NCT03423303

Brief Summary

A population-based randomised trial of prostate cancer screening will be carried out. A total of approximately 117,200 men aged 50-63 in Helsinki and Tampere are randomised to intervention (screening) or control arm. A reduction in harms of screening in the form of overdiagnosis is sought, while retaining as much as possible of the mortality benefit (reduction in prostate cancer mortality). Novel methods that have been shown to increase specificity for clinically relevant prostate cancer but never tested in a randomised setting will be employed in screening and diagnostics. The main end-point is prostate cancer mortality at 10 and 15 years of follow-up.

Outcome Measures

Primary Outcomes (1)

  • Prostate cancer (PrCa) mortality

    An intention to screen analysis will be performed, with all men in the groups defined by random allocation, regardless of compliance. Follow-up starts at randomisation, and ends at death. Cox regression will be used with prostate cancer death as the outcome.

    At 10 years of follow-up.

Secondary Outcomes (3)

  • Prostate cancer (PrCa) mortality - secondary analysis

    At 10 years of follow-up.

  • Cumulative incidence of advanced (T3-T4 or M1) prostate cancer

    At approximately 5 years of follow-up.

  • Cumulative incidence of low-risk cancer (Gleason<7)

    At approximately 5 years of follow-up.

Other Outcomes (7)

  • Analysis of screening test performance - 4Kscore

    At 2, 4, and 6 years.

  • Analysis of screening test performance - MRI

    At 2, 4, and 6 years.

  • Assessment of health-related quality of life in men with prostate cancer

    At 4 years.

  • +4 more other outcomes

Study Arms (2)

Screening arm

EXPERIMENTAL

Invitation to prostate cancer screening and questionnaires.

Diagnostic Test: Prostate cancer screening

Control arm

NO INTERVENTION

Registry-based follow-up and a questionnaire.

Interventions

Depending on each diagnostic test result the participants in the screening arm will undergo PSA-testing, 4Kscore determination, MRI, and MRI/US fusion biopsy only.
