    • After 11 years of follow-up, the European Randomized Study of Screening for Prostate Cancer (ERSPC) reported a 29% reduction in prostate-cancer mortality among men who underwent screening for prostate-specific antigen (PSA) levels. However, the extent to which harms to quality of life resulting from overdiagnosis and treatment counterbalance this benefit is uncertain.

  • Could Differences in Treatment Between Trial Arms Explain the Reduction in Prostate Cancer Mortality in the European Randomized Study of Screening for Prostate Cancer?

    • Differential treatment between trial arms has been suggested to bias prostate cancer (PC) mortality in the European Randomized Study of Screening for Prostate Cancer (ERSPC).To quantify the contribution of treatment differences to the observed PC mortality reduction between the screening arm (SA) and the control arm (CA).A total of 14 136 men with PC (SA: 7310; CA: 6826) in the core age group (55-69yr) at 16yr of follow-up.The outcomes measurements were observed and estimated numbers of PC deaths by treatment allocation in the SA and CA, respectively. Primary treatment allocation was modeled using multinomial logistic regression adjusting for center, age, year, prostate-specific antigen, grade group, and tumor-node-metastasis stage. For each treatment, logistic regression models were fitted for risk of PC death, separately for the SA and CA, and using the same covariates as for the treatment allocation model. Treatment probabilities were multiplied by estimated PC death risks for each treatment based on one arm, and then summed and compared with the observed number of deaths.The difference between the observed and estimated treatment distributions (hormonal therapy, radical prostatectomy, radiotherapy, and active surveillance/watchful waiting) in the two arms ranged from -3.3% to 3.3%. These figures, which represent the part of the treatment differences between arms that cannot be explained by clinicopathological differences, are small compared with the observed differences between arms that ranged between 7.2% and 10.1%. The difference between the observed and estimated numbers of PC deaths among men with PC was 0.05% (95% confidence interval [CI] -0.1%, 0.2%) when applying the CA model to the SA, had the two groups received identical primary treatment, given their clinical characteristics. When instead applying the SA model to the CA, the difference was, as expected, very similar-0.01% (95% CI -0.3%, 0.2%). Consistency of the results of the models demonstrates the robustness of the modeling approach. As the observed difference between trial arms was 4.2%, our findings suggest that differential treatment explains only a trivial proportion of the main findings of ERSPC. A limitation of the study is that only data on primary treatment were available.Use of prostate-specific antigen remains the predominant explanation for the reduction in PC mortality seen in the ERSPC trial and is not attributable to differential treatment between trial arms.This study shows that prostate cancer deaths in the European screening trial (European Randomized Study of Screening for Prostate Cancer) were prevented because men were diagnosed and treated earlier through prostate-specific antigen screening, and not because of different, or better, treatment in the screening arm compared with the control arm.

  • No excess mortality after prostate biopsy: results from the European Randomized Study of Screening for Prostate Cancer.

    • Study Type - Harm (RCT)
Level of Evidence 1b OBJECTIVES: To assess possible excess mortality associated with prostate biopsy among screening participants of the European Randomized Study of Screening for Prostate Cancer (ERSPC). SUBJECTS AND METHODS: From three centres in the ERSPC (Finland, The Netherlands and Sweden) 50 194 screened men aged 50.2-78.4 years were prospectively followed. A cohort of 12 959 first-time screening-positive men (i.e. with biopsy indication) was compared with another cohort of 37 235 first-time screening-negative men. Overall mortality rates (i.e. other cause than prostate cancer mortality) were calculated and the 120-day and 1-year cumulative mortality were calculated by the Kaplan-Meier method, with a log-rank test for statistical significance. Incidence rate ratios (RR) and statistical significance were evaluated using Poisson regression analyses, adjusting for age, total PSA level, screening centre and whether a biopsy indication was present, or whether a biopsy was actually performed or not. RESULTS: There was no statistically significant difference in cumulative 120-day other cause mortality between the two groups of men: 0.24% (95% CI, 0.17-0.34) for screening-positive men vs 0.24% (95% CI, 0.20-0.30) for screening-negative men (P= 0.96). This implied no excess mortality for screening-positive men. Screening-positive men who were not biopsied (n= 1238) had a more than fourfold risk of other cause mortality during the first 120 days compared to screening-negative men: RR, 4.52 (95% CI, 2.63-7.74) (P < 0.001), adjusted for age, whereas men who were actually biopsied (n= 11 721) had half the risk: RR, 0.41 (95% CI, 0.23-0.73) (P= 0.002), adjusted for age. Only 14/31 (45%) of the screening-positive men who died within 120 days were biopsied and none died as an obvious complication to the biopsy. CONCLUSIONS: Prostate biopsy is not associated with excess mortality and fatal complications appear to be very rare.

  • Toward an Optimal Interval for Prostate Cancer Screening.
  • 2012

    • BACKGROUND: The rate of decrease in advanced cancers is an estimate for determining prostate cancer (PCa) screening program effectiveness. OBJECTIVE: Assess the effectiveness of PCa screening programs using a 2- or 4-yr screening interval. DESIGN, SETTING, AND PARTICIPANTS: Men aged 55-64 yr were participants at two centers of the European Randomized Study of Screening for Prostate Cancer: Gothenburg, Sweden (2-yr screening interval, n=4202), and Rotterdam, the Netherlands (4-yr screening interval, n=13 301). We followed participants until the date of PCa, the date of death, or the last follow-up at December 31, 2008, or up to a maximum of 12 yr after initial screening. Potentially life-threatening (advanced) cancer was defined as cancer with at least one of following characteristics: clinical stage ≥T3a, M1, or N1; serum prostate-specific antigen (PSA) >20.0 ng/ml; or Gleason score ≥8 at biopsy. INTERVENTION: We compared the proportional total (advanced) cancer incidence (screen-detected and interval cases), defined as the ratio of the observed number of (advanced) cancers to the expected numbers of (advanced) cancers based on the control arm of the study. MEASUREMENTS: The proportional cancer incidence from the second screening round until the end of observation was compared using a 2- or 4-yr screening interval. RESULTS AND LIMITATIONS: From screening round 2 until the end of observation, the proportional cancer incidence was 3.64 in Gothenburg and 3.08 in Rotterdam (relative risk [RR]: 1.18; 95% confidence interval [CI], 1.04-1.33; p=0.009). The proportional advanced cancer incidence was 0.40 in Gothenburg and 0.69 in Rotterdam (RR: 0.57; 95% CI, 0.33-0.99; p=0.048); the RR for detection of low-risk PCa was 1.46 (95% CI, 1.25-1.71; p<0.001). This study was limited by the assumption that PSA testing in the control arm was similar in both centers. CONCLUSIONS: A 2-yr screening interval significantly reduced the incidence of advanced PCa; however, the 2-yr interval increased the overall risk of being diagnosed with (low-risk) PCa compared with a 4-yr interval in men aged 55-64 yr. Individualized screening algorithms must be improved to provide the strategy for this issue.
