本文分析了５３５例６５岁以上的老年食管癌放射治疗的远期疗效，全部病人随访均在５年以上，１、３、５年生存率分别为５０．５％、２０．７％、９．９％，病变部位对生存率不表现出明显的影响，病变长度对生存率有肯定的影响，即病变越短生存率越高且有统计学意义，总剂量对生存率的影响表现在大于７０００ｃＧｙ组生存率最低，故我们认为对老年食管癌的放疗不宜追求过高剂量，近期疗效与生存率呈平行关系即近期疗效好生存率较高。
This article analyzed the long-term efficacy of 535 elderly patients with esophageal cancer over the age of 65. All patients were followed for more than 5 years. The 1-, 3-, and 5-year survival rates were 50.5%, 20.7%, and 9. At 9%, lesion sites did not show a significant effect on survival. The lesion length had a positive impact on survival. The shorter the lesion was, the higher the survival rate was and the more statistically significant, the total dose had an effect on survival rate greater than 7000 cGy. The group had the lowest survival rate. Therefore, we believe that radiotherapy for esophageal cancer in the elderly should not be pursued with high doses. The short-term curative effect and the survival rate have a parallel relationship, that is, the short-term curative effect has a good survival rate.
