Tumor CCT6A high expression was associated with LYN metastasis (P = 0.001), elevated TNM stage (P = 0.002), and abnormal CEA (P = 0.022) (Table 2), while no correlation of tumor CCT6A expression with age (P = 0.239), gender (P = 0.458), history of smoke (P = 0.107), history of drink (P = 0.565), hypertension (P = 0.774), hyperlipidemia (P = 0.824), diabetes (P = 0.479), differentiation (P = 0.627), or tumor size (P = 0.106) was observed in NSCLC patients. Here, CEACAM5 is linked to diabetes mellitus.
