Univariate Cox’s proportional hazard regression analysis of DFS displayed that katanin P60-high expression (P = 0.001, HR = 1.607), tumor size (> 5.0 cm) (P = 0.018, HR = 1.389), LYN metastasis (P < 0.001, HR = 2.565), higher TNM stage (P < 0.001, HR = 1.524), and abnormal CEA level (P = 0.011, HR = 1.420) were correlated with poor DFS in NSCLC patients (Table 3). This evidence concerns the gene CEACAM5 and neoplasm.
