摘    要:目的探讨超声引导下微波凝固治疗复发性、转移性肝肿瘤的临床价值。方法80例肝肿瘤患者,共152个肿瘤结节在超声引导下行经皮微波凝固治疗,其中55例复发性肝癌,25例转移性肝癌,根据肿瘤大小,选择不同微波功率和作用时间。结果治疗一月后观察,彩超检查93.3%(70/75)结节血流信号消失,94.7%(144/152)结节CT增强扫描无明显强化,原血清AFP升高者73.1%(38/52)恢复正常,26.9%(14/52)下降,CEA升高者66.6%(8/12)恢复正常。随访3年中95%(76/80)无原位复发。1、2、3年存活率分别为86%、73%、53%。所有接受PMCT的患者均未出现严重并发症和副作用。结论超声引导下微波凝固治疗肝肿瘤方法简便,安全,疗效确切、副作用少,适用于复发性、转移性肝癌患者治疗。

Abstract:Objective To discuss the clinical value of ultrasound-guided percutaneous microwave coagulation therapy for metastatic or recurrent hepatocarcinomas. Methods Eighty patients with 152 tumor nodules including 55 cases of recurrent hepatic tumors and 25 cases of metastatic hepatic tumors were treated with ultrasound-guided percutaneous microwave coagulation therapy. The defferent frequency and time were selected according to tumor size. Results Collor Dopple flow imaging showed intratumoral blood flow signals disappeared in 93.3%(7075)nodules after a month for therapy, 94.7%(144152)nodules showed no enhancement on contrast-enhancement CT, AFP in 73.1%(3852) patients returned negative and in 26.9%(1452) cases decreased, CEA in 66.6%(812) patients returned negative. During a follow-up of three years, no local recurrence occurred in 76 cases(95%). The survival rate of 1,2 and 3 years were 86%,73% and 53% respectively. There were no serious complications or side effect in all patients. Conclusion The percutaneous microwave coagulation therapy for liver cancers is safe and effective. It is suitable to treat metastatic or recurrent hepatocarcinomas.
Keywords:Ultrasonography  Percutaneous microwave coagulation therapy  Metastatic hepatocarcinoma  Recurrent hepatocarcinoma
