摘要 目的探讨血清总前列腺特异性抗原(T-PSA)、游离前列腺特异性抗原(F-PSA)和F-PSA/T-PSA比值(F/T)对前列腺癌的诊断和临床意义。方法应用全自动化学发光分析仪检测健康对照组(60例),前列腺增生组(BPH组,49例)及前列腺癌组(PCa组,28例)血清T-PSA、F-PSA含量,计算F-PSA/T-PSA比值,分析T-PSA、F-PSA/T-PSA不同取值水平对临床诊断前列腺癌的灵敏度、特异性及诊断准确性的影响。结果 PCa组和BPH组的血清总前列腺特异性抗原、游离前列腺特异性抗原含量都比健康对照组高,差异具有统计学意义(P<0.05),PCa组的F-PSA、T-PSA含量高于BPH组,而F/T却比BPH组低许多,差异具有统计学意义(P<0.05)。结论 T-PSA界值取4 ng/ml,F/T取<0.16能有效地筛检前列腺癌,在鉴别前列腺癌与前列腺增生中有重要的临床应用价值。
