The clinicopathological and prognostic value of long non-coding RNA ZEB1-AS1 in solid tumors: A meta-analysis
Abstract
BACKGROUND AND AIM
Studies have reported that Zinc finger E-box binding homeobox 1 antisense 1 (ZEB1-AS1) is overexpressed in many malignant tumors. However, the sample size in those studies was limited, so the clinicopathological and prognostic value of ZEB1-AS1 in solid tumors remains undetermined, Accordingly, the aim of this meta-analysis was to evaluate the relationship between the expression of lncRNA ZEB1-AS1 and clinicopathological characteristics and prognosis in patients with solid tumors.
METHODS
Pooled odds ratios (ORs) and hazard ratios (HRs) were estimated with 95% confidence interval (CI) to assess the relation between ZEB1-AS1 and the clinicopathological characteristics and prognosis of patients with cancer.
RESULTS
A total of 10 studies, comprising 861 patients, were included in this meta-analysis. The pooled results suggested that high ZEB1-AS1 expression was related to low differentiation (low vs. high + moderate: OR = 2.99, 95% CI = [2.03, 4.39]), increased lymph node metastasis (YES vs. NO: OR = 4.62, 95% CI = [2.90, 7.37]) and advanced TNM stage (I + II vs. III + IV: OR = 0.41, 95% CI = [0.23, 0.75]), but not to gender and tumor size. Moreover, high ZEB1-AS1 expression was associated with poor overall survival (OS; HR = 1.86, 95% CI = [1.57, 2.14]) and disease-free survival (DFS; HR = 2.03, 95% CI = [1.28, 2.77]). Thus, ZEB1-AS1 could be an independent predictive factor for OS (HR = 2.07, 95% CI = [1.57, 2.56]) in patients with cancers.
