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.
