摘要

BACKGROUND: Asbestos is a mineral fiber complex, that are directly related to the development of malignant pleural mesotheiioma (MPM) This compound is banned in countries such as North America, Europe and some Latin countries including our country, but by 2000, Mexico imported 27,000 tons, when it was known that asbestos is carcinogenic. OBJETIVE: To investigate whether the presence of asbestos fibers is associated with increased MPM in the Metropolitan Zone of Guadalajara (ZMG) METHODOLOGY 1.- MPM cases were collected from the database of the Division of Pathology, in the Western National Medical Center belonging to Mexican Social Secure Institute (IMSS) and the State Cancer Registry in Jalisco 2.- A review of the places of residence of MPM cases, locating the ZMG colonies that have as many tanks and asbestos shingles. 3. The roads with a flow greater than 10,000 cars per day were identified. RESULTS: For the period 1998 to 2009, the number of cases reported nationally MPM was 1730 and the sum of those reported by the State Cancer Registry and the Division of Pathology were 348, for the state of Jalisco. To this period there were 2769 deaths from MPM due to cancer of the trachea and lung, the latter are also associated with the presence of asbestos in the air. Colonies have a greater number of tanks and asbestos shingles are located in neighborhoods of Analco, Mexicalzingo, Mezquitan, San Juan de Dios and Santuario in the city of Guadalajara. For Zapopan region, colonies Vergel, Tabachines and Auditorio.. The busiest roads of the ZMG with a flow greater than 10,000 cars per day are: Lazaro Cardenas, Federalismo, Colon, Patria, Vallarta, Periferico, Javier Mina, Tesistan Road, Rio Nilo,and Mariano Otero. CONCLUSION: The widespread use of asbestos in water tanks, tiles and semi-metallic pads, has led the state of Jalisco to position in the first place nationally in deaths from MPM.
