Significantly increased OS was observed for the NSCLC metastasis-positive patients with low AXL expression (AXLLow) (P = 0.014), low GAS6 (GAS6Low) (P = 0.012), N 0/1 (P = 0.032) (Fig. 2a–c), but not with other clinicopathological parameters (Figure S2, a–h). The gene discussed is GAS6; the disease is non-small cell lung carcinoma.
