Objective: To assess whether NADiA ProsVue prostate-specific antigen slope, a prognostic biomarker for identifying men at a reduced risk of clinically recurrent prostate cancer after radical prostatectomy, is prognostic for prostate cancer--specific mortality (PCSM) and other outcomes.
Materials And Methods: We examined long-term outcome in the cohort of 304 men selected for the ProsVue 510(k) clinical trial. We assessed the prognostic value of a ProsVue result ≤ 2.

Background: Selecting appropriate candidates for postprostatectomy radiotherapy is challenging, because adverse pathological features cannot accurately predict clinical recurrence. Biomarkers that identify residual disease activity may assist clinicians when counseling patients on the risks, benefits and costs of secondary treatment. NADiA ProsVue PSA slope results ≤2.

Materials And Methods: From 4 clinical sites, we selected a cohort of 304 men who had been followed up for 17.
Background: Serum prostate-specific antigen (PSA) concentrations after radical prostatectomy typically become undetectable with the use of current immunometric assay methods. Despite modern surgical techniques, 15%-30% of prostate cancer patients undergoing radical prostatectomy develop a biochemical recurrence during follow-up. Unfortunately, poor analytical sensitivity of standard PSA assays delays biochemical recurrence detection, and because of day-to-day assay imprecision ultrasensitive PSA assays cannot assess PSA kinetics.

This study summarizes patient- and treatment-related factors associated with a prolonged time off ADT in patients electing intermittent androgen deprivation (IAD).
Methods: Hormone-naïve patients with PC were treated with ADT using an antiandrogen and a luteinizing-hormone-releasing hormone-agonist.
