Incorporation of urinary prostate cancer antigen 3 and TMPRSS2:ERG into Prostate Cancer Prevention Trial Risk Calculator.
The objective of this study was to determine whether the incorporation of two urinary markers, prostate cancer antigen 3 (PCA3) and TMPRSS2:ERG (T2:ERG), into the Prostate Cancer Prevention Trial Risk Calculator (PCPTRC) tool improves its discrimination, accuracy, and clinical net benefit. A Bayesian modeling approach was used to combine data where the markers were measured in a Michigan cohort with the PCPTRC as prior probabilities to create an updated PCPTRC; this update was compared to the existing PCPTRC in terms of discrimination, calibration, and decision curve analysis. Net benefit was improved for the updated PCPTRC, but calibration was not. The authors note that, the updated PCPTRC is limited since it was based on two separate cohorts, and further validation is required. The updated tool is available online.

Association between androgen deprivation therapy use and diagnosis of dementia in men with prostate cancer.
The purpose of this study was to analyze the association between androgen deprivation therapy (ADT) exposure and diagnosis of Alzheimer disease or dementia among elderly men with prostate cancer. Results showed that, among elderly patients with prostate cancer, ADT exposure was associated with subsequent diagnosis of Alzheimer disease or dementia over a follow-up period of at least 10 years.
