[Screening for prostate cancer: clinical significance and future perspectives].

The merits of introducing PSA-based screening would be cause-specific mortality reduction and prevention of developing metastatic disease, which was recently confirmed by prospective randomized controlled trials. On the other hand, some men participating in the screening program may be of drawbacks in terms of overdetection and overtreatment. Therefore, providing a fact sheet on screening for prostate cancer and also progress in an optimal screening system including more accurate cancer detection, minimally invasive treatment and active surveillance strategy, which can reduce overdetection, overtreatment, and loss of QOL due to treatment, would be very important.
