Epidemiology of malignant pleural mesothelioma in the province of Sassari (Sardinia, Italy) A population-based report

Abstract

The aim of this population-based study was to analyze and describe the epidemiological characteristics and trends of malignant pleural mesothelioma in the province of Sassari (Sardinia, Italy), in the period 1992–2010. Data were obtained from the local tumor registry which makes part of a wider registry web, coordinated today by the Italian Association for Tumor Registries. The overall number of malignant pleural mesothelioma cases registered was 70. The male-to-female ratio was 4:1 and the mean age 65.1 years for males and 63.4 years for females. The standardized incidence rates were 1.2/100,000 and 0.3/100,000 and the standardized mortality rates 0.6/100,000 and 0.2/100,000 for males and females respectively. A trend to increase in incidence in recent years was evidenced. This trend seems to follow the general national tendency and it depends on a large diffusion of asbestos usage in the past, delayed legislative interventions and probably a cleaning strategy of residual contamination fonts to intensify. The relative 5 years survival was low, suggesting the necessity to further intensify research and cure methods for the treatment of this extremely aggressive disease.
