RESUMEN
OBJECTIVE: [corrected] To describe the evolution of prostate cancer mortality in Spain during the period 1991-2005. SUBJECTS AND METHODS: A trend analysis for age standardized mortality rates (European standard population) was performed, using joinpoint regression analysis, which allows estimation of the annual percent change of rates and to find significant changes in such trend. RESULTS: Age standardized mortality rates in Spain reached their peak value in 1996. The joinpoint analysis identified two different periods in the trend of the age standardized rates: a first one of increase in rates between 1991 and 1996 (2.1% annual increase) and a second period starting in 1996, in which rates decline at an annual rate of 2.7%. CONCLUSION: The tendency of prostate cancer seen in Spain resembles that of industrialized areas, with an increase in its age standardized death rates that suffers a downturn by the end of the past decade. Mortality declines for prostate cancer are now evident in 14 out of the 17 Autonomous Communities. Increases in PSA screening and better treatment of early-stage disease, possibly acting in combination, remain plausible hypotheses.
