Proficiency score as a predictor of early trifecta achievement during the learning curve of robot-assisted radical prostatectomy for high-risk prostate cancer: Results of a multicentric series.

Background: Recently, an innovative tool called "proficiency score" was introduced to assess the learning curve for robot-assisted radical prostatectomy (RARP). However, the initial study only focused on patients with low-risk prostate cancer for whom pelvic lymph node dissection (PLND) was not required. To address this issue, we aimed to validate proficiency scores of a contemporary multicenter cohort of patients with high-risk prostate cancer treated with RARP plus extended PLND by trainee surgeons.

Thermal Ablation for Small Renal Masses: Identifying Anthropometric Factors for Predicting Perioperative and Oncological Outcomes.

Objectives: To test for specific anthropometric parameters to predict perioperative outcomes after thermal ablation (TA) for renal cell carcinoma (RCC).

Materials And Methods: Retrospective single center (2008-2022) analysis of 538 T1a-b RCC patients treated with TA. We tested for specific anthropometric parameters, namely skin to tumor distance (STTD), perirenal fat thickness (PFT), median psoas muscle axial area (PMAA) and median paravertebral muscle axial area (PVMAA), to predict TRIFECTA achievement: (1) absence of CLAVIEN-DINDO≥ 3 complications; (2) complete ablation; (3) absence of ≥ 30% decrease in eGFR.

Background: We compared multimodality treatment (MMT, defined as robot-assisted radical prostatectomy (RARP) with androgen deprivation therapy (ADT), with or without adjuvant radiotherapy (RT)) vs. ADT alone in oligometastatic prostate cancer (OPC) patients. Methods: From 2010 to 2018, we identified 74 patients affected by cM1a-b OPC (≤5 metastases).

Neoadjuvant chemotherapy does not increase peri-operative morbidity following radical cystectomy.

Objective: To determine whether use of neoadjuvant chemotherapy (NAC) is associated with a higher risk of post-operative complications following radical cystectomy (RC) for bladder cancer (BCa).

Materials And Methods: We retrospectively reviewed records of patients undergoing RC for non-metastatic urothelial BCa at 13 tertiary care centres from 2007-2019. Patients who received NAC ('NAC + RC' group) were compared with those who underwent upfront RC ('RC alone' group) for intra-operative variables, incidence of post-operative complications as per the Clavien-Dindo classification (CDC) and rates of re-admission and re-intervention.

A comprehensive evaluation of sexual and reproductive outcomes following robot-assisted retroperitoneal lymph node dissection for nonseminomatous germ cell tumor.

Sexual disorders following retroperitoneal pelvic lymph node dissection (RPLND) for testis tumor can affect the quality of life of patients. The aim of the current study was to investigate several different andrological outcomes, which may be influenced by robot-assisted (RA) RPLND. From January 2012 to March 2020, 32 patients underwent RA-RPLND for stage I nonseminomatous testis cancer or postchemotherapy (PC) residual mass.

Diagnostic accuracy of preoperative lymph node staging of bladder cancer according to different lymph node locations: A multicenter cohort from the European Association of Urology - Young Academic Urologists.

Background: The preoperative lymph node (LN) staging of bladder cancer (BCa) addresses the subsequent therapeutic strategy and influences patient's prognosis. However, sparce evidence exists regarding the accuracy of conventional cross-sectional imaging, such as computed tomography or magnetic resonance imaging, in correctly detect LN status. We aimed to assess the diagnostic accuracy of conventional cross-sectional imaging in detecting preoperative LN involvement among BCa patients treated with radical cystectomy and pelvic lymph node dissection.

Variant histologies in bladder cancer: Does the centre have an impact in detection accuracy?

Objective: To compare the accuracy in detecting variant histologies (VH) at transurethral resection of bladder (TURB) and radical cystectomy (RC) specimen among tertiary referral centres, in order to investigate potential reasons of discrepancies from the pathological point of view.

Patients And Methods: Clinical and histopathological data of TURB specimen and subsequent cystectomy specimen of 3,445 RC candidate patients have been retrospectively collected from 24 tertiary referral centres between 1980 and 2021. VH considered in the analysis were pure squamous cell carcinoma, urothelial carcinoma with squamous differentiation, pure adenocarcinoma, urothelial carcinoma with glandular differentiation, micropapillary bladder cancer (BCa), neuroendocrine BCa, and other variants.

Purpose: To test the impact of carboplatin-based ACT on overall survival (OS) in patients with pN1-3 cM0 BCa.

Methods: A retrospective analysis was conducted on 1057 patients with pTany pN1-3 cM0 urothelial BCa treated with or without carboplatin-based ACT after radical cystectomy and bilateral lymph-node dissection between 2002 and 2018 at 12 European and North-American hospitals. No patient received neoadjuvant chemotherapy or radiation therapy.

Restaging transurethral resection in ta high-grade nonmuscle invasive bladder cancer: a systematic review.

Purpose Of Review: The role of a re-transurethral resection (TUR) is clearly demonstrated in T1 high-grade nonmuscle invasive bladder cancer. However, its role remains controversial for Ta high-risk tumors and the recent European guidelines stated that the second look procedure could be avoided for these patients despite harboring a high-risk of both disease recurrence and progression. We aimed to evaluate the added benefit on staging, response to bacillus Calmette-Guérin and oncological outcomes of re-TUR in patients with Ta high-grade nonmuscle invasive bladder cancer.
