摘要 目的:初步探讨乙肝病毒基因变异、基因型及亚型与肝细胞癌(HCC)发病的相关性。方法:特异探针杂交法检测乙肝病毒C启动子变异,分别用特异探针杂交和特异引物PCR两种方法鉴定病毒基因型,限制性酶切片段长度多态性法鉴定部分HCC乙肝病毒的基因亚型。结果:HCC组与非HCC(NHCC)组HBV-DNA载量无明显差异,两组HBV中A1762T/G1764A变异株分别占77.8%和44.4%。B和C型为HBV主要基因型,基因型B和C在HCC患者中分别为3例(11.1%)和24例(88.9%),在NHCC患者中分别为29例(42.6%)和35例(51.5%),HCC组24例基因型C的HBV中21例为C2亚型。结论:乙肝病毒C启动子A1762T/G1764A双变异、基因型C与HCC的发生密切相关,HCC患者HBV基因亚型主要为C2亚型。
