Abstract

Objective: To explore whether the functional chemokine receptor 5 delta32 (CCR5-Δ32) polymorphism is associated with susceptibility to cancer. Methods: A meta-analysis was conducted on the association between the CCR5-Δ32 polymorphism and cancer using (i) allele contrast and (ii) the dominant model. Results: Thirteen articles, including 16 comparative studies on a total of 3087 patients and 3735 controls, were included in the meta-analysis. These studies encompassed breast cancer (n = 3), bladder cancer (n = 3), cervical cancer (n = 2), pancreatic cancer (n = 2), prostate cancer (n = 2), head and neck cancer (n = 2), lymphoma (n = 1), gallbladder cancer (n = 1), skin cancer (n = 1) and mixed cancer (n = 1). The meta-analysis revealed an association between cancer and the CCR5-Δ32 allele (OR = 1.368, 95% CI = 1.064-1.758, p = 0.014), and stratification by ethnicity showed an association between the CCR5-Δ32 allele and cancer in Indians (OR = 2.480, 95% CI = 1.247-4.932, p = 0.010). The meta-analysis also revealed an association between breast cancer and the CCR5-Δ32 allele (OR = 1.689, 95% CI = 1.012-2.821, p = 0.045). However, allele contrast and the dominant model failed to reveal an association between the CCR5-Δ32 polymorphism and bladder cancer, cervical cancer, pancreatic cancer, prostate cancer, and head and neck cancer. Conclusions: This meta-analysis demonstrates that the CCR5-Δ32 polymorphism is associated with susceptibility to cancer in Indians and is associated with breast cancer.
