It has been found that the expression levels of lncRNA GASL1 (growth arrest associated lncRNA 1), PTCSC3 (papillary thyroid carcinoma susceptibility candidate 3), and MALAT1 are significantly correlated with tumor size, TNM (tumor, node, metastasis) stage, and distant metastasis of gastric cancer, respectively [68, 79, 80]. Here, MALAT1 is linked to neoplasm.
