For clinicopathological factors, older age (p = 0.001), male patients (p < 0.001), smoker (p = 0.002), sublobar resections (p = 0.002), Tumor grade (p = 0.012), “T” (p = 0.005), “N” (p < 0.001), “M” (p = 0.006), and GPX4 (p = 0.017 and 0.002, at 5% and 25% cutoff, respectively) were associated with poor OS in univariate analysis. The gene discussed is GPX4; the disease is neoplasm.
