摘要
目的探讨肝细胞癌(HCC)患者血清甲胎蛋白(AFP)异质体含量与肝癌细胞血行播散的关系。 方法应用凝集素亲和免疫电泳自显影法和巢式逆转录聚合酶链反应(RT-PCR)分别检测AFP阳性HCC患者手术前外周血AFP异质体含量和AFP mRNA,分析血清AFP异质体含量和肝癌细胞血液播散之间的相关性。结果 在46例HCC患者中,37例手术前血清AFP异质体≥20％,阳性率为80.4％;24例手术前外周血可检出AFP mRNA,检出率为52.2％。在37例AFP异质体≥20％的HCC患者中,22例外周血AFP mRNA阳性,阳性率为59.5％;而在9例AFP异质体含量<20％的HCC患者中,仅2例外周血AFP mRNA阳性,阳性率为22.2％。两组之间差异有显著性(X2=4.02,P<0.05)。 结论肝癌患者血清AFP异质体含量升高与外周血循环中存在肝癌细胞有关。
Objective To investigate the relationship between serum alpha-fetoprotein (AFP) variant levels in patients with hepatocellular carcinoma (HCC) and cancer cells disseminating through blood. Methods Serum AFP variant levels were measured by crossed immunoaffino-electrophoresis in the presence of lectin before initial surgical treatment in HCC patients. Circulating tumor cells were simultaneously detected in pre-operative blood samples using reverse transciption-polymerase chain reaction (RT-PCR) for AFP mRNA. Results Forty-six HCC patients with serum AFP positive were studied. Serum AFP variant level>20% was showed in 37 patients, among whom there were 22 (59.5%) showing AFP mRNA positive. In contrast, the positive AFP mRNA expression was only observed in 2 out of 9 patients (22.2%) with AFP variant level<20% ( x2=4.02, P<0.05). Conclusion In hepatocellular carcinoma patients, increased AFP variant levels are associated with a haematogenuous spread of tumor cells.
