Table 4 shows that the high expression of ERCC1 and ERCC2 mRNA signifies a better OS for HER2-positive GC patients, but high expression of ERCC3 mRNA was associated with poor OS for HER2-positive GC patients; similar results were also observed with ERCC4, ERCC5, and ERCC8. The gene discussed is ERCC3; the disease is gastric cancer.
