Population-based Organised Prostate Cancer Testing: Results from the First Invitation of 50-year-old Men

• Background: The European Union recently recommended evaluation of the feasibility of organised prostate cancer screening. In Sweden, regional population-based organised prostate cancer testing (OPT) programmes were introduced in 2020. Objective: To describe initial participation rates and diagnostic outcomes. Design, setting, and participants: The three most populated Swedish regions invited all men aged 50 yr to OPT by a letter in 2020–2022. Men with prostate-specific antigen (PSA) ≥3 ng/ml were referred for prostate magnetic resonance imaging (MRI). PSA assays differed across regions. Men with Prostate Imaging Reporting and Data System (PI-RADS) 1–3 and PSA density ≥0.15 ng/ml/cm3 or PI-RADS 4–5 were referred for a biopsy. Data were obtained from the Swedish Register for Organised Prostate Cancer Testing. Outcome measurements and statistical analysis: Overall and regional participation rates, PSA distributions, PI-RADS score distributions, cancer detection, and treatment were evaluated. Results and limitations: A total of 23 855 (35%) of 68 060 invited men participated; 696 (2.9%) had PSA ≥3 ng/ml, and of them, 306 (44%) had a biopsy indication and 221 (32%) had a biopsy. On biopsy, 93 (42%) had Gleason grade group ≥2 (0.39% of PSA-tested men) and 44 (20%) Gleason grade group 1 cancer. Most men with cancer had treatment with curative intent (70%) or were under active surveillance (28%). Across regions, proportions of men with PSA ≥3 ng/ml ranged from 2.3% to 4.0%, and those with PI-RADS score 4–5 ranged from 12% to 21%. A limitation is that results are applicable only to first testing of men in their early 50s. Conclusions: The OPT programmes are feasible with good compliance to the diagnostic pathway. The use of MRI and PSA density avoided a biopsy for over half of the men with PSA ≥3 ng/ml. Inter-regional differences in diagnostic outcomes show a need for standardisation of the diagnostic pathway's components. Patient summary: We report the diagnostic outcomes of inviting 68 000 50-yr-old men to organised prostate cancer testing.
