[Determination of groups at risk for laryngeal tumors]

A procedure for development of an adequate screening program for detecting precancer and cancer of the larynx was elaborated on the basis of outpatient charts and regular check-up data. Patients with laryngeal neoplasia were included into the "cancer" group (47), those with hyperplastic laryngitis--"precancer" (189) and disease-free subjects--into the "normal" group (260). Cancer suspects as identified by the procedure should be referred to the otolaryngologist for closer examination.
