Topographic distribution of laryngeal cancer

Abstract

The anatomic distribution of laryngeal cancer (LC) among the compartments of the larynx shows geographic variations. In the U.S., glottic cancers are more frequently seen, whereas most cases in the Mediterranean countries are supraglottic. We reviewed the anatomic sites of involvement in patients with laryngeal cancer seen in our clinic and at eight other university clinics between 1990 and 1994. The majority of cases were supraglottic cancers, accounting for 60% of all laryngeal tumors.
