To observe the curative effect of percutaneous microwave coagulation therapy (PMCT) with 2450 MHz microwave antenna for hepatocellular carcinoma.
Under local or epidural anesthesia, a thin percutaneous microwave antenna was introduced with ultrasound guidance into the tumor in the liver for thermo-coagulation.
Among the 97 hepatic cancer lesions in 52 patients, 61(62.9%) with phi < 3 cm were coagulated once. In follow-up of 6-12 months of these lesions, 57(93.4%) showed no recurrence by CT or MRI. Thirty-six (37.1%) with 3 cm < phi < 5 cm coagulated twice showed that 27 (75.0%) gave CR and 9 (25.0%) gave PR by CT or MRI in follow up of 6 months. There were no serious clinical side effects or complications in the PMCT patients.
Percutaneous microwave coagulation therapy gives good curative effect on liver tumor with phi < 3 cm. It is partly effective on lesions 3 cm < phi < 5 cm.
观察采用2450兆赫微波天线行经皮微波凝固治疗（PMCT）对肝细胞癌的疗效。
在局部或硬膜外麻醉下，在超声引导下将一根细的经皮微波天线插入肝脏肿瘤内进行热凝固。
52例患者的97个肝癌病灶中，直径<3厘米的61个（62.9%）病灶一次凝固。对这些病灶进行6至12个月的随访，通过CT或MRI检查，57个（93.4%）无复发。直径3厘米<直径<5厘米的36个（37.1%）病灶凝固两次，在6个月的随访中，通过CT或MRI检查显示27个（75.0%）达到完全缓解（CR），9个（25.0%）达到部分缓解（PR）。PMCT患者未出现严重的临床副作用或并发症。
经皮微波凝固治疗对直径<3厘米的肝肿瘤疗效良好。对直径3厘米<直径<5厘米的病灶有一定疗效。
