In a 20 year period (1974-1995), 3451 patients with bronchogenic carcinoma were observed. Retrospective analysis of these cases allowed to study the relationship between primary pulmonary malignancies and laryngeal tumours. In 32 patients synchronous or metachronous carcinoma of the larynx and lung were found. All laryngeal tumours were curable but only fifteen of these second primary lung tumours were successfully treated. None of unresected patients survived beyond 2 years.
