[Result of radiotherapy for esophageal cancer--radical radiotherapy combined with intracavitary radium irradiation]

Between 1974 and 1980, 61 primary esophageal squamous cell carcinoma were treated by external irradiation combined with additional intracavitary radium therapy. The esophageal primary control rate was 36% (22/61) and the 5-year survival rate was 24.7%. We believe that external radiation therapy followed by additional intracavitary radium irradiation produces good results.
