摘要
目的：观察食管癌在低氧放疗中的放疗副作用和近，远期效果。方法：食管癌患者７２例，以配对原则随机分为低氧组和单照组，用＾６０Ｃｏγ线照射，低氧放疗方法为吸入１０．５％的低氧混合气２分钟后开始放疗，５分钟内完成治疗。结果：放疗后体重增加低氧组为２．３ｋｇ，单照组０．１９ｋｇ（Ｐ〈０．０５）。治疗后６个月，１的，３年，５年生存率低氧 是８６％、５６％、３３％、１１％，单照组是６９％、５０％、２５％、５．
Objective:To study decreasing the radiation side reaction,the short-term curetive effects and the surival rates of esophageal carcinoma with hypoxyradiotherapy.Metheds:72 patients with esophageal carcinoma were randomized into hypoxyradiotherapy group and single radiotherapy group.In the former,5min of 10.5% oxygen inhalation was carried out 2min before the radiation and in the later, 60 Co γ ray was used only.Result:The body weight after treatment was 2.3kg heavier than before in hypoxyradiotherapy group,0.19kg in single radiotherapy group (P< 0.05 ).The 0.5,1,3,5 surival rates 86%,56%,33%,11% in hypoxyradiotherapy group;69%,50%,25%,5.5% in single radiotherapy group (P>0.05).As to the cause of failure,there were 14 cases died from local relapse,8 cases died from distant metastasis.8 cases from focal relapse+distant metastasis in hypoxyradiotherapy group;there were 16,10,8,cases respectively in simple a group.Condusion:hypoxyradiotherapy radiotherapy can reduce radiation side reaction effectively and do not effect the surival rates.\;
