目的 :探讨经皮肝穿刺射频治疗肝癌的安全性和有效性。材料和方法 :采用RF2 0 0 0射频治疗仪在超声引导下将射频集束电极针放置于肝肿瘤内进行治疗。结果 :3 0例肝癌患者 (肿瘤最大直径≤ 5cm ,2 3个病灶 ;肿瘤直径 >5cm ,2 3个病灶 )经过治疗 ,肿瘤完全缓解和部分缓解占 5 4.3 % (2 5 / 46)。半年生存率 93 .3 % ,1年生存率为 75 %。除 2例出现肿瘤细胞针道种植转移外 ,未见其他严重并发症。结论 :射频治疗肝癌是一种相对安全、有效的方法。对于肿瘤直径≤ 5cm的肝癌治疗效果较佳 ;对于肿瘤直径 >5cm者 ,应提倡配合其他局部介入的综合治疗。
Objective: To investigate the safety and efficacy of percutaneous transhepatic radiofrequency ablation of liver cancer. MATERIALS AND METHODS: RF2 0 0 0 radiofrequency ablation instrument was used to place the RF bundling electrode needle in the liver tumor under the guidance of ultrasound. Results: The complete remission and partial remission accounted for 53.3% (25/46) in 30 patients with hepatocellular carcinoma (maximum tumor diameter ≤ 5cm, 23 lesions; tumor diameter> 5cm, 23 lesions) after treatment. Half-year survival rate of 93.3%, 1-year survival rate of 75%. No other serious complications were found in 2 cases, except for the needle-tumor metastasis of tumor cells. Conclusion: RF treatment of liver cancer is a relatively safe and effective method. For tumor diameter ≤ 5cm better treatment of liver cancer; for tumor diameter> 5cm, should be combined with other local interventions should be advocated.
