Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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).
