超声造影与增强螺旋CT评估原发性肝癌非手术治疗的对比研究

目的:探讨超声造影在原发性肝癌非手术治疗评估中的价值.方法:对56例(64个病灶)经超声引导穿刺活检病理确诊的原发性肝癌患者进行非手术治疗.治疗后分别行超声造影和增强螺旋CT检查,以判断肿瘤的灭活程度,并对其判别能力进行比较.结果:超声造影发现46个病灶没有增强(46/64),18个病灶有部分增强(18/64).增强螺旋CT发现48个病灶没有增强(48/64),16个病灶有部分增强(16/64).与临床追踪结果比较,超声造影和增强螺旋CT对非手术治疗疗效判定的敏感性、特异性及准确率分别为94.4%,97.8%,96.9%和83.3%,97.8%,93.8%,差异有统计学意义(P＞0.05).结论:超声造影是判定非手术治疗原发性肝癌效果的一种敏感而有效的方法.对肝动脉插管栓塞化疗(TACE)疗效评估及少数血供不是特别丰富的病灶,超声造影具有较增强螺旋CT更重要的临床价值.

Comparison of treatment response in primary hepatocellular carcinomas withcontrast-enhanced ultrasonography and contrast-enhanced helical CT

Objective To investigate the value of contrast-enhanced ultra sonography for non-surgical treatment response in hepatocellular carcinomas. Methods Non-surgical therapies were performed on 56 patients (64 liver neoplasms) who were diagnosed by ultrasonography-guided biopsy before the therapy. Contrast-enhanced ultrasonography(CEUS) and contrast-enhanced helical CT were performed to assess the treatment response. Results Forty-six of the 64 lesions were not enhanced with CEUS.Partial enhancement was demonstrated in the other 18 lesions. Forty-eight of the 64 lesions were not enhanced with contrast-enhanced helical CT. Partial enhancement were demonstrated in the other 16 lesions.The sensitivity, specificity, and accuracy were 94.4%,97.8%, and 96.9% for CEUS and 83.3%,97.8%, and 93.8% for contrast-enhanced helical CT (P>0.05). Conclusion CEUS is a good method in assessing the non-surgical treatment response in hepatocellular carcinomas and is more sensitive and useful than contrast-enhanced helical CT in assessing the treatment response of transcatheter hepatic arterial chemoembolization.
