高强度聚焦超声联合动脉栓塞化疗治疗晚期肝癌的初步临床研究

目的　探讨高强度聚焦超声 (HIFU)联合经动脉栓塞化疗 (TACE)治疗晚期肝癌的有效性。方法　 5 0例不能手术切除的晚期肝癌患者 (TNM分期Ⅳ期 )随机分为两组 :(1)单纯TACE组 2 6例 ;(2 )HIFU联合TACE组 2 4例 ,在TACE治疗后 2～ 3周 ,接受HIFU治疗。全部患者随访 3～ 2 4个月 ,平均 (8.16± 2 .79)个月。应用Kaplan Meier等统计学方法分别比较了两组患者的中位生存时间、6个月和 1年生存率、死亡患者平均生存时间。结果　HIFU联合TACE治疗组患者的中位生存时间为11.3个月 ,6个月和 1年生存率分别为 80 .4 %～ 85 .4 %和 4 2 .9% ;而TACE治疗组患者的中位生存时间为 4个月 ,6个月和 1年生存率分别为 13.2 %和 0 % ,两组比较 ,差异有显著性 (P <0 .0 1)。HIFU联合TACE治疗组死亡患者的平均生存时间为 (10 .2 1± 4 .12 )个月 ,而TACE组患者为 (4 .35± 2 .39)个月 ,两组比较 ,差异有显著性 (P <0 .0 1)。结论　HIFU联合TACE治疗晚期肝癌患者的疗效明显优于单纯TACE ,此联合治疗有望成为不能手术切除肝癌的一种有效手段。

High intensity focused ultrasound therapy combined with transcatheter arterial chemoembolization for advanced hepatocellular carcinoma

OBJECTIVE: To study high intensity focused ultrasound (HIFU) therapy combined with transcatheter arterial chemoembolization (TACE) in the treatment of patients with advanced hepatocellular carcinoma (HCC). METHODS: Fifty patients with unresectable HCC (TNM stage IV) were randomized into a TACE (T) group and a TACE plus HIFU (T + H) group. Twenty-six patients underwent TACE alone, and 24 HIFU ablation 2 - 3 weeks after TACE. The mean follow-up time for all patients was 8.16 +/- 2.79 months (range 3 to 24 months). The median survival, 6-month-, 1-year survival rates and average survival of patients who died were calculated by Kaplan-Meier method and Fisher exact test. RESULTS: The median survival time, 6-month and 1-year survival rates were 11.3 months, 80.4 - 85.4% and 42.9% in T + H group, in contrast to 4 months, 13.2% and 0% in T group with significant differences (P < 0.01). The average survival time of patients who died was 10.21 +/- 4.12 months in T + H group, as compared with 4.35 +/- 2.39 months in T group also with significant differences (P < 0.01). CONCLUSION: High intensity focused ultrasound therapy (HIFU) combined with transcatheter arterial chemoembolization (TACE), being better than TACE alone, may become one of the most effective treatments for patients with unresectable HCC.
