ABSTRACT
Objective To investigate the effect of transcatheter arterial chemoembolization combined with radiofrequency ablation in the treatment of primary hepatocellular carcinoma (HCC) and its influence on the levels of nuclear factor kappa B (NF-B) and p53.Methods 90 patients with primary HCC were selected,and they were randomly divided into control group (n =45) and observation group (n =45) according to the digital table.The control group received chemoembolization treatment,the observation group was given combined radiofrequency ablation treatment.The patients were continuously treated for 6 months.Immunohistochemical assay was used to detect the expression of NF-B and p53 in two groups.The clinical curative effect and influence on the expression of NF-B and p53 were compared between the two groups.Results After 6 months of treatment,the Karnofsky score of the observation group was (84.32 ± 12.31)points,which was higher than (64.32 ± 11.24) points of the control group (t =21.295,P ＜ 0.05).After treatment for 6 months,the AFP level of the observation group was (121.23 ± 1.43) μg/L,which was lower than (189.44 ± 36.42) μg/L of the control group (t =19.853,P ＜ 0.05).After treatment,the positive expression rates of NF-B and p53 of the observation group were 24.44％ and 20.00％,respectively,which were lower than 40％ and 33.33 ％ of the control group (x2 =6.597,5.784,all P ＜ 0.05).The recurrence rate of the observation group was 15.56％,which was lower than 28.89％ of the control group (x2 =6.126,P ＜ 0.05).The 6-month and 12-month survival rates of the observation group were 86.67％ and 82.22％,respectively,which were higher than 75.56％ and 64.44％ of the control group (x2 =4.927,7.192％,all P＜0.05).Conclusion The effect of radiofrequency ablation combined with radiofrequency ablation for patients with primary liver cancer is satisfactory,which is worthy of popularization and application.
