Patients with EGFR-positive NSCLC, compared with those with wildtype EGFR NSCLC, were more likely to be women (251 women [64.5%] vs 106 women [31.7%]) and never smokers (317 never smokers [81.5%] vs 121 never smokers [36.2%]) (Table 1). This evidence concerns the gene EGFR and non-small cell lung carcinoma.
