Survival rates in conservation surgery of the larynx.

Determinate survival rates have been compiled for 124 patients undergoing conservation surgery of the larynx at the University of Iowa between 1964 and 1970. In all patients treated with hemilaryngectomy, the five-year survival rate is 95%. When the anterior commissure is involved, the survival rate is 88%. In those patients with endolaryngeal lesions treated with supraglottic laryngectomy, the five-year survival rate is 68%, with only 42% surviving five years when the lesion is extralaryngeal. When histologically abnormal neck nodes are present, the overall five-year survival rate is 40%, compared with 87% when neck nodes are normal.
