摘　　要：目的:用频率为2450MHZ微波治疗机,14G深部组织间插入型电极,超声引导下经皮穿刺,微波热凝固治疗肝癌30例,观察疗效。方法:肿瘤直径3cm以下单结节型15例,3cm以上多发15例,微波功率60W每次60s,使电极尖端部2.5X1.5cm范围内可凝固坏死。3cm以下2～5次。3cm以上反复多次,直至完全凝固坏死。经增强CT评价坏死范围。根据坏死率(TN),缩小率(TR)判定疗效。结果:坏死率显效46.6%(14例),有效93%(28例)。缩小率有效21例(70%),肿瘤局部得以良好控制。结论:如配合肝动脉拴塞(TAE),肝动脉注药(TAI)治疗,可减少残存,控制复发,进一步提高疗效。Objective：To observe the efficacy after puncturing into skin,which guided by ultrasound,by 2450 MHZ Microwave Treatment Machine,14 G deep tissue electrode inserted to cure 30cases of liver cancer. Methods：15 cases were for single nodular under 3 cm in diameter,15 cases for up 3 cm in diameter. It made the cancer concreting and dead within 2.5x1.5 cm under electrode tip. The patients with tumor under 3 cm in diameter were cured for 2 to 5times. Up 3 cm are cured repeatedly till the cancer was concreting and dead. Evaluating the dead ranges by enhanced CT. Determining the efficacy according to TN TR.Results：TN was 46.6%（14 cases）,efficient rate was 93%（28 cases）,TR was 70%（21 cases）. Part of cancer was controlled well. Conclusion：It controls relapse,reduces cancer remnant and improves effectiveness if we do TAE and TAI at the same time.
