That’s the controversial question behind two large, randomized clinical trials this past year studying the relationship between PSA-based screening and prostate cancer mortality: The European Randomized Study of Screening for Prostate Cancer and the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial in the U.S. According to the European study, which involved over 162,000 men between the ages of 50 and 74 in seven countries, PSA-based screening reduced the already low rate of death from prostate cancer by 20%, but was also associated with a high risk of overdiagnosis and overtreatment.
The American PLCO trial found the rate of death from prostate cancer was very low for both the 38,343 men in the group that received annual PSA-based screening and the 38,350 men in the control group who received “usual care.” The conclusion:
