2、PCR)k~'l65例HCC患者和30例健康对照组的血清miR一125b表达量,分析其对HCC的诊断价值,以及与HCC临床病理资料参数间的关系。结果:HCC患者组血清miR一125b表达与对照组相比较低,且两者的差异有统计学意义(P<0.05)。miR一125b的表达与患者性别、年龄、乙肝表面抗原阳性、AFP、ALT和仅一GGT的表达水平无关(P>0.05)。miR一125b的表达与患者肝硬化、肿瘤大小和TNM分期有关,且差异有统计学意义(尸l<0.05)。单独检测miR一125b的ROC曲线下的AUC为O.917(95%CI
3、:O.851~0.960,P<0.001),灵敏性为85.9%,特异性为93.5%,联合miR一125b和AFP检测的ROC曲线下的AUC为0.951(95%CI:O.894~0.982,P<0.001),灵敏性为92.9%,特异性为93.5%,检测AFP<20g/L的HCC患者血清miR一125b的ROC曲线下的AUC为0.889(95%CI:O.776~0.957,P<0.001),灵敏性为84.0%,特异性为87.1%。结论:联合检测血清miR一125b和AFP对早期诊断原发性HCC具有重要的临床价值。关键词原发性肝细胞
