【摘要】 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。更多还原

【Abstract】 To evaluate the curative effect of radiotherapy,64 patients with early stage esophageal carcinoma treated with radiotherapy from March 1975 to October 1976 were analysed. All patients were irradiated with 60Co,through three protals at dosage of DT50-70Gy/5-7 weeks. The survivals at 5-, 10-, 15-and 20-year were 71.9%, 46.9%, 31.3%and 18.8%respectively. Local recurrence and distant metastases were the major causes of failure for those patients who lived beyond 10 years. Radiotherapy is one of the effective ways for treating early stage mid-segment esophageal carcinoma. The authors suggest that follow-up of those patients who survived beyond 10 years is justified.更多还原
