Moreover, UCA1 functions as a competing endogenous RNA to suppress epithelial ovarian cancer metastasis [15].UCA1, significantly associated with LNM and OS, may function as on oncogene and a potential indicator of prognosis in some cancers, including colorectal cancer, esophageal squamous cell carcinoma, prostate cancer, hepatocellular carcinoma and ovarian cancer [5–16]. This evidence concerns the gene UCA1 and esophageal squamous cell carcinoma.
