Unlabelled: Inflammation is widely acknowledged as a significant characteristic of cancer, playing a substantial function in both the initiation and advancement of cancers. In this research, we planned to compare pan-immune inflammation markers and other well-known markers (systemic immune inflammation index and neutrophil to lymphocyte ratio) to predict prognosis in individuals treated with radical cystectomy for bladder cancer.
Methods: In this retrospective analysis, we focused on preoperative PIV, systemic immune inflammation index (SII), and neutrophil-lymphocyte ratio (NLR) in 193 individuals managed with radical cystectomy for bladder cancer between January 2016 and November 2022. Multivariable logistic regression assessments were performed to assess the predictive capabilities of PIV, SII, and NLR for infiltration of lymph nodes (N), aggressive tumor stage (pT3/pT4), and any non-organ limited disease at the time of RC. Multivariable Cox regression analyses were conducted to assess the predictive impact of PIV on Relapse-free survival (RFS), Cancer-specific survival (CSS), and Overall survival (OS).
Results: Our individuals were divided into high PIV and low PIV cohorts using the optimal cut-off value (340.96 × 10/L) based on receiver operating characteristic curve analysis for relapse-free survival. In multivariable preoperative logistic regression models, only SII and PIV correlated with the infiltration of lymph nodes, aggressive disease, and any non-organ confined disease. In multivariable Cox regression models considering presurgical clinicopathological variables, a higher PIV was associated with diminished RFS ( = 0.017) and OS ( = 0.029). In addition, in multivariable Cox regression models for postoperative outcomes, a high PIV correlated with both RFS ( = 0.034) and OS ( = 0.048).
Conclusions: Our study suggests that PIV and SII are two very similar markers that may serve as independent and significant predictors of aggressive disease and worse survival impacts on individuals undergoing radical cystectomy for bladder neoplasm.

Background And Objective: There is an established association between secondary bladder cancers (SBCs) and radiotherapy (RT) for prostate cancer (PC), which remains a significant concern. Our aim was to update the evidence on SBC incidence across different RT modalities and to compare oncological outcomes for patients diagnosed with SBC to those diagnosed with primary bladder cancer (PBC).
Methods: We searched MEDLINE, Scopus, and Web of Science for studies on SBC following PC.

Purpose: To investigate the association of diabetes mellitus and metformin use with metabolic acidosis risk after radical cystectomy (RC) and urinary diversion for bladder cancer.
Materials And Methods: This retrospective cohort study used TriNetX Research Network data. Patients undergoing RC with continent diversion or ileal conduit for bladder cancer were identified using International Classification of Diseases, 10th Revision (ICD-10) and ICD-10 Procedure Coding System (ICD-10-PCS) codes.
Background: Radical cystectomy has the potential to be a curative strategy for patients with aggressive bladder cancer. Emerging evidence over the last 20 years has shown that minimally invasive surgical approaches using robotics in performing this highly complex and morbid operation can achieve the same oncological outcomes while reducing complications for the patient.
Objective: This paper aims to present a managerial and leadership roadmap for change to robotic cystectomy for patients with advanced bladder cancer to achieve improved patient outcomes while embracing technological developments in the delivery of cancer care.

Purpose: Prehabilitation in patients with bladder cancer recommended for cystectomy has the potential to improve functional status and outcomes after cystectomy. Prior research has shown that increasing exercise preoperatively can improve strength and quality of life, but research has not yet investigated the impact on length of stay, readmissions, complications and mortality.
Methods: We compared historical controls (2021-2022) for patients with bladder cancer who underwent radical cystectomy at a major academic center to those referred for prehabilitation consultation (2023) on postoperative outcomes, namely hospital length of stay, 30 and 90 day readmission rates, postoperative complications and 90-day mortality.

Objective: To assess 30- and 90-day postoperative complication rates in patients who underwent robot-assisted radical cystectomy (RARC) after receiving novel immunotherapy-based neoadjuvant treatment.
Methods: A bi-centre analysis was conducted in patients who underwent RARC with intracorporeal urinary diversion and who received an immunotherapy-based neoadjuvant regimen between 2017 and 2023. Complications were classified using the Clavien-Dindo system.
