<b>Results:</b> Our meta-analysis of 14 studies comprising a total of 960 cancer patients revealed that LINC00662 overexpression was correlated with poor overall survival (HR = 1.91, 95% CI 1.49-2.45, <i>p</i> < 0.001) in cancer patients and relapse-free survival (HR = 2.12, 95% CI 1.19-3.76, <i>p</i> = 0.010) in hepatocellular carcinoma patients. The gene discussed is LINC00662; the disease is cancer.
