经皮射频消融术与微波消融治疗肝癌的治疗效果对比

Comparison of Efficacy of Percutaneous Radiofrequency Ablation and Microwave Ablation for Liver Cancer

目的比较经皮射频消融术(RFA)与微波消融术(MWA)治疗肝癌的可行性和安全性。方法 110例肝癌患者,分为两组,50例患者接受经皮射频消融术,60例接受微波消融术。比较射频组和微波组的生存率、肿瘤消融率、局部复发率、并发症发生率。结果射频组和微波组的1、3、5年累积生存率分别为96.2%、74.1%、63.4%,94.2%、70.5%、61.7%;肿瘤消融率射频组为98.3%,微波组为97.7%;局部复发率分别为12.0%和15.0%;并发症发生率分别为6.0%和8.3%。结论经皮射频消融术与微波消融术治疗肝癌的治疗效果无明显差异,在临床治疗中具有安全性和有效性。

Objective To compare the feasibility and safety of percutaneous radiofrequency ablation( PRFA) and microwave ablation( MWA) for liver cancer. Methods 110 cases of patients with liver cancer were divided into 2 groups,50 patients received PRFA,60 patients received MWA. The survival rate,tumor ablation rate,local recurrence rate,and complications between the 2 groups were compared. Results In PRFA group and MWA group,1-,3-and 5-year cumulative survival rates were96. 2%,74. 1%,63. 4%,and 94. 2%,70. 5%,61. 7%; tumor ablation rates were 98. 3% and 97. 7%; local recurrence rates were 12% and 15%; the rate of complications were 6. 0% and 8. 3% respectively. Conclusion PRFA and MWA for hepatocellular carcinoma have similar therapeutic effects,and safety and effectiveness in the clinical treatment.
