小肝癌的射频消融治疗

目的： 总结射频消融(RFA)治疗肿瘤直径≤5cm小肝癌的疗效和经验。方法： 从1999年9月-2005年5月期间，采用RFA治疗肿瘤直径≤5cm的原发性或转移性肝癌共130例, 其中原发性肝癌86例，转移性肝癌44例。18例结合肝动脉栓塞化疗，20例同时行RFA联合瘤内无水酒精注射术。结果：1，3年总累积存活率分别为91.3%，77.7%。治疗中7例发生并发症，分别为少量胆瘘、肠瘘、轻度皮肤灼伤，未发现与治疗相关的死亡。结论：RFA对肿瘤直径≤5cm的小肝癌是一种相对安全、有效的治疗方法，并有可能达到与手术切除相似的效果。

Radiofrequency ablation in the treatment of small liver cancer

Abstract:Objective：To investigate the effect of radiofrequency ablation (RFA) in the treatment of small liver cancer. Methods：In recent 6 years, 130 patients with primary or secondary liver cancer (≤5cm in diameter)were treated by RFA, among which 86 cases were primary, and 44 cases were secondary liver cancer. Among the 130 cases, 18 received RFA plus TAEC, and 20 had RFA combined with PEI. Results：Overall 1- and 3-year survival rate was 91.3% and 77.7% respectively. Complications occurred in 7 cases, including biliary fistula, intestinal fistula, and slight burn of skin. There was no death in this series. Conclusions：RFA is an effective and safe therapeutic approach for small liver cancer ≤5cm in diameter. Its effect may be similar to that of surgical resection.
