根治性手术结合术前或术后放疗对选择性食管癌病人的5年生存率不超过10%,单纯体外放疗的效果亦不理想,主要原因是淋巴结及远处转移率高,尤其是局部控制困难.采用腔内放疗作为体外照射的追加疗法,以提高食管癌的局部控制效果,分析其疗效以及在食管癌治疗中的价值.自1974～1988年,对体外照射后一般情况较好且能够插入直径为1cm外管的161例病人行腔内放疗.男139例,女22例.年龄17～88岁,平均64岁.肿瘤长度1.1～15.0cm,平均6.0cm.按1978年UICC TNM分期,Ⅱ期71
Radical surgery combined with preoperative or postoperative radiotherapy for patients with selective esophageal cancer has a 5-year survival rate of no more than 10%. The effect of simple external radiotherapy is also unsatisfactory, mainly due to high lymph node and distant metastasis rate, especially local control. Difficulties. Intracavitary radiotherapy is used as an adjunctive therapy for extracorporeal irradiation to improve the local control of esophageal cancer and to analyze its efficacy and value in the treatment of esophageal cancer. From 1974 to 1988, it was generally better and able to Into a luminal tube with a diameter of 1 cm, 161 patients underwent endoluminal radiotherapy. 139 males and 22 females. Aged 17 to 88 years, mean 64 years. Tumor length 1.1 to 15.0 cm, average 6.0 cm. According to 1978 UICC TNM staging, Phase II 71
