[Objective] To analyze the radiotherapy effects of 15 cases of T2b glottic squamous cell carcinoma, review the literature, and discuss the methods to improve the survival rate of glottic squamous cell carcinoma at T2b stage. [Methods] From 1985 to 1994, Jiangsu Provincial Tumor Hospital and Changzhou Cancer Hospital treated T2b glottic squamous cell carcinoma in 15 cases. All of them were treated with simple radiation therapy, local 5cm × 6cm ~ 5cm × 7cm ono irradiation, irradiation dose DT7000cGy ~ 7500cGy, DT180cGy/time -200cGy/time, 53 days - 57 days. [Results] One case was lost to follow-up and the follow-up rate was 93 33%. The 5-year disease-free survival rate was 53 34%. [Conclusion] The radiotherapy effect of T2b glottic carcinoma is poor, and the ideal radiotherapy method is: about DT7000cGy, DT120cGy/time, twice a day (or DT>200cGy/time, once a day), ≤45 days
