Laryngeal cancer is a type of malignant tumor in otolaryngology, divided into primary and secondary types. Secondary tumors refer to malignant tumors that have metastasized from other parts of the body, which are relatively rare; while primary tumors originate in the laryngeal area, with squamous cell carcinoma being the most common. For early-stage laryngeal cancer patients, it is generally necessary to detect and treat the disease early. Minimally invasive surgery using methods such as carbon dioxide laser can be used to remove the tumor, and patients can be cured. However, for hypopharyngeal cancer and late-stage tumors, due to the biological characteristics of the patients, early metastasis is common, making complete recovery difficult. Recurrence is also possible. Therefore, timely treatment is necessary, and postoperative radiotherapy and chemotherapy are needed to further augment treatment, aiming to extend the patient's survival period as much as possible.
