    Abstract:
    Between 1974 and 1982, 78 primary esophageal squamous cell carcinomas were treated by external irradiation combined with additional intracavitary radium therapy. 50 to 60 Gy were given by external irradiation, and 5 to 20 Gy were delivered on the surface of the esophageal mucosa. The combined dose ranged from TDF 110 to 140 on the esophageal mucosa and TDF 95 to 120 at a depth of 5 mm from the esophageal mucosa. The 5-year survival rate was 19.3% by this combined radiotherapy alone. We conclude that the optimal dose of the combined therapy for esophageal cancer ranges from TDF 95 to 120 at a depth of 5 mm from the esophageal mucosa.
