Abstract

OBJECTIVES: In view of the controversies surrounding the association of glutathione S-transferases (GST) P1 with endometriosis, a meta-analysis of GSTP1 -313A/G polymorphism with endometriosis risk was performed. STUDY DESIGN: The relevant studies were identified through a search of PubMed, Excerpta Medica Database (Embase), Elsevier Science Direct and Chinese Biomedical Literature Database (CBM) until March 2013. The association between GSTP1 -313A/G polymorphism and endometriosis risk was pooled by odds ratios (ORs) together with their 95% confidence intervals (95% CIs). RESULTS: A total of eight case-control studies were eventually identified. We found that GSTP1-313A/G polymorphism was not associated with endometriosis risk in the overall population (A vs. G: OR=1.02, 95% CI=0.97-1.07, P=0.511; AA vs. GG: OR=1.02, 95% CI=0.98-1.06, P=0.359; GA vs. GG: OR=1.03, 95% CI=0.98-1.08, P=0.299; AA vs. GA/GG: OR=1.01, 95% CI=0.96-1.07, P=0.621; AA/GA vs. GG: OR=1.00, 95% CI=0.97-1.03, P=0.972). In the sub-group analysis based on ethnicity, a significant association was found in Caucasians under the recessive model (AA vs. GA/GG: OR=1.28, 95% CI=1.08-1.53, P=0.006). CONCLUSIONS: GSTP1 -313A/G polymorphism may not be associated with endometriosis risk, while the observed increase in risk of endometriosis may be due to small-study bias. Considering the limited sample size and ethnicity included in our meta-analysis, an updated meta-analysis will be urgently needed when further larger and well-designed studies are published.
