摘要
We performed a comprehensive meta-analysis to determine the association between XPD/ERCC2 Lys751Gln polymorphism and melanoma susceptibility. Based on comprehensive searches of the MEDLINE, EMBASE and ISI Web of knowledge, China National Knowledge Infrastructure (CNKI) and Wanfang Database, we identified eligible studies about the association between XPD/ERCC2 Lys751Gln polymorphism and melanoma risk. A total of 5,961 cases and 8,669 controls in studies were included in this meta-analysis. All studies were conducted in Caucasian populations. Allele model (Lys vs. Gln: P = 0.53; OR = 0.98, 95% CI = 0.91-1.05), and homozygous model (Lys/ Lys vs. Gln/Gln: P = 0.32; OR = 0.93, 95% CI = 0.81 to 1.07) did not show increased risk of developing melanoma. Similarly, dominant model (Lys/Lys+Lys/Gln vs. Gln/Gln: P = 0.18; OR = 0.93, 95% CI = 0.83 to 1.03) and recessive model (Lys/Lys vs. Lys/Gln+Gln/Gln: P = 0.73; OR = 0.98, 95% CI = 0.88 to 1.09) failed to show increased risk of developing melanoma. Our pooled data suggest that there was no evidence for a major role of XPD/ERCC2 Lys751Gln polymorphism in the pathogenesis of melanoma among Caucasian populations.
