Abstract
Introduction:
Renal cancer is a complex and multifactorial oncourologic disease.
Objective:
To conduct a meta-analysis in order to investigate the association of GSTM1 and GSTT1 genes null polymorphisms in renal cancer.
Method:
Case-control studies in humans, published from 1999 to 2013, that investigated the association of GSTM1 and GSTT1 genes null polymorphisms in renal cancer were grouped in order to make of this meta-analysis.
Results:
Ten articles were selected on the subject proposed. No associations were found between polymorphisms of GSTM1-null (OR = 1.015, 95% CI = 0.897 to 1.147) and GSTT1-null (OR = 1.081, 95% CI = 0.791 to 1.479) and renal cancer.
Conclusions:
Based on the results obtained, we conclude that the GSTM1 and GSTT1 null polymorphisms are not associated with the risk of developing renal cancer, since they have limited role, if there is any on effective contribution in the development of renal tumors.
