Purpose: The association between myeloperoxidase (MPO) polymorphism and the risk of cervical cancer is inconclusive. We performed a meta-analysis to clarify if a correlation exists between MPO polymorphism and the risk for developing cervical cancer. Methods: All case-control research studies that determined a relationship between MPO and cervical cancer reported up until March 1, 2018 in PubMed, Web of Science, VIP, WanFang, and the CNKI Database were accessed and included. The strength of association was evaluated with pooled odds ratios (Oils) and their corresponding 95% confidence intervals (95% CIs). We used sensitivity analysis to detect the stability of our results, conducted Q-test to evaluate heterogeneity and applied Begg's funnel plot and Egger's test to investigate any publication bias among selected studies. Results: In this meta-analysis, we included 5 eligible studies in the final evaluation, which included 1125 patients with cervical cancer and 1150 cancer-free control patients. A potential association between the MPO -463 G > A polymorphism and cervical cancer risk was observed (recessive model: OR = 0.65, 95%, CI: 0.43-0.98, P = 0.038; homozygous model: OR = 0.65, 95%, CI: 0.43-0.99, P = 0.045), which indicates that genotype AA reduces the risk of cervical cancer by 35% compared to GG/GA or GG genotypes in our results. A stratified analysis by ethnicity identified a significant correlation among Caucasian patients (recessive model: OR = 0.57, 95%, CI: 0.34-0.95, P = 0.029; homozygous model: OR = 0.60, 95%, CI: 0.36-0.99, P = 0.048) and a stratified analysis by source of control identified a significant correlation among population-based studies. Conclusions: Our results suggest that the presence of polymorphism, -463 G > A in patients might offer them protection against cervical cancer. By implementing randomized case-control or cohort studies with larger sample sizes, the clinical significance of our results can be further strengthened and verified.
