| Outline of Final Research Achievements |
We conducted a comprehensive epidemiological analysis of genetic and environmental factors to clarify the risk factors for prostate cancer (PCa) in Japanese nationals.
Result: 1) There are no significant increased risks of PCa on quantified nutrients at present. 2) Estrogen receptor 2 (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). 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.
