目的从Ｘ线角度对照观察导管化疗加放疗及Ｘ刀治疗晚期食管癌后的疗效．方法晚期食管癌６０例，其中经导管化疗加放疗３０例（综合组），Ｘ刀治疗３０例（Ｘ刀组）．各治疗组前、中、后各摄食管Ｘ线吞钡片充盈、粘膜象各一张，以观察疗效．结果治疗后总生存率，综合组１，３，５ａ分别为７３％，４４３％，２７３％．Ｘ－刀组由于开展近２ａ２ｍｏ，除一例治疗后形成食管气管瘘死亡外，其余仍在观察．治疗效果和病变长度、Ｘ线分型、病理类型及有否转移有关．Ｘ刀治疗组治疗后食管狭窄率明显高于综合组．通过本组病例的Ｘ线对照分析Ｘ线吞钡观察晚期食管癌治疗前后的改变情况可作为判断预后的标准之一．结论从Ｘ线角度观察导管化疗加放疗治疗晚期食管癌疗效好于Ｘ－刀治疗，且Ｘ刀治疗狭窄率明显增高 3. Objective To observe the effect of radiotherapy combined with radiotherapy and X - knife after advanced esophageal carcinoma from X - ray perspective. Methods 60 cases of advanced esophageal cancer, including 30 cases of transcatheter chemotherapy plus radiotherapy (comprehensive group), X knife treatment of 30 cases (X- knife group). Before, during and after each treatment group, the feeding tube was filled with X-ray swallowing tablets and the mucous membranes were observed one by one to observe the curative effect. Results The overall survival rate after treatment was 1, 3, and 5a in the comprehensive group, 73%, 44. 3%, 27% and 3%, respectively. The X-knife group was still under observation for nearly 2a2mo, except one case of esophageal tracheal death after treatment. The therapeutic effect is related to the length of the lesion, X-ray type, pathological type and whether there is metastasis. The incidence of esophageal stenosis was significantly higher in the X-knife treatment group than in the comprehensive group. Through X-ray contrast analysis of X-rays in this group of patients to observe the changes before and after treatment of advanced esophageal cancer can be used as one of the criteria to determine the prognosis. Conclusion From the perspective of X-ray, the efficacy of catheterized chemotherapy plus radiotherapy for advanced esophageal cancer was better than that of X-knife treatment, and the X-knife treatment significantly increased the stenosis rate.
