Abstract
Abstract Background The study aimed to test the hypothesis that endogenous testosterone density (ETD), in the low through favorable intermediate PCa risk classes patients undergoing surgery, might be associated with disease progression. Materials and methods ETD, PSAD, and percentage of biopsy positive cores density (BPCD) were calculated in relation to prostate volume (PV). Tumor load density (TLD) was estimated as the tumor load (TL) ratio to prostate weight. ET was considered low if 2), upstaging (pT > 2) and their related features were investigated. Results 433 patients were included, 249 (57.5%) from the favorable intermediate-risk class. Upgrading occurred in 168 (38.8%) cases and upstaging in 62 (14.3%). ETD above the median (9.9 ng/(dL x mL)), was discriminated by PSAD (AUC = 0.719; 95% CI: 0.671–0.766; p
