Abstract:
Objective To investigate the influence of t he mass screening on the diagnostic status of the conventional ordinary prostati c cancer (CaP). Methods Sixty seven cases of prostate ca ncer detected by mass screening (January 1996～December 2001) and 358 cases diag n osed at the outpatient of various hospitals in Changchun (January 1986～December 2001) were compared in terms of age distribution,clinical stages,level of serum prostate special antigen(PSA),pathological grade and treatment modalities,with a SPSS analysis system. Results The annual average incide nce of CaP 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 A and B accounted for 58.2%. In the clinical group, it was only 27.9%,and mostly detected incident ally.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 c linical group.These differences were statistically significant.The cases of radi cal prostatectomy in the screening group increased 15.3% compared with that of t he clinical group. Conclusions Only the mass screening c an really reveal the actual prevalence of prostate cancer.It can markedly raise the number of prostate cancer,especially the cancer in the early stage.The mass screening is inevitable to detect the curable early stage prostate cancer.
