EGFR and neoplasm: The univariate analysis using the Cox proportional hazards regression model indicated that the prognoses of male patients (p = 0.011), patients without vascular tumour thrombus (p = 0.007), patients without nerve invasion (P = 0.022), patients with EGFR mutation (p = 0.005), tumor size ≤ 3 cm(p = 0.003), and patients with SKN2 (p < 0.001) were relatively good.
