Stage II 
Standard Treatment 
• Supraglottis: External beam radiation therapy is used for smaller tumors, which preserves the voice. The
  lymph nodes should be included in the radiotherapy field. Another option is a supraglottic laryngectomy or
  total laryngectomy, depending on the location of the lesion and the status of the patient.   Care is needed when
  selecting this option to ensure adequate lung and swallowing function after surgery. 
      If a patient is not cured by radiation given as the primary treatment, surgery is then used in an attempt to
  cure. If surgery is the primary treatment, postoperative radiotherapy is used if tumor is found in surgical
  margins or lymph nodes in the neck.
• Glottis: Radiotherapy or surgery (partial or total laryngectomy).
• Subglottis: Radiotherapy (with voice preservation), with surgery reserved for patients whose tumors recur or
  those who might not have adequate follow-up evaluation.

Five-Year Survival  55 to 65 percent (supraglottis), 60 to 80 percent (glottis), 30 to 40 percent (subglottis)
