Note. Cutoff value: the critical value to distinguish between high and low lncRNA expression; OS : overall survival; mean ratio: average expression level of lncRNA; median value: median expression level of LncRNA; — : no mention in text; OS : overall survival; DFS : disease-free survival; RFS : relapse-free survival; both: reported in text and survival curve; SDD : surgery to the date of death.
