Abstract
BACKGROUND/AIMS: Many studies have reported that PVT1 played important roles in diverse cancer types. But the systematic analysis of PVT1 in gastrointestinal cancers has not been inspected. Thus, we aimed to investigate clinical value of the long noncoding RNA PVT1 (lncRNA) expression in digestive system cancers. METHODS: Eligible studies were collected from a number of databases (PubMed, Web of Science, Embase, Chinese National Knowledge Infrastructure and Wanfang database). Pooled hazard ratio (HR) or odds ratio (OR) with 95 % confidence interval (95 % Cl) were applied to assess the clinical significance of PVT1. RESULTS: Data from 15 articles were included with a total of 2585 patients. Elevated PVT1 expression were significantly related to poor overall survival (OS) [HR = 1.86, 95% CI (1.44, 2.28); p<0. 0001] in digestive system cancers. The same association was also observed between PVT1 expression with outcomes, including disease free survival (DFS), disease specific survival (DSS) and relapse free survival (RFS). The lncRNA PVT1 could also be predicative for some clinicopathological features. CONCLUSIONS: This meta-analysis revealed that PVT1 may serve as a prognostic predictor and pathological biomarker in digestive system cancers.
