Overexpression of lncRNA-ZEB1-AS1 was signifcantly associated with histological grade (P = 0.002), lymphatic metastasis (P = 0.001) and distant metastasis (P = 0.035), but not with patients’ age (P = 0.082), gender (P = 0.521), tumor size (P = 0.054),TNM stage (P = 0.313) and vascular infltration P = 0.169). The p-value represents the comparison between groups (*p < 0.05, **p < 0.01).
