This trial is looking at for people with breast cancer. It is for people who have an increased risk of developing long term heart problems years after radiotherapy.
After having surgery to remove your cancer, you might have radiotherapy to the breast, chest or armpit. This is to lower the risk of the cancer coming back.
There are short term and long term side effects of radiotherapy for breast cancer. Short term side effects include skin changes and tiredness. Long term side effects include changes to the breast or chest tissues. One long term side effect for a very small number of people is heart problems.
Health care practitioners can estimate who might develop these heart problems. To do this they look at your radiotherapy planning scan together with other factors such as your age and medical history. They then work out your potential lifetime risk. You are able to take part in this trial if your lifetime risk is likely to be increased. It’s important to point out that this possible risk is still very small.
The for breast cancer uses x-rays. This is the most targeted radiotherapy available for this cancer type.
Proton beam therapy is a type of radiotherapy that uses high energy protons. The radiotherapy team can plan this treatment to a specific depth.
Researchers think proton beam might be better at targeting the breast, chest and armpit, as well as reducing the dose of radiotherapy to your heart. They also want to make sure that there are no more shorter term side effects to the breast and chest, such as skin changes.
In this trial half the people will have standard radiotherapy and the other half will have proton beam therapy. The researchers will compare the 2 groups.
The aims of the trial are to:
The following bullet points are a summary of the entry conditions for this trial. Talk to your doctor or the trial team if you are unsure about any of these. They will be able to advise you.
Who can take part
You may be able to join this trial if all of the following apply. You:
Who can’t take part
You cannot join this trial if any of these apply. You:
This is a phase 3 trial. The trial team need 192 people to take part.
It is a randomised trial. A computer will put you into 1 of 2 treatment groups. The 2 groups are:
Everyone has a planning appointment before starting treatment. This appointment includes a scan. This is to work out your dose of radiotherapy and the exact treatment area.
Both groups have treatment every day Monday to Friday for 3 weeks.
Standard radiotherapy
You have treatment at your local radiotherapy centre.
Proton beam therapy group
You have treatment at either The Christie NHS Foundation Trust in Manchester or the University College Hospital in London. The NHS can arrange accommodation for you and your partner or carer during your treatment. A member of the team will tell you more about this when you join the trial.
You do not have to stay in the accommodation if, for example, you live close to the NHS proton centre. You might prefer to return home every day following your treatment.
Before proton beam therapy, you have a to plan your treatment area.
Samples for research
You can give a blood sample during the trial. Where possible your team take this when you have blood taken as part of your routine care.
The team ask for a piece of the tissue sample () taken when you were first diagnosed or from your surgery.
These samples are optional. You don’t have to agree to either of these if you don’t want to.
Researchers use these samples to find out more about breast cancer.
Quality of life
You fill in questionnaires:
The questions ask about:
These are quality of life questionnaires.
You see the doctor before taking part. This is to:
You see a member of the healthcare team once a week during treatment. This is to see how you are and to ask about side effects.
After treatment you see someone at 2 weeks and 3 weeks. If you still have side effects, you continue to see the doctor until you have only 1 side effect or none.
Depending on your hospital these may be face to face or by phone or video.
You then see them at:
At 2 years you have a CT scan as part of the trial.
The trial team monitor you during treatment and afterwards. Contact your advice line or tell your radiotherapy healthcare team if any side effects are bad or not getting better.

Please note: In order to join a trial you will need to discuss it with your doctor, unless otherwise specified.
