ERCC8 and gastric cancer: The high expression of ERCC8 mRNA indicated a worse OS for all GC patients (HR=1.34, 95% CI=1.02–1.76, P=0.034, Figure 10(a)) and for those with diffuse-type GC (HR=2.25, 95% CI=1.36–3.75, P=0.0013, Figure 10(c)), but there was no significant correlation with better or worse OS for the patients with intestinal and mixed-type GC (Figures 10(b) and 10(d)).
