Stage III
Standard Treatment
• Supraglottis: Some centers use laryngectomy , but larynx and the voice can be preserved in about half the
cases if external beam radiotherapy is used and laryngectomy reserved for those in whom this treatment is
unsuccessful. Careful follow-up is vital since surgery is needed if the tumor persists or recurs. The lymph
nodes of the neck must be treated as part of the plan.
• Glottis: Surgery with postoperative radiotherapy, if necessary, for the primary site and/or positive lymph
nodes. Patients who refuse or cannot tolerate surgery are given radiation therapy . Again, many centers are
treating selected patients with radiotherapy as primary treatment. Careful follow-up
is vital, since surgery is needed if the tumor recurs.
• Subglottis: Primary radiotherapy may be tried, or laryngectomy, including also thyroidectomy and
tracheoesophageal lymph node dissection, all followed by radiotherapy. Some patients are not candidates for
surgery and are treated with radiotherapy alone, but surgical treatment may still be needed if there is a
recurrence .
Three-Year Survival 45 to 75 percent (supraglottis), 55 to 70 percent (glottis), no data for subglottis
