Prostate cancer screening practices in a large, integrated health system: 2007-2014.
The researchers assessed prostate cancer screening practices in primary care since the initial United States Preventive Services Task Force (USPSTF) recommendation against prostate-specific antigen (PSA) testing for older men. Prostate cancer screening declined from 2007 to 2014 even in higher-risk groups and follow-up screening rates were not related to previous PSA level.

Racial variation in patient-reported outcomes following treatment for localized prostate cancer: results from the CEASAR study.
This study tested the hypothesis that treatment-related changes in urinary, bowel, sexual, and hormonal function vary by race/ethnicity. It concluded that the effect of treatment for prostate cancer on patient-reported function did not vary dramatically by race/ethnicity. Compared to white men, African-American men experienced a somewhat more pronounced decline in urinary continence after radical prostatectomy.

Falls and frailty in prostate cancer survivors: current, past, and never users of androgen deprivation therapy.
This study compared the prevalence of and association between falls and frailty of prostate cancer survivors (PCSs) who were current, past or never users of androgen deprivation therapy (ADT). It concluded that current and past exposure to ADT is linked to higher risk of falls and frailty than no treatment.

Comparative effectiveness of prostate cancer treatments for patient-centered outcomes: a systematic review and meta-analysis (PRISMA compliant).
This review analyzed the comparative effectiveness of prostate cancer (PCa) treatments through systematic review and meta-analysis with a focus on outcomes that matter most to newly diagnosed localized PCa patients. The studies provided moderate data for the patient-centered outcome of mortality. Radical prostatectomy demonstrated mortality benefit compared to watchful waiting and radiation therapy.

Association between choice of radical prostatectomy, external beam radiotherapy, brachytherapy, or active surveillance and patient-reported quality of life among men with localized prostate cancer.
This study compared quality of life after radical prostatectomy, external beam radiotherapy, and brachytherapy vs active surveillance. By 24 months, mean scores between treatment groups vs active surveillance were not significantly different in most domains. However, each treatment strategy was associated with distinct patterns of adverse effects over 2 years.

Association between radiation therapy, surgery, or observation for localized prostate cancer and patient-reported outcomes after 3 years.
This study compares functional outcomes and adverse effects associated with radical prostatectomy, external beam radiation therapy (EBRT), and active surveillance. It concluded that radical prostatectomy was associated with a greater decrease in sexual function and urinary incontinence than either EBRT or active surveillance after 3 years and was associated with fewer urinary irritative symptoms than active surveillance.

More judicious use of expectant management for localized prostate cancer during the last 2 decades.
Urologists have been criticized for overtreating men with low risk prostate cancer and for passively observing older men with higher risk disease. Proponents of active surveillance for low risk disease and critics of watchful waiting for higher risk disease have advocated for more judicious use of observation. In this study, the investigator compared 2 population based cohorts to determine how expectant management has evolved during the last 2 decades.

Utilization and predictors of expectant management among elderly men with low-and intermediate-risk localized prostate cancer in U.S. urological practice.
Researchers assessed the use and predictors of expectant management (EM) to understand its uptake in U.S. practice. In U.S. practice, the utilization of EM steadily increased in low-risk prostate cancer and remained low in the intermediate-risk group over time. While patients with advanced age or comorbidities were more likely to receive EM, its use varied substantially by geographic region.

Physician recommendations trump patient preferences in prostate cancer treatment decisions.
This study assessed the influence of patient preferences and urologist recommendations in treatment decisions for clinically localized prostate cancer. It found that patients' initial treatment preferences did not predict receipt of active treatment versus surveillance. Instead, receipt of active treatment was predicted primarily by urologists' recommendations.
