Bone (non-spine) SBRT

What happens in planning?

For planning, a team of radiation therapists will give you a CT scan in the same position that you will be in for treatment. This CT scan is used to make your treatment plan.

You will be placed in a position lying on your back, using equipment that will help keep you very still. The equipment used will depend on the location of your bone that we are treating (see pictures below). This equipment may put pressure on your chest, stomach or legs. It is important that you breathe normally throughout the CT and stay as still as possible.

The length of your treatment will be much longer than the CT scan. Please let us know if you are not comfortable so we can help find you a position that you can stay still in.

To make sure you are in the same position for every treatment, the radiation therapists will make tattoos on your skin that will last forever. These are small tattoos, the size of a mole or freckle, that are made with a needle.

Treatment appointments

You will get your appointment times for treatments at the end of your planning appointment. Bone SBRT treatment is usually given once per day for 2-5 days. We may not be able to schedule your treatments at the time that you ask for, as we have many patients that need to be booked in for treatment.

On your first day of treatment, please check in at the radiation reception on the Ground Floor of T Wing in the Odette Cancer Centre (blue circle on the map). A team of radiation therapists will give you your SBRT treatment.

You will be asked to change into a gown so the radiation therapists can see the tattoos on your skin. Once you are in the right position, the treatment machine (see picture below) will move around you to take an image. The machine may come close to your body, but will never touch you. This image lets us know that you are in the right position for treatment.

How long do treatments take?

Your treatment will last about 30 minutes. It is important that you stay still and breathe normally. You will not see or feel anything while the radiation is on. Your team of radiation therapists can see and hear you at all times.

Most patients can drive themselves to and from treatment. You will be at the Cancer Centre for about 60-90 minutes for each treatment. A member of your SBRT treatment team will see you at least once during your treatment to see how you feel and to arrange follow-up.

Side effects may differ from person to person based on their general health and the area of the body that is being treated. Many people have no side effects during or after treatment.

Possible side effects during treatment include:

• Fatigue or tiredness (most common)
• An increase in pain (your doctor may prescribe you medication to prevent this)
• Nausea or upset stomach (your doctor may prescribe you medication to prevent this
• Diarrhea

It can take 4-6 weeks after your treatment is finished to recover from treatment-related side effects.
