Diagnostic Properties of Total and Free Prostate-Specific Antigen to Predict Overall and Clinically Significant Prostate Cancer Among Men With Low Testosterone and Prior Negative BiopsyTo evaluate whether total serum PSA, free-PSA ratio and PSA density have similar diagnostic properties for detecting prostate cancer (PCa) and clinically-significant (cs) PCa in men with normal testosterone compared to men with low testosterone with a prior negative biopsy.
Timing of Prostate-specific Antigen Nadir After Radical Prostatectomy and Risk of Biochemical RecurrenceTo evaluate the association between the prostate-specific antigen (PSA) nadir level and the time to nadir (TTN) with biochemical recurrence (BCR) risk after radical prostatectomy (RP) in the Shared Equal-Access Research Cancer Hospital (SEARCH) database.
Is Body Mass Index the Best Adiposity Measure for Prostate Cancer Risk? Results From a Veterans Affairs Biopsy CohortTo test multiple adiposity measures and prostate cancer (PC) risk in men undergoing prostate biopsy. We hypothesized that body mass index (BMI), body fat, and waist circumference would be highly correlated, and all would be associated with aggressive PC, but not overall risk.
Extent of Baseline Prostate Atrophy Is Associated With Lower Incidence of Low- and High-grade Prostate Cancer on Repeat BiopsyTo evaluate whether baseline prostate atrophy (PA) extent is associated with prostate cancer (PCa) incidence at 2-year repeat prostate biopsy in a clinical trial with systematic biopsies.
