目的:探讨广西扶绥县肝癌高发区 HBV 相关肝癌患者 HBV-DNA 前 S 区( Pre-S 区)变异与肝癌发生的关系。方法采用病例对照研究的方法,选择 HBV 相关肝癌患者50例(肝癌组),HBV 慢性携带者50例(对照组),提取受试者血清 HBV-DNA,采用巢式 PCR 的方法扩增 Pre-S 区,测序并分析其核酸变异的情况。结果肝癌组患者 Pre-S 区缺失率、Pre-S2起始密码子变异率、T53C 变异率分别为38.0%(19/50)、38.0%(19/50)和32.0%(16/50),均高于对照组的14.0%(7/50)、10.0%(5/50),4.0%(2/50)(P <0.05)。两组发生 Pre-S 区缺失26例,主要为Ⅱ类缺失,占69.2%;框内缺失24例占92.3%;Pre-S25′端缺失23例占88.5%。多因素非条件 logistic 分析结果显示,Pre-S 区缺失、Pre-S2起始密码子变异以及 T53C 变异是肝癌发生的独立危险因素(P <0.05)。结论HBV-DNA Pre-S 区缺失、Pre-S2起始密码子变异和 T53C 变异与广西扶绥县 HBV 相关肝癌的发生密切相关。
目的:探討廣西扶綏縣肝癌高髮區 HBV 相關肝癌患者 HBV-DNA 前 S 區( Pre-S 區)變異與肝癌髮生的關繫。方法採用病例對照研究的方法,選擇 HBV 相關肝癌患者50例(肝癌組),HBV 慢性攜帶者50例(對照組),提取受試者血清 HBV-DNA,採用巢式 PCR 的方法擴增 Pre-S 區,測序併分析其覈痠變異的情況。結果肝癌組患者 Pre-S 區缺失率、Pre-S2起始密碼子變異率、T53C 變異率分彆為38.0%(19/50)、38.0%(19/50)和32.0%(16/50),均高于對照組的14.0%(7/50)、10.0%(5/50),4.0%(2/50)(P <0.05)。兩組髮生 Pre-S 區缺失26例,主要為Ⅱ類缺失,佔69.2%;框內缺失24例佔92.3%;Pre-S25′耑缺失23例佔88.5%。多因素非條件 logistic 分析結果顯示,Pre-S 區缺失、Pre-S2起始密碼子變異以及 T53C 變異是肝癌髮生的獨立危險因素(P <0.05)。結論HBV-DNA Pre-S 區缺失、Pre-S2起始密碼子變異和 T53C 變異與廣西扶綏縣 HBV 相關肝癌的髮生密切相關。

Objective To investigate the relationship between HBV-DNA Pre-S mutation and the occurrence of hepatocellular carcinoma (HCC) among patients with HBV-related HCC in high-risk region of HCC in Fusui County,Guangxi.Methods A case-control study was performed in 50 patients with HBV-related HCC(HCC group) and 50 chronic HBV carriers(control group).The serum HBV-DNA was extracted from the subjects.Nested PCR was applied to Pre-S amplification.DNA sequencing was performed to analyze the nucleic acid mutation.Results The rates of Pre-S deletion,Pre-S2 start codon mutation and T53C mutation in HCC patients were 38.0%(19 /50), 38.0%(19/50) and 32.0%(16/50),respectively,which were significantly higher than the controls(14.0%(7/50),10.0%(5/50) and 4.0%(2/50),respectively,P <0.05).There were 26 Pre-S deletion cases(69.2%),mainly of TypeⅡdeletion,24 in-frame deletion cases (92.3%) and 23 Pre-S2 5′end deletion cases(88.5%) in two groups.Multivariate unconditional logistic regression analysis revealed that Pre-S deletion,Pre-S2 start codon mutation and T53C mutation were the independent risk factors for the occurrence of HCC(P <0.05). Conclusion HBV-DNA Pre-S deletion,Pre-S2 start codon mutation and T53C mutation closely correlate with the occurrence of HCC in Fusui County,Guangxi.
