Our results in the univariate analysis revealed that high expression of AXL (AXLHigh) (HR 2.19, 95% CI 1.33–4.10, P = 0.005), and GAS6 (GAS6High) (HR 2.04, 95% CI 1.01–3.71, P = 0.019), and N stage (HR 2.08, 95% CI 1.24–3.82, P = 0.01) were predictors for poor OS in patients with NSCLC with BM (Table 6). The gene discussed is GAS6; the disease is non-small cell lung carcinoma.
