Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is an expansion of the screening-by-invitation STHLM3MRI trial for detection of prostate cancer. In summary, we assess longterm outcomes (prostate cancer mortality, incidence and resource use) in men (i) invited and randomized to a screening program using PSA, a biomarker test and MRI; (ii) invited and randomized to a single PSA test with prostate biopsies followed by opportunistic testing and (iii) population controls. Mortality is verified through register data, disease verification is made through in-study biopsy results and registry data.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Organized screening including repeat testing (MRI+biomarkers)

participants are offered prostate cancer screening. Interventions are (i) a paired PSA and Stockholm3 bloodtest; (ii) if elevated (PSA\>=3 \| Stockholm3\>=0.11), an MRI is offered. If MRI shows PI-RADS≥3, prostate biopsies are offered. Screenings are offered at year 0, year 2-3 (if original PSA≥1.5) and year 6

Group Type EXPERIMENTAL

PSA/Stockholm3/MRI

Intervention Type DIAGNOSTIC_TEST

Stockholm3+PSA followed by MRI of the prostate

One-time invitation to testing arm (traditional biopsies)

participants are offered prostate cancer screening. interventions are a PSA bloodtest. If PSA≥3 ng/ml, a standard prostate biopsy is offered. No repeat screenings are offered.

Group Type ACTIVE_COMPARATOR

PSA

Intervention Type DIAGNOSTIC_TEST

PSA followed by standard biopsies

Population controls

Population controls are identified through registers and followed in national outcome registers (Swedish Board of Health and Welfare)

Group Type NO_INTERVENTION

No interventions assigned to this group
