Comparison the treatment effects of radiofrequency ablation and surgical resection for small primary liver carcinoma

To compare results of surgical resection(SR)and radiofrequencyablation(RFA)for small primaryliver carcinoma.The followp results of 116 small primary liver carcinoma cases treated with surgical resection and small primary liver carcinoma cases treated with radio frequency ablation were analyzed. Results:The mean followp time was upto 34.36(1-72)months. The 1,3 Sear disease free survival rates in SR and RFA group were 85.4%, 40.9%, 29.2% and 82.6%,27.7%,16.4% and the mean disease free survival time were 32.78-29. 39 months(P=0.51),and the mean cumulative survivaltime were 46.91 and 46. 68 months(P=0. 67)respectively. The 1,3,Sear disease free survival rates in SR and RFA group withtumor diameter were 85.7 % 62.5 %,37.5 % and 85.0 %,37.4%, 29.9% (P=0. 50)and the mean cumulative survival timewere 97.1%, 70.9%, 64.2% and 100.0%, 69.3%,59.9% (P=0. 87)respectively but for the cases with tumor diameter in 3-5.
