Changes in treatment and mortality in men with locally advanced prostate cancer between 2000 and 2016: a nationwide, population-based study in Sweden

• Objective: To evaluate whether the effects of radical treatment in men with locally advanced prostate cancer (PCa) on PCa mortality observed in randomised clinical trials are applicable on a population basis. Patients and methods: We conducted a population-based cohort study using the Prostate Cancer data Base Sweden of 20350 men diagnosed between 2000 and 2016 with locally advanced PCa, defined as clinical local stage T3/T4, M0, Mx and a prostate-specific antigen level of <100ng/mL. Cumulative PCa mortality was examined using competing risk analysis of all men with locally advanced PCa, and also including men who did not undergo radical treatment. Multivariate regression analysis, including prognostic factors, was used to calculate hazard ratios (HRs) for all-cause and PCa-specific death. Results: The proportion of men treated with primary radical radiotherapy (n=4174) or prostatectomy (n=1210) increased from 15% in 2000–2003, 25% in 2004–2007, 33% in 2008–2011 to 43% in 2012–2016. The corresponding 5-year PCa mortality decreased from 19%, 18%, 17%, to 15% for all men, with the steepest decrease in men aged 65–74years, from 16% to 8%. The risk of PCa mortality in men aged <80years was lower in the last period compared to the first period, with a HR of 0.65 (95% confidence interval 0.56–0.76) in multivariate analysis. Conclusions: The threefold increase in use of radical treatment was accompanied by a modest decrease in PCa mortality in all men with newly diagnosed locally advanced PCa. For men aged 65–74years, there was a 50% decrease in the relative risk of PCa death. This indicates that the benefits previously observed in randomised trials can also be achieved in a real-life setting. © 2020 The Authors BJU International published by John Wiley & Sons Ltd on behalf of BJU International
