摘要 目的:分析评价血清前列腺特异抗原和前列腺特异抗原密度对前列腺癌诊断价值。方法:选择52例前列腺癌患者及50例前列腺良性增生患者为研究对象,采用化学发光免疫分析法测定血清前列腺特异抗原水平,并计算前列腺特异抗原密度,比较两组患者数据差异,并以ROC曲线评价其诊断价值。结果:患者PSA分布的组间差异有统计学意义(χ2=31.486,P<0.01);PSAD分布的组间差异有统计学意义(χ2=56.854,P<0.01)。PSA值提高敏感度相应下降,特异性提高,PSAD在各阶段的敏感度及特异性均较高。结论:前列腺癌诊断中采用血清前列腺特异抗原和前列腺特异抗原密度评价有一定的价值,其中前列腺特异抗原密度的准确度及特异性较高,对于前列腺癌和良性增生的鉴别中有重要的意义。
