precise point. Contrary to its name, radiosurgery doesn't involve scalpels or incisions. Radiosurgery typically is done in an outpatient setting in a few hours. Radiosurgery may be an option for people with meningiomas that can't be removed with conventional surgery or for meningiomas that recur despite treatment.
  • Fractionated stereotactic radiotherapy (SRT) delivers radiation in small fractions over time, such as one treatment a day for 30 days. This approach may be used for tumors too large for radiosurgery or those in an area that can't tolerate the high intensity of radiosurgery — such as near the optic nerve.
  • Intensity-modulated radiation therapy (IMRT) uses computer software to modify the intensity of radiation directed at the meningioma site. This may be used for meningiomas located near sensitive brain structures or those with a complex shape.
  • Proton beam radiation uses radioactive protons precisely targeted at the tumor, reducing damage to the surrounding tissue.

Drugs

Drug therapy (chemotherapy) is rarely used to treat meningiomas, but it may be used in cases that don't respond to surgery and radiation.

There isn't a widely accepted chemotherapy approach to the treatment of meningiomas, but researchers are currently studying molecularly targeted approaches.

Alternative medicine

Alternative medicine treatments can't treat meningiomas, but some may help provide relief from treatment side effects or help you cope with the stress of having a meningioma.

Alternative medicine therapies that may be helpful include:

  • Acupuncture
  • Hypnosis
  • Massage
  • Meditation
  • Music therapy
  • Relaxation exercises

Discuss options with your doctor.
