ObjectiveTo systematically review the association between glutathione S-transferase pi (GSTP1) Ile105Val (A/G) and the risk of cutaneous melanoma. MethodWe searched PubMed, EMbase, CNKI and WanFang Data to identify case-control studies which investigated the association between GSPT1 Ile105Val (A/G) polymorphism and the risk of cutaneous melanoma from their inception to June 31th 2016. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then meta-analysis was performed by using RevMan 5.3 software. ResultsA total of 4 case-control studies involving 978 cutaneous melanoma cases and 796 controls were included. The results showed that: the GSPT1 Ile105Val (A/G) polymorphism was significantly associated with the risk of cutaneous melanoma in the dominant model (GG+GA vs. AA: OR=1.22, 95%CI 1.01 to 1.48, P=0.04), but no significant association was found in the recessive model, heterozygote model, and homozygote model (GG vs. CA+AA: OR=1.18, 95%CI 0.86 to 1.60, P=0.30; GA vs. AA: OR=1.20, 95%CI 0.98 to 1.47, P=0.08; GG vs. AA: OR=1.28, 95%CI 0.92 to 1.77, P=0.14). ConclusionCurrent evidence shows, The GSTP1 Ile105Val (A/G) polymorphism is associated with the risk of cutaneous melanoma. Due to limited quantity and quality of the included studies, more high-quality large-scale studies are needed to verify the above conclusion.
