          Abstract

          RESUMEN Se estimó la tasa de mortalidad por mesotelioma y su distribución sociodemográfica y temporal en Argentina para el período 1980-2013 con datos del Sistema de Estadísticas Vitales del Ministerio de Salud de la Nación. Se encontraron 3.259 defunciones por mesotelioma, lo que resulta en una tasa de mortalidad estandarizada por edad de 3,1/1.000.000 en 1980 y de 5,7/1.000.000 en 2013, con un aumento promedio del 84,1% en 34 años. El incremento de la tendencia fue más claro a partir de 1997. En todos los años, la tasa de mortalidad fue mayor en hombres que en mujeres. Los resultados sugieren antecedentes de exposición al asbesto en el pasado. Aparentemente, la exposición predominante fue la ocupacional, más común entre los hombres que concentraron los casos. Se recomiendan acciones dirigidas a hacer más efectiva la prohibición ya en vigor y la vigilancia en salud orientada a los ambientes de trabajo, trabajadores previamente expuestos y la población en general.

          ABSTRACT Mesothelioma mortality and its socio-demographic and temporal patterns in Argentina from 1980 to 2013 were estimated using data from death certificates obtained from the Vital Statistics System of Argentina’s National Ministry of Health. There were 3,259 mesothelioma deaths corresponding to an age-adjusted mortality of 3.1/1,000,000 in 1980 and 5.7/1,000,000 in 2013, an average increase of 84.1% in 34 years. This raising trend became clearer after 1997. Males had higher mortality estimates compared with women in every year of the series; these findings suggest past exposure to asbestos. It is plausible that the asbestos exposure was mostly occupational, which is more common among men. Actions related to reinforcing the asbestos ban already in place and strengthening health surveillance directed at workplaces, previously exposed workers, and the population in general are recommended.

          Global Magnitude of Reported and Unreported Mesothelioma

          Background Little is known about the global magnitude of mesothelioma. In particular, many developing countries, including some with extensive historical use of asbestos, do not report mesothelioma. Objectives We estimated the global magnitude of mesothelioma accounting for reported and unreported cases. Methods For all countries with available data on mesothelioma frequency and asbestos use (n = 56), we calculated the 15-year cumulative number of mesotheliomas during 1994–2008 from data available for fewer years and assessed its relationship with levels of cumulative asbestos use during 1920–1970. We used this relationship to predict the number of unreported mesotheliomas in countries for which no information on mesothelioma is available but which have recorded asbestos use (n = 33). Results Within the group of 56 countries with data on mesothelioma occurrence and asbestos use, the 15-year cumulative number of mesothelioma was approximately 174,300. There was a statistically significant positive linear relation between the log-transformed national cumulative mesothelioma numbers and the log-transformed cumulative asbestos use (adjusted R 2 = 0.83, p < 0.0001). Extrapolated to the group of 33 countries without reported mesothelioma, a total of approximately 38,900 (95% confidence interval, 36,700–41,100) mesothelioma cases were estimated to have occurred in the 15-year period (1994–2008). Conclusions We estimate conservatively that, globally, one mesothelioma case has been overlooked for every four to five reported cases. Because our estimation is based on asbestos use until 1970, the many countries that increased asbestos use since then should anticipate a higher disease burden in the immediate decades ahead.

            Asbestos: use, bans and disease burden in Europe

            Abstract Objective To analyse national data on asbestos use and related diseases in the European Region of the World Health Organization (WHO). Methods For each of the 53 countries, per capita asbestos use (kg/capita/year) and age-adjusted mortality rates (deaths/million persons/year) due to mesothelioma and asbestosis were calculated using the databases of the United States Geological Survey and WHO, respectively. Countries were further categorized by ban status: early-ban (ban adopted by 2000, n = 17), late-ban (ban adopted 2001–2013, n = 17), and no-ban (n = 19). Findings Between 1920–2012, the highest per capita asbestos use was found in the no-ban group. After 2000, early-ban and late-ban groups reduced their asbestos use levels to less than or equal to 0.1 kg/capita/year, respectively, while the no-ban group maintained a very high use at 2.2 kg/capita/year. Between 1994 and 2010, the European Region registered 106 180 deaths from mesothelioma and asbestosis, accounting for 60% of such deaths worldwide. In the early-ban and late-ban groups, 16/17 and 15/17 countries, respectively, reported mesothelioma data to WHO, while only 6/19 countries in the no-ban group reported such data. The age-adjusted mortality rates for mesothelioma for the early-ban, late-ban and no-ban groups were 9.4, 3.7 and 3.2 deaths/million persons/year, respectively. Asbestosis rates for the groups were 0.8, 0.9 and 1.5 deaths/million persons/year, respectively. Conclusion Within the European Region, the early-ban countries reported most of the current asbestos-related deaths. However, this might shift to the no-ban countries, since the disease burden will likely increase in these countries due the heavy use of asbestos.

              Continuing increase in mesothelioma mortality in Britain.

              Mesothelioma is closely related to exposure to asbestos, and mesothelioma mortality can be taken as an index of past exposure to asbestos in the population. We analysed mesothelioma mortality since 1968 to assess the current state of the mesothelioma epidemic, and to predict its future course. We found that rates of mesothelioma in men formed a clear pattern defined by age and date of birth. Rates rose steeply with age showing a very similar pattern in all five-year birth cohorts. By date of birth, rates increased from mid-1893 to mid-1948, and then fell. Relative to the 1943-48 cohort, the risk for the 1948-53 cohort is 0.79 and for the 1953-58 cohort 0.48. Despite these falls, if the age profile of rates for these cohorts follows the pattern of past cohorts, their predicted lifetime mesothelioma risks will be 1.3%, 1.0%, and 0.6%. Combining projections for all cohorts results in a peak of annual male mesothelioma deaths in about the year 2020 of between 2700 and 3300 deaths. If diagnostic trend is responsible for a 20% growth in recorded cases every 5 years--an extreme but arguable case--and if this trend has now ceased, the peak of annual male deaths will be reduced to 1300, reached around the year 2010. Analysis of occupations recorded on death certificates indicate that building workers, especially plumbers and gas fitters, carpenters and electricians are the largest high-risk group. These data indicate that mesothelioma deaths will continue to increase for at least 15 and more likely 25 years. For the worst affected cohorts--men born in the 1940s--mesothelioma may account for around 1% of all deaths. Asbestos exposure at work in construction and building maintenance will account for a large proportion of these deaths, and it is important that such workers should be aware of the risks and take appropriate precautions.
