    Abstract:
    OBJECTIVES: To determine the clinical, histological, epidemiological and occupational data related to exposure to wood dust in a series of 100 nasal sinus malignant tumors. MATERIAL AND METHODS: We conducted a retrospective and descriptive study of cases diagnosed between 1st January 1981 and 31 December 2000, in the Auvergne region of France. Individual, medical, and occupational data were collected from a questionnaire completed by the patient (or the patient's family in case of death) and from the medical documents available. RESULTS: Forty-six cases (46 men), with an average age of 63+/-9.2 years [range, 43-82], had been exposed to occupational wood dust before the diagnosis. Fifty-four cases (30 men, 24 women), with an average age of 64.3+/-8.7 years [range, 40-96], had never been exposed. The average annual incidence increased, either for the total population or for the two subgroups distinguished on the basis of occupational exposure to wood dust. The majority of the patients presented different functional symptoms at the time of the diagnosis. For the 46 patients exposed to wood dust, the tumors were primarily ethmoid adenocarcinomas (92%). For the 54 non-exposed patients, the tumors observed were mainly epidermoid carcinomas (57%), then adenocarcinomas (15%). On the 46 patients exposed to wood dust, 85% were carpenters or cabinetmakers. For the majority of the patients, wood dust exposure started before the age of 20 (average age: 17+/-4.5) and the longest exposure began before 1981. The exposure time to wood dust before diagnosis was in the majority of cases greater than 20 years (mean exposure time: 37 years+/-11.4). Only 15% were exposed at the time of the diagnosis (mean time between the end of the exposure to the diagnosis was 11 years+/-2.8). Of the 54 non-exposed patients, no professional risk factor was evidenced. CONCLUSION: Epidemiologic data, such as the increasing incidence, and clinical and professional data, such as the occupational exposure to wood dust, were in agreement with the French and European literature. It is still probably too early to appreciate the effectiveness of prevention, established in France since 1980, on nasal sinus tumor incidence.
