[Early cancer detection in the oro-pharyngo-laryngeal area: analysis of a regional screening project (author's transl)].

During a six months lasting screening project 6866 persons were examined free of cost. Inspection of the mouth, endoscopy of the naso-hypopharynx and larynx with the Wolf-endoscope after v. Stuckrad, and palpation of the neck were included. Every sixth person required further diagnosis or treatment. Precanceroses were found in almost 3%, and up to now malignomas were found in 0.3% of the screened persons. Among these 14 cases of cancer were 9 carcinomas of the larynx. This comparatively high percentage of precanceroses and cancer favors the endoscopic screening of patients with organ-related symptoms and of high risk groups.
