Promoting the quality of health surveillance of workers exposed to wood dust, with particular care to NPSC, in the territory of the Health Agency of Florence

Wood dust can cause occupational-related naso-sinusal cancer, characterized by a latency period of about 40 years. The Tuscany Cancer Registry estimates that cases of NPSC are from 20-25 per year into the Region (33% related to wood dust). These neoplasms are surgically treatable at early-stage and, for this reason, a rapid endoscopic diagnosis is considered to be reasonably useful for prognostic issues. We used a questionnaire to investigate nasal symptoms and NOSQ and SOLAR questionnaires to highlight respiratory/skins diseases, and a spirometry for each worker. Subjects with a working-age of more than 15 years, and those that were positive to the questionnaire and/or to the medical history were were referred to a specialist in otolaryngology. The prevalence of endoscopic positive findings--detected especially in subjects with a working age of more than 15 years--confirms the significance of the problem.
