TOCE联合HIFU治疗原发性肝癌疗效的CT评价

目的用CT评价TOCE联合HIFU治疗原发性肝癌的疗效。方法46例接受TOCE联合HIFU治疗的原发性肝癌为研究组，比较治疗前后的CT表现；随机选出同期46例单纯TOCE治疗的患者为对照组，进行对比分析。结果研究组37例(37/46，80.4％)病灶体积缩小，缩小率为(27.25±19.89)％；对照组28例(28/46，61.8％)病灶体积缩小，缩小率为(11.89±15.96)％。研究组栓塞灶周边复发5例，对照组15例。研究组肝内转移灶15例，对照组16例。在已栓塞灶瘤体大小变化及局部复发方面，前者优于后者，在肝内转移方面无明显差异。结论TOCE联合HIFU是治疗原发性肝癌的一种有效方法，CT在其疗效及预后判断中具有重要价值。

The Curative Effect of HCC after TOCE Combining with HIFU Therapy as Evaluated by CT

Objective To investigate the curative effect of hepatocellular carcinoma(HCC) after transcatheter oily chemoembolization(TOCE)combining with high intensity focused ultrasound(HIFU)therapy using CT. Methods Forty six cases with HCC underwent TOCE combining with HIFU therapy, the CT appearances were observed before and after combining therapy. Another 46 cases received simple TOCE therapy were random chosen as a control group. Results The lesions became smaller in 37 cases (37/46,80.4%) after combining treatment in the studied group,while 28(28/46,61.8%) in the control group. Local recurrence of the tumor in the studied group was found in 5 cases, while 15 cases in the control group. Liver metastases in the studied group was found in 15 cases, while 16 cases in the other group. Compared with simple TOCE, TOCE combining with HIFU therapy showed better results in respects of tumor shrinkage and local recurrence. No significant difference in liver metastases was found between these two groups. Conclusion TOCE combining with HIFU therapy is an effective and practical treatment for some HCC. CT is helpful for evaluating curative effect and prognosis. [
