We appreciate the authors’ interest in our study “Proportion of Never-Smoker Non–Small Cell Lung Cancer Patients at Three Diverse Institutions.” It is important to note, however, that in our study, we examined the proportion of never-smokers in non–small cell lung cancer (NSCLC) patients, not the incidence of lung cancer cases in never-smokers, as was described in the correspondence. Based on our data, our conclusion is that the proportion of never-smokers is increasing among the NSCLC patient population at our three institutions. In other words, we did not conclude that the incidence of lung cancer in never-smokers is increasing, but rather that the proportion of never-smokers is increasing among the NSCLC patient population at our institutions and that this increase does not seem to be explained by differences in stage at diagnosis or by differences in referral patterns.

我们感谢作者对我们的研究“三个不同机构的不吸烟非小细胞肺癌患者的比例”的关注。重要的是要注意，但是，在我们的研究中，我们检查了非小细胞肺癌（NSCLC）患者中从未吸烟者的比例，而不是未吸烟者中肺癌病例的发生率。一致。根据我们的数据，我们的结论是，在我们的三个机构中，非吸烟者在非小细胞肺癌患者中的比例正在增加。换句话说，我们并未得出结论，从不吸烟者中肺癌的发病率正在增加，
