Association of angiotensin ?? type 1 receptor gene A1166C polymorphism with cancer risk: An updated meta-analysis.

ABSTRACT: OBJECTIVE::The association between angiotensin II type 1 receptor ( AGTR1) gene A1166C polymorphism and cancer risk has been investigated in many studies. However, the results have been inconclusive. A meta-analysis was performed to obtain a more precise estimation of the relationship. METHODS::The PubMed and China National Knowledge Infrastructure databases were searched for published literature. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strengths of association. RESULTS::Ten studies, including 1553 patients and 1904 controls, were included in the meta-analysis. Overall, there were no significant associations between the AGTR1 gene A1166C polymorphism and cancer risk in the general population (CC vs AA: OR = 1.09, 95% CI = 0.50-2.37; AC vs AA: OR = 1.54, 95% CI = 0.81-2.91; dominant model: OR = 1.46, 95% CI = 0.77-2.79; recessive model: OR = 1.12, 95% CI = 0.84-1.49). In a subgroup analysis by nationality and cancer type, the results also showed no association between this polymorphism and cancer risk. CONCLUSIONS::This meta-analysis demonstrated that the AGTR1 gene A1166C polymorphism does not appear to be related to the risk of cancer.
