Abstract
The Role of GSTM1 and GSTT1 Polymorphism in Patients with Renal Cell CarcinomaMembers of the glutathione S-transferase (GST) superfamily exhibit polymorphic expression. GSTs are investigated as biomarkers of risk for various cancers, including renal cell carcinoma (RCC). The aim of this study was to test the association betweenGSTM1andGSTT1polymorphism and susceptibility to RCC, independently or in conjunction with known risk factors. Genomic DNA was isolated from 182 controls and 76 patients with RCC.GSTM1andGSTT1genotypes were determined by multiplex PCR. Data obtained were analyzed with respect to RCC risk factors including smoking and occupational exposure. The frequency ofGSTM1-null genotype was higher in patients with RCC (60.5%) compared to controls (47.2%).GSTT1-null genotype was found in 28.6% controls and 27.6% of cases.GSTM1-null individuals exhibit 1.9-fold increased risk of RCC (95% CI: 1.06-3.33). The presence ofGSTT1active genotype was associated with increased risk of RCC in occupationally exposed subjects when unexposedGSTT1-null subjects were used as a comparison group (OR: 2.48; 95% CI: 1.05-5.86). No association was found between the inactive form ofGSTM1andGSTT1and smoking in RCC patients. In a Serbian cohort of patients, the presence of aGSTM1active genotype is protective against RCC, whereas aGSTT1active genotype increases RCC risk in occupationally exposed subjects.
