食管癌外照射加腔内后装治疗４０例与单纯外照射６０例。腔内治疗在外照射肿瘤量５０－６０Ｇｙ后进行，４－６Ｇｙ／次周，治疗２－３次，总量６０－６５Ｇｙ。单纯外照射总量也达６０－６５Ｇｙ／６－７周。外照射加腔内组ＣＲ７５％、ＰＲ２２．５％、ＮＲ２．５％，一年生存率８０％。单纯外照射组分别为４３％，５２％，５％，５６．７％。提示外照射加腔内治疗能提高食管癌的生存率及生存质量。腔内治疗在食管癌的根治性放疗中成为不可缺少的手段。 Esophageal cancer plus external cavity plus posterior treatment of 40 cases and 60 cases of external irradiation alone. Intraluminal treatment was performed after external irradiation of 50-60 Gy of tumor, 4-6Gy/week, treatment 2-3 times, total 60-65Gy. The total amount of external exposure alone also reached 60-65 Gy/6-7 weeks. External irradiation plus intraluminal group CR75%, PR22.5%, NR2.5%, one year survival rate of 80%. The external exposure group was 43%, 52%, 5%, and 56.7%, respectively. Tip External irradiation and endoluminal treatment can improve the survival rate and quality of life of esophageal cancer. Endovascular treatment has become an indispensable means for radical radiotherapy for esophageal cancer.
