本文比较了食管癌各种治疗方法的远期疗效，其中单纯放疗组的１、３、５年生存率分别为５０．０％，２０．５％和１８．３％，明显低于手术组和放疗加手术组。手术加放疗组的１年生存率亦明显高于单纯放疗组。分析研究影响食管癌放射治疗疗效的各种因素。建议放射治疗要根据周围组织浸润范围及区域淋巴结转移情况，适当扩大照射野的宽度，并对提高食管癌远期疗效的治疗问题进行了讨论。
This article compares the long-term efficacy of various treatments for esophageal cancer. The 1-, 3-, and 5-year survival rates of the radiotherapy alone group were 50.0%, 20.5%, and 18.3%, respectively, which were significantly lower than those of the surgery group. Radiotherapy plus surgery group. The one-year survival rate was also significantly higher in the surgery plus radiotherapy group than in the radiotherapy alone group. Analysis of various factors affecting the efficacy of esophageal cancer radiotherapy. It is suggested that radiation therapy should appropriately expand the width of the irradiation field according to the extent of infiltration of the surrounding tissue and regional lymph node metastasis, and discuss the treatment of esophageal cancer to improve its long-term efficacy.
