摘要:

目的 探讨TP53基因单核苷酸多态性(SNP)与原发性肝细胞癌患者预后的关系。方法 采用聚合酶链反应-限制性片段长度多态性技术(PCR-RFLP)检测213例肝细胞癌术后患者TP53基因rs1625895、rs9895829、rs28934578位点的基因型。采用Log-rank检验法绘制肝癌术后患者的Kaplan-Meier生存曲线;采用多因素Cox比例风险回归分析探究肝癌患者术后预后的影响因素。结果 在共显性模型(HR=2.190,95%CI:1.142~4.201,P=0.018)和隐性模型(HR=2.275,95%CI:1.225~4.227,P=0.009)中,携带rs1625895 AA基因型的患者预后更差;Cox比例风险回归分析显示, rs1625895多态性(HR=2.169,95%CI:1.015~4.637,P=0.046)是肝细胞癌患者术后预后的危险因素。结论 TP53基因rs1625895多态性与肝细胞癌患者术后预后相关。

Abstract:

Objective To explore the relationship between single nucleotide polymorphism (SNP) of TP53 gene and postoperative prognosis in patients with primary hepatocellular carcinoma (HCC). Methods Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to detect the genotypes of rs1625895, rs9895829 and rs28934578 of TP53 gene in 213 HCC patients after operation. The Log-rank test was used to plot the Kaplan-Meier survival curves of postoperative HCC patients. Multifactorial Cox proportional risk regression analysis was used to explore influencing factors of postoperative prognosis of HCC patients. Results Patients carrying the rs1625895 AA genotype had a worse prognosis in both co-dominant (HR=2.190, 95%CI: 1.142-4.201, P=0.018) and implicit models (HR=2.275, 95%CI: 1.225-4.227, P=0.009). Cox proportional risk model analysis showed that the rs1625895 polymorphism (HR=2.169, 95%CI: 1.015-4.637, P=0.046) was a risk factor for the prognosis of patients with HCC after surgery. Conclusion TP53 gene rs1625895 polymorphism is associated with postoperative prognosis in hepatocellular carcinoma patients.
