There were some studies on the associations between Glutathione S-transferase M1 (GSTM1) and Glutathione S-transferase T1 (GSTT1) polymorphisms and cervical cancer (CC) risk, but the results were inconsistent.Thus, a meta-analysis was performed.
Previous studies have suggested that glutathione S-transferase (GST) genotypes may play a role in determining susceptibility to cervical cancer, though the data have often been conflicting.
The authors established the genotype frequencies of cytochrome P450 (CYP1A1/MspI, CYP2E1/PstI, and CYP2E1/DraI), glutathione-S-transferase (GSTM1 and GSTT1), and p53 (exon 4/AcclI and intron 3/16-base pair duplication) gene polymorphisms in cervical carcinoma patients and controls and evaluated the association between the specific genotype or genotype combinations of these polymorphisms and the risk of cervical carcinoma.
