Prostate-specific antigen (PSA) blood testing is likely to reduce the risk of death from prostate cancer, found a new review published on Thursday by an influential international science research organization — a shift in medical evidence that could encourage wider use.
The Cochrane review’s first author, Juan Franco from Heinrich Heine University Düsseldorf in Germany, said at a press conference that they have “moderate certainty” that the screening test, which identifies high levels of PSA as a potential marker of prostate cancer, leads to a reduction in disease-specific deaths. The benefits are marginal: The review analyzed results from six trials involving 800,000 participants conducted in Europe and North America, and found about two fewer prostate cancer deaths for every 1,000 men screened.
