For non-small cell lung cancer (NSCLC), variant genotypes of ABCG2 rs3114020 were found to be associated with a significantly increased risk of death (p < 0.001), and the rs1871744 genotype was significantly associated with poor response, suggesting that ABCG2 mutation patterns can be an independent risk factor for the prognosis of NSCLC [13]. The gene discussed is ABCG2; the disease is non-small cell lung carcinoma.
