三维适形放射治疗43例肝海绵状血管瘤的临床分析

Three-dimensional conformal radiotherapy for hepatic cavernous hemangiomas

目的探讨肝海绵状血管瘤精确放射治疗的疗效。方法回顾分析43例肝海绵状血管瘤患者使用三维适形放射治疗(3DCRT),三维适形治疗计划系统:设5～6个共面或非共面固定照射影靶区剂量3000 cGy,单次剂量300～500 cGy,6～10次,两周内完成治疗。结果 43例肝海绵状血管瘤患者,无1例发生放射性肝损伤或死亡,CR+PR为100%。结论三维适形放疗是治疗肝海绵状血管瘤安全、有效方法。

Objective To evaluate the therapeutic effect of three -dimensional conforrnal radiotherapy （3DCRT） for hepatic cavernous hemangiomas. Methods 43 cases of hepatic cavernous hemangiomas treated with three - dimensional conformal radiotherapy were retrospectively analyzed. 5 to 6 coplanar or noneoplanar fixed irradiation volume were set with the total dose of 3000 cGy and every dose 300 - 500 cGy. 6 to 10 times radiotherapy were finished in two weeks, Results The responsive rate of 43 patients was 100%. None of them died or had degression of liver function. Conclusion Three - dimensional conformal radiotherapy is curative, efficient and safe for patients with hepatic cavernous hemangiomas.
