摘要 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。

Abstract Objective To analyzethe survival of elderly esophageal cancer patients treated by radiotherapy. Methods Two hundredand forty elderly esophageal cancer patients, aged 60-93, male 170 (70.8%), female70(29.2%), received high energy X-ray external radiotherapy. Radiation doses were49.0-79.5Gy with conventional fractions. Results The 1-,3-and 5-year survival rates were 60.8%, 15.8%,and 10.0%.Theprognosis of those patients with the tumor length within 3～5 cm and the fungating type were better than the rest. Conclusions Thetreated results of elderly esophageal cancer patients were not so bad. For elderlypatients in good conditions and endurable to the treatment, the radical dose 60-70Gy, oreven above 70Gy may be given.
