Patients with advanced laryngeal cancer generally cannot undergo surgery, and the main treatment measures are radiotherapy and chemotherapy, which can shrink the tumor and reduce part of the patient’s pain. Some patients are not particularly sensitive to radiotherapy and chemotherapy, and the efficacy is poor. At this time, only late palliative symptomatic treatment is available, that is, to deal with the patient’s situation, such as the patient has difficulty in breathing, tracheotomy may be performed, and painkillers are applied when the patient is in pain. If the compression of esophagus causes difficulty in swallowing, a nasal feeding tube can be inserted to relieve the patient’s pain and improve the patient’s survival quality. The tumor of advanced laryngeal cancer patients may compress or invade the surrounding adjacent organs and produce corresponding symptoms, as follows: 1. if the tumor compresses or invades the trachea, the patient will have difficulty in breathing; 2. if the tumor compresses the esophagus, the patient will have difficulty in swallowing; 3. if the tumor compresses large blood vessels, the patient will have head and facial swelling, and may even have hemorrhage; 4. because the tumor is relatively large and compresses the surrounding nerves, the patient will have pain.
