摘要 目的探讨血浆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与T-PSA比值(F/T)对前列腺癌(PCa)和良性前列腺增生(BPH)的诊断和鉴别诊断的意义。方法用美国雅培公司的i2000SR全自动化学发光免疫分析仪和微粒子酶免疫分析法(MEAI)分别检测经临床确诊的31例PCa、127例BPH患者及100例健康体检者血浆T-PSA、F-PSA,并计算F/T。结果 PCa组和BPH组的T-PSA、F-PSA及F/T差异均有统计学意义,PCa组和BPH组分别有4例和32例T-PSA测定值在4.0-10.0 ng/mL范围内,且T-PSA、F-PSA在两组之间无显著性差异,但F/T差异有统计学意义。结论 T-PSA、F-PSA及F/T等是诊断和鉴别诊断PCa和BPH的很好指标,但当T-PSA在4.0-10.0 ng/mL范围内时,T-PSA、F-PSA不能作为PCa和BPH鉴别诊断的依据,必须结合F/T才能更好地鉴别诊断PCa和BPH。
