The research on lncRNA surged after the 2003 discovery of MALAT1’s involvement in the metastasis of non-small cell lung cancer (NSCLC).21 Similar to miRNAs, lncRNAs’ role in cancer is now well studied but only rarely translated into clinical practice, the exception being PCA3 as a biomarker for prostate cancer.22 Here, PCA3 is linked to non-small cell lung carcinoma.
