摘要 目的评价食管癌超分割放射治疗的疗效及放射反应。方法100例食管癌随机分为2个组:常规分割放射治疗组50例,1次/a,2Gy/次,5次/周,总剂量66Gy/33F,6.6W;超分割放射治疗组50例,2次/a,1.15Gy/次,间隔6d以上,10次/周,总剂量75.9Gy/66F,6.6W。结果两组的放射毒性发生率差异无统计学意义(P>0.05)。超分割组和常规分割组的2,4,6,8年局控率分别为57.1%,52.6%,47.9%,42.2%和34.6%,29.2%,25.4%,21.6%;两个组比较差异有统计学意义(χ2=6.452,P<0.05)。超分割组和常规分割组的2,4,6,8年生存率分别为30.1%,24.2%,22.8%,18.5%和22.4%,18.5%,14.6%,12.1%;两个组比较差异无统计学意义(χ2=3.174,P>0.05)。结论食管癌超分割放射治疗能提高局控率,放射毒性无明显加重。
