目的 探讨经皮肝穿刺射频治疗肝癌的有效性、安全性和肿瘤局部的控制情况。 方法 采用RF2 0 0 0射频治疗仪在超声引导下将射频电极放置于肝肿瘤内进行治疗。 结果 (1) 30例肝癌患者 (肿瘤病灶直径 <5 cm及 >5 cm各 2 3个 )经过治疗 ,肿瘤完全缓解和部分缓解率占 5 4 .3% (2 5 /46 )。半年生存率为 93.3% ,1年生存率为 75 %。 (2 ) 2例出现肿瘤细胞针道种植转移 ,其他未见严重并发症。 结论 射频治疗肝癌是一种安全、有效的方法。对于肿瘤直径 <5 cm的肝癌治疗效果较佳 ;对于肿瘤直径 >5 cm者 ,应配合其他局部介入的综合治疗
Objective To investigate the effectiveness and safety of percutaneous transhepatic radiofrequency ablation of liver cancer and local control of tumor. Methods The radiofrequency electrode was placed in the liver tumor under the guidance of ultrasound with RF2 0 0 0 radiosensitizer. Results (1) The complete remission and partial remission rates of 30 HCC patients (23 tumor diameters <5 cm and> 5 cm) were treated by treatment, accounting for 54.3% (25/46) of the complete remission. Half-year survival rate was 93.3%, 1-year survival rate was 75%. (2) There were 2 cases of tumor cells transplanted into the needle pathways without any serious complications. Conclusion Radio frequency treatment of liver cancer is a safe and effective method. For the tumor diameter <5 cm of the treatment of liver cancer is better; for tumor diameter> 5 cm, should be combined with other local interventional comprehensive treatment
