Endoscope non-traversable esophageal cancer patients also demonstrated an advanced clinical stage (P < .001), a poor ECOG performance status score (P < .001), a lower serum albumin level (3.83 ± 0.69 g/dL vs 3.44 ± 0.62 g/dL, respectively, P < .001), a higher rate of requirement for esophageal stent insertion (7.5% vs 37.3%, respectively, P < .001), and definitive CRT as their initial treatment (40.9% vs 84.0%, respectively, P < .001) compared with patients in Group A. The relationship between endoscopic non-traversability and an advanced stage of esophageal cancer has been previously noted. Here, ALB is linked to esophageal cancer.
