Abstract
Objectives: To examine the association between fibroblast growth factor receptor-4 (FGFR-4) genetic polymorphisms (Gly-388Arg) and prostate cancer susceptibility. Methods: A comprehensive search was conducted to identify all case-control studies of FGFR-4 polymorphisms and prostate cancer risk. Statistical analysis was performed with the software program Stata, version 8.0, and Review Manage, version 4.2. Results: A total of 4 eligible studies, including 2,618 cases and 2,305 controls, relating the FGFR-4 polymorphism to the risk of prostate cancer were identified. The overall results indicated a significant association between FGFR-4 polymorphisms and prostate cancer. In the subgroup analysis by ethnicity, a significant association was found between European descent for recessive model (random effects OR 0.82, 95% CI 0.72–0.93) and co-dominant genetic model (random effects OR 0.83, 95% CI 0.68–1.00). Sensitivity analysis also found a significant association in the recessive (random effects OR 0.68, 95% CI 0.49–0.95) or the co-dominant (random effects OR 0.68, 95% CI 0.49–0.96) models. Egger’s test showed that publication bias was not present in any of the comparisons. Conclusions: Gly-388Arg polymorphism of FGFR-4 most likely contributes to susceptibility to prostate cancer, especially in men of European descent.
