Adenocarcinoma and wood.
The relation of adenocarcinoma of the facial sinuses and exposure to wood dust has been recognized for 20 years. As the tracheobronchial mucosa is similar to that lining the sinuses, a link between bronchial adenocarcinoma and wood dust exposure has been postulated. To test this hypothesis, a case-control study was conducted, based on all the histologically proven cases of adenocarcinoma of the lung reported to the tumor registry of the Doubs region of France from 1978 to 1985 and random population controls matched for age and residence. A questionnaire on occupational exposure and tobacco consumption was completed by 53 cases and 160 controls. Exposure to wood was similar for both groups, the crude relative risk (odds ratio) being 1.06; adjustment for tobacco consumption did not modify this value. Exposure to wood dust does not seem to be an occupational risk factor in the genesis of bronchial adenocarcinoma.
