Abstract

BackgroundThe 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. ObjectiveTo describe initial participation rates and diagnostic outcomes. Design, setting, and participantsThe 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 analysisOverall and regional participation rates, PSA distributions, PI-RADS score distributions, cancer detection, and treatment were evaluated. Results and limitationsA 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. ConclusionsThe 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 summaryWe report the diagnostic outcomes of inviting 68 000 50-yr-old men to organised prostate cancer testing.
