目的：探讨早期食管癌单纯放射治疗的效果。方法：１９７５年３月～１９７６年１０月对６４例早期中段食管癌进行了单纯放疗，放射源为６０Ｃｏ，采用常规三野照射，前野６ｃｍ×１５ｃｍ，背后二斜野５ｃｍ×１５ｃｍ，剂量为５０～７０Ｇｙ／５～７周。同时对患者的死亡原因进行了分析。结果：５、１０、１５和２０年生存率分别为７１．９％、４６．９％、３１．３％和１８．８％。长期生存者（１０年以上）死亡原因仍以本病为主。结论：放疗可以使患者长期生存，对早期中段食管癌放射治疗可作为首选治疗手段，同时对放疗后长期生存者应进行跟踪，发现问题及早处理。
Objective: To investigate the effect of simple radiotherapy for early esophageal cancer. Methods: Sixty-four patients with early stage esophageal cancer were treated with radiotherapy alone from March 1975 to October 1976. The radiation source was 60Co. The three fields were irradiated in the conventional way. The forward field was 6cm×15cm, the back two oblique fields were 5cm×15cm, and the dose was 50～ 70 Gy/5 to 7 weeks. At the same time, the cause of death of the patient was analyzed. Results: The 5-, 10-, 15-, and 20-year survival rates were 71.9%, 46.9%, 31.3%, and 18.8%, respectively. The cause of death for long-term survivors (more than 10 years) is still dominated by this disease. Conclusion: Radiotherapy can make patients survive for a long time. Radiotherapy for early middle esophageal cancer can be used as the first choice. At the same time, long-term survivors after radiotherapy should be tracked and problems should be solved early.
