Performance of Inherited Risk Assessment for Predicting Prostate Cancer From Prostate Biopsy

Prostate Cancer Diagnosis from Prostate Biopsy Report

The primary outcome measure is prostate cancer diagnosis from the prostate biopsy report. The primary goal is to compare prostate cancer detection rate in patients of three inherited risk groups (high-risk, intermediate-risk, and low-risk).

The first type of secondary outcome measures is demographic key clinical variables from chart review, including

* Age of the patient at recruitment, measured in years * Ethnicity, which will be reported as either Hispanic or Latino, or not Hispanic or Latino * Race, which will be reported as Black/African American, East Asian, White, or Other * Most recent body mass index (BMI), which height and weight will be combined and reported in kg/m\^2 * Most recent PSA test result prior to prostate biopsy, which will be reported in ng/mL * Most recent prostate health index (PHI), which is a combination of three PSA-based blood tests that estimates the probability of having detectable prostate cancer * TRUS prostate volume, based on the height, length, and width of the prostate and will be reported in mL

The second type of secondary outcome measures is results from multi-parametric Magnetic Resonance Imaging (mpMRI), including

* Prostate total volume, measured in mL * Overall Prostate Imaging Reporting and Data System (PI-RAD) score, which assesses risk of clinically significant cancer being present or absent * Extraprostatic extension, which will be reported as present or absent * Seminal vesicle invasion, which will be reported as present or absent * Lymph node enlargement, which will be reported as present or absent * MRI bone metastasis, which will be reported as present or absent * Number of lesions, which will be reported as a numerical value * For each lesion, location of lesion, which will be reported as the anatomical region of the prostate where the lesion is present * For each lesion, size of lesion, measured in mm * For each lesion, PIRAD score of lesion, which assesses risk of clinically significant cancer being present or absent in the lesion

The third type of secondary outcome measures is pathological variables from prostate biopsy, including

* Type of prostate biopsy that was performed on the patient, which will be reported as either transperineal (TP) or transrectal ultrasound (TRUS) * Number of cores positive, which will be reported as a numerical value * Number of cores examined, which will be reported as a numerical value * Overall Gleason score (primary), which predicts cancer aggressiveness and prognosis * Overall Gleason score (secondary), which predicts cancer aggressiveness and prognosis * For each core, length of core, measured in cm * For each core, length of tumor, measured in mm * For each core, % of core positive, which will be reported as a numerical value as a percentage * For each core, % Gleason 4 * For each core, presence of perineural invasion (PNI), will be reported as Yes or No * For each core, presence of cribriform, will be reported as Yes or No
