Whether chemotherapy is needed after laryngeal cancer total excision surgery is considered in conjunction with the stage of laryngeal cancer and whether there is cancer residue in the surgical stump. If the laryngeal cancer is in early stage, adjuvant chemotherapy is not needed; if it is in middle or late stage and there is cancer residue after surgery, adjuvant chemotherapy is usually needed. Patients with early stage laryngeal cancer usually do not need adjuvant chemotherapy after total excision of laryngeal cancer without the risk of recurrence. For patients with intermediate stage laryngeal cancer, it is necessary to take into account the presence of lymph node metastasis and pathological stage to determine whether adjuvant chemotherapy is needed. For patients with advanced laryngeal cancer, adjuvant chemotherapy is usually recommended after surgical treatment. Overall, the specific treatment plan of patients usually has individual differences, so they need to go to oncology department, ENT department, etc., and be evaluated by doctors before they can formulate individualized treatment plan. During the course of treatment, patients need to undergo regular follow-ups to monitor the effectiveness of the treatment and to assess whether the condition has worsened.
