Estimate of population coverage with the prostate specific antigen (PSA) test to screen for prostate cancer in a metropolitan area of northern Italy.

The use of the prostate specific antigen (PSA) test in the period 1999-2000 in a population of 311 822 men, aged 40 years or more, resident in Milan, Italy, was examined. Data were drawn from the outpatient database of the local health information system. A total of 139 350 PSA tests were used in 83 943 subjects. Overall, 26.9% of the male population aged 40 or older, with no history of prostate cancer, received a PSA test in the 2 year study period. For subjects older than 50 the rate rose to 34%. Results show a high coverage of the male population in northern Italy with screening using the PSA test for prostate cancer.
