Identification of genomic instability-related lncRNA signature based on the “train” set. (a) Univariate analysis of five-genomic instability-related lncRNA (GI-lncRNA) signature in the “train” set; (b) ROC curve analysis of the five-GI-lncRNA signature in the “train” set; (c) the expression of the five-GI-lncRNA signature by increasing risk score in the “train” set, the median value of the risk score is taken as the cutoff, and samples are divided into the “high-risk” and “low-risk” groups; (d) Kaplan-Meier curve analysis of survival between the “high-risk” group and the “low-risk” group in the “train” set; (e) somatic mutation count by increasing risk score in the “train” set.
