摘要: 目的比较肝动脉介入栓塞化疗（TACE）联合伽玛刀治疗与TACE联合三维适形放射治疗原发性肝癌（HCC）的疗效。方法将50例不能手术的Ⅱa或Ⅱb期HCC患者根据患者意愿和适应证分为TACE+伽玛刀治疗组（A组）25例与TACE+三维适形放射治疗组（B组）25例,两组一般情况无统计学差异。A组先行TACE（40%碘化油+CPDD+5-FU+EADM）治疗2～3次后,再进行体部伽玛刀放射治疗。B组先行2～3次TACE治疗后,再行加速器适形放射治疗。结果治疗后3个月评价疗效,A组RR率（CR+PR）为84%（21/25）,1、2、3年生存率分别为76%,45.9%,20.44%。B组的RR率为56%（14/25）,与A组比较差异有统计学意义（P<0.05）,B组1、2、3年生存率分别为79.6%,30.2%,12.6%,与A组比较差异无统计学意义（P>0.05）。结论与TACE联合适形放射治疗相比,TACE联合伽玛刀治疗HCC具有较高的近期有效率,而两种治疗的1、2、3年生存期差异无统计学意义。Abstract: Objective To evaluate the effect and tolerance of patients with hepatocellular carcinoma (HCC) treated by γ-ray three-dimensional conformal radiotherapy (3-DCRT) combined with interventional therapy or χ-ray Three Dimensional Conformal Radiation Therapy combined with interventional therapy.Methods From June 2005 to June 2008, 50 patients with HCC were randomly divided into γ-ray three-dimensional conformal radiotherapy (3-DCRT) combined with interventional therapy group (n=25) and χ-ray three-dimensional conformal radiotherapy (3-DCRT) combined with interventional therapy group (n=25) .All the 50 cases were firstly treated with TACE.γ-ray 3-DCRT was performed after 2-3 times of TACE in 25 cases and the remaining 25 cases were treated χ-ray 3-DCRT after 2-3 times of TACE.Results The overall response rate of HCC was 84% in TACE combined with γ-ray 3-DCRT group, significantly higher than that in χ-ray 3-DCRT group (56%) (P<0.05) .The total effective rate after three months and overall survival rates after 1, 2, 3 year in TACE combined with γ-ray 3-DCRT group (76% and 45.9%, 20.4%, respectively) , while the other group (79.6%and30.2%, 12.6%, respectively) , P>0.05.Conclusion The overall response rate of HCC in γ-ray 3-DCRT + TACE is better than χ-ray 3-DCRT + TACE for HCC, but the overall survival rates is not significant.
