A meta-analysis of the relationship between paraoxonase 1 polymorphisms and cancer

Abstract

Some previous studies already explored associations between paraoxonase 1 (PON1) polymorphisms and cancer, with conflicting findings. Here, we aimed to better analyse the relationship between PON1 polymorphisms and cancer in a larger combined population by performing a meta-analysis. We searched PubMed, Embase, and Web of Science for related articles. We calculated odds ratio (OR) and 95% confidence interval (CI) to estimate whether there are genetic associations between PON1 polymorphisms and cancer. Forty studies were included for this meta-analysis. The PON1 rs854560 polymorphism (L55M) was found to be significantly associated with cancer in general population (dominant comparison: p = .04, OR = 0.85, 95%CI 0.73–0.99; recessive comparison: p = .007, OR = 1.27, 95%CI 1.07–1.51; allele comparison: p = 0.02, OR = 0.85, 95%CI 0.75–0.97). Subgroup analyses indicated that the significant findings were mainly driven by the haematological tumours and breast cancer subgroups. We did not observe any positive findings for PON1 rs662 polymorphism (Q192R) in combined analyses. In summary, this meta-analysis proved that PON1 rs854560 polymorphism could be used to identify individual with elevated susceptibility to cancer, especially for haematological tumours and breast cancer.
