目的了解云南省大姚县2007—2012年恶性肿瘤,特别是胸膜间皮瘤病例的死亡情况,分析其与青石棉暴露之间的关系。为当地政府制定科学合理的青石棉污染防治措施提供依据。方法收集大姚县2007—2012年恶性肿瘤病例死亡情况,计算各年恶性肿瘤死亡率,并计算各类癌症标准化死亡率比(SMR),同时分析胸膜间皮瘤死亡病例在大姚县各乡镇分布情况。结果大姚县肝癌SMR为1.23;胸膜间皮瘤SMR达到5.63;2010—2012年胸膜间皮瘤死亡率高于2007—2009年(P<0.01)。胸膜间皮瘤的死亡人数分布与青石棉污染区分布基本一致。结论大姚县胸膜间皮瘤死亡率较上世纪有所下降,当地应继续加强青石棉的综合治理。
Objective To investigate the deaths of malignant tumors, especially pleural mesothelioma, from 2007 to 2012 in Dayao County, Yunnan Province, and to analyze the relationship between the exposure and the exposure to crocidolite. For the local government to develop scientific and rational crocidolite pollution prevention measures to provide the basis. Methods The mortality of malignant tumor from 2007 to 2012 in Dayao County was collected. The mortality of malignant tumor in each year was calculated, and the standardized mortality ratio (SMR) of various types of cancer was calculated. At the same time, the death cases of pleural mesothelioma were analyzed in towns and villages of Dayao County Distribution. Results The SMR of hepatoma in Dayao County was 1.23. The SMR of pleural mesothelioma was 5.63. The mortality rate of pleural mesothelioma in 2010-2012 was higher than that in 2007-2009 (P <0.01). The distribution of pleural mesothelioma deaths and the distribution of crocidolite contaminated areas are basically the same. Conclusion The mortality rate of pleural mesothelioma in Dayao County has dropped compared with the last century, and the local should continue to strengthen the comprehensive management of crocidolite.
