The objective of this study is to assess the independent and joint effects of genetic and lifestyle factors on the risk of developing bladder cancer and age at diagnosis. METHODS: This is a population-based cohort study of the UK Biobank, consisting of 3,373 bladder cancer cases and 481,275 controls. A polygenic risk score (PGS) was constructed and the effect of lifestyle and genetic factors on bladder cancer risk and age at diagnosis were assessed. RESULTS: The PGS was an independent predictor of the risk of incident bladder cancer diagnosis (hazard ratio [HR] = 1.15, 95% confidence interval [CI]: 1.14-1.17, p<0.001) and earlier age at diagnosis (β = -0.30, standard error (SE) = 0.02, p<0.001). Additive joint effects with body mass index (BMI) and smoking status were observed. The study is limited by lack of pathologic data and inability to generalize results to populations of non-European ancestry. CONCLUSIONS: The PGS was an independent and significant predictor of the risk of bladder cancer and earlier age at diagnosis. Joint effects were observed with smoking status and BMI. These data provide support for incorporating measures of genetic risk factors in efforts to improve early detection of bladder cancer.
