摘要
为判断肝癌标志物对原发性肝癌诊断的意义，对１９７例良、恶性肝病、恶性胃肠道肿瘤病人及５１例正常人进行了γ－谷氨酰转肽酶同功酶ＩＩ（γ－ＧＴＰ－ＩＩ）、血清甲胎蛋白（ＡＦＰ）的检测，并对全部肝癌病人及４３例伴有ＡＦＰ升高的良性肝病病人进行了ＡＦＰ异质体分析。在１０４例原发性肝癌（ＰＨＣ）中，γ－ＧＴＰ－ＩＩ特异性最高（９５．７％），ＡＦＰ异质体的敏感性最好（８４．６％），其各自的阳性率在ＡＦＰ≥４００μｇ／Ｌ组及ＡＦＰ＜４００μｇ／Ｌ组差异均无显著性；在血清ＡＦＰ浓度不同时，两者各自的阳性率亦未见差异（Ｐ＞０．０５）；两者联合检测，共检出１０４例ＰＨＣ中的９７例（９３．３％），阳性率在ＡＦＰ≥４００μｇ／Ｌ组为９５．２％，在ＡＦＰ＜４００μｇ／Ｌ组为９１．９％。结果提示：γ－ＧＴＰ－ＩＩ和ＡＦＰ异质体联合检测能提高ＰＨＣ病人的检出率，对ＡＦＰ低浓度升高的ＰＨＣ患者同样有较好的诊断价值，可部分弥补单项检测ＡＦＰ的不足。有助于ＰＨＣ病人的及早诊断。
erum α-feto protein (AFP)and γ-glutamyl transpeptidase isoenzyme II(γ-GTP-II) were assayed in104 patients with primary hepatic carcinoma(PHC).γ-GTP-II had a higher specificity of 95.7%,whileAFP a higher sensitivity of 84.6%. There was no significant difference in the positive diagnostic rate ofthe two markers in patients with AFP≥400μg/L and with AFP<400μg/L,Nor was there any differenceif the patients were divided into four groups according to the serum AFP levels of 200μg/L,400μg/L and1000μg/L,Altogether 97 of the 104 PHC patients were detected when the two markers were assaved incombination(40 out of 42 PHC patients with AFP≥400μg/L and 57 out of 62 PHC patients with AFP<400μg/L).These results suggest that combined assay of the two serum PHC markers will increase the de-tecting rate of PHC and be of value especially in those patients with normal or low serum level of AFP
