目的探讨单纯放射治疗老年食管癌患者的生存率及其影响因素。方法采用８ＭＶＸ射线体外照射，常规分割，总剂量４９．０～７９．５Ｇｙ，治疗２４０例老年人食管癌，回顾分析单纯放射治疗的疗效，并与文献报道非放射治疗老年人食管癌的疗效进行对照分析。结果全组１、３、５年生存率分别为６０．８％、１５．８％、１０．０％。老年人食管癌的单纯放射治疗疗效与非老年患者相似。病变长度在３～５ｃｍ者预后较好，Ｘ射线分型以蕈伞型预后为好，不同部位病变预后无明显差别。结论对体质尚好、能耐受的老年食管癌患者给予根治量（６０～７０Ｇｙ放射治疗），可获得较好的疗效
Objective To investigate the survival rate and its influencing factors of elderly patients with esophageal cancer treated with radiotherapy alone. Methods 8 MV X-rays were used for external irradiation. The total dose was 49.0 to 79.5 Gy. The treatment of esophageal cancer in 240 elderly patients was retrospectively analyzed. The efficacy of radiotherapy alone was reviewed, and the efficacy of non-radioactive elderly esophageal cancer was reported. Comparative analysis. Results The overall 1-, 3-, and 5-year survival rates were 60.8%, 15.8%, and 10.0%, respectively. The efficacy of radiotherapy alone for elderly esophageal cancer is similar to that of non-elderly patients. The prognosis was better when the lesion length was between 3 and 5cm. The X-ray classification was good for paralyzed umbrella type. There was no significant difference in the prognosis of lesions in different sites. Conclusion For patients with senile esophageal cancer who are in good condition and can tolerate the amount of radical treatment (60～70 Gy radiation therapy), better results can be obtained
