摘要 目的 评价陀螺旋转式立体定向放疗联合吉西他滨治疗局部晚期胰腺癌的疗效及安全性。方法37例局部晚期胰腺癌患者分为联合组18例和化疗组19例,联合组接受陀螺旋转式立体定向放疗联合吉西他滨单药化疗,化疗组仅接受联合吉西他滨单药化疗。化疗组具体方案为:吉西他滨1g/m2,静滴30分钟,第1、8、15天执行,28天为1个周期,共化疗2-6个周期。联合组放疗采用50%-60%等剂量曲线包绕计划靶区,全组靶区周边剂量3500-4200cGy,靶区周边中位处方剂量3800 cGy,280 cGy/次,5次/周,共13-15次。联合化疗首程采用同步化疗,具体方案为:吉西他滨0.5g/m2静滴30分钟,放疗治疗开始第1、8天执行。放疗结束3周后开始序贯化疗,方案同化疗组,共2-6个周期。所有患者随访4-24个月,以观察近、远期治疗效果及不良反应发生情况。结果 联合组和化疗组近期疗效分别为77.8%、33.3%,组间差异有显著性(P〈0.05)。联合组患者中位总生存时间为13.8个月,化疗组为9.5个月。联合组患者与化疗组毒副反应相近。结论 陀螺旋转式立体定向放疗联合吉西他滨治疗局部中晚期胰腺癌能提高局部控制率,延长总生存时间,不增加毒副反应。
