Post-Prostatectomy Linac-Based Ultrahypofractionated Radiotherapy for Patients With Localized Prostate Cancer
This study is for men who have had surgery for prostate cancer and might need more treatment because their cancer could return. Usually, this means many weeks of daily radiation, but this trial explores a new method called SBRT. SBRT uses very precise radiation over just five treatment sessions, instead of 30 or more. Researchers want to find out if this shorter, more convenient treatment is as safe and effective after prostate surgery as the longer traditional method. This is an important step because it could offer a much easier treatment experience for men needing further care.
At a glance
What is this study about?
When men have prostate cancer, surgery is a common way to treat it. However, for some men, there's a chance the cancer might return, especially if certain signs were found during or after the operation. We usually know the cancer might be coming back if a blood test called PSA starts to rise again. If this happens, doctors often suggest more treatment with radiotherapy to try and get rid of any remaining cancer cells.
Traditionally, this radiotherapy involves coming to the hospital for treatment five days a week, for about six to six and a half weeks – that's a lot of visits! But thanks to new, very accurate radiation machines, there's a different way called Stereotactic Body Radiotherapy (SBRT). SBRT can deliver a strong, targeted dose of radiation in just five sessions. We already know this shorter treatment can be safe and effective for men whose prostate is still in place, but we don't have much information yet for men who have already had their prostate removed.
This study aims to change that. Researchers want to see if SBRT is a safe and effective option for men who need radiotherapy after prostate surgery. By taking part, you could help us understand if this quicker treatment works just as well and has similar side effects to the longer traditional method, potentially making future treatment much easier for many men.
Key takeaways
- Exploring a new, shorter radiation treatment (SBRT) for prostate cancer after surgery.
- Aims to reduce the number of radiation sessions from 30+ to just 5.
- Focuses on men whose prostate cancer might be returning after an operation.
- Investigating safety and effectiveness compared to traditional radiotherapy.
- Could offer a more convenient treatment option in the future.
Who may be eligible?
This study is looking for men who have had surgery for prostate cancer. You might be able to join if your doctors have found signs that your cancer could return, such as specific findings from your operation or if your PSA blood test has started to rise after surgery. You also need to be well enough to complete questionnaires about your health.
There are some reasons why you wouldn't be able to join. For example, if your doctors believe there's still a large amount of cancer or if it has spread to your lymph nodes or other parts of your body. You also can't have had radiation treatment to your pelvis before, or if you have certain medical conditions that make radiation unsafe, like severe bowel problems or certain diseases affecting your joints and tissues. Having a hip replacement might also mean you can't take part.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Have you had surgery for prostate cancer?
- Has your doctor discussed that your prostate cancer might be returning (e.g., rising PSA)?
- Have you *not* had radiation treatment to your pelvis before?
- Do you *not* have other serious medical conditions that would make radiation unsafe (like severe inflammatory bowel disease)?
- Do you *not* have widespread cancer (e.g., in your lymph nodes or elsewhere)?
- Are you able and willing to fill out questionnaires about how you're feeling?
What does participation involve?
If you decide to take part, you'll first have a meeting where the study team will explain everything in detail and answer all your questions. If you agree, you'll sign consent forms. You'll have five SBRT treatment sessions, usually spread over about one to two weeks. Throughout the study, you'll be asked to complete some questionnaires about how you're feeling and any side effects you might be experiencing. You'll also have regular check-ups with the study team, including blood tests and examinations. The total duration of your participation, including follow-up, will be determined by the study protocol, but typically involves monitoring over several years to assess long-term effects.

Common questions
What is 'SBRT'?
SBRT stands for Stereotactic Body Radiotherapy. It's a very precise type of radiation that delivers high doses to the cancer area in fewer treatment sessions.
Why is this study important?
This study is important because it's looking for a shorter, more convenient way to give radiation treatment to men who've had prostate surgery, which could improve their quality of life.
Will I still get my usual care if I don't join?
Yes, absolutely. Your doctors will continue to give you the best possible care, whether or not you choose to take part in this research study.
What does a 'rising PSA' mean?
After prostate cancer surgery, if your PSA (Prostate-Specific Antigen) blood test starts to go up again, it can be a sign that some cancer cells might have returned.
How many treatments will I need?
If you join this study and receive SBRT, you'll have five radiation treatment sessions, usually over one to two weeks.
