为了探讨彩超引导下经皮水冷循环微波热凝固治疗肝脏恶性肿瘤手术(PMCT)的临床疗效,对53例原发性及转移性中小肝癌患者(共87个病灶)彩超引导下行PMCT,根据肿瘤大小和患者的耐受情况选择不同微波功率和作用时间,治疗后15 d用彩超造影复查评估短期疗效,并观察1年和2年生存率。微波治疗后彩超造影显示,61个治疗区内部各期均无异常增强区,提示肿瘤完全灭活,一次消融率为70.1%(61/87),其他26个治疗区〔29.9%(26/87)〕边缘局部或内部有早期结节状增强,判断有肿瘤残存。随访2年,3例失访,1年和2年生存率分别为79.2%(42/53)和49.1%(26/53)。PMCT术治疗原发性或转移性中小肝癌疗效好,创伤小,快速、简便,可重复,是一种有效的治疗方法。
To investigate the clinical efficacy of color Doppler ultrasonography in the treatment of hepatic malignant neoplasms (PMCT) under microwave-assisted thermal coagulation, PMCT was performed in 53 patients with primary and metastatic HCC (87 lesions) And patient tolerance to choose different microwave power and duration of action, 15 d after treatment with color Doppler ultrasound review of short-term efficacy and to observe 1-year and 2-year survival rate. The color Doppler echocardiography after microwave treatment showed that there were no abnormal enhancement zones in all the 61 treatment zones, suggesting complete tumor inactivation. The primary ablation rate was 70.1% (61/87) and the other 26 treatment zones (29.9%, 26/87 )〕 Edge of the local or internal early nodular enhancement, to determine the residual tumor. After 2 years of follow-up, 3 patients were lost to follow-up. The 1-year and 2-year survival rates were 79.2% (42/53) and 49.1% (26/53), respectively. PMCT surgery for the treatment of primary or metastatic small and medium liver cancer, trauma, rapid, simple, repeatable, is an effective treatment.
