We next evaluated the diagnostic role of ERCC6 mRNA expression (Affymetrix ID: 207347_at); high ERCC6 mRNA expression was associated with worse OS for all GC patients (HR=1.25, 95% CI=1.02–1.54, P=0.029, Figure 9(a)) and for those with intestinal-type GC (HR=1.62, 95% CI=1.04–2.54, P=0.033, Figure 9(b)), but there was no significant correlation with better or worse OS for patients with diffuse and mixed-type GC (Figures 9(c) and 9(d)). The gene discussed is ERCC6; the disease is gastric cancer.
