Radiation Treatment

Stereotactic Radiosurgery

(SRS)

Stereotactic radiosurgery, or SRS, is a very precise form of radiation therapy that uses multiple radiation beams to treat tumors in the brain. It offers a less invasive and safer alternative to brain surgery. Despite the name, SRS isn’t surgery at all in the sense that there are no incisions. Instead, SRS uses 3D imaging and high doses of radiation to target specific areas. This helps minimize the impact of the radiation on anything other than the tumor.

There are two methods that SRS might use to deliver radiation treatment:

  • Linear accelerator or LINAC machines treat tumors using X-rays. This usually involves a single session for smaller tumors or three to five sessions for larger tumors.
  • Gamma Knife machines use around 200 small gamma rays to target tumors. These machines are less common and are usually used for small- to medium-sized tumors.

Cancers SRS Treats

SRS is most often used to treat brain tumors, such as meningioma, paraganglioma, and others. It may also be an option for cancers that have spread to the brain from other parts of the body (referred to as brain metastases).

Because SRS is less invasive than other treatments, it can be used on hard-to-reach areas of the body, including those near vital organs.

Additionally, SRS can treat other abnormalities in and near the brain, like arteriovenous malformations (AVM), trigeminal neuralgia, and pituitary tumors.

SRS vs. SRBT

SRS is one type of Stereotactic Body Radiotherapy, or SBRT. SRS generally refers to SBRT that is used specifically on tumors in the brain or spine. SRS relies on additional technologies like IGRT (Image-Guided Radiation Therapy) to confirm the size and location of the tumor before, and sometimes during, treatment. This makes SRS more accurate than it would be otherwise.

How SRS Treatment Works

SRS works by using radiation to damage the DNA of the targeted cancer cells. The radiation, delivered in multiple small beams, causes the cells to lose the ability to reproduce, slowing the growth of the tumor and causing it to shrink. SRS can involve anywhere from one to five sessions, depending on the location of the cancer. Your doctor will let you know what to expect for your treatment situation.

The high level of precision built into SRS treatment helps minimize damage to healthy tissue surrounding the tumor. It also tends to significantly lower the risk of long-term side effects of stereotactic radiosurgery.

Your treatment will likely take place in an outpatient center and will include preparation for the procedure, the treatment itself, and a period of observation afterward. You will lie on a table, similar to what’s used for an MRI or CT scan. The treatment will involve several doses of X-rays delivered by your care team. This should be painless.

Afterward, you will move to a recovery area to make sure you’re feeling well enough to go home. You will need to bring someone with you to provide transportation and any other help you need after the procedure.

You should be able to return to your regular activities within a day. You will continue to be monitored with CT and/or MRI scans afterward.

Long-Term Side Effects of Stereotactic Radiosurgery

If you experience side effects after treatment, they are likely to be temporary, thanks to the efficiency and effectiveness of SRS. These might include things like fatigue, skin irritation, or hair loss.

Long-term side effects do happen in some cases, however, so it’s important to keep in touch and let us know if you notice anything unusual after your treatment. We will continue monitoring for things like changes in the brain and spinal cord, discomfort in the joints, and bone fractures.
