Radiation Therapy in The Treatment of T₁ Glottic Cancer

Radiation therapy is generally considered to be the treatment of choice in T₁ glottic cancer, maninly because of preservation of voice function and its local control rate is comparable to that of surgery. Failures from radiation therapy can be ultimately salvaged by surgery. A retrospective analysis of the treatment of 25 patients with T₁ glottic cancer seen at the Y onsei Cancer Center from 1980 to 1984 is presented. Radiation dose to the target volume varied from 6400 to 7000 cGy in 6-7 weeks. The local control rate is 84%. Four patients had primary failure and three of these patients had salvage surgery. Of the 3 patients who had salvage surgery, 2 were cured and aonther one was died with progression of the disease. 5-year acturial and disease free survival rate are 91.1%, 78.0% respectively.
