When patients were grouped according to smoking status, the ESR2 rs1256049 AA genotype (OR = 0.48, 95 % CI 0.25-0.95, P < 0.05) and ESR2 rs4986938 AG + AA genotype (OR = 0.64, 95 % CI 0.41-1.00, P < 0.05) showed significantly decreased PCa risk in the ever-smoker group.
ESR2 rs4986938 AG and AG + AA genotypes were associated with significantly decreased risk of PCa (AG: OR = 0.68, 95 % CI 0.47-0.97, P < 0.05 and AG + AA: OR = 0.67, 95 % CI 0.47-0.94, P < 0.05).
In conclusion, this meta-analysis indicated that ESR1 rs9340799 polymorphism was associated with prostate cancer risk in overall populations, Caucasians and Africans, while ESR2 rs1256049 polymorphism was associated with prostate cancer risk in Caucasians.
Estrogen receptors alpha (rs2234693 and rs9340799), and beta (rs4986938 and rs1256049) genes polymorphism in prostate cancer: evidence for association with risk and histopathological tumor characteristics in Iranian men.

However, an interactive association with BMI was observed in the relationship between prostate cancer risk and genotypes of ESR2 38 bp 3' of STP G>A (rs4986938) (p = 0.031).
We identify two independent susceptibility loci for prostate cancer at 11p15.4 (rs12791447, P=3.59 × 10(-8); PPFIBP2) and 14q23.2 (rs58262369, P=6.05 × 10(-10); ESR2).
Results from this study showed that six single base-pair polymorphisms (SNPs) of ESR1 (rs1801132, rs2077647, rs746432, rs2273206, rs851982, rs2228480) and four SNPs of ESR2 (rs4986938, rs928554, rs8018687, rs number not available for ESR2 5696 bp 3' of STP A>G) were not significantly associated with prostate cancer risk, either by allelic or genotypic frequencies.
