Abstract:
This study aims to investigate the influence of ATP7B genetic polymorphism to platinum-based chemotherapy in Chinese Han lung cancer patients. A total of 338 Chinese Han lung cancer patients were enrolled in this study. All patients underwent at least two cycles of platinum-based chemotherapy. Four tag SNPs of ATP7B (rs1061472, rs9535826, rs7999812, and rs9535828) were selected to evaluate their impacts to platinum-based chemotherapy in these patients. ATP7B rs9535828 and rs9535826 were found to be associated with platinum resistance in Chinese Han lung cancer patients. Patients with A allele in ATP7B rs9535828 presented an increased susceptibility to platinum drugs (OR 1.96, 95 % CI 1.17-3.30, p < 0.01). Patients with G allele in ATP7B rs9535826 had the highest susceptibility to platinum drugs (OR 2.05, 95 % CI 1.19-3.52, p < 0.01). Our findings suggest that ATP7B genetic polymorphisms could affect the therapeutic efficacy of platinum-based chemotherapy, and ATP7B gene might be considered as predictive markers for the efficacy evaluation of platinum-based chemotherapy in Chinese Han lung cancer patients.
