Occupational exposure constitutes a common risk factor for lung cancer. We observed molecular alterations in 73% of never-smokers, 35% of men and 8% of women were exposed to at least one occupational carcinogen. We report herein associations between molecular patterns and occupational exposure. BioCAST was a cohort study of lung cancer in never-smokers that reported risk factor exposure and molecular patterns. Occupational exposure was assessed via a validated 71-item questionnaire. Patients were categorised into groups that were unexposed and exposed to polycyclic aromatic hydrocarbons (PAH), asbestos, silica, diesel exhaust fumes (DEF), chrome and paints. Test results were recorded for EGFR, KRAS, HER2, BRAF and PIK3 mutations, and ALK alterations. Overall, 313 out of 384 patients included in BioCAST were analysed. Asbestos-exposed patients displayed a significantly lower rate of EGFR mutations (20% versus 44%, p=0.033), and a higher rate of HER2 mutations (18% versus 4%, p=0.084). ALK alterations were not associated with any occupational carcinogens. The DEF-exposed patients were diagnosed with a BRAF mutation in 25% of all cases. Chrome-exposed patients exhibited enhanced HER2 and PIK3 mutation frequency. Given its minimal effects in the subgroups, we conclude that occupational exposure slightly affects the molecular pattern of lung cancers in never-smokers. In particular, asbestos-exposed patients have a lower chance of EGFR mutations. Asbestos exposure is associated with a lower rate of EGFR mutation in lung cancer of never-smokers http://ow.ly/wFUY30fkbcz

不吸烟者肺癌体细胞突变与职业暴露的关系

职业暴露是肺癌的常见危险因素。我们观察到 73% 的从不吸烟者、35% 的男性和 8% 的女性暴露于至少一种职业致癌物的分子改变。我们在此报告分子模式与职业暴露之间的关联。BioCAST 是一项针对不吸烟者肺癌的队列研究,报告了风险因素暴露和分子模式。职业暴露通过经过验证的 71 项问卷进行评估。患者被分为未接触和接触多环芳烃 (PAH)、石棉、二氧化硅、柴油机尾气 (DEF)、铬和油漆的组。记录了 EGFR、KRAS、HER2、BRAF 和 PIK3 突变以及 ALK 改变的测试结果。总体而言,分析了 BioCAST 中 384 名患者中的 313 名。石棉暴露患者的 EGFR 突变率显着降低(20% 对 44%,p=0.033),而 HER2 突变率更高(18% 对 4%,p=0.084)。ALK 改变与任何职业致癌物无关。25% 的暴露于 DEF 的患者被诊断为 BRAF 突变。接触铬的患者表现出增强的 HER2 和 PIK3 突变频率。鉴于其在亚组中的影响很小,我们得出结论,职业暴露对从不吸烟者肺癌的分子模式有轻微影响。特别是,接触石棉的患者发生 EGFR 突变的机会较低。石棉暴露与从不吸烟者肺癌中较低的 EGFR 突变率有关 http://ow.ly/wFUY30fkbcz 和更高的 HER2 突变率(18% 对 4%,p=0.084)。ALK 改变与任何职业致癌物无关。25% 的暴露于 DEF 的患者被诊断为 BRAF 突变。接触铬的患者表现出增强的 HER2 和 PIK3 突变频率。鉴于其在亚组中的影响很小,我们得出结论,职业暴露对从不吸烟者肺癌的分子模式有轻微影响。特别是,接触石棉的患者发生 EGFR 突变的机会较低。石棉暴露与从不吸烟的肺癌患者中较低的 EGFR 突变率有关 http://ow.ly/wFUY30fkbcz 和更高的 HER2 突变率(18% 对 4%,p=0.084)。ALK 改变与任何职业致癌物无关。25% 的暴露于 DEF 的患者被诊断为 BRAF 突变。接触铬的患者表现出增强的 HER2 和 PIK3 突变频率。鉴于其在亚组中的影响很小,我们得出结论,职业暴露对从不吸烟者肺癌的分子模式有轻微影响。特别是,接触石棉的患者发生 EGFR 突变的机会较低。石棉暴露与从不吸烟的肺癌患者中较低的 EGFR 突变率有关 http://ow.ly/wFUY30fkbcz 接触铬的患者表现出增强的 HER2 和 PIK3 突变频率。鉴于其在亚组中的影响很小,我们得出结论,职业暴露对从不吸烟者肺癌的分子模式有轻微影响。特别是,接触石棉的患者发生 EGFR 突变的机会较低。石棉暴露与从不吸烟的肺癌患者中较低的 EGFR 突变率有关 http://ow.ly/wFUY30fkbcz 接触铬的患者表现出增强的 HER2 和 PIK3 突变频率。鉴于其在亚组中的影响很小,我们得出结论,职业暴露对从不吸烟者肺癌的分子模式有轻微影响。特别是,接触石棉的患者发生 EGFR 突变的机会较低。石棉暴露与从不吸烟的肺癌患者中较低的 EGFR 突变率有关 http://ow.ly/wFUY30fkbcz
