What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published

Summary

Researchers are testing whether a five-fraction course of stereotactic body radiotherapy (SBRT) works as well as the standard 20-fraction radiotherapy for men who need radiation after prostate cancer surgery. The trial enrolls 206 adults and randomly assigns them to either the short SBRT course or the standard course. The main goal is to compare urinary and bowel quality of life over two years, with follow-up for up to five years.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
stereotactic body radiotherapy (SBRT) to the prostate bed
What this could lead to
If SBRT works as well as standard radiotherapy, men could finish treatment in about a week instead of four weeks with similar urinary and bowel side effects.
What could go wrong
The trial is still testing whether the shorter course is safe and effective. SBRT may cause more urinary or bowel problems than standard treatment, and the results may not apply to all patients.

Inclusion Criteria: * Confirmed prostate cancer treated with radical prostatectomy (≥ 6 months since radical prostatectomy) * Indication for adjuvant or salvage radiotherapy (e.g. persisting or rising PSA, macroscopic recurrence, R1 resection, pT3b) at the discretion of the treating physician * Androgen deprivation therapy allowed at the discretion of the treating physician * WHO performance status 0-1 * Age ≥ 18 years * Indication for treatment of the locoregional lymphatic drainage at the discretion of the treating physician allowed (not mandatory) * Personally signed and dated written informed consent Exclusion Criteria: * Inability to follow the procedures of the study (e.g. due to language problems, psychological disorders, dementia) * Comorbidities which predispose to significant radiotherapy toxicities (e.g. inflammatory bowel disease), at the discretion of the treating physician * Prior radiotherapy to the intended treatment site * Presence of distant metastases (M1a is not an exclusion criterion)
