Methods: The serum PSA of 4 848 males over 50-years old for serum PSA was evaluated,respectively out of them 33 cases diagnosed as prostate cancer(screening group) were compared in terms of age distribution,level of PSA,clinical stages,Gleason score and treatment modalities with 28 patients in our hospital(clinical group). Results: In the screening group,the positive percentage account for 9.5%(PSA≥4 ng/ml) and the PCa positive rate was 6.8‰(33/4 848).The average age of the patients(73.2?8.0) was insignificant different between these two groups.The percentage of the cases beyond 20 ng/ml PSA in the screening group was significantly lower than that in clinical group,with 42.4% and 71.5% respectively.Furthermore,the cases with clinical stage A+B accounted for 69.7% in the screening group,while it was 35.7% in the clinical group(P
