[21] showed that the chemotherapeutic responses of the ovarian cancer patients with genotype TT at ERCC1 rs11615 locus were better than those with genotype TC + CC, while Kang et al. [22] believed that ovarian cancer patients with genotype CT + TT were more sensitive to platinum chemotherapy than those with genotype CC.
