CEACAM5 and neoplasm: Univariate Cox’s regression disclosed that tumor CCT6A high expression (P < 0.001, HR 1.952 (95%CI 1.515–2.516)) was correlated with unfavorable OS, and poor differentiation (P = 0.001, HR 1.368 ((95%CI 1.133–1.652)), tumor size (>5.0 cm) (P < 0.001, HR 1.605 (95%CI 1.248–2.064)), LYN metastasis (P < 0.001, HR 3.081 (95%CI 2.385–3.979)), higher TNM stage (P < 0.001, HR 1.446 (95%CI 1.244–1.682)) as well as abnormal CEA (>5.0 ng/mL) (P < 0.001, HR 1.880 (95%CI 1.444–2.447)) were also correlated with worse OS (Table 4).
