In a previous meta-analysis that included four Asian studies [63], it was observed that the OS of EZH2-negative patients was shorter than that of patients with positive expression for gastric cancer (HR = 0.54, 95% CI: 0.05–1.03), which was similar to our finding (HR = 0.88, 95% CI: 0.23–3.34). This evidence concerns the gene EZH2 and gastric cancer.
