RESUMO
Objective To compare the clinical effects of surgical treatment and ultrasonic guidance percutaneous radiofrequency ablation(PRFA) therapy in the treatment of liver cancer.Methods 78 patiens with live cancer were randomly divided into the operation group and PRFA group,each group had 39 patients.The operation group was treated with traditional open surgery,the PRFA group was treated with radiofrequency ablation.The clinical effect was compared between the two groups.Results All patients were followed up after therapy,the 1,2,3-year survival rate between operation group and PRFA group had no significant differences (all P ＞ 0.05),but in the patients whose tumor were central type and samller than 3cm,the 1,2,3-year survival rate of PRFA group were significantly higher than operation group(x2 =4.819,4.815,4.919,all P ＜ 0.05).Conclusion Ultrasonic guidance percutaneous radiofrequency ablation therapy in the treatment of liver tumor is effective,and the effect is better than operation group,especially for the patients with central type tumor and the tumor samller than 3cm.
