However, linc-ROR expression level was not correlated with age (P = 0.324), gender (P = 0.748), tumor size (P = 0.767), lymph node metastasis (P = 0.807), invasion (P = 0.675), distant metastasis (P = 0.811), TNM stage (P = 0.291), CEA (P = 0.392), and CA19-9 (P = 0.509) (Table 1). Here, CEACAM5 is linked to neoplasm.
