目的比较食管癌外照射加腔内放射与单纯外照射治疗的生存率及副作用。材料与方法１９８９年２月～１９９２年７月１１０例经病理证实的食管中段癌，病变长度均小于７ｃｍ的放疗病例平均分成两组，Ａ组为单纯外照射组（对照组），Ｂ组为外照射加腔内放疗组（治疗组）。病例均无远处转移及锁骨上淋巴结转移。结果两组远期生存率无明显差别，近期副反应无明显差别，远期副反应及局部复发率Ａ组明显高于Ｂ组。结论两种治疗方法远期疗效无差别，外照射加腔内放疗，不仅减少局部复发率，还可减少全身反应，缩短治疗时间，不失为一种治疗食管癌的可行方法
Objective To compare the survival rate and side effects of esophageal cancer with external beam radiotherapy and external beam radiotherapy alone. Materials and Methods From February 1989 to July 1992, 110 patients with pathologically confirmed middle esophageal cancer and less than 7cm in length of radiotherapy were divided into two groups equally. Group A was a simple external irradiation group (control group), group B was External irradiation plus intracavitary radiotherapy group (treatment group). No cases of distant metastasis and supraclavicular lymph node metastasis. Results There was no significant difference in long-term survival between the two groups. There was no significant difference in recent side effects. The long-term side effects and local recurrence rate in group A were significantly higher than those in group B. Conclusion There is no difference in the long-term curative effect between the two treatment methods. External beam irradiation and intra-cavity radiotherapy not only reduce the local recurrence rate but also decrease the systemic reaction and shorten the treatment time, which may be a feasible method for the treatment of esophageal cancer
