A series of 90 esophageal carcinoma patients.They were irradiated by randomomized methord.45 cases were received large dosage(60 Gy/5wk) fraction irradiation and other received rular dosage(70Gy/7wk) fraction erradiation.All patients had been followed up in september,1992.The result indicated that the survival rate of and 2 year in large dosage group was much better than in rular dosage group.The main cause of failure was local uncontrol and recover and it was lower in the large dosage group than in the another.We suggested the radiation of Esophageal carcioma had better take large dose fraction irradiation.
