EGFR and non-small cell lung carcinoma: Recently, Li et al. [23] reported that patients with higher microRNA-200c expression achieved longer PFS (5.0 versus 1.2 months; HR, 0.38; 95% CI, 0.21–0.70, P = 0.002) and OS (9.6 versus 5.0 months; HR, 0.54; 95% CI, 0.30–0.96, P = 0.035) than those with lower microRNA-200c expression in patients with wild-type EGFR NSCLC.
