摘要 目的探讨总前列腺特异性抗原(total prostate specific antigen,TPSA)、游离前列腺特异性抗原(freeprostate specific antigen,FPSA)及FPSA/TPSA对良性前列腺增生(benign prostate hyperpasia,BPH)、慢性前列腺炎(chronic prostate inflammatory,CPI)及前列腺癌(prostate cancer,PCa)的鉴别诊断价值。方法用磁分离酶联免疫分析法(magnetic-separated enzyme immunoassay,MEIA)检测BPH 80例、CPI 76例、PCa 30例患者的TPSA、FPSA,并计算出相应的FPSA/TPSA值。结果 TPSA<4.0μg/L时68例患者无1例PCa;当TPSA≥30μg/L时,所有患者均为PCa;TPSA为4.0~10.0μg/L时,3组患者差异无统计学意义(P>0.05),而BPH患者FPSA/TPSA与PCa患者差异有统计学意义(P<0.01),与CPI患者差异无统计学意义(P>0.05);在10μg/L<TPSA<30μg/L时,CPI与PCa患者之间的FPSA/TPSA差异有统计学意义(P<0.01)。结论运用FPSA/TPS比值结合TPSA含量可以提高PCa、CPI、BPH的鉴别诊断特异性。
