摘　　要：Objective To investigate the influence of the mass screening on the status of the prostate cancer （PCa）, we compared the cases of PCa detected by the mass screening and the cases diagnosed at a conventional ordinary urologic outpatient. Methods Using a SPSS analysis system, We compared 67 cases of prostate cancer detected by mass screening and 358 cases diagnosed at the outpatient of various hospitals in Changchun in terms of age distribution, clinical stages, level of serum prostate special antigen （PSA）, pathological stage and treatment modality. Results The annual average incidence of PCa during 1999 to 2001 increased 4.72 times when compared to the 1986 to 1989＇s. In the screening group, the cases with clinical stage T2 and T1 accounted for 59.7%. In the clinical group, it was only 28.0%, and mostly detected incidentally. Furthermore, in the screening group the percentage of the cases beyond 20 ng/ml PSA and of poorly differentiated carcinoma were much lower compared to the clinical group. These differences between them were statistically significant. The number of radical prostatectomy in the screening group increased 15.3% compared with that of the clinical group. Conclusion Only the mass screening can really reveal the actual prevalence of prostate cancer. It can markedly raise the number of prostate cancer, especially the cancer in the early stage.
