Application of Guidelines for Medico-professional Supervision of Workers Exposed to Carcinogenic Action of Wood Dust: CERBois Cohort

Completed

• Conditions: Exposition to Wood Dust
• Interventions: Procedure: Nasofibroscopy

• Registration Number: NCT02884232
• Lead Sponsor: Central Hospital, Nancy, France

Brief Summary

The purpose is to evaluate feasibility of medical supervision of professionally active asymptomatic wood workers with questionnaires and nasofibroscopy.

Secondary purposes are:

* Feasibility evaluation of identification of former and actual professional expositions to wood dust and to various naso-sinusal carcinogenics in case of co-expositions (formaldehyde, chrome, nickel, leather)

* Description of abnormal symptoms identified by occupational doctor and needing an otorhinolaryngology test

* Description of results and examinations induced by nasofibroscopy in symptomatic or asymptomatic individuals: counting of naso-sinusal adenocarcinoma cases

* Evaluation of participation of workers retiring in 2 years after inclusion to medical supervision program

* Evaluation of information flow among different players

* Assessment of costs induced by this targeted screening: direct medical costs (screened pathologies, induced additional examinations...) and indirect costs for company (duration of worker absence for transfer, medical and additional examinations).
