Abstract:
Purpose:To determine an appropriate surgical technique, it is important to predict pathological results for patientswith clinically localized prostate cancer (PCa) eligible for nerve-sparing radical prostatectomy (NSRP). Severalstudies have highlighted that serum testosterone level was associated with aggressive features of PCa. Therefore,we analyzed factors, including serum testosterone, to predict upstaging and upgrading after surgery for patientswith clinically localized PCa eligible for NSRP.
Materials and Methods:We retrospectively evaluated patients who underwent radical prostatectomy (RP) betweenJanuary 2015 and May 2018 at our institution. Patients with Gleason grade group 1 or 2 on biopsy,prostate-specific antigen<10, and ≤clinical/radiologic stage T2 were included in this study. Upstaging andupgrading were defined as pathological stage≥T3a and Gleason grade group≥3, respectively. We evaluatedthe patients’ demographics and outcomes according to upstaging and upgrading after surgery. Predictive factorsfor upstaging and upgrading were analyzed using a multivariate logistic regression model.
Results:Of 108 patients included in the study, upstaging and upgrading after surgery were observed in 24 (22.2%)and 36 (33.3%), respectively. Low serum testosterone level, small prostate size, and positive core number≥3on biopsy were identified as predictive factors for upstaging in multivariate analysis. Although serum testosteronewas associated with upgrading in univariate analysis, only clinical/radiologic stage and biopsy Gleason grade groupwere observed as predictive factors for upgrading in multivariate analysis.
Conclusions:Serum testosterone level was identified as a predictive factor for upstaging after RP for clinicallylocalized PCa eligible for NSRP.
