To enable pooled analyses of continuing and planned randomised trials of prostate cancer screening, guidelines for minimal data required for such analyses were developed in the recent meeting of the International Prostate Screening Trial Evaluation Group (IPSTEG). The aim of the pooled analysis with data on individual level will be: (a) Estimation of the effect of screening on prostate cancer mortality with greater precision than individual studies (b) Assessment of optimal screening procedures and interval (c) Identification of subgroups within the populations that might receive most benefit from screening (d) Evaluation of the quality of life effects and cost effectiveness of screening. All studies included in the combined analysis share a common core protocol with minimum data requirements. The protocol allows, however, adaptation of the procedures to local circumstances within defined options. It should be noted that the process is continuing and the protocol is subject to evaluation and revision in the meetings of the IPSTEG on a regular basis.

    • "The PLCO trial was also initiated in 1993 and has included approximately 74,000 men, randomized to the prostate arm of the trial. Conditions for a possible common analysis of ERSPC and PLCO trial have been discussed [4]. The ongoing randomized trials will not produce results for several years [5]. "

    ABSTRACT: ObjectivesOngoing randomized controlled screening trials for prostate cancer have not shown a beneficial effect on prostate cancer mortality reduction yet. A large number of observational (non-randomized) studies on prostate cancer screening have been published with contradictory outcome. This paper reviews the current case-control studies.MethodsSeven case-control studies of screening for prostate cancer were identified in a PubMed search, published from 1991 onwards, all conducted in North America. The screening test was either digital rectal examination (DRE) alone or in combination with PSA.ResultsOne DRE case-control study, found a significant preventive effect, whereas two others showed no effect of DRE screening on prostate cancer mortality nor on the occurrence of metastatic disease. Conflicting results were also observed in the studies assessing the effect of PSA/DRE. Only one study showed a significant 27% mortality reduction in the White male cohort, but found no effects in Blacks. The most recent study showed that screening with PSA/DRE was not protective in reducing prostate cancer mortality.ConclusionsOur review of the case-control studies does not indicate a benefit of prostate cancer screening. An answer has to come from the ERSPC trial, in Europe, and the PLCO trial, in the US, of which the outcomes are expected in 2007–2010.
