There were 489 cases of laryngeal carcinoma with a 5-year survival rate of 72%. Stages I, II, and III received radiation therapy. In 287 cases of tongue cancer, the 5-year survival rate was 58%. There was almost no difference in the survival rate between stages I, II and III. Radiotherapy was the main method. All advanced cancers or recurrent cancers after stage I, II and III cancers were treated. Surgical treatment. In 83 cases of nasopharyngeal carcinoma, the 5-year survival rate was 41%, both of which were treated with radiotherapy. Those who had distant organ metastases were given chemotherapy. Oropharyngeal cancer in 112 cases, 5-year survival rate was 51%, in order to preserve the function is still based on radiation therapy, not suitable for extended resection in radiotherapy. Hypopharyngeal cancer
