Sarcoma UK Proton Beam Therapy Factsheet

Proton beam therapy is a type of radiotherapy that uses high-energy proton beams rather than high-energy radiation beams to deliver a dose of radiotherapy.

It can be used to treat different types of cancer including some types of sarcoma

For most patients there is no strong evidence that PBT is better than x-ray radiotherapy in treating sarcoma. For a lot of sarcoma patients x-ray radiotherapy may be just as or more effective to treat their type of cancer. PBT uses highly specialised and expensive equipment so it is important to prioritise this treatment for people who will most benefit from it. The current evidence suggests that proton beam therapy is unlikely to cure more people than current radiotherapy techniques. To find out which patients could benefit most, and who should be offered PBT as their standard treatment, we need data from clinical trials. Current research is taking place to find out how best to use PBT.

We have a factsheet on proton beam therapy which explains more about PBT including who is eligible for this treatment and how you can access this treatment overseas.
