BackgroundEvidence from randomized trials on the effects of screening for prostate cancer (PCa) on disease-specific mortality accumulates slowly with increasing follow-up.ObjectiveTo assess data on PCa-specific mortality in the Rotterdam section of the European Randomized Study of Screening for Prostate Cancer (ERSPC) trial.Design, Setting, And ParticipantsA randomized controlled trial with randomization after signed, written informed consent (efficacy trial). In the period 1993-1999, a total of 42 376 men aged 54-74 yr were randomized to a screening arm (S-arm) (n = 21 210 with screening every 4 yr, applying a total prostate-specific antigen [PSA] level cut-off ≥ 3.0 ng/ml as biopsy indication) or a control arm (C-arm) (n = 21 166; no intervention).Outcome Measurements And Statistical AnalysisNumber of PCas detected per arm depicted by predefined time periods and prognostic groups. PCa-specific mortality analyses using Poisson regression in age group 55-74 yr at randomization and separately in the predefined age group of 55-69 yr.Results And LimitationsAfter a median follow-up of 12.8 yr, 19 765 men (94.2%) were screened at least once and 2674 PCas were detected (of which 561 [21.0%] were interval PCas). In the C-arm, 1430 PCas were detected, resulting in an excess incidence of 59 PCas per 1000 men randomized (61 PCas per 1000 in age group 55-69 yr). Thirty-two percent of all men randomized have died. PCa-specific mortality relative-risk (RR) reductions of 20.0% overall (age: 55-74 yr; p = 0.042) and 31.6% (age: 55-69 yr; p = 0.004) were found. A 14.1% increase was found in men aged 70-74 yr (not statistically significant). Absolute PCa mortality was 1.8 per 1000 men randomized (2.6 per 1000 men randomized in age group 55-69 yr). The number needed to invite and number needed to manage were 565 and 33, respectively, for age group 55-74 yr, and 392 and 24, respectively, for age group 65-69 yr. Given the slow natural history of the disease, follow-up might be too short.ConclusionsSystematic PSA-based screening reduced PCa-specific mortality by 32% in the age range of 55-69 yr. The roughly twofold higher incidence in the S-arm underlines the importance of tools to better identify those men who would benefit from screening.Copyright © 2013 European Association of Urology.
