Univariate Cox’s regression showed that tumor high CCT6A was associated with decreased DFS (P < 0.001, HR 1.802 (95%CI 1.434–2.265)), meanwhile, age (>60.0 years) (P = 0.019, HR 1.314 (95%CI 1.047–1.649)), poor differentiation (P = 0.002, HR 1.306 (95%CI 1.102–1.548)), tumor size (>5.0 cm) (P = 0.008, HR 1.363 (95%CI 1.083–1.715)), LYN metastasis (P < 0.001, HR 2.383 (95%CI 1.883–3.016)), higher TNM stage (P < 0.001, HR 1.448 (95%CI 1.265–1.658)), and abnormal CEA (>5.0 ng/mL) (P = 0.002, HR 1.434 (95%CI 1.138–1.806)) were correlated with shorter DFS as well (Table 3). Here, CEACAM5 is linked to neoplasm.
