【摘要】 目的 探讨治疗计划系统(TPS)术中实时计划对CT引导下125I放射性粒子治疗腹膜后淋巴结的必要性及可行性。方法 回顾性分析2013年1月至2015年12月行CT引导下125I放射性粒子治疗的20例腹膜后淋巴结转移癌患者的相关资料,其中10例行TPS术中实时计划指导(A组),10例未行TPS术中实时计划指导(B组),两组患者均行术前计划及术后质量验证。比较A、B两组手术前后90%靶体积的最小吸收剂量(D90)误差百分比、90%处方剂量覆盖的体积占靶体积的百分比(V90)误差百分比、100%处方剂量覆盖的体积占靶体积的百分比(V100)误差百分比、150%处方剂量覆盖的体积占靶体积的百分比(V150)误差百分比的差异。结果 A组手术前后的D90、V90、V100、V150的误差百分比分别为(-1.30±6.80) Gy、(-0.60±2.10)%、(-0.47±2.70)%、(89.60±282.00)%;B组手术前后的D90、V90、V100、V150的误差百分比分别为(-9.33±46.00) Gy、(11.50±13.70)%、(-13.40±15.90)%、(10.37±2.00)%。两组各参数相比较,其中D90、V90、V100误差百分比差异有统计学意义(P<0.05)。两组V150的误差百分比无统计学差异(P=0.247)。结论 术中实时计划指导可显著提高粒子植入前后靶区剂量的一致性,使剂量分布更加合理,对腹膜后淋巴结转移癌125I放射性粒子治疗的规范化具有重要价值。
