Find out about radioactive strontium (Strontium 89), which is a type of internal radiotherapy.
What radioactive strontium is
Radioactive strontium is a radioactive form of the metal strontium (Strontium 89). It has the brand name Metastron.
Radioactive strontium is sometimes used to treat cancers that have spread to the bones, most commonly prostate cancer.
If there are cancer cells in more than one area of bone, radioactive strontium can work well to treat those areas and reduce pain.
How you have radioactive strontium treatment
You have radioactive strontium as an injection into the vein. It might need to be repeated every 3 to 6 months.
You have the treatment as an outpatient and can go home afterwards.
The radioactive strontium is taken up by the cancer cells in the bone, and gives a high dose of radiotherapy to those areas.
Possible side effects of radioactive strontium
There are no immediate side effects from the injection. You have some radioactivity in your body for a while after treatment. But the total amount is extremely small and gets lower each day.
You might feel slightly more pain in the areas in the areas of cancer in your bone for a few days. Your doctor or nurse can give you advice on adjusting your painkillers if this happens.
The treatment can sometimes cause anaemia after a few weeks, so you need to have regular blood tests after the treatment.
Safety precautions for radioactive strontium
Your doctor or specialist nurse let you know if there are any safety guidelines you need to follow after your treatment, and how long you need to follow them for.
During the first week after your injection, low levels of radioactive strontium may be present in your blood and urine. So for 1 week you need to follow the guidelines below so that other people are not exposed to the radiation. These include:
- men should sit on a toilet if possible rather than using a urinal when passing urine
- flush toilets twice after use
- wipe up any spilled urine with a tissue and flush it away
- make sure you always wash your hands after using the toilet
- wash any linen or clothes that become stained with urine, straight away
- wash the clothes separately from other clothes and rinse them well
- ask your doctor or nurse for safety advice if you use any product to collect urine
- wash away any blood down a sink if you cut yourself
