Routine annual imaging does not aid in diagnosing new functional complications more than five years after RC with ileal conduit.

Purpose: To assess the value of routine annual imaging in identifying complications more than 5 years after radical cystectomy (RC) with ileal conduit.

Methods: We included patients with bladder cancer who underwent RC with ileal conduit between 2011 and 2018. Patients were excluded if they received no functional follow up after discontinuing oncological follow up, if there was oncological progression or if an uretero-enteric structure (UES) was diagnosed within 5 years after RC.

Back-table specimen scanning using gantry-free hybrid hSPECT/LiDAR imaging: a feasibility study during PSMA-radioguided surgery.

Introduction: Prostate-specific membrane antigen (PSMA) targeted precision surgery is becoming increasingly popular. However, the relatively low levels of PSMA-receptor expression and background signal can hinder in vivo lesion detection and margin evaluation. Back-table imaging (ex vivo) potentially provides a means to confirm surgical accuracy.

Prognostic Stratification of pN1 Prostate Cancer After Radical Prostatectomy: A Competing Risk Analysis from a Multi-institutional Cohort.

Background And Objective: Lymph node-positive (pN1) prostate cancer (PCa) is a heterogeneous disease, and a clear definition of prognostic groups is urgently needed. We aimed to assess cancer-related mortality (CRM) in different prognostic groups of pN1 patients, created based on the pathological PCa characteristics and number of positive lymph nodes (LN+).

Methods: We conducted a retrospective, multicentre cohort study including 894 patients with pN1 disease treated at 15 European high-volume centres.

Renal clearance of fluorescent agents can compromise image-guided surgery along the urinary tract.

Objectives: To study the effect of renally cleared fluorescent agents on image-guided surgery along the urinary tract by using the renally cleared, non-tumour-specific, fluorescent dye fluorescein.

Subjects And Methods: Sixteen patients who underwent robot-assisted radical prostatectomy (RARP) with lymph node dissection received an intradermal injection of fluorescein. The slow-release of the fluorescein from the skin into the lymph- and bloodstream were used as a pharmacokinetic model for slow release from receptor-targeted agents.

Evaluating follow-up in patients with lymph node-negative penile cancer at a high-volume centre.

Objectives: To evaluate the current European Association of Urology/American Society of Clinical Oncology follow-up (FU) schedule with routine use of ultrasonography (US) ± US-guided fine-needle aspiration cytology (FNAC) in patients with lymph node (LN)-negative penile squamous cell carcinoma (PSCC).

Patients And Methods: We evaluated FU outcomes for low-risk clinically LN-negative (cN0) and intermediate- to high-risk sentinel node (SN) negative (pathological N-stage [pN]0) patients with PSCC at a high-volume centre. We analysed routine inguinal US ± FNAC (in case of a suspicious LN) during FU.

Comparing AI and Manual Segmentation of Prostate MRI: Towards AI-Driven 3D-Model-Guided Prostatectomy.

: Robot-assisted radical prostatectomy (RARP) is a common treatment option for prostate cancer. A 3D model for surgical guidance can improve surgical outcomes. Manual expert radiologist segmentation of the prostate and tumor in prostate MRI to create 3D models is labor-intensive and prone to inter-observer variability, highlighting the need for automated segmentation methods.

Beyond Gleason grading: MRI radiomics to differentiate cribriform growth from non-cribriform growth in prostate cancer men.

Objective: To differentiate cribriform (GP4Crib+) from non-cribriform growth and Gleason 3 patterns (GP4Crib-/GP3) using MRI.

Methods: Two hundred and ninety-one operated prostate cancer men with pre-treatment MRI and whole-mount prostate histology were retrospectively included. T2-weighted, apparent diffusion coefficient (ADC) and fractional blood volume maps from 1.

Evaluation of short term surgical outcomes of radical prostatectomy in the decade following the introduction of minimum volume standards in the Netherlands.

Introduction: A minimum volume standard (MVS) of 20 radical prostatectomies (RPs) per institution per year was implemented in the Netherlands in 2014, and raised to 50 RPs in 2018 and 100 in 2019. This study aimed to evaluate the effects of implementing a MVS on the extent of care centralization and short term surgical outcomes.

Methods: All patients who underwent RP between 2014 and 2022 were identified in the nationwide Netherlands Cancer Registry.

How Does Routine Prostate-specific Membrane Antigen Positron Emission Tomography/Computed Tomography Modify the Current Management of Prostate Cancer? A Multidisciplinary View.

Background And Objective: Prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA-PET/CT) and new treatment modalities have expanded the possibilities for diagnosing and managing metastatic prostate cancer, but have also raised questions about their implementation in daily clinical practice. We sought consensus on definitions, preferred imaging modality for staging, and treatment selection in the era of next-generation imaging.

Methods: A modified Delphi method involved two voting rounds and a face-to-face multidisciplinary meeting with 40 Dutch prostate cancer (PCa) experts.

Prognostic Value of Cribriform and Intraductal Carcinoma in Grade Group 2 Prostate Cancer With and Without Synchronous Nodal Metastases at Radical Prostatectomy: Results From a Case-control Matched, Multicenter Study.

Objective: To evaluate the occurrence and the oncological predictive value of cribriform growth and/or intraductal carcinoma (CR/IDC) in patients with ISUP grade group (GG) 2 prostate cancer (PCa) at radical prostatectomy (RP) with and without synchronous nodal metastases in a multicenter, international cohort.

Methods: We identified 1060 patients who underwent RP with ISUP GG2 PCa at histopathology and a pelvic lymph node dissection from 3 tertiary referral centers. Of these, 79 (7.

Development and Validation of a Deep Learning Model Based on MRI and Clinical Characteristics to Predict Risk of Prostate Cancer Progression.

Purpose To validate a deep learning (DL) model for predicting the risk of prostate cancer (PCa) progression based on MRI and clinical parameters and compare it with established models. Materials and Methods This retrospective study included 1607 MRI scans of 1143 male patients (median age, 64 years; IQR, 59-68 years) undergoing MRI for suspicion of clinically significant PCa (csPCa) (International Society of Urological Pathology grade > 1) between January 2012 and May 2022 who were negative for csPCa at baseline MRI. A DL model was developed using baseline MRI and clinical parameters (age, prostate-specific antigen [PSA] level, PSA density, and prostate volume) to predict the time to PCa progression (defined as csPCa diagnosis at follow-up).

Surgical navigation for targeted retroperitoneal lymph-node removal: a randomised, controlled, phase 3 trial.

Background: Metastatic retroperitoneal lymph node dissection (LND) for nodal recurrence is applied for a variety of cancers, such as urological, gynaecological and rectal cancer. Precise localisation and resection of these lymph nodes (LNs) during surgery can be challenging, especially after previous radiotherapy or surgery. The objective of this study was to assess the added value of surgical navigation for targeted LND in the retroperitoneum.

Multicenter Evaluation of Morbidity and Predictors of Response to Imiquimod Treatment for Penile Intraepithelial Neoplasia.

Introduction And Objective: Imiquimod (IQ) is an immunomodulator used in the management of penile intraepithelial neoplasia (PeIN) lesions. However, IQ treatment may be associated with bothersome side effects (SEs). To date, studies reporting on this morbidity and evaluating predictors of response to IQ are scarce and included small cohorts.

Early Oncological Outcomes in Patients who Underwent Staging Prostate-specific Membrane Antigen Positron Emission Tomography/Computed Tomography Compared with Conventional Imaging Before Radical Prostatectomy and Extended Pelvic Lymph Node Dissection.

Background And Objective: Prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) is increasingly used for primary staging in prostate cancer. Owing to accurate detection of small metastases on PSMA-PET/CT, patient selection for robot-assisted radical prostatectomy (RARP) has likely changed. This study analyzes oncological outcomes in patients undergoing RARP and extended pelvic lymph node dissection (ePLND) after PSMA-PET/CT staging, compared with those without PSMA-PET/CT.

Experience of urologists, oncologists and nurse practitioners with mainstream genetic testing in metastatic prostate cancer.

Background: International guidelines recommend germline genetic testing for men with metastatic prostate cancer. If offered to all patients by genetic healthcare professionals, there will be insufficient capacity to cope with the high patient numbers. In a mainstreaming pathway, non-genetic healthcare professionals (ngHCPs) discuss and order germline genetic testing instead of referring patients to genetic healthcare professionals.

Multispectral Fluorescence Imaging as a Tool to Distinguish Pelvic Lymphatic Drainage Patterns During Robot-assisted Lymph Node Dissection in Prostate Cancer.

Background: The invasive nature of extended pelvic lymph node dissection (ePLND) prompts the need for alternative lymphatic mapping technologies. To change the focus to "sparing nodes that are not involved," the first step is to research the feasibility of intraoperatively distinguishing the lymph drainage patterns of the prostate from healthy organs.

Methods: We performed a prospective study (NCT05120973) that included 16 patients who underwent a robot-assisted radical prostatectomy + ePLND + sentinel node (using indocyanine green-Tc-nanocolloid).

Staging Accuracy and Prognostic Value of Prostate-Specific Membrane Antigen PET/CT Strongly Depends on Lymph Node Tumor Burden.

: To explore the factors affecting the lymph node metastasis (LNM) detection performance of prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT) and to evaluate its prognostic value for biochemical recurrence after radical prostatectomy (RP). : Patients who had intermediate- or high-risk prostate cancer and underwent robot-assisted (RA)RP between 2017 and 2021 were included. Initial lymph node staging was carried out using PSMA PET/CT.

The effect of PSMA PET/CT on clinical decision-making of radical prostatectomy and pelvic lymph node dissection.

Objective: To evaluate the effect of prostate-specific membrane antigen (PSMA) PET/computed tomography (CT) on clinical decision-making of radical prostatectomy (RP) and pelvic lymph node dissection (PLND) after its utilization in daily clinical practice at an European high-volume cancer center.

Materials And Methods: Patients who had unfavorable intermediate- and high-risk prostate cancer between 2017 and 2021 were included retrospectively and divided into two groups; those who staged using PSMA PET/CT (group 1) and those who staged using conventional modalities (group 2). Clinical decision-making of RP over nonsurgical treatments and f PLND were primary endpoints and evaluated using regression models.
