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.
