摘要 目的探讨血清总前列腺特异抗原(tPSA)、游离前列腺特异抗原(fPSA)与tPSA比值(f/tPSA)诊断前列腺癌(PCa)的临床应用价值。方法清晨空腹抽静脉血,采用美国BECKMAN公司180SE ACCESS微粒子全自动化学发光分析仪及配套试剂,测定患者血清中的tPSA和fPSA,并计算(f/tPSA)比值。结果以tPSA〉4ng/ml为临界诊断值,对PCa诊断的灵敏度为98%,特异度为41.6%,在诊断灰区(4ng/ml≤tPSA≤20ng/ml),PCa与良性前列腺增生(BPH)两组患者间tPSA差异无统计学意义(P〉0.05),而f/tPSA比值PCa组明显低于BPH组,两组间差异有统计学意义(P〈0.01)。结论单纯以tPSA诊断PCa灵敏度高,但特异度不高,应用f/tPSA比值能明显提高诊断PCa的特异性。
