CEACAM5 and cancer: According to the univariate analysis, obstructive cancer (p = 0.045), CEA level ≥ 5.0 ng/mL (p < 0.01), CA19-9 level ≥ 37.0 ng/mL (p < 0.01), T3 or higher disease (p < 0.01), stage III CRC (p < 0.01), lymphovascular invasion (p = 0.019), and high TMI (p < 0.01) were potential risk factors for cancer-specific mortality.
