Patient handout: Spine SBRT (Stereotactic Radiotherapy)
Radiotherapy Step by Step โ Designed for radiation oncologists to use in clinic
An advanced technique delivering a high, very precise dose to a spine lesion while protecting the spinal cord.
Why radiotherapy is used
- Spine stereotactic radiotherapy is a very precise technique used for selected vertebral lesions, to control the tumor and relieve pain.
- It is distinguished by a high, focused dose in one or a few sessions, with a very sharp dose fall-off to protect the nearby spinal cord.
- It is not suitable for every patient; your doctor selects those who meet strict criteria.
The area being treated
- The specific affected vertebra or vertebrae, with careful avoidance of the spinal cord.
- The margin around the target is very small thanks to the precision of the technique.
- The spinal cord is defined with high precision as the most important organ to protect.
How to prepare
- Keep your precise imaging and planning appointments, as their quality is the basis of treatment safety.
- Report immediately any new weakness or numbness before or after treatment.
- Continue your painkillers, and expect a possible temporary pain flare after the session.
- Be careful of falls and excess strain on the back, and ask about any movement restrictions.
Early (acute) side effects
- A temporary pain flare after treatment in some patients โ expected and managed with painkillers or steroids when needed.
- Mild tiredness.
- Nausea or symptoms depending on the treated vertebral level (such as swallowing or stomach).
- Slight skin redness at times.
Questions to ask your doctor
- Why did you choose stereotactic treatment (SBRT) for my case specifically?
- How many sessions are expected?
- What is the risk of a vertebral fracture after treatment and how do we monitor it?
- What signs should I watch for and report immediately?
- Are there alternatives, and what are the pros and cons of each?
When to contact us immediately
- New or increasing weakness or numbness in the limbs, or difficulty controlling urination or bowels (emergency โ spinal cord compression)
- New sudden severe back pain (possible vertebral fracture)
- Fever or signs of infection
- Sudden loss of sensation or movement coordination
If any of these appear, contact your treatment team immediately or go to the emergency department.
