GSTM1 genetic polymorphism and bladder cancer susceptibility / 中华泌尿外科杂志

Objective To study the correlation between GSTM1 genetic polymorphism and bladder cancer susceptibility. Methods In a case control study, the GSTM1 genotype was assessed by a PCR based method. 69 patients with transitional cell carcinoma of the bladder and 88 controls matched for age and sex were studied. Results The frequency of GSTM1 null genotype among the bladder cancer patients was 58% compared with 41% among controls(OR=2.0, 95%CI=1.05～ 3.79 ,? 2=4.51, P
