ALB and neoplasm: In the Cox proportional regression analysis, ECOG PS score ≥ 2 (HR, 2.14; 95% CI: 1.16–3.96; p = 0.02), 100 ≤ Eo <500 (HR, 0.39; 95% CI: 0.16–0.94; p = 0.04), tumor size ≥5 cm (HR, 1.79; 95% CI: 1.08–2.96; p = 0.02), and PD‐L1 ≥ 1% (HR, 0.51; 95% CI: 0.31–0.85; p = 0.01) correlated with OS (Table 3), whereas stage, liver metastasis, neutrophils, lymphocytes, CRP, and Alb did not.
