Bringing proton beam therapy centres to the UK
The UK’s first NHS high-energy proton beam therapy centre opened at The Christie Hospital in 2018. The University of Manchester’s research was vital in helping to bring this technology to the UK, enabling more patients to access proton therapy for some of the most difficult-to-treat cancers.
- Before 2018, no high-energy NHS proton therapy treatment facilities existed in the UK.
- Creating a UK treatment centre has saved the NHS £60,000 per patient.
- The research is used in public engagement campaigns to raise awareness of proton therapy.
Costly international treatment
Proton beam therapy (PBT) improves the targeting of radiotherapy, meaning fewer side effects, faster recovery and better outcomes for patients. It also allows tumours that are difficult to treat by more conventional means (for example those lying close to sensitive critical organs) to be targeted.
Proton therapy is particularly suited to children as the reduced radiation dose to the healthy tissue means there is less chance of radiation-induced secondary cancers later in life.
Before 2018, no high-energy NHS proton therapy treatment facilities existed in the UK; around 200 NHS patients were sent abroad for PBT treatment every year, at a cost to the health service of more than £100,000 per patient. Having to travel to receive treatment meant patients were often parted from most of their family and support systems, while certain patients were excluded altogether because they were unable to travel, often because they were too ill.

Providing treatment in the UK
The UK’s first high-energy proton beam therapy centre opened at The Christie Hospital in Manchester in November 2018.
Research from the University helped to define the centre specifications, including an in-depth analysis of the one-accelerator/three-treatment-room set-up. The key to ensuring the cost-effectiveness of proton therapy is avoiding an overestimation of the number of patients a system could treat (this issue has led to problems in many centres developed overseas).
Our research identified which equipment parameters were important to allow the highest possible patient throughput for the very complex indications being treated.
The University worked with the procurement team to estimate the throughput of patients with the technology offered by vendors. Offering treatment in the UK has saved the NHS at least £60,000 per patient.
More importantly, it has increased the number of patients treated, as at least 10% of patients now treated at The Christie’s PBT centre would have been ineligible for treatment abroad.
Since it opened, more than 550 patients have been treated at the facility.
Technologically advanced and future-proofed
University researchers formulated the section of the specification that evaluated key beam parameters of the systems offered by vendors.
Our research helped to define the bespoke system specifications needed to ensure the treatment centre was flexible and future-proof, allowing the NHS to offer state-of-the-art treatments.
For example, the PBT centre:
- uses complex gantries allowing proton beams to be delivered through a full 360 degrees around the patient, optimising the dose to the tumour while sparing healthy tissue;
- uses the very latest spot scanning technology to precisely deliver the prescribed dose to the tumour;
- is developing new technologies so that tumours can be treated in organs which move during treatment.
One in five patients treated at The Christie PBT centre would not have received the same quality of treatment at other centres abroad, because they do not have the same state-of-the-art technology.
Integrating research in a real-world setting
“Our research is exploring how we can best use proton therapy for patients, making their treatment even more effective. It’s all about the patients; that’s who we’re doing it for.”

The University of Manchester
A £6 million dedicated research facility has been built within the PBT centre, funded by The Christie Charity and developed in partnership between the University and The Christie Hospital.
More than 30 researchers work at the research facility – headed by Karen Kirkby, Professor of Proton Therapy Physics – and focus on the scientific and technological challenges of PBT.
The team is closely linked with the clinical teams at The Christie to ensure that research remains relevant and can be translated into innovative treatments for UK patients more easily in the future.
Beyond the clinical setting, the team’s research is used to support public engagement and awareness.
Previous projects have included creating patient information leaflets with UK charity Brainstrust; working with the Parliamentary Office of Science and Technology to produce a leaflet on proton therapy; and supporting the Science and Industry Museum with its Cancer Revolution Exhibition.
Next-generation radiotherapy treatment
In 2021, Manchester researchers used PBT to demonstrate the potential of a new type of radiotherapy called FLASH. This delivers the radiation dose up to 1,000 times faster than conventional radiotherapy.
FLASH is thought to be capable of reducing damage to normal tissue to an even greater degree, therefore reducing side effects while still suppressing tumour growth.
If FLASH delivers on its potential, it could mean faster treatments with fewer side effects, helping patients return to normal life earlier.
