Can aggressive prostate cancer treatment extend life in men over 75?
NCT ID NCT05448547
First seen Sep 10, 2026 · Last updated Sep 11, 2026 · Updated 1 time
Summary
Researchers are testing whether immediate curative treatment (surgery or radiotherapy, with or without hormone therapy) helps men aged 75 and older with high-risk, non-metastatic prostate cancer live longer and with better quality of life compared to conservative, symptom-focused care. The trial enrolls 980 older men and randomly assigns them to one of the two approaches. The goal is to find out if the benefits of aggressive treatment outweigh the side effects in this age group.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- radiotherapy or surgery, with or without hormone therapy
- What this could lead to
- If it works, doctors could have clear evidence on whether to offer curative treatment to men over 75 with high-risk prostate cancer, potentially extending their lives.
- What could go wrong
- Curative treatment can cause urinary, bowel, and sexual side effects that may outweigh benefits in older men. The trial may show that conservative care is just as good for survival and quality of life.

Inclusion Criteria: 1. Participant must be 75 years of age or older, at the time of signing the informed consent. 2. Participants who are healthy as determined by medical evaluation and geriatric G8/ miniCOGTM evaluation (G8: Fit, score \>14, or reversibly frail; miniCOGTM: score \>2) And who have PCa (diagnosed ≤6 months) with one or both of the following features: * Gleason grade 8-10 (ISUP group 4 and 5) other than microscopic, low-volume disease (tumor must be either palpable or visible on MRI, i.e., PIRADS 4 or 5) * Locally advanced PCa (T3 or T4) (unequivocal findings of clinical/ radiological T3 or clinical/ radiological T4 on DRE or MRI; broad capsular contact of tumor on MRI is treated as localized disease, T2, in the context of this study) * Able to read, understand and fill in HRQoL questionnaires (PROMS) 3. Male 4. Capable of giving signed informed consent as described in Appendix 1, which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol. Exclusion Criteria: Medical Conditions 1. Dementia (unable to consent) Prior/Concomitant Therapy 2. Prior radiation to the pelvis 3. Hormone therapy \>3 months prior to randomization Diagnostic assessments 4. Lymph node metastasis (N0) on MRI, CT or PSMA-PET CT (equivocal N-findings =N0; borderline cases will be discussed and called by a study tumor board). 5. Distant metastasis (M0) on MRI, CT, bone scan or PSMA-PET CT (equivocal bone scan findings need to be confirmed with MRI or CT; borderline cases will be discussed by a study tumor board). Other Exclusions 6. Disabled or severe comorbidity (identified by G8 screening) 7. Unable to read, understand or fill out HRQoL questionnaires (PROMS)
