2、敏感度、特异度及准确度进行比较。结果GP73曲线下面积(AUROC)0.759(95%C/:0.683~0.836),敏感度为72.1%,特异度为63.1%,最佳临界点为98.60ng/L。AFP的AUROC为O.857(95%C/:0.792~0.992),敏感度为59.0%,特异度为76.O%,最佳临界点为20:40L。GP73联合AFP检测,灵敏度为86.9%,特异度为98.3%,AUROC为0.926(95%C/:0.875~0.976)。结论GP73准确度低于AFP,灵敏度高于AFP,因此应用于
3、HCC筛查有其独特优势;GP73和AFP联合检测可提高HCC筛查效果。【关键词】癌,肝细胞;高尔基体蛋白.73;肿瘤标记,生物学;特异度;敏感度GlP73versusAFPinscreeningoftheprimaryhepatocellularcarcinomaLuoYanxiang,GongXueyLMingfang,WuBiaohua,SuNianhua,HuangYuling,WangPanpan.CancerResearchInstitution,ZhongshanAfiliatedHospit
