目的探讨超声造影(CEUS)在肝癌经导管肝动脉化疗栓塞(TACE)治疗后疗效评估中的应用价值,并初步探讨残癌的增强模式。方法采用CEUS和DSA对95个肝细胞肝癌(HCC)TACE治疗后病灶进行观察,并与临床随访结果对比。结果 95个病灶中,7个病灶体积测值增大,余88个病灶大小未见明显变化。与临床随访结果对比,87个(91.6%)病灶存在不同程度残留,CEUS和DSA对残癌的诊断准确率分别为96.6%(84/87)、97.7%(85/87),差异无统计学意义(P>0.05)。CEUS残癌增强方式大致可分为以下4型:整体高增强型、整体低增强型、周边及内部多发点块状增强型、边缘小的团块增强型。结论 CEUS不仅能够准确对HCCTACE后疗效进行判断,且有助于客观评价残留肿瘤的血供方式。
Objective To investigate the value of CEUS in evaluating the curative effect of transcatheter hepatic arterial chemoembolization (TACE) in hepatocellular carcinoma (HCC), and to explore the enhancement mode of residual cancer. Methods The lesions of 95 hepatocellular carcinoma (HCC) treated with TACE were observed by CEUS and DSA, and compared with clinical follow-up results. Results Among the 95 lesions, the volume of 7 lesions increased and the size of the remaining 88 lesions showed no significant changes. Compared with the clinical follow-up results, there were 87 (91.6%) lesions with varying degrees of residual. The diagnostic accuracy rates of CEUS and DSA for residual cancer were 96.6% (84/87) and 97.7% (85/87) respectively, with no statistical difference Significance (P> 0.05). CEUS residual cancer enhancement methods can be broadly divided into the following four types: the overall high-enhanced, low overall enhancement, peripheral and internal multi-point block-enhanced, edge of the small block-enhanced. Conclusion CEUS not only can accurately judge the curative effect after HCCTACE, but also help objectively evaluate the blood supply of residual tumor.
