为了探讨食管癌不同的食管轴向表现与放疗预后的关系，作者对１９９０年４月至１９９２年１２月期间外照射５０Ｇｙ的７１例食管癌的Χ线片形态和随访结果进行分析，结果发现，放疗前的食管轴向有以下表现，即扭曲、弧形弯曲、不规则弯曲和正常轴向４种形态，其中扭曲型的病例预后最差，其次是不规则弯曲型的病例。而放疗后食管轴向能恢复到正常的病例，在局部控制和生存情况方面均优于食管轴向不能恢复到正常的病例。提示了放疗后食管轴向表现与预后有一定关系。
In order to investigate the relationship between different esophageal axial manifestation and prognosis of radiotherapy for esophageal cancer, the authors analyzed 71 cases of esophageal cancer with external radiation of 50 Gy from April 1990 to December 1992 and analyzed the follow-up results. The esophageal axis before radiotherapy had the following manifestations: distorted, arcuately curved, irregularly curved, and normal axial. The distorted cases had the worst prognosis, followed by the irregularly curved ones. The axial esophageal can recover to normal after radiotherapy, and it is superior to local control and survival in cases where the esophageal axis can not return to normal. It is suggested that there is a relationship between the axial performance of the esophagus and prognosis after radiotherapy.
