Article Title: A prospective study of the association between physical activity and risk of prostate cancer defined by clinical features and TMPRSS2:ERG
Abstract: Background: Growing evidence shows that clinical and molecular subtypes of prostate cancer (PCa)have specific risk factors. Observational studies suggest that physical activity may lower the risk of aggressive PCa. To our knowledge, the association between physical activity and PCa defined by TMPRSS2:ERG has not been evaluated. Objective: To prospectively examine the association between physical activity and risk of PCa defined by clinical features and TMPRSS2:ERG. Design, setting, and participants: We studied 49 160 men aged 40–75 yr in the Health Professionals Follow-up Study from 1986 to 2012. Data was collected at baseline and every 2 yr with >90% follow-up. Total and vigorous physical activity were measured in metabolic equivalent of task (MET)-h/wk. Outcome measures and statistical analysis: Advanced PCa was defined as stage T3b, T4, N1, or M1 at diagnosis and lethal PCa as distant metastases or death due to disease over follow-up. Presence of TMPRSS2:ERG was estimated by immunohistochemistry of ERG protein expression. Cox proportional hazards models were used to obtain multivariable hazard ratios (HRs)and 95% confidence intervals (CIs)for incidence of subtype-specific PCa. Results and limitations: During 26 yr of follow-up, 6411 developed PCa overall and 888 developed lethal disease. There were no significant associations between total physical activity and risk of PCa in the overall cohort. In multivariable-adjusted models, men in the highest quintile of vigorous activity had a significant 30% lower risk of advanced PCa (HR: 0.70, 95% CI: 0.53–0.92)and 25% lower risk of lethal PCa (HR: 0.75, 95% CI: 0.59–0.94)than men in the lowest quintile of vigorous activity. The association was independent of screening history. Vigorous activity was not associated with total PCa in the overall cohort but was inversely associated among highly screened men (top vs bottom quintile, HR: 0.83, 95% CI: 0.70–0.97). Of all cases, 945 were assayed for ERG (48% ERG-positive). Men with higher vigorous activity had a lower risk of ERG-positive PCa (top vs bottom quintile, HR: 0.71, 95% CI: 0.52–0.97). There was no significant association with the risk of ERG-negative disease (p heterogeneity = 0.09). Conclusions: Our study confirms that vigorous physical activity is associated with lower risk of advanced and lethal PCa and provides novel evidence for a lower risk of TMPRSS2:ERG-positive disease. Patient summary: The identification of modifiable lifestyle factors for prevention of clinically important prostate cancer (PCa)is needed. In this report, we compared risk of PCa in men with different levels of physical activity. Men with higher vigorous activity had a lower risk of developing advanced and lethal PCa and PCa with the common TMPRSS2:ERG gene fusion. © 2018 European Association of Urology In this prospective study of physical activity and prostate cancer among 49 160 men, vigorous activity was associated with lower risk of lethal and TMPRSS2:ERG-positive disease. Long-term vigorous activity may be beneficial in prevention of lethal prostate cancer and may involve pathways specific to TMPRSS2:ERG-positive disease. © 2018 European Association of Urology
