Lesional volume in the prediction of clinically significant prostate cancer.

Background: While MRI has significantly advanced risk stratification in prostate cancer, PIRADS scoring alone is still insufficient to solely determine which patients do not require biopsy. Beyond PIRADS scoring, data regarding lesional volume and number can easily be extracted. This study aims to investigate whether the novel parameter 'Lesional PSAD' is a better predictive biomarker for clinically significant prostate cancer than conventional PSAD.

BCG response and oncological outcomes in high risk nonmuscle invasive bladder cancer following previously treated upper tract urothelial carcinoma: A propensity-matched analysis.

Introduction: Metachronous bladder recurrences after prior treatment for primary upper tract urothelial carcinoma (UTUC) can occur in ∼3% to 50% of patients. Because UTUC demonstrated distinct molecular alterations, bladder recurrences in these patients may be molecularly and phenotypically different compared to primary bladder carcinoma. We aim to study the BCG efficacy in patients with primary high risk nonmuscle invasive bladder cancer (P-NMIBC) and metachronous bladder recurrences after previous nephroureterectomy for UTUC (M-NMIBC).

Preoperative prostatic artery embolization before transurethral resection of the prostate for prostate glands larger than 80 mL: the first randomized controlled trial.

Background: This study aimed to evaluate the impact of preoperative prostate artery embolization (PAE) on intraoperative blood loss during transurethral resection of the prostate (TURP) in glands larger than 80 cc.

Material And Methods: A prospective, surgeon-blinded randomized controlled clinical trial was conducted at a single tertiary center. Patients with a prostate volume of more than 80 cc with indications for TURP were randomized (1:1) to the following groups: preoperative prostatic artery embolization followed by TURP (Group A-intervention arm) and TURP alone (Group B-control arm).

Trimodality therapy versus radical cystectomy for muscle-invasive bladder cancer: A systematic review and meta-analysis.

Background: Radical cystectomy (RC) is the guideline-recommended gold standard of curative treatment for muscle-invasive bladder cancer (MIBC). Trimodality therapy (TMT) has recently emerged as a viable alternative treatment, aiming to improve long term survival and bladder preservation rates.

Methods: A systematic literature search was conducted on PubMed, Embase, Scopus and CENTRAL for randomized trials or covariate-matched studies comparing RC versus TMT for MIBC.

Multiparametric MRI before and after Focal Therapy for Prostate Cancer: Pearls and Pitfalls for the Reporting Radiologist.

In this era of personalized precision medicine, the accuracy of multiparametric MRI (mpMRI) and targeted biopsy in helping detect low-volume clinically significant prostate cancer has rekindled interest in focal therapy for primary prostate cancer. Such therapy may reduce the debilitating morbidity of radical whole-gland treatment. Post-focal therapy mpMRI surveillance is critical for assessing oncologic efficacy.

Deferred cytoreductive nephrectomy in patients with metastatic renal cell carcinoma: A systematic review and patient-level meta-analysis.

There has been much controversy regarding the order in which cytoreductive nephrectomy (CN) and systemic therapy (ST) are applied for patients with metastatic renal cell carcinoma (mRCC). We aimed to investigate the role of deferred CN (dCN) in mRCC, particularly in the current era of immunotherapy. A systematic literature search was conducted on PubMed, Embase, and Scopus for studies comparing dCN versus any non-dCN strategy, in any temporal sequence, with the provision of Kaplan-Meier curves for overall survival (OS).

Unravelling the natural history of localised prostate cancer in the post-prostate specific antigen era: implications for clinical management.

Background: Management of localised prostate cancer (PCa) remains controversial in the era of prostate-specific antigen (PSA) testing. This study aims to describe the natural history of men with PCa being followed up expectantly to evaluate disease mortality.

Methods: After exclusion, clinical data of 204 patients retrieved from a prospective large PCa registry were reviewed.

Radiation-Induced Hemorrhagic Cystitis in Prostate Cancer Survivors: The Hidden Toll.

: Radiation therapy (RT) plays a crucial role in managing prostate cancer, offering effective disease control and improving survival rates in both localized and recurrent cases. However, RT can lead to hemorrhagic cystitis, a significant late complication resulting in chronic morbidity and other health issues. This study aims to evaluate the real-world incidence of radiation-induced hemorrhagic cystitis requiring surgical intervention.

Lost opportunities: the underutilization of castrate-resistant prostate cancer treatment in real-world settings.

Background: Various treatment regimens are now available for metastatic castrate-resistant prostate cancer (CRPC). This work evaluates the real-world prescription patterns of CRPC in a large tertiary care center and the factors influencing them.

Methods: Health records of 330 patients with metastatic hormone-sensitive prostate cancer (HSPC), treated and progressed to CRPC between 2016 and 2020, were reviewed from a prospective uro-oncological database.

Corrigendum to "Surveillance one year post focal cryotherapy for clinically significant prostate cancer using mpMRI and PIRADS v2.1: An initial experience from a prospective phase II mandatory biopsy study" [Eur. J. Radiol. Open 11 (2023) 100529].

Cardio-oncology in advanced prostate cancer.

Treatment intensification with androgen deprivation therapy (ADT) and androgen receptor pathway inhibitors (ARPi) have led to improved survival in advanced prostate cancer. However, ADT is linked to significant cardiovascular toxicity, and ARPi also negatively impacts cardiovascular health. Together with a higher prevalence of baseline cardiovascular risk factors reported among prostate cancer survivors at diagnosis, there is a pressing need to prioritise and optimise cardiovascular health in this population.

"Seeing Is Believing": Additive Utility of Ga-PSMA-11 PET/CT in Prostate Cancer Diagnosis.

Widespread adoption of mpMRI has led to a decrease in the number of patients requiring prostate biopsies. Ga-PSMA-11 PET/CT has demonstrated added benefits in identifying csPCa. Integrating the use of these imaging techniques may hold promise for predicting the presence of csPCa without invasive biopsy.

Off-clamp vs on-clamp robot-assisted partial nephrectomy: a systematic review and meta-analysis.

Objective: To compare intra- and postoperative outcomes between off-clamp and on-clamp robot-assisted partial nephrectomy (RAPN), using data from randomised controlled trials (RCTs) or covariate-matched studies (propensity score-matched or matched-pair analysis).

Methods: A Preferred Reporting Items for Systematic Reviews and Meta-Analyses-compliant literature review was conducted on PubMed, EMBASE, Scopus and CENTRAL for relevant studies comparing off-clamp to on-clamp RAPN. Primary outcomes were estimated blood loss, postoperative percentage decrease in estimated glomerular filtration rate (eGFR), and margin positive rate.

Far from the truth: Real-world treatment patterns among newly diagnosed metastatic prostate cancer in the era of treatment intensification.

Objectives: Real-world uptake of treatment intensification (TI) with novel hormonal agents (NHA) or chemotherapy as treatment of metastatic prostate cancer remains low outside of trial settings. We aim to report the prescription patterns and treatment outcomes of de novo metastatic hormone-sensitive prostate cancer (mHSPC) in a tertiary institution.

Methods: This is a retrospective cohort study using real-world data from a prospectively maintained prostate cancer registry.

Intensive sampling of the umbra and penumbra improves clinically significant prostate cancer detection and reduces risk of grade group upgrading at radical prostatectomy.

Purpose: Our objective is to evaluate the clinically significant prostate cancer detection rate of overlapping and perilesional systematic biopsy cores and its impact on grade group (GG) concordance at prostatectomy.

Materials And Methods: Biopsy maps of those undergoing MRI-targeted (TB) and systematic biopsy (SB) were reviewed to reclassify systematic cores. Perilesional (PL) cores were defined as adjacent cores within 10 mm of the target lesion ("penumbra") whilst overlap (OL) cores were defined as cores within the ROI itself ("umbra").

Natural language processing in urology: Automated extraction of clinical information from histopathology reports of uro-oncology procedures.

Objectives: We aimed to automate routine extraction of clinically relevant unstructured information from uro-oncological histopathology reports by applying rule-based and machine learning (ML)/deep learning (DL) methods to develop an oncology focused natural language processing (NLP) algorithm.

Methods: Our algorithm employs a combination of a rule-based approach and support vector machines/neural networks (BioBert/Clinical BERT), and is optimised for accuracy. We randomly extracted 5772 uro-oncological histology reports from 2008 to 2018 from electronic health records (EHRs) and split the data into training and validation datasets in an 80:20 ratio.

Patient-reported functional outcomes and oncological control after primary focal cryotherapy for clinically significant prostate cancer: A Phase II mandatory biopsy-monitored study.

Introduction: We report herein the impact of focal therapy (FT) on multi-domain functional outcomes in a Phase II prospective clinical trial (NCT04138914) in focal cryotherapy for clinically significant prostate cancer (csPCa).

Methods: The primary outcome was the detection of a ≥5 point deterioration in any of the four main expanded prostate index composite (EPIC) functional domains. Pretreatment multiparametric magnetic resonance imaging (mpMRI) and transperineal targeted and systematic saturation biopsy were used to select patients with prostate-specific antigen (PSA)≤20 ng/mL, Gleason grade group (GG) ≤4, mpMRI lesion volume ≤ 3 mL (for a single lesion) or ≤1.

Clinicopathological features of non-conventional renal cell carcinoma histological subtypes: Learning points from a large contemporary series spanning over three decades.

Purpose: To perform a retrospective review of the clinicopathological features of patients with conventional and non-conventional renal cell carcinoma (cRCC and ncRCC).

Materials And Methods: A large prospectively maintained uro-oncological registry was accessed to extract clinicopathological data of patients diagnosed with renal tumors who subsequently underwent nephrectomy from 1990-2019. Demographics and operative parameters were extracted.

NEAR trial: A single-arm phase II trial of neoadjuvant apalutamide monotherapy and radical prostatectomy in intermediate- and high-risk prostate cancer.

Objective: Treatment efficacy of androgen deprivation therapy with radical prostatectomy for intermediate- to high-risk prostate cancer is less well-studied. The NEAR trial is a single-arm, phase II investigation of neoadjuvant apalutamide monotherapy and radical prostatectomy (RP) in the treatment of D'Amico intermediate- and high-risk prostate cancer (NCT03124433).

Materials And Methods: Patients with histologically-proven, D'Amico intermediate- to high-risk prostate adenocarcinoma received apalutamide 240 mg once-daily for 12 weeks followed by RP + /-lymphadenectomy.
