There are few blood tests for an efficient detection of hepatocellular carcinoma(HCC) associated with hepatitis C virus(HCV) infection. The abilities of quantitative analyses of 7 genes hypermethylation in serum DNA, -fetoprotein(AFP) and prothrombin-induced vitamin K absence II(PIVKA-II), and various combinations to detect HCC were evaluated. An optimal hybrid detector, built using data for 2 methylated genes(SPINT2 and SRD5A2), AFP, and PIVKA-II, achieved the most satisfactory ability to detect HCC in the training cohort(n=164) and an independent validation cohort(n=258). In the validation cohort, accuracy, sensitivity, and specificity of the hybrid detector for detection of HCC were 81. 4%, 73. 2%, and 87. 7%, respectively. Notably, even when detecting HCC 2cm in diameter, the hybrid detector maintained markedly high abilities(84. 6% accuracy, 72. 2% sensitivity, 87. 7% specificity). These results show that the optimal hybrid blood detector can detect HCV-related HCC more accurately.

有几个血液检测与丙型肝炎病毒（HCV）感染相关的肝细胞癌（HCC）的有效检测。评价了血清DNA、甲胎蛋白（AFP）、凝血酶原诱导的维生素K缺乏II（PIVKA-II）7个基因甲基化定量分析及其各种组合检测HCC的能力。使用2个甲基化基因（SPINT 2和SRD 5A 2）、AFP和PIVKA-II的数据构建的最佳混合检测器在训练队列（n=164）和独立验证队列（n=258）中实现了最令人满意的HCC检测能力。在验证队列中，混合检测器检测HCC的准确性、灵敏度和特异性为81。4%，73. 2%，87。7%，分别。值得注意的是，即使在检测直径为2cm的HCC时，混合检测器也保持了显着的高能力（84。6%的准确率72. 2%的灵敏度87. 7%特异性）。这些结果表明，优化的混合血液检测器可以更准确地检测HCV相关的HCC。
