小肝癌射频消融治疗后患者生存及肝内肿瘤复发的有关因素分析

目的探讨射频消融(radiofrequency ablation,RFA)对≤5cm肝细胞癌(hepatocellular carcinoma,HCC)的疗效。方法2001年6月~2008年4月,对94例≤5cm的HCC进行了135次冷循环射频消融治疗,治疗途径包括超声引导下经皮穿刺(n=102),开腹(n=22),人工胸水辅助超声引导(n=11)。术后随访资料采用Kaplan-Meier模型分析患者的生存情况、肿瘤复发情况及其影响因素。结果射频消融术后1、2、3年的累计生存率分别为88.8%、72.2%、68.4%。45例术后1.5~36个月出现肝内复发,患者1、2、3年的无瘤生存率分别为58.8%、41.3%、28.1%。单因素分析显示:生存时间与肝功能Child-Pugh分级和血清甲胎蛋白水平有关(χ2=6.37,P=0.012;χ2=5.76,P=0.016);肝硬化、肝内多发病灶和高血清甲胎蛋白水平可能是术后肝内复发的危险因素(χ2=3.87,P=0.049;χ2=4.50,P=0.034;χ2=4.28,P=0.039)。结论对≤5cm的HCC,RFA是一种有效治疗方法。

Factors Influencing the Survival Rates and Intrahepatic Recurrence after Radiofrequency Ablation for Small Hepatocellular Carcinoma

Objective To evaluate the therapeutic efficacy of radiofrequency ablation(RFA)in patients with small hepatocellular carcinoma(HCC,less than 5 cm in diameter).MethodsBetween June 2001 and April 2008,94 small HCC cases(76 men and 18 women;mean age,56.8 years)received 135 RFA sessions via percutaneous or celiotomy approach.The tumors close to the diaphragmatic dome were treated via an artificial pleural effusion.After the treatment,the survival probabilities were analyzed using Kaplan-Meier method.Results The ...
