AbstractThe possible effect of prostate-specific antigen (PSA) testing on prostate cancer mortality has remained controversial, despite the test's widespread application. We examined age-specific mortality trends for prostate cancer in Austria before and after the introduction of (opportunistic) PSA testing, to ask whether PSA screening reduces prostate cancer mortality in a uniform cohort of men with equal access to health care. Prostate cancer mortality data covering all 9 federal states of Austria were analysed from 1970 to 2002. PSA testing became widely available in Austria not before 1989. Tyrol, one of the nine federal states of Austria, independently launched a mass prostate cancer prevention project in 1993. We applied join-point regression models to identify changes in the slope of age-specific mortality trends in selected age groups (50-59, 60-69, 70-79, and 80-89 years) and calculated the annual percent change (APC) in mortality between 1970 and 2002 for Tyrol and the rest of Austria separately. After 12 years of follow-up, we were not able to observe a significant reduction in prostate cancer mortality since the introduction of the PSA test in the age groups of 50-59, 60-69, and 80-89 years. A significant decrease was found in the age group of 70-79 (Austria without Tyrol 1989 through 2002: APC, -2.36; 95% CI, -3.38 to -1.34; Tyrol 1991 through 2002: APC, -6.42; 95% CI, -8.92 to -3.86). In this age group the join points 1989 and 1991 cannot be related to PSA testing. PSA screening does not appear to reduce prostate cancer mortality in a uniform cohort of men with equal access to health care. However, given the long lead-time for prostate cancer, even longer follow-up may still be needed to detect any important trends.
