Background And Objective: Stockholm3 is a comprehensive blood test amalgamating protein biomarkers, genetic indicators, and clinical data to predict clinically significant prostate cancer risk (International Society of Urological Pathology grade ≥2 upon biopsy). Our study aims to externally validate Stockholm3 and compare its performance with the use of prostate-specific antigen (PSA) and the Rotterdam Prostate Cancer Risk Calculator (RPCRC) for clinically significant prostate cancer detection.
Methods: We gathered data from men subjected to prostate biopsies at the Martini-Klinik, Germany, between 2014 and 2017.
Objectives: To evaluate the long-term oncological outcomes and functional results of the neurovascular structure-adjacent frozen-section examination (NeuroSAFE) during nerve-sparing (NS) radical prostatectomy (RP).
Materials And Methods: A 10-yr survival analysis on 11069 RPs performed with or without the NeuroSAFE, between January 2002 to June 2011 was carried out. In the NeuroSAFE cohort, the neurovascular structure-adjacent prostatic margins are removed and stained for cryo-sectioning during RP.
Purpose: To compare oncological, functional, and surgical outcomes of a large cohort of patients who underwent open retropubic radical prostatectomy (ORP) or robot-assisted radical prostatectomy (RARP).
Materials And Methods: Data from 18,805 RPs performed with either the open or the robot-assisted approaches at a single tertiary referral center between 2008 and 2022 were analyzed. The impact of surgical approach on biochemical recurrence-free survival, salvage radiotherapy-free survival, and metastasis-free survival was analyzed by log-rank test and Kaplan-Meier analysis in a propensity score (PS)-based matched cohort.
Background: Intraoperative impairment of cerebral autoregulation (CA) has been associated with perioperative neurocognitive disorders. We investigated whether intraoperative fluctuations in cardiac index are associated with changes in CA.
Methods: We conducted an integrative explorative secondary analysis of individual-level data from 2 prospective observational studies including patients scheduled for radical prostatectomy.
Introduction: Prostate cancer (PCa) detection is usually achieved by PSA measurement and, if indicated, further diagnostics. The recent EAU guidelines recommend a first PSA test at the age of 50 years, if no family history of PCa or BRCA2 mutation exists. However, some men might harbor significant PCa at younger age; thus we evaluated the histopathological results of men treated with radical prostatectomy (RP) in their 40 s at our institution.

Patients And Methods: Proclarix and PHI were measured using samples of 344 men from two different centers.
Background: We compared six commonly used logistic regression methods for accommodating missing risk factor data from multiple heterogeneous cohorts, in which some cohorts do not collect some risk factors at all, and developed an online risk prediction tool that accommodates missing risk factors from the end-user.
Methods: Ten North American and European cohorts from the Prostate Biopsy Collaborative Group (PBCG) were used for fitting a risk prediction tool for clinically significant prostate cancer, defined as Gleason grade group ≥ 2 on standard TRUS prostate biopsy. One large European PBCG cohort was withheld for external validation, where calibration-in-the-large (CIL), calibration curves, and area-underneath-the-receiver-operating characteristic curve (AUC) were evaluated.
Background: We aimed to determine the concordance between the radiologic stage (rT), using multiparametric magnetic resonance imaging (mpMRI), and pathologic stage (pT) in patients with high-risk prostate cancer and its influence on nerve-sparing surgery compared to the use of the intraoperative frozen section technique (IFST).
Methods: The concordance between rT and pT and the rates of nerve-sparing surgery and positive surgical margin were assessed for patients with high-risk prostate cancer who underwent radical prostatectomy.
Results: The concordance between the rT and pT stages was shown in 66.
Context: Meticulous knowledge about the anatomy of the prostate and surrounding tissue represents a crucial and mandatory requirement during radical prostatectomy for reliable oncological and excellent replicable, functional outcomes. Since its introduction two decades ago, robotic-assisted laparoscopic radical prostatectomy (RALP) has evolved to become the predominant surgical approach in many industrialized countries.
Objective: To provide and highlight currently available literature regarding prostate anatomy and to help in improving oncological and functional outcomes in RALP.
Purpose: The objective of this study was to determine the influence of postanesthesia care unit (PACU) delirium on self-reported cognitive function and perceived health status 3 months after surgery.
Methods: This prospective observational cohort study was performed in a PACU at a high-volume prostate cancer center. We used a convenience sample of patients > 60 years undergoing elective radical prostatectomy.
Background: The risk of high-grade prostate cancer, given a family history of cancer, has been described in the general population, but not among men selected for prostate biopsy in an international cohort.
Objective: To estimate the risk of high-grade prostate cancer on biopsy based on a family history of cancer.
Design, Setting, And Participants: This is a multicenter study of men undergoing prostate biopsy from 2006 to 2019, including 12 sites in North America and Europe.
This report details how principal component analysis (PCA) can be used as a valuable tool to dissociate latent ERP components, even when considerable temporal and spatial overlap makes it difficult to discern ERP effects in standard time windows. We illustrate our methodological approach in a data set from a recognition memory paradigm, in which event-related potential (ERP) correlates of familiarity, recollection and the late parietal negativity (LPN) were partially overlapping. By adapting standard time windows based on the results of a temporo-spatial PCA, small yet reliable ERP correlates reflecting familiarity and recollection for identical items and late recollection for changed items were identified, complementing the result pattern observed in behavioral performance.

While prostate volume predicts biopsy outcome, it requires an imaging procedure for measurement. The four kallikrein panel - commercially available as the 4Kscore - predicts risk of GG2+ disease and requires only a blood draw.

We hypothesized that patients with DNCR in the early postoperative period would report reduced health-related quality of life (HRQoL) and more cognitive failures 12 months after surgery, compared with patients without DNCR.
Methods: We performed a 12-month follow-up on 367 patients who had been enrolled in a prospective observational trial to study the incidence of DNCR after radical prostatectomy.
Objective: Anoctamin 7 (ANO7) is a calcium-dependent chloride ion channel protein. Its expression is restricted to prostate epithelial cells. The exact function is unknown.

Emerging research has revealed that upregulation of TRIM24 in numerous tumor types is linked to poor prognosis, attributing an important role to TRIM24 in tumor biology. In order to better understand the role of TRIM24 in prostate cancer, we analyzed its immunohistochemical expression on a tissue microarray containing >17,000 prostate cancer specimens.

Patients And Methods: A total of 984 men were prospectively enrolled at three academic centres. The primary outcome was GG ≥2 on prostate biopsy.
Objective: Coronavirus disease-19 (COVID-19) pandemic caused delays in definitive treatment of patients with prostate cancer. Beyond the immediate delay a backlog for future patients is expected. The objective of this work is to develop guidance on criteria for prioritisation of surgery and reconfiguring management pathways for patients with non-metastatic prostate cancer who opt for surgical treatment.
