Background: The association between Aurora-A V57I (rs1047972, G>A) polymorphism and cancer susceptibility has been widely studied. However, the results are inconsistent.
Methodology/principal Findings: To obtain a more precise evaluation of the relationship, we performed a meta-analysis of 14 case-control studies involving a total of 11,245 cancer cases and 16,024 controls. Our results demonstrated that there was a borderline evidence of an association between the Aurora-A V57I polymorphism and the decreased risk of overall cancer in two genetic models: AA vs. GA+GG and AA vs. GG. In a stratified analysis by cancer type, significant association between Aurora-A V57I polymorphism and the decreased risk of breast cancer was identified in one genetic model: AA vs. GG. In a stratified analysis by ethnicity, in three genetic models, significant decreased cancer risk was observed among Caucasians (AA vs. GA+GG; AA vs. GG and A vs. G) instead of Asians. Furthermore, a stratified analysis by ethnicity in breast cancer subgroup, five genetic models (AA+GA vs. GG; AA vs. GA+GG; AA vs. GG; AA vs. GA and A vs. G), significant decreased cancer risk was observed among Caucasians, but not among Asians. A slight publication bias was observed in our meta-analysis, thus nonparametric "trim-and-fill" method was utilized to detect the stability of our results. The adjusted odds ratios and confidence intervals showed that Aurora-A V57I polymorphism might be a protective factor for cancer risk, suggesting the reliability of our findings.
Conclusion: In summary, this meta-analysis suggests that Aurora-A V57I polymorphism may be a protective factor for cancer risk.

: It is still conflicting for the correlation between cancer susceptibility and Aurora-A V57I (rs1047972) gene variant from the published researches. This meta-analysis was performed to access the correlation between cancer susceptibility and Aurora-A rs1047972 gene polymorphism by using meta-analysis methods. : Eligible studies published before Nov 1, 2019 were systematically searched in PMC, PubMed, EMBASE, Web of Science, Cochrane Library Database, China National Knowledge Infrastructure, Wanfang databases, in order to collect qualified case-control or cohort studies.

Lung cancer, a complex neoplasm of lung tissue, is influenced by several environmental and genetic factors which could be changed in each individual. Aurora-A gene is related to mitotic events such as: chromosome instability, cell cycle regulation, spindle formation, and kinetechore-microtubule connections. This centrosomic serine/threonine kinase provides a strong connection between mitotic errors and carcinogenesis.

Aurora-A kinase is considered a potential cancer susceptibility gene that encodes a centrosome-associated, cell cycle-regulated serine/threonine kinase. We studied two single nucleotide polymorphisms (SNP) in the coding region of Aurora-A, 91T-to-A (F31I) and 169G-to-A (V57I). We studied the influence of these two polymorphisms on age of onset of hereditary nonpolyposis colorectal cancer (HNPCC).
