The median Alb value (25%–75%) was 2.7 (2.2–2.8) g/dL in the patients with hepato-biliary-pancreas cancer and 2.5 (2.3–2.9) g/dL in the patients with gastrointestinal tract cancer, with a significant difference being observed in the lower range for gastrointestinal cancer cases (p=0.049). This evidence concerns the gene ALB and digestive system cancer.
