N2 - From 1975 to 1987, 170 unresectable esophageal carcinomas were curatively irradiated. Ninety-eight cases were treated with conventional fractionation and a small field, 32 cases to a large T-shaped field, and 40 cases with conventional 50-60 Gy doses followed by 14-28 Gy of low-dose rate telecobalt therapy (LDRT: 1 Gy/hr, 4-7 Gy/day). The one-year, three-year and five-year survival rates in all cases were, 33%, 9% and 5%, and in LDRT groups, 37%, 15% and 8%, respectively. The survival rate and the local cure rate in the LDRT group were a little better than the others. The prognosis of T-shape group was proven to be the same as conventional group.
