CEACAM5 and neoplasm: Univariate Cox’s proportional hazard regression analysis of OS displayed that katanin P60-high expression (P = 0.004, HR = 1.567), higher pathological grade (P = 0.001, HR = 1.508), tumor size (> 5.0 cm) (P = 0.008, HR = 1.499), LYN metastasis (P < 0.001, HR = 3.107), higher TNM stage (P < 0.001, HR = 1.494), and abnormal CEA (P = 0.001, HR = 1.668) were correlated with poor OS (Table 4).
