CEACAM5 and neoplasm: Then, logistic regression analysis was performed and it revealed that FCRLB expression level was significantly correlated with CEA level (OR = 2.373 (1.574–3.610), p < 0.001), T stage (OR = 1.992 (1.346–2.975), p < 0.001), N stage (OR = 1.743 (1.271–2.396), p < 0.001, M stage (OR = 2.010 (1.263–3.253), p = 0.004), AJCC stage (OR = 1.636 (1.190–2.253), p = 0.002), residual tumor (OR = 2.174 (1.125–4.423), p = 0.025), perineural invasion (OR = 1.865 (1.033–3.418), p = 0.040), and lymphatic invasion (OR = 1.480 (1.061–2.070), p = 0.021) (Table 1).
