However, Xue et al. found that the ERCC2 rs13181 and rs1799793 polymorphisms are not correlated with response to FOLFOX chemotherapy but revealed a significantly increased risk of death from gastric cancer among patients with the ERCC2 rs1799793 AA genotype compared with patients with the GG genotype in terms of overall survival [18]. Here, ERCC2 is linked to gastric cancer.
