ALB and esophageal squamous cell carcinoma: To maximize convenience for clinical utility, we focused on albumin-derived neutrophil-to-lymphocyte ratio (Alb-dNLR) score (15), which only requires albumin level, neutrophil, and leukocyte count and has been investigated to be an independent prognostic factor for esophageal squamous cell cancer (ESCC) (16) and rectal cancer (17).
