Prognostic value of lncRNA ROR expression in various cancers: a meta-analysis

Abstract
Background: There is a dispute on the prognostic value of long non-coding RNA regulator of reprogramming (lncRNA ROR) in cancers. The purpose of this study was to evaluate the prognostic significance of lncRNA ROR expression in human cancers. Methods: PubMed, Embase and Cochrane Library were searched to look for relevant studies. The meta-analyses of prognostic and clinicopathological parameters were conducted. Results: A total of 10 studies were finally included into the meta-analysis. High lncRNA ROR expression was significantly associated with shorter overall survival (OS) (HR=2.88, 95%CI=2.16-3.84, P Conclusion: High lncRNA ROR expression was associated with worse prognosis in cancers. LncRNA ROR expression could serve as an unfavorable prognostic factor in various cancers.
