Long noncoding RNA LINC00152 as a novel predictor of lymph node metastasis and survival in human cancer: a systematic review and meta-analysis
Abstract
BACKGROUND: LINC00152, a novel long noncoding RNA (lncRNA), was identified as an oncogene involved various cancers. This study was designed to explore the clinical significance and prognosis role of LINC00152.
METHODS: Eligible studies were recruited by a systematic search in PubMed, Web of Science, and Embase up to August 23, 2017. Odds ratios (ORs), hazard ratios (HRs) and 95% confidence interval (95% CI) were pooled using Review Manager 5.3 and STATA 12.0.
RESULT: A total of 10 studies with 913 patients were included to evaluate the association between LINC00152 expression and clinicopathological factors, overall survival (OS) and disease-free survivals (DFS). The results indicated that the expression level of LINC00152 was positively correlated with tumor size (OR = 5.19, 95% CI: 2.33-11.52, p < .0001), TNM stage (OR = 3.12, 95% CI: 1.77-5.51, p < .0001) and lymph node metastasis (OR = 3.41, 95% CI: 2.13-5.48, p < .00001). Moreover, elevated LINC00152 could predict unfavorable OS with pooled HR of 1.66 (95% CI: 1.29-2.13, p < .0001) and poor DFS (HR = 2.13, 95% CI: 1.39-3.25, p = .0005) in cancer patients.
CONCLUSION: LINC00152 was correlated with advanced clinicopathological features and poor prognosis as a novel predictive biomarker in various cancers.
