摘要 目的 探讨游离前列腺特异性抗原(fPSA)与总前列腺特异性抗原(tPSA)比值在前列腺癌(PCa)鉴别诊断中的意义.方法 采用电化学免疫发光技术对86例前列腺良性增生(BPH)45例PCa患者和60例健康男性体检者(正常对照组)血清fPA和tPSA同时进行测定,并计算出fPSA/tPSA,进行统计分析.结果 BPH、PCa组tPSA水平明显高于正常对照组(P<0.05).PCa组和BPH组的血清tPSA差异亦有统计学意义,但当tPSA在4.0~10.0 μg/L范围时,PCa组血清fPSA/tPSA比值却明显低于BPH组(P<0.01).把fPSA/tPSA比值划分成8个区间,当fPSA/tPSA比值15%作为诊断灰区PCa诊断的临界值时,诊断的敏感性、特异性、阳性预测值、阴性预测值及正确诊断指数分别为72.8%、67.5%、62.5%、82.2%、50.2%.结论 当血清tPSA处于诊断灰区时,联合检测fPSA/tPSA比值可明显提高tPSA对PCa早期诊断的特异性.
