The results of HR showed as high NEAT1 expression versus low NEAT1 expression for DFS in patients with colorectal cancer was 1.80 (95% CI = 1.27–2.55, P < 0.001), and for PFS in patient with ovarian cancer was 2.99 (95% CI = 1.21–4.36, P = 0.011), which indicated a significantly positive association between high expression level of NEAT1 and poor DFS or poor PFS. This evidence concerns the gene NEAT1 and ovarian cancer.
