Differences of normalized MALAT1 levels between cancer patients and cancer-free subjects were significant for NSCLC vs. controls (p < 0.0001), AdCa vs. controls (p = 0.0043), and SqCC vs. controls (p = 0.0001), whereas the difference between AdCa and SqCC was not significant (Figure 2). This evidence concerns the gene MALAT1 and non-small cell lung carcinoma.
