The prognostic value of long intergenic non-protein coding RNA 460 (LINC00460) overexpression in human solid malignant tumours remains unclear. Therefore, we conducted the meta-analysis to systematically review and assess the evidence for the correlation between LINC00460 overexpression and clinicopathological features and overall survival (OS) of patients with solid malignant tumour. An electronic search of PubMed, EMBASE, Web of Science, CNKI, Cochrane Library, Chinese Biological Medical Literature database and WanFang database was applied to select eligible articles. Pooled ORs or HRs with their 95% CIs were calculated to estimate the effects. 9 eligible studies with a total of 935 patients were enrolled in this meta-analysis. The results revealed that high LINC00460 expression was associated with positive lymph node metastasis (positive vs negative: OR=2.97, 95% CI 1.74 to 5.05, p=0.812), advanced tumour-node-metastasis stage (III+IV vs I+II: OR=2.82, 95% CI 1.64 to 4.85, p=0.193) and poorer differentiation (high vs low: OR=0.60, 95% CI 0.36 to 0.99, p=0.569). Additionally, the overexpression of LINC00460 could predict a poorer OS (HR=1.57, 95% CI 1.39 to 1.77) and the shorter disease-free survival (HR=2.32, 95% CI 1.25 to 4.31). Furthermore, according to subgroup analysis and meta-regression results, the heterogeneity of current meta-analysis may be attributed to the differences of cancer type and follow-up months. High expression of LINC00460 could predict poor prognosis in patients with solid malignant tumour. LINC00460 may serve as potential prognostic biomarker for clinical outcomes in various human solid malignant tumours.
