Abstract
目的通过检测AFP mRNA在肝细胞性肝癌(hepatocellular carcinoma, HCC)病人外周血和骨髓中的表达,探讨AFP mRNA作为HCC微转移指标的可能性.方法建立敏感的巢式逆转录聚合酶链反应体系(Nested-RT-PCR),检测71例HCC、36例肝硬化、9例肝血管瘤、11例肝转移瘤、30例正常对照外周血AFP mRNA和19例HCC、15例血液病骨髓AFP mRNA.结果 71例HCC外周血中38例AFP mRNA表达阳性(53.5%),肝硬化、肝血管瘤、肝转移瘤和正常对照均为阴性.HCC外周血AFP mRNA检出率与血清AFP值无明显相关(P>0.05),而与肿瘤大小、门静脉癌栓、肝内转移、肝外转移等临床参数有明显相关(P 0.05),与肿瘤大小、门静脉癌栓、肝外转移明显相关(P<0.05).外周血和骨髓AFP mRNA的表达呈一致性(P<0.05).结论血循环AFP mRNA可作为HCC微转移的早期检测指标.HCC病人外周血和骨髓AFP mRNA的表达与复发转移显著相关,且HCC病人外周血和骨髓AFP mRNA的表达呈一致性,联合检测有助于提高结论的可靠性.
