title: Second primary cancer of the larynx in patients with lung cancer.
abstract: Synchronous or metachronous second primary malignancies of the lung are sometimes encountered in patients with laryngeal cancer while the occurrence of a laryngeal second primary following cancer of the lung is rare. A two-armed study was conducted. A prospective arm in which the larynges of 56 terminal lung cancer patients were examined, and a retrospective arm incorporating both a chart study of 126 terminal head and neck cancer patients (HNCP) and a computerized search of all hospital records of patients with laryngeal and lung cancers. No laryngeal malignancy was found in the lung cancer patients' group and no antedating pulmonary malignancy was recorded in the terminal HNCP. The computerized search of 1778 lung cancer patients and 213 laryngeal cancer patients also failed to demonstrate cases where the former preceded the latter. In conclusion. No second primary of the larynx was found in lung cancer patients. These results compare with reports of large databases where cancer of the larynx was found in a negligible percentage of lung cancer survivors and theories explaining this are discussed.
