The aim of this study is to clarify the usefulness of PSA screening to detect prostate cancer subclinically in Tokushima City. Mass screening of serum PSA measurement only was started from ２００２ in Tokushima City. Three years’ results are reported and analyzed in this paper.
In ２００２ to ２００４，（９０９９，９３４５，１０６８０） men over ５５ years old were measured serum PSA level with annual check of health condition at various outpatient clinics in Tokushima City. The men with high PSA levels were recommended to visit the urologist for further examinations. By the urologists the men with high PSA levels were diagnosed by careful urologic procedures including DRE, TRUS, accurate prostatic biopsy and more.
In （８０１，６０６，７２７） men, PSA levels were over normal range, and （４５５，２５７，３５８） men visited urologic clinics for further examinations. Careful examinations were performed and prostatic biopsies were done in （２３３，１２１，１４１） men. Finally, the prostate cancers were found out in （１２１，６０，５９） men and these men were entered suitable medical treatments immediately. Accordingly， （１．３４％，０．６４％，０．５５％） of （９０９９，９３４５，１０６８０） men with PSA measurements were diagnosed as prostate cancers. In the group of prostate cancer, patient number of early cancer group （Stage B） were （８０：６６．１％，４２：７０．０％，５０：８４．７％），which means that prostate cancers found out by PSA screening might be early curable cancers in many cases.
These ３ years’ results indicate that PSA screening is a very useful modality to find out early prostate cancers and contribute the decrease of prostate cancer death in Tokushima City in the future.
