Pee test could spot prostate cancer early

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Individuals must meet all the following inclusion criteria in order to be eligible to participate in the study: * Provide signed and dated informed consent form (ICF) * Male * Patients must be 50-70 years of age (VPAC) or 50-75 (STEAP1) * Willing to comply with all study procedures VPAC Specific Aim 1 - Prostate Cancer, PCa (N = 150) * Known diagnosis of untreated prostate cancer, scheduled for robotic prostatectomy * No prior treatment (surgery, radiation, or medical therapy) Specific Aim 1.1 - Normal PSA (N = 125) * PSA \< or = 1.5 ng/ml within the last year * No diagnosis or suspicion of cancer anywhere along the genitourinary tract * No history of BPH Prostate VPAC Version 8.0 Protocol 20G.196 20 June 2025 Based on SKCC Interventional Protocol Template v.20170209 page 20 of 31 Specific Aim 1.2 - Benign Prostatic Hyperplasia, BPH (N = 100) * PSA \< or = 1.5 ng/ml within the last year * Previous history of PSA \>1.5 ng/ml are still eligible if they underwent surgery for the treatment of BPH and had a subsequent decrease in PSA below 1.5 ng/m * Has a diagnosis of BPH, BOO, or LUTS Specific Aim 2 - Persistently Elevated PSA, PE (N = 100) * Patients with a negative prostate biopsy within the last 1 year from the day of consent * At least two elevated PSA values, defined as 2.5 ng/dL or greater, with the most recent result being within the last 1 year from the day of consent, unless otherwise approved by the PI * HGPIN and ASAP are considered negative * Previous biopsy results, if a repeat prostate biopsy patient, do not need to be available, there is also no preferred timeframe of previous biopsy (can be \>1 year at time of consent) STEAP1 Specific Aim 1: To determine STEAPl receptor density as a function of PCa GGl to 5 using receptors specific immunohistochemistry Specific Aim 2: To determine STEAPl expression as a function of PCa GG, 1-5 using quantitative RtPCR. An individual who meets any of the following criteria will be excluded from participation in this study: * Subjects under the age of 50 or over the age of 70 (VPAC) or above 75 (STEAP1) * Individuals with any cancers along the genitourinary tract (does not include penile or testicular cancers) * Individuals taking finasteride or dutasteride, which decreases the PSA value * Individuals with gross hematuria suspicious of bladder cancer
