Vitamin D receptor FokI, BsmI, ApaI, and TaqI polymorphisms and susceptibility to ovarian cancer: a meta-analysis

Abstract

Objective: The goal of this study was to explore whether vitamin D receptor (VDR) polymorphisms are associated with susceptibility to ovarian cancer.

Methods: Meta-analyses were conducted on the associations between the VDR FokI, BsmI, ApaI, and TaqI polymorphisms and ovarian cancer.

Results: A total of 12 comparison studies were considered in the meta-analysis, which involved 3716 patients and 5059 controls. Meta-analysis of the VDR FokI polymorphism showed an association between ovarian cancer and the f allele in European populations (OR = 1.094, 95% CI = 1.028–1.163, p = 0.004). Meta-analysis revealed an association between ovarian cancer and the ApaI A allele in all study subjects and Europeans as a sub-group (OR = 1.235, 95% CI = 1.019–1.497, p = 0.032 and OR = 1.287, 95% CI = 1.029–1.609, p = 0.027, respectively). No association was found between ovarian cancer and the BsmI and Taq polymorphisms (OR for B allele = 1.084, 95% CI = 0.936–1.255, p = 0.280, OR for the T allele = OR = 0.847, 95% CI = 0.706–1.270, p = 0.716).

Conclusions: This meta-analysis suggests that the VDR FokI and ApaI polymorphisms are associated with susceptibility to ovarian cancer in European populations.
