CCAT2 and neoplasm: As shown in Table 1, high CCAT2 level was not associated with patient age (P = 0.702), histological subtype (P = 0.918) or tumor size (P = 0.336); however it was significantly positively correlated with FIGO stage (P = 0.002), tumor grade (P = 0.006) and distant metastasis (P < 0.001).
