摘要

目的对比分析超声造影引导下单极射频消融（M-RFA）与无接触多极射频消融（No-touch RFA）治疗肝肿瘤的临床应用价值。方法回顾性分析在我院行超声造影引导下M-RFA和No-touch RFA治疗肝肿瘤的94例患者（M-RFA组44例

No-touch RFA组50例）的检查资料

比较两组患者术后病灶灭活范围和灭活率

以及治疗前后实验室检查指标的差异;随访24个月

观察患者的无瘤生存率。结果射频消融后

超声造影测量M-RFA组肿瘤灭活范围平均值为38.36 mm×31.31 mm

No-touch RFA组为46.70 mm×35.82 mm;M-RFA组完全灭活率为90.9%（40/44）

No-touchRFA组为98.00%（49/50）

差异有统计学意义（P<0.05）。M-RFA组21例患者甲胎蛋白阳性

RFA术后1个月9例明显下降

12例转阴;No-touch RFA组20例患者甲胎蛋白阳性

RFA术后1个月6例明显下降

14例转阴

两组术前术后比较差异均有统计学意义（均P<0.001）。术后随访24个月

M-RFA组无瘤生存率为47.72%（21/44）

No-touch RFA组为68.00%（34/50）

差异有统计学意义（P=0.041）。结论超声造影引导下No-touch RFA治疗肝肿瘤有助于提高肿瘤的灭活率

疗效显著

无瘤生存率高

较M-RFA临床应用价值更佳。

Abstract

Objective To investigate the clinical value of contrast-enhanced ultrasound（CEUS）guided monopolarradiofrequency ablation（M-RFA）and no-touch multipole radiofrequency ablation（No-touch RFA）in the treatment of livertumors.Methods A total of 94 cases of liver tumors patients treated with M-RFA and No-touch RFA under the guidance ofreal-time CEUS in our hospital were enrolled

including 44 cases of M-RFA group and 50 cases of No-touch RFA group.Thepostoperative lesion inactivation range

inactivation rate and lab examination indexes before and after treatment were compared.The patients were followed up regularly for 24 months and the tumor-free survival rate was recorded.Results After treatment

the average inactivation range of the M-RFA group and the No-touch RFA group by CEUS were 38.36 mm×31.31 mm and46.70 mm×35.82 mm

respectively.The total inactivation rate of the M-RFA group and the No-touch RFA group were 90.9%（40/44）and 98.00%（49/50）

respectively.The difference was statistically significant（P<0.05）.After treatment

21 AFP positivepatients in the M-RFA group

12 cases were transferred into negative AFP and serum AFP level in 9 cases decreasedsignificantly 1 month after treatment. 20 AFP positive patients in the No-touch RFA group

14 cases were transferred intonegative AFP and serum AFP level in 6 cases decreased significantly 1 month after treatment.The difference of preoperative andpostoperative AFP levels between the two groups were statistically significant（both P<0.05）.Regular follow-up to 24 months after treatment showed that the tumor-free survival rate was 47.72%（21/44）in the M-RFA group and 68.00%（34/50）in theNo-touch RFA group

and the difference was statistically significant（P=0.041）.Conclusion CEUS guided No-touch RFAtreatment of liver tumors is helpful to improve the tumor inactivation rate with significant efficacy and high tumor-free survivalrate

which has better application value than M-RFA.
