Introduction: Questions concerning under-reporting of occupational diseases (OD) linked to asbestos exposure are regularly voiced in France. Monitoring of the French multicenter Asbestos-Related Disease Cohort (ARDCO), which ensures post-occupational medical surveillance of subjects having been exposed to asbestos, provides information on (1) the medico-legal steps taken following screening by computed tomography (CT) for benign thoracic diseases, and (2) recognition of OD as a causal factor in malignant diseases., Methods: OD recognition - and possible compensation - was analyzed in July 2021 among 13,289 volunteers in the cohort recruited between 2003 and 2005., Results: Fifteen percent of the subjects in the cohort were found to have at least one recognized asbestos-related OD (78.2% benign pleural disease, 10.3% asbestosis, 14.2% lung cancer, and 6.0% mesothelioma). Only 58% of pleural plaques reported by the radiologist who performed the CT resulted in their recognition as ODs. On a parallel track, 88.7% of the mesotheliomas identified based on French National health insurance data and 46.9% of lung cancers were recognized as ODs., Conclusions: This study confirms the feasibility of a system designed to facilitate recognition, leading to possible compensation, of asbestos-related occupational diseases. The system could be improved by better training of the medical actors involved., (Copyright © 2024 SPLF. Published by Elsevier Masson SAS. All rights reserved.) more...

Introduction: In France, long-term follow-up after occupational exposure to asbestos is recommended. This study looked at the psychological consequences in the longer term following a CT-scan, in particular the impact of having received compensation for an occupational disease., Methods: As part of an asbestos post-exposure survey study (APExS), volunteers from Normandy were asked to complete self-assessment questionnaires about their psychological condition at different points during follow-up, including a psychological questionnaire before, then 6 months, and finally 18 to 24 months after their chest CT-scan. Information collected from 622 individuals were analyzed based on information provided as to the result of the screening and whether they had received compensation for having an occupational disease., Results: The identification of an occupational disease eligible for compensation is associated with a long term increase in psychological distress. The impact of psychological state during follow-up is greater in men who reported receiving occupational disease compensation. The discovery of an asbestos-related disease during the screening is associated with a negative perception of general health and an increase in psychological distress., Conclusion: The receipt of compensation of an occupational disease does not seem to compensate for the negative psychological impact related to the discovery of a disease during the asbestos post-exposure follow-up., (Copyright © 2019 SPLF.

As long as the value of screening for cancers related to asbestos is not proven in the population at risk, the medical benefits of follow-up post-professional exposure remain uncertain and the only justification is to answer the questions of anxious retired workers concerning the consequences of their past-exposure and to provide compensation for any abnormalities that are demonstrated. In this country, to answer the questions posed in the title of this contribution in the case of pathologies related to asbestos, it is necessary, after verifying the fact and the level of exposure, to identify the pleural or pulmonary fibrosis and, above all, the pleural plaques, which constitute the essential lesions currently screened for. Thoracic CT scanning without contrast is the examination of choice to achieve this objective. There are, however, two significant problems. On one hand there is a high incidence of pulmonary micronodules, the necessary surveillance of which requires subsequent scans, leading to increased irradiation and anxiety. On the other hand the diagnostic uncertainty concerning discrete lesions is a source of confusion for the persons followed-up. There are, at present, neither scientific criteria to determine the optimum frequency of examination nor any arguments for replacing the pragmatic proposals of the consensus conference of 1999. It is important, therefore, to provide a medical assessment appropriate to the symptoms and anxiety expressed by a person previously exposed to asbestos. Overall it is necessary to question the benefit to the exposed person, in terms of quality of life, of a regular search for lesions that would usually be asymptomatic if not identified. Would it not be more judicious and more equitable to compensate persons whose past-exposure is sufficient to increase significantly their risk of cancer independently of the presence of benign abnormalities., (Copyright © 2011 SPLF.

Among the non malignant diseases related to asbestos exposure, pleural plaques are the most frequent. Pleural effusion and diffuse pleural thickening, as well as asbestosis, are uncommon nowadays in asbestos-exposed screened populations. Despite the absence of any useful treatment, accurate diagnoses of these diseases are needed for two reasons: on the one hand in order to save patients from anxiety related to diagnostic and prognostic discrepancies, and on the other hand in order to ensure a proper attribution of the high social and financial compensations which are provided in France for asbestos affected patients. CT scan of the thorax is the most sensitive and specific tool for a precise diagnosis of these lesions, but it often displays minute abnormalities which may give rise to major diagnostic discordances, owing to the absence of any tomodensitometric reference in populations proved to be free from any asbestos exposure. There is a need to seek for a suitable standardization of imaging technique and interpretation, for a consensus in the characterization of CTscan abnormalities that warrant compensation, and for a careful medico-psychologic assistance for patients affected by asbestos-related benign diseases. more...
