For example, lnc-MAFG-AS1 correlates with invasive depth, tumor, node, metastasis (TNM) stage and unsatisfied disease-free survival (DFS), and OS in colorectal cancer patients (17); it is also related to diffuse type, extensive invasion depth, frequent lymph node metastasis, and distant metastasis and predicts worse OS in gastric cancer patients (26). This evidence concerns the gene MAFG and metastasis.
