CEACAM5 and neoplasm: Multivariate analysis revealed that ASA-PS (HR: 3.366, 95.0% CI: 1.917 - 5.911; p < 0.001), tumor differentiation (HR: 1.705, 95.0% CI: 1.087–2.674; p = 0.020), pTNM stage (HR: 2.160, 95.0% CI: 1.218–3.758; p = 0.008), and CEA (HR: 1.964, 95.0% CI: 1.251–3.083; p = 0.003) were the independent prognostic factors for OS (Table 2).
