The A1298C polymorphism of the methylenetetrahydrofolate reductase (MTHFR) gene has been reported to be associated with hepatocellular carcinoma (HCC), but there are conflicting results from previous studies. The present study aimed to investigate the association between this polymorphism and the risk of HCC using a meta-analysis of the published studies. Published literature from PubMed and Embase databases was systematically searched to identify relevant studies before October 2014. The Begg test was used to measure publication bias.

X. Y. Shi and Shen, Q., MTHFR A1298C polymorphism and ovarian cancer risk: a meta-analysis, vol. 14, pp. 8211-8218, 2015.

Numerous studies have evaluated the association between the MTHFR A1298C polymorphism and ovarian cancer risk. However, the specific association is still controversial. Therefore, we performed the present meta-analysis. A systematic literature search of PubMed and Embase databases was undertaken in August 2014, and the reference lists of articles were retrieved. ORs with their 95%CI were calculated to evaluate the strength of the association. Meta-analysis was performed using the STATA version 12.0 software package and publication bias was investigated by Begg’s funnel plot.
