Intervention-related Deaths in the European Randomized Study of Screening for Prostate Cancer

• Background: Identification of intervention-related deaths is important for an accurate assessment of the ratio of benefit to harm in screening trials. Objective: To investigate intervention-related deaths by study arm in the European Randomized Study of Prostate Cancer Screening (ERSPC). Design, setting, and participants: ERSPC is a multicenter trial initiated in the 1990s to investigate whether screening on the basis of prostate-specific antigen (PSA) can decrease prostate cancer mortality. The present study included men in the core age group (55-69 yr: screening group n = 112 553, control group n = 128 681) with 16-yr follow-up. Outcome measurements and statistical analysis: Causes of death among men with prostate cancer in ERSPC were predominantly evaluated by independent national committees via review of medical records according to a predefined algorithm. Intervention-related deaths were defined as deaths caused by complications during the screening procedure, treatment, or follow-up. Descriptive statistics were used for the results. Results and limitations: In total, 34 deaths were determined to be intervention-related, of which 21 were in the screening arm and 13 in the control arm. The overall risk of intervention-related death was 1.41 (95% confidence interval 0.99-1.99) per 10 000 randomized men for both arms combined and varied among centers from 0 to 7.0 per 10 000 randomized men. A limitation of this study is that differences in procedures among centers decreased the comparability of the results. Conclusions: Intervention-related deaths were rare in ERSPC. Monitoring of intervention-related deaths in screening trials is important for assessment of harms. Patient summary: We investigated deaths due to screening or treatment to assess harm in a trial of prostate cancer screening. Few such deaths were identified. (c) 2021 The Author(s).
