AI Article Synopsis
- The study investigates the management of bladder cancer in patients with variant pathology, specifically focusing on micropapillary and nested variants.
- Out of ten patients analyzed, eight had micropapillary carcinoma, with a median age of 75; several experienced lymph node invasion and some had local recurrences despite surgery.
- The findings suggest that aggressive surgical intervention, including radical cystectomy and careful monitoring for urethral involvement, is crucial for patients with these aggressive variants of bladder cancer.
Article Abstract
Purpose: The aim of this study is to report our experience in managing bladder cancer in patients with variant pathology.
Methods: Retrospective data collection for all patients managed by radical cystectomy over the last 3 years for a variant pathol-ogy was completed. We specifically included micropapillary and nested variants.
Results: Ten patients were identified, with eight having micropapillary carcinoma (MPC) and two having nested vari-ants. Nine patients were male. The median age was 75. The two patients with nested variant were 56 and 62 years old, respec-tively, whereas all patients with MPC were over the age of 70. Upon cystectomy of all micropapillary cases, three patients (37.5%) had positive lymph node invasion and the final patholo-gy was T2 (two patients), T3 (two patients), and T4 (four patients). Barring a grade III complication Clavien-Dindo classi-fication due to wound dehiscence that necessitated secondary surgical closure, there were no specific perioperative complica-tions. Given the urethral invasion, cystourethrectomy was per-formed on the female patient. Within a median 13-month fol-low-up, three patients developed local recurrence, including two urethral and one new lateral pelvic mass.
Conclusions: Considering the muscle invasive nature of micropapillary and nested bladder cancer, aggressive surgical management should not be postponed. Moreover, due to notable prevalence of concurrent and/or recurrent urethral involvement, initial urethrectomy or early and frequent postoperative ure-throscopy should be provided. Patients with variant histology bladder cancer may benefit from early radical cystectomy when compared to bladder sparing protocols and prostate sparing cystectomy treatment options.

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.
