Significantly, ALRI levels demonstrated correlation with tumor location (p = 0.0001), pathological type (p = 0.0028), lymph invasion (p = 0.0167), venous invasion (p = 0.0167), depth of tumor invasion (p < 0.0001), CEA level (p = 0.0063), and CA19-9 level (p = 0.0035). Here, CEACAM5 is linked to neoplasm.
