AFP作为原发性且肝癌(PHC)的诊断指标,在临床早已产生共识,然而约有近40％的PHC属AFP阴性或低浓度者,这部分患者有的甚至在癌症晚期AFP尚在正常范围。自80年代初Deugnier等先后报道PHC病人血AFU活性明显高于正常人以来,对AFU的研究受到广泛重视。为探讨AFU对PHC,尤其是AFP阴性PHC的诊断价值,本文检测了 AFP as a diagnostic indicator of primary and hepatocellular carcinoma (PHC) has long been consensus in the clinical, but about 40% of PHC is AFP-negative or low concentrations, and some of these patients even in the late stage of cancer AFP is still in the normal range . Since Deugnier et al. reported successively that the blood AFU activity of PHC patients was significantly higher than that of normal people since the early 1980s, the research on AFU has received extensive attention. In order to investigate the diagnostic value of AFU on PHC, especially AFP-negative PHC, this article examined
