ALB and squamous cell carcinoma: In the univariate analysis of the Cox regression model, ALB <35 g/L, dNLR >3 and metastatic sites number ≥2 were risk factors for PFS (HR 1.54, 95% CI 1.49–4.34; P=0.001; HR 1.92, 95% CI 1.17–3.15; P=0.010; HR 1.76, 95% CI 1.11–2.78; P=0.016), while ALB <35 g/L, dNLR >3, metastatic sites number ≥2 and squamous cell carcinoma were risk factors for OS (HR 4.48, 95% CI 2.12–9.47; P < 0.001; HR 2.16, 95% CI 1.02–4.54; P=0.044; HR 2.23, 95% CI 1.11–4.75; P=0.024; HR 2.70, 95% CI 1.32–5.52; P=0.006).
