GSTP1 and lung cancer: When we analysed the association between the GSTP1 genotypes and lung cancer risk, we found no association between individuals with the variant genotype Val/Val or the carriers of variant allele Val (Ile/Val + Val/Val) and the risk of developing lung cancer (adjusted OR = 0.83; 95% CI = 0.57-1.19 and adjusted OR = 0.83; 95% CI = 0.66-1.05, respectively) (Table2).
