EGFR and non-small cell lung carcinoma: Interestingly, we also found that high expression levels of these four major genes were correlated with the poor OS of NSCLC patients: EGFR (HR: 1.2999; 95% CI: 1.0094–1.674; P value: 0.4214); IL-6 (HR: 1.6692; 95% CI: 1.23432–2.258; P value <0.001); JUN (HR: 1.4714; 95% CI: 1.1165–1.9390; P value: 0.00609); MYC (HR: 1.6546; 95% CI: 1.2511–2.1882; P value <0.001) (Figures 7(a), 7(b), 8(a), and 8(b)).
