The expression levels of the lncRNAs CCAT1 and CCAT2 were found to be significantly increased in CRC, and both lncRNAs were significantly correlated with poor relapse-free survival (RFS) and OS; these lncRNAs could thus be used independently or jointly as important prognostic biomarkers in CRC [32]. This evidence concerns the gene CCAT2 and colorectal carcinoma.
