摘  要:目的评价伽玛刀治疗未能行手术的早期肝细胞肝癌(HCC)的疗效。方法对28例不宜行手术治疗或不愿行手术治疗的直径≤5cm的HCC患者行伽玛刀治疗,以50%等剂量曲线覆盖计划靶区(planning target volume,即V)100%,70%等剂量曲线覆盖PTV〉85%为计划要求,处方剂量3.8~6.1Gy/次,6~8次,3次/周,2—3周内完成。用Kaplan Meier分析生存率。结果完全缓解(CR)12例(42.8%),部分缓解(PR)10例(35.7%),无变化(NC)5例(17.9%),进展(PD)1例(3.6%)。总有效率(CR+PR)22例(78.6%)。6月、1、2和3年生存率分别为100.0%、92.9%、82.1%和77.3%。结论伽玛刀对早期肝细胞肝癌患者的治疗是安全有效的,不良反应较小。当患者不宜行手术或拒绝手术时,低分次、高剂量伽玛刀治疗是早期HCC局部治疗的好选择。Objective To evaluate the therapeutic effect of γ-knife radiotherapy for unresectable early hepatocellular carcinoma (HCC). Methods Twenty-eight patients with unresectable HCC (size ≤5 cm ) underwent γ-knife radiotherapy. During the procedure the 50% isodose line covered 100% of planning target volume and the 70% isodose line covered more than 85% of planned target volume. The protocol was 3.8 -6.1 Gy × 3/week for 2 -3 week. The cumulative survival rates were analyzed hy Kaplan Meier method. Results In this group of patients, complete response (CR) was reached in 12 case(42.8% ) ,partial response (PR) in 10(35.7% ) , no change (NC) in 5 ( 17.9% ) and one patient (3.6%) showed progressive disease (PD) , with an effective rate (CR + PR) of 78.6% (22/28). The overall survival rates at 0.5,1,2 and 3 years were 100.0% ,92.9% ,82.1% and 77.3% ,respectively. Conclusion The γ-knife is an effective approach for early hepatocellular carcinoma with low toxicity and it may be recommended as a local treatment for inoperable HCC patients or for those who refuse to be operated.
