National Prostate Cancer Screening Rates After the 2012 US Preventive Services Task Force Recommendation Discouraging Prostate-Specific Antigen–Based Screening
Menée aux Etats-Unis, cette étude évalue l'effet des recommandations 2012 de l'"US Preventive Services Task Force" sur la proportion d'hommes ayant subi un examen de dépistage du cancer de la prostate par dosage du PSA
Purpose : In 2012, the US Preventive Services Task Force (USPSTF) discouraged prostate-specific antigen (PSA) –based prostate cancer screening. Previous USPSTF recommendations did not appreciably alter prostate cancer screening. Therefore, we designed a trend analysis to determine the population-based impact of the 2012 recommendation.
Methods : The nationally representative National Health Interview Survey was used to estimate the proportion of men age 40 years and older who saw a physician and were screened for prostate cancer in 2013. An externally validated 9-year mortality index was used to analyze screening rates based on remaining life expectancy. Screening rates from 2005, 2010, and 2013 were compared using logistic regression.
Results : PSA-based screening did not significantly change from 2010 to 2013 among 40- to 49-year-old men (from 12.5% to 11.2%; P = .4). Screening rates significantly declined in men age 50 to 59 years (from 33.2% to 24.8%; P < .01), age 60 to 74 years (from 51.2% to 43.6%; P < .01), and age 75 years or older (from 43.9% to 37.1%; P = .03). A large percentage of men were screened for prostate cancer despite a high risk (> 52%) of 9-year mortality, including approximately one third of men older than age 75 years. Approximately 1.4 million men age 65 years or older with a high risk (> 52%) of 9-year mortality were screened in 2013.
Conclusion : Prostate cancer screening significantly declined among men older than age 50 years after the 2012 USPSTF guideline discouraging PSA-based screening. A significant proportion of men continue to be screened despite a high risk of 9-year mortality, including one third of men age 75 years and older.
