Are annual PSA tests necessary for men with a PSA level below 2 ng/mL : findings of the Imari prostate cancer screening program?
Levels of PSA in men with an initial level below 2 ng/mL remained stable for up to 5 years. Levels of PSA in 97.8- 98.8% of men remained below 3 ng/mL after 1 to 5 years. In contrast, 18-35.3% of men with an initial PSA level between 2.1 and 3 ng/mL showed PSA progression to 3.1 ng/mL or more within 5 years. Our present data suggest that annual PSA testing is not necessary for men with a PSA level below 2 ng/mL. Prostate specific antigen testing could therefore be conducted at longer intervals in such individuals.
These data suggest that practice specialty, not the time since the course was taken, made a significant difference in the knowledge of recognition and reporting of child abuse.
