Brief summary

It is currently unclear if immediate curative treatment (radiotherapy or surgery) of high-risk prostate cancer without metastasis in older men (\>=75 years) generates the same survival benefits as in younger patients or if the harms/ side-effects of immediate curative treatment outweigh the benefits. In this study the investigators randomize older patients with high-risk, non-metastatic high-risk prostate cancer to either immediate curative therapy or to conservative, more problem-oriented therapy to investigate if immediate curative treatment prolongs life, improves quality of life and is cost-effective.

Detailed description

There is a lack of both level 1 evidence and consensus regarding the optimal treatment strategy for older men (\>=75 years) with non-metastatic, high-risk prostate cancer. Currently, in Scandinavia, the majority of older patients are treated conservatively, i.e. with hormone therapy or watchful waiting while some centers recommend immediate curative therapy regardless of patient age. Older patients thus risk both undertreatment and overtreatment of their cancer. This randomized clinical trial investigates if immediate curative therapy of high-risk, non-metastatic prostate cancer prolongs life (as it does in younger patients) and improves health-related quality of life. Furthermore, this trial investigates if the early side effects of immediate curative therapy are compensated by better long-term tumor control, better quality of life, functional status and improved survival.

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).

A high scale score represents a higher response level. Thus a high score for a functional scale represents a high / healthy level of functioning, a high score for the global health status / QoL represents a high QoL, but a high score for a symptom scale / item represents a high level of symptomatology / problems)

High scores indicate poor mobility, good family support, much worry about the future, good maintenance of autonomy and purpose)
