Abstract
Whether glutathione S-transferases (GST) polymorphisms influence the risk odds of hematological malignancy remains controversial. Therefore, we performed this meta-analysis to better analyze correlations between GST polymorphisms and hematological malignancy. Literature retrieve was conducted in PubMed, MEDLINE, and Embase. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. Sixty-two studies were enrolled for analyses. Significant associations with hematological malignancy were observed for GSTM1 (P < 0.0001, OR = 1.25, 95% CI, 1.14-1.38), GSTP1 (P = 0.002, OR = 1.20, 95% CI, 1.07-1.34), and GSTT1 (P < 0.0001, OR = 1.57, 95% CI, 1.39-1.76) polymorphisms in overall analyses. Further subgroup analyses by ethnicity revealed that GSTM1 and GSTT1 polymorphisms were both significantly correlated with hematological malignancy in Caucasians, East Asians, and West Asians, whereas GSTP1 polymorphism was only significantly correlated with hematological malignancy in Caucasians and West Asians. When we stratified data according to type of disease, positive results were found for all investigated polymorphisms in patients with certain types of acute leukemia. Moreover, GSTP1 polymorphism was also found to be significantly associated with chronic leukemia and lymphoma. Our findings indicated that GSTM1, GSTT1, and GSTP1 polymorphisms may serve as potential genetic biomarkers of hematological malignancy in certain ethnicities.
