食管癌是常见的恶性肿瘤之一，病人就诊时绝大多数已属中、晚期，失去手术机会。放射治疗是首选治疗方法，但5年生存率仅徘徊在6％～17％［1］。为探讨食管癌放射治疗后长期生存的相关因素，本文对放射治疗后生存10年以上的16例回顾性分析如下。临床资料一、一般资料：本组16例 Esophageal cancer is one of the most common malignancies. The vast majority of patients at the time of treatment are in the middle and late stages and lose the chance of surgery. Radiation therapy is the preferred treatment, but the 5-year survival rate is only 6% to 17% [1]. To investigate the long-term survival of esophageal cancer related factors, this article retrospective analysis of 16 cases of survival after radiotherapy for more than 10 years are as follows. Clinical data I. General information: 16 cases in this group
