Comparative analysis of curative effect of percutaneous radiofrequency ablation and open resection for primary small and medium liver cancer / 中国现代普通外科进展

ABSTRACT

Objective:To investigate the effects of radiofrequency ablation and hepato-recetion in the treatment of less than 5 cm of primary liver cancer.Methods:A retrospective analysis from January 2009 to December 2014 in Department of hepatobiliary surgery,Chifeng Hospital treated 255 cases of primary liver cancer patients,including 130 cases of tumors less than 5 cm.They were divided into treatment group (percutaneous radiofrequency ablation) and control group (open surgery group),To get evaluation of effects preliminarily,aH patients were followed up with ultrasonography and blood tests,etc.Results:Percutaneous radiofrequency ablation group after 1,3,5 year overall survival rate was 93.7％,69.8％,15.9％,Patients in the control group were 1,3 and 5 years overall survival rate was 92.5％,74.6％,17.9％.Two groups had no significant difference between the survival period,percutaneous radiofrequency ablation group after 1 and 3 and 5 years disease-free survival was 81％,33.3％,1.6％;laparotomy in the control group after 1,3 and 5 years disease-free survival was 88.1％,53.7％,10.4％,the difference was statistically significant between the two groups.Conclusion:Compared with the operation group,the radiofrequency ablation group recovered faster and had less complications,and the difference between the two groups was statistically significant.Compared with open operation group,primary percutaneous radiofrequency ablation for primary small and medium liver cancer has similar long-term therapeutic effect.Percutaneous radiofrequency ablation has less trauma,less complications and shorter hospital stay than that of the control group.
