COLCA1 and metastatic malignant neoplasm in the lymph nodes: Half of this lncRNA expression was significantly correlated with lymph node metastasis (Figure 4B), and most of these lncRNA expressions in late stage (stage III‐IV) were significantly different from early (stage I‐II) (Figure 4C), and the expression levels of two lncRNA (COLCA1 and TRG‐AS1) were associated with T stage (Figure 4D).
