[Mesothelioma--asbestos in Lebanon: a problem to be considered].
To estimate the incidence of pleural mesothelioma and its relationship with the occupational and environmental exposure to asbestos in Chekka region. Between 1991 and 2000, 22 cases of malignant mesothelioma were diagnosed at Hôtel-Dieu de France Hospital. Eighteen cases were epidemiologically investigated. Fifteen among these 18 patients (83%) had a positive exposure history: exposure was occupational in 11 cases and environmental in 4 cases. The tumor was attributable to Eternit Company in 12 cases among the exposed 15 (80%). These 12 cases were secondary to occupational exposures in 8 and to environmental exposure in 4 cases. Mean latency period between exposition and diagnosis was 29 years. Fifteen patients died from the progression of their disease after a median survival of 8 months. The relationship between pleural mesothelioma and Eternit Company with the related occupational and environmental risk in Chekka region is obvious. The assessment of the incidence needs a national cancer registry. Despite the protective measures taken by the government since 1996, an increase in the incidence is suspected in the coming ten years because of the long latency period of the disease.
