目的　探讨前列腺癌集团检诊对临床前列腺癌诊断的影响。　方法　总结 1996至2 0 0 1年集团检诊发现的 67例前列腺癌和 1986至 2 0 0 1年长春各大医院诊治的 3 58例前列腺癌患者资料 ,从年度及年龄分布、临床分期、血清前列腺特异性抗原 (PSA)含量、病理分级和治疗等方面进行对比分析。　结果　 1999至 2 0 0 1年 3年间年均确诊例数较 1986至 1989年增长 4.7倍。其中集团组B期以下早期癌占 58.2 % ,临床组只占 2 7.9% ,且多为偶发癌 ;转移癌的诊断率集团组低于临床组 ;临床组PSA≥ 2 0ng/ml的比率高于集团组 ,低分化癌的比率高于集团组 ,差异均有统计学意义。集团组行前列腺癌根治术的比率较临床组提高了 15.3 %。　结论　集团检诊可以真正揭示国人前列腺癌的发病现状 ,可明显增加临床前列腺癌特别是早期癌的诊断例数 ,是实现前列腺癌早期诊断与治疗的最佳途径 Objective To investigate the influence of prostate cancer clinics on the diagnosis of clinical prostate cancer. Methods The data of 67 cases of prostate cancer diagnosed by the Group from 1996 to 2001 and 388 cases of prostate cancer treated in major hospitals of Changchun from 1986 to 2001 from 1996 to 2001 were summarized. The data were collected from the year and age distribution, clinical stage, serum Prostate-specific antigen (PSA) content, pathological grading and treatment of comparative analysis. Results The average number of cases diagnosed in the three years from 1999 to 2001 increased 4.7 times from 1986 to 1989. Among them, group B had 58.2% of patients with early stage B cancer and only 7.97% of patients with clinical stage B, and most of them were incidental cancers. The diagnosis rate of metastatic cancer was lower in clinical group than in clinical group. The ratio of PSA≥20ng / ml was higher in clinical group Group group, the proportion of poorly differentiated cancer than the group, the differences were statistically significant. Group radical prostatectomy ratio was 15.3% more than the clinical group. Conclusion The group examination can truly reveal the incidence of prostate cancer in Chinese people and can significantly increase the number of cases diagnosed with clinical prostate cancer, especially early cancer, which is the best way to achieve early diagnosis and treatment of prostate cancer
