经动脉化疗栓塞治疗肝细胞癌疗效评估中C臂CT技术应用

The application of C-arm CT imaging technique in evaluating the efficacy of TACE for hepatocellular carcinoma

目的探讨C臂CT技术在经动脉化疗栓塞(TACE)治疗肝细胞癌疗效评估中的应用价值。方法 2012年9月—2013年3月对80例肝细胞癌患者行TACE治疗时采用C臂CT扫描。通过评阅C臂CT平扫、动脉早期、动脉实质期图像及后处理图像,观察TACE治疗后肿瘤病灶存活、碘油沉积、供血动脉栓塞等情况,评估TACE疗效。结果 80例患者C臂CT扫描检出病灶139个。TACE治疗后,75例患者的128个病灶(128/139,92.09%)C臂CT扫描即时评价疗效结果满意,其中存活肿瘤较少78个、中等29个、较多21个;碘油沉积致密64个、中等39个、稀疏25个;栓塞治疗后肿瘤血供明显减少101个,无明显减少27个。结论肝细胞癌患者TACE治疗后行C臂CT扫描,可以便捷、准确、全面的观察病灶存活肿瘤、碘油沉积、供血动脉栓塞是否完全等情况,可作为TACE疗效评估的重要手段。

Objective To investigate the application of C- arm CT imaging technique in evaluating the efficacy of transarterial chemoembolization（TACE） for hepatocellular carcinoma（HCC）. Methods During the period from Sep. 2012 to Mar. 2013 at authors’ hospital, C- arm CT scanning was employed during the performance of TACE in 80 patients with HCC. The residual active tumor lesions, Lipiodol deposition and the embolization of the feeding arteries after TACE therapy were assessed by C- arm CT plain scan images and the images of early artery phase and parenchymal phase, as well as the post- processing images. The efficacy of TACE was thus evaluated. Results A total of 139 hepatic tumors were detected in 80 patients by C- arm CT imaging. C- arm CT scanning performed immediately after TACE showed that satisfactory result was obtained in 128 lesions of 75 patients（128/139, 92.9%）. Fewer, medium and more residual active tumors were seen in 78, 29 and 21 lesions respectively, while dense, moderate and thin Lipiodol deposition was seen in 64, 39 and 25 lesions respectively. After TACE therapy obvious decrease in blood supply was demonstrated in 101 lesions, while no obvious decrease in blood supply was seen in 27 lesions. Conclusion C- arm CT scanning after TACE for patients with HCC can conveniently, accurately and comprehensively reveal the residual active tumors, Lipiodol deposition and embolization status of feeding arteries. Therefore, this technique should be regarded as an important means to evaluate the efficacy of TACE.
