(HealthDay News) – Despite the 2008 changes in US Preventive Services Task Force (USPSTF) recommendations against prostate-specific antigen (PSA)-based screening for prostate cancer in men >75 years, screening rates remained unchanged for men of all ages between 2005–2010.
Sandip M. Prasad, MD, MPhil, of the University of Chicago Medical Center, and colleagues examined demographic, socioeconomic, and functional variables collected from men (aged >40 years) free of prostate cancer or other prostate-related conditions. The men participated in the 2005 (5,332 participants) and 2010 (4,640 participants) National Health Interview Survey and had visited a physician in the prior year.
The researchers found that PSA screening rates were unchanged over time in all age groups. PSA screening was unchanged between 2005–2010 in men >75 years (43 and 43.9%, respectively). PSA screening was more common in men aged >75 years (43.9%) than in men aged 40–49 years or 50–59 in 2010 (12.5 and 33.2%, respectively). But men aged 60–74 years had the highest screening rate (51.2%).
“The discrepancy between the USPSTF recommendation and subsequent practice patterns may reflect lack of guideline awareness, financial incentives, or patient or physician confidence in PSA screening,” the authors conclude.
