Volume 20, Number 3Original ResearchHistologic Changes in Prostate Cancer Detected Subsequent to the 2012 United States Preventive Services Task Force (USPSTF) Prostate Cancer Screening RecommendationAnn E AndersonCarl A OlssonHugh J LaveryDeepak KapoorWe report changes in the histopathology of prostate cancer diagnosed in a large urology group practice after the final United States Preventive Services Task Force (USPSTF) Grade D recommendation against prostate-specific antigen screening. All prostate biopsies performed from 2011 through 2015 in a large urology group practice were retrospectively reviewed; 2012 was excluded as a transition year. The changes in biopsy data in years following the USPSTF decision (2013-2015) were then compared with baseline (2011). A total of 10,944 biopsies were evaluated during the study period. Positive biopsy rates rose from 39.1% at baseline to 45.2% in 2015 (P < 0.01) with a marked shift toward more aggressive cancer throughout the study period. The absolute number of patients presenting with Gleason Grade Group 4 or 5 increased from 155/year at baseline to 231, 297, and 285 in 2013, 2014, and 2015, respectively (P < 0.05), unrelated to age or racial changes over time. Black men represented 16% of the cohort. Since the USPSTF recommendation against prostate cancer screening, trends toward a substantial upward grade migration and increased volume of cancers were noted in a cohort of nearly 11,000 patients in a real- world clinical practice. Additionally, continuing reductions in cancer detection in the United States may exacerbate these trends.
