Stereotactic Gamma Ray Surgery For Malignant Intracranial Tumors

What you should know

Stereotactic gamma ray surgery is used to treat tumors inside your head. Beams of radiation kill the tumor cells. Normal tissues near the tumor get little or no radiation. Malignant intracranial tumors are cancer cells that can grow anywhere inside your head. Cancer cells can spread to other parts of your body and grow into new tumors. Cancer cells from other parts of your body can also spread to your head and grow into a tumor.

Care Agreement

You have the right to help plan your care. Learn about your health condition and how it may be treated. Discuss treatment options with your caregivers to decide what care you want to receive. You always have the right to refuse treatment.

Risks

  • Radiation kills tumor cells but can also damage other normal cells in your head. Your brain, eyes, blood vessels, or nerves may get damaged during gamma ray treatments. You may have headaches, nausea, vomiting, seizures, or problems with your vision or memory. You may have alopecia, a condition that causes your hair to thin and fall out. Areas that make hormones may get damaged, and you may need medicines to replace these hormones. There is also a chance that your tumor may not completely shrink or that it may come back. In some cases, a new tumor may grow after this treatment.

  • Without treatment, malignant intracranial tumors may grow bigger and damage other tissues around them. The blood or nerve supply to nearby structures may be cut off. If this happens, you may have problems seeing, moving, speaking, breathing, or thinking clearly. This may lead to other serious medical problems, such as blindness, seizures, or stroke. Cancer cells can spread and grow into new tumors in other parts of your body.

Getting Ready

The week before your treatment:

  • Ask a family member or friend to drive you home after your treatment. Do not drive yourself home.

  • Bring your medicine bottles or a list of your medicines when you see your caregiver. Tell your caregiver if you are allergic to any medicine. Tell your caregiver if you use any herbs, food supplements, or over-the-counter medicine.

  • Ask your caregiver if you need to stop using aspirin or any other prescribed or over-the-counter medicine before your procedure or surgery.

  • You may need x-rays, a CT scan, or MRI to check the location, shape, and size of your tumor. Ask your caregiver for more information about these and other tests that you may need. Write down the date, time, and location of each test.

  • Write down the correct date, time, and location of your procedure.

The night before your treatment:

Ask caregivers about directions for eating and drinking.

The day of your treatment:

  • Ask your caregiver before you take any medicine on the day of your surgery. Bring a list of all the medicines you take, or your pill bottles, with you to the hospital. Caregivers will check that your medicines will not interact poorly with the medicine you need for surgery.

  • You or a close family member will be asked to sign a legal document called a consent form. It gives caregivers permission to do the procedure or surgery. It also explains the problems that may happen, and your choices. Make sure all your questions are answered before you sign this form.

Treatment

What will happen:

  • You will placed on a table that can be moved to different positions. Shields that block radiation from reaching other parts of your body may be put over you. A head frame will be used to hold your head very still during the treatment. You may get medicine to numb the area where the frame will be placed. The head frame will be secured with pins.

  • The table you are lying on will be moved inside the treatment hood. MRI or CT scans are used to help point the beams directly at your tumor. Your caregiver will set the shape of the beams and the amount of radiation your tumor will get. The beams will pass through your skull and brain and reach your tumor. You will need to lie still and relax during the treatment. After the treatment, the table will be moved out of the hood. The head frame and helmet will be removed.

After your treatment:

You will be taken to a room where caregivers will watch you closely for problems. Do not try to get out of bed until your caregiver says it is okay. Later, you will be taken to your hospital room, or you may be able to go home.

Contact a caregiver if

  • You have a fever.

  • You cannot make it to your treatment on time.

  • You have questions or concerns about your stereotactic gamma ray surgery.

Seek Care Immediately if

  • You had a seizure.

  • You suddenly have problems thinking or remembering.

  • You have sudden shortness of breath or chest pain.

  • Your arms or legs suddenly get weak, or you lose feeling in them.

  • Your headaches, seizures, or other symptoms get worse.
