Effect of prostate cancer severity on functional outcomes after localized treatment: comparative effectiveness analysis of surgery and radiation study results.
The purpose of this study was to determine whether differences in predicted function over time between radical prostatectomy (RP) or external beam radiotherapy (EBRT) for localized cancer varied by risk group. Patient-reported, disease-specific function was measured using the Expanded Prostate Index Composite and predicted function was estimated using regression models, compared by disease risk. The study found that sexual function was similar between surgery and radiation for patients with high-risk disease, and the authors conclude that high-risk patients undergoing radiation therapy should be counseled that their sexual function may not be as good as low-risk patients also undergoing radiation.

Racial and ethnic disparities in substance use disorders and outcomes in elderly prostate cancer patients.
This study used Surveillance, Epidemiology, and End Results (SEER)-Medicare linked data to identify prevalence of substance use among patients with advanced-stage prostate cancer. There are racial and ethnic disparities between substance use and outcomes. A multidisciplinary coordinated care approach is recommended to address these disparities.
