Combined Therapy of CO₂ Laser and Irradiation for T1, T2 Laryngeal Cancer

Abstract

Combined therapy of CO₂ laser and irradiation (LINAC 60 Gy) was performed in cases of T1 and T2 laryngeal cancer. We studied the prognosis and the postoperative vocal function in these patients followed for one year. Twenty-two of twenty-three patients are alive without cancer, while one patient died of other cause. The preservation rate of larynx was 95.5% (21/22 cases). CO₂ laser therapy and radiation therapy, which have previously been used for the treatment of laryngeal cancer, were utilized more widely in the present study. The good results appeared to be obtained.
