title: [The significance and limitation of prostate specific antigen in the mass screening for prostate cancer].
abstract: The ultimate aim of the mass screening program is to decrease the prostate cancer mortality, which can be demonstrated only in a well designed and well controlled trial comparing screened and unscreened populations. However, there are not any trials which prove the effectiveness of mass screening for prostate cancer. Among the 3 modalities, prostate specific antigen (PSA) had the highest sensitivity and positive predictive value. However, PSA had the 20% probability to diagnose incorrectly the patient with prostate cancer as a normal. PSA had 10% possibility to detect clinically insignificant cancer. It is important to inform subjects not only the significance but also limitation of mass screening by PSA.
