title: [PSA-screening for prostate cancer--yes or no?].
abstract: Prostate cancer is a mayor health care problem, especially in the industrialised countries of the Western world. At this time it is the second most common cancer reason for death (CH: 1500 men/year) which will even get more importance in the future by demographic developments. While there is no doubt that in individuals early detection of organ confined disease with localised treatment the prostate cancer can be eradicated and individual men be cured there are uncertainties whether mass screening a population will contribute to reducing prostate cancer related mortality. Its value has not been proved definitively by prospective randomised controlled studies. Most of Medical Societies recommend a "well informed" decision by family physicians, where the men between 50-70 years know about the benefits and harms including: risk of cancer, diagnostic procedures, therapeutic consequences and possible side effects. After agreement of early detection a biopsy has to be done directly above a PSA level of 4.0 ng/ml or a suspicious digital rectal examination. A PSA "grey zone" 4-10 ng/ml can not further be postulated. The ratio of free/total PSA gives no support to prolong biopsy in this moment, because an elevated benign prostate with a higher production of free PSA can mask the tumor in the peripheral zone. Results of the ERSPC and the PLCO trials are expected to give information about the benefits and harms of mass screening in 2006/8.
