Up‐regulation of lncRNA DLEU2 expression was associated with poor survival in patients with NSCLC. A, FISH analysis of the localization and expression levels of lncRNA DLEU2 in LAC tissues. B, qRT‐PCR analysis of the expression levels of lncRNA DLEU2 in LAC tissue samples. C, TCGA analysis of the expression levels of lncRNA DLEU2 in paired and unpaired LAC tissues. D, ROC curve analysis of the cut‐off value, AUC, sensitivity and specificity of lncRNA DLEU2 in LAC patients. E, The cut‐off value divided the LAC patients into high DLEU2 expression and low DLEU2 expression groups. F, Kaplan‐Meier analysis of the association of high or low lncRNA DLEU2 expression with the poor survival and tumour recurrence in LAC patients
