CEACAM5 and gastric cancer: Multivariate logistic regression analysis showed that younger age (OR: 0.68, 95% CI: 0.547–0.844, P < 0.001), higher NLR (OR: 2.858, 95% CI: 2.295–3.559, P < 0.001), higher CEA (OR: 2.108, 95% CI: 1.671–2.661, P < 0.001), higher CA199 (OR: 1.844, 95% CI: 1.466–2.32, P < 0.001) and higher CA724 (OR: 2.348, 95% CI: 1.851–2.978, P < 0.001) were independent risk factors for GC metastasis (Table 4).
