摘 要:目的回顾性比较转换器介导下多电极射频消融(RFA)与传统RFA治疗早期肝细胞癌(HCC)的局部疗效和安全性。方法对82例早期肝细胞癌患者的82个结节分别采用转换器介导下的多电极RFA(转换器组,n=43)或传统RFA(n=39)进行治疗,比较两组的消融参数、局部完全消融率、主要并发症及肿瘤局部进展发生率。结果转换器组的消融时间[(16.7±3.4)min]显著短于传统RFA组[(29.8±10.4)min](P〈0.05),而两组之间穿刺针数及消融灶大小的差异均无统计学意义(P〉0.05)。首次治疗后转换器组的局部完全消融率为100%(43/43),传统RFA组为94.9%(37/39)(P〉0.05)。术后随访(26.4±21.8)个月,转换器组和传统RFA组的肿瘤局部进展发生率分别为16.3%(7/43)和17.9%(7/39),其中1年的发生率分别为16.1%和11.2%,2年的发生率分别为20.5%和20.6%(P=0.666)。结论转换器介导下的多电极RFA可以在较短的时间内安全、有效地治疗单发的早期HCC。Objective To retrospectively compare the safety and local efficacy of multiple-electrode switching based radiofrequency ablation (RFA) and the conventional RFA in treating single early-stage hep- atocellular carcinoma (HCC). Methods A total of 82 patients with single early-stage HCC received either RFA with a multiple-electrode switching system (n = 43 ) or conventional RFA (n = 39) as the first-line treatment. The rate of initial local complete response, major complications and local tumor progression (LTP) were compared between two groups. Results The total ablation time was significantly shorter in the switching-RFA group [ ( 16. 7±3.4 ) mins] than in the conventional RFA group [ ( 29. 8±10. 4 ) mins ] (P 〈0. 05 ). The rate of initial local complete response was 100% (43/43) in the switching-RFA group and 94. 9% (37/39) in the conventional RFA group (P 〉0. 05). After a mean follow-up period of (26.4±21.8) months (ranging 3.0- 91.6 months), the rates of LTP in the switching-RFA group and conven- tional RFA group were 16. 3% (7/43) and 17.9% (7/39), respectively. The LTP rates in two groups were 16. 1% versus 11.2% at year 1, and 20.5% versus 20.6% at year 2 (P=0.666). Conclusions The multiple-electrode switching based RFA is safe and effective with shorter ablation time in treating single early-stage hepatocellular carcinoma.
