To accurately position the patient and deliver radiation to a well-defined malignant tumor, stereotactic radiation therapy, or SRT, is a type of external radiation therapy. With SRT, the entire radiation dose is split up into multiple doses that are administered over a few days. When treating brain tumors and other brain illnesses, stereotactic radiation therapy is usually utilized as part of a comprehensive treatment regimen.

Even though SRT's overall dose may be higher than SRS's, each day's dose administration will be substantially lower. Known as stereotactic ablative body radiation (SABR) or stereotactic body radiation therapy (SBRT), both are used to treat localized cancers in the brain and, more recently, in the body.

The excessive dose administered in SRS and SRT requires the patient to be positioned very precisely. For each patient, a customized mask or positioning device is created at the moment of CT imaging to achieve this. This makes it possible to precisely position the patient, facilitating the sub-millimeter radiation administration.

What are the types of SRT?

A variety of devices are employed in the delivery of stereotactic radiotherapy, such as:

Linear Accelerators (LINAC)- These devices target the tumor with high-energy electrons or X-rays.
CyberKnife- A robotic radiosurgery system with sub-millimeter accuracy that can deliver radiation from different directions.
Gamma Knife- Targets brain or head and neck cancers with concentrated gamma radiation beams.

SRT is commonly used to treat tumors of small to intermediate size in the pancreas, brain, spine, lung, liver, prostate, and other body areas. It works especially well for tumors that are hard to operate on because of their location or the patient's general health.

Stereotactic radiation (SRT) is applied to treat unusual growths or small tumours in the spine, liver, prostate, brain, lungs, or other body areas. It shields the surrounding healthy tissues from the tumour while accurately delivering high doses of radiation. When surgery is not safe or feasible, particularly for hard-to-reach tumours, SRT is often used. While the tumour is not taken out at once, it damages the cells, and in the long run, it kills them.

You should see a radiation oncologist or cancer specialist if you’ve been diagnosed with a tumor that may not be treatable with regular surgery. SRT may be considered if the tumor is small and well-defined. After SRT, contact your doctor right away if you experience severe headaches, dizziness, seizures, shortness of breath, or weakness.

Before treatment, your doctor will review your medical history and run imaging tests like CT, MRI, or PET scans to locate the tumor. You may need a special mask or body frame made to keep you still during treatment. No surgery or anesthesia is required, but you may need to stop some medications or follow eating instructions before treatment. Your doctor will explain the process and side effects.

Imaging: High-resolution scans are used to plan the exact location and shape of the tumor.
Positioning: You lie on a table with your head or body held still using a custom-made device.
Radiation delivery: A machine aims focused radiation beams at the tumor from different angles.
No cutting or pain: The treatment is non-invasive and doesn’t require any cuts or anesthesia.
Single or multiple sessions: You may receive SRT in 1 to 5 sessions depending on the tumor type.

Each session lasts 30 minutes to 1 hour. Most patients are done in a few days to a week.

Possible side effects depend on the area treated. Common issues include fatigue, headaches, nausea, skin redness, or swelling. Rarely, there may be nerve damage, radiation injury to nearby organs, or swelling in the brain or lungs. Most side effects go away on their own or with medication.

SRT allows for high-precision treatment with fewer sessions and less damage to healthy tissue. It's painless, outpatient-based, and recovery is quick. It can shrink or destroy tumors without needing open surgery, making it ideal for people who are not surgical candidates.

Since there’s no actual surgery, you can usually go home the same day. Mild side effects like tiredness or swelling may last a few days to weeks. Your doctor will schedule follow-up scans to monitor the tumor. Most people return to normal activities within a day or two.

SRT has a high success rate, especially for small and early-stage tumors. It controls or shrinks tumors in over 85–95% of cases, depending on the tumor type and location. Many patients experience long-term tumor control with minimal side effects.
