Treatment by Stage 
Stage I 
Standard Treatment 
• Supraglottis: External beam radiotherapy alone or supraglottic laryngectomy . There are frequent problems
  with the functioning of the larynx after the latter procedure.
• Glottis: Radiotherapy, which provides both cure and good voice quality in most patients. Selected patients
  with small (T1) superficial lesions can have a portion of the vocal cord removed. Partial or sometimes total
  laryngectomy may be done depending on the tumor's location and size. Laser excision is under clinical
  evaluation.
• Subglottis: Radiotherapy alone, with surgery used for recurrence .

Five-Year Survival  75 to 95 percent
