Blood Sample Protein Measurement Analysis

g Veterans, yet validated circulating biomarkers that predict treatment response or early disease progression are lacking. Current clinical decision-making relies primarily on PSA kinetics and radiographic imaging, which have well-recognized limitations in sensitivity and lead time. The goal of the

research study is to generate reproducible, high-quality proteomic data from the study�s longitudinal plasma specimens so that the VA study team can conduct exploratory analyses linking circulating proteomic changes to clinical outcomes, ul
