Background and Objective: Bacillus Calmette-Guérin (BCG) reduces disease recurrence and progression in intermediate- and high-risk non-muscle-invasive bladder cancer (NMIBC). BCG-associated adverse events during instillations are common, leading to treatment cessation. Prophylactic use of quinolones in conjunction with BCG instillations is one approach for reducing BCG-associated adverse events. Our aim was to delineate the clinical impact of quinolone prophylaxis (QP) in patients receiving adjuvant BCG instillations for NMIBC., Methods: In October 2024, a systematic search of MEDLINE, Embase, and the Cochrane Central Register of controlled trials was performed. Prospective and retrospective studies reporting comparative outcomes for patients with and without QP during BCG instillations were included. Outcomes were reported in a binary fashion. Random-effects meta-analysis using the weighted mean difference was conducted. Primary outcomes for pooled analyses included BCG-associated toxicities, the completion rate for BCG induction, the likelihood of antituberculosis treatment, and disease recurrence and progression at 12 mo., Key Findings and Limitations: The systematic review included five studies. Four randomised controlled trials were included in the meta-analysis, and one nonrandomised study was also included in the narrative review. The studies involved 445 patients, of whom 194 received QP + BCG and 251 received BCG alone. QP use was associated with lower incidence of class ≥2 (40.8% vs 54.7%; relative risk [RR] 0.79, 95% confidence interval [CI] 0.67-0.94; p = 0.006), and class ≥3 BCG-associated toxicities (25.3% vs 36.4%; RR 0.70, 95% CI 0.50-0.98; p = 0.04) and a higher completion rate for BCG induction (83.0% vs 70.6%; RR 1.16, 95% CI 1.01-1.34; p = 0.04). The 12-mo recurrence rates (14.7% vs 19.4%; RR 0.76, 95% CI 0.46-1.27; p = 0.3) and progression rates (4.5% vs 6.4%; RR 0.86, 95% CI 0.09-8.25; p = 0.9) did not significantly differ for QP + BCG versus BCG alone., Conclusions and Clinical Implications: The use of QP with adjuvant BCG for NMIBC mitigated debilitating BCG-associated toxicities and improved the completion rate for BCG induction therapy., (Copyright © 2025 European Association of Urology.

Background and Objective: This publication represents a summary of the updated 2024 European Association of Urology (EAU) guidelines for non-muscle-invasive bladder cancer (NMIBC), TaT1, and carcinoma in situ. The information presented herein is limited to urothelial carcinoma, unless specified otherwise. The aim is to provide practical recommendations on the clinical management of NMIBC with a focus on clinical presentation., Methods: For the 2024 guidelines on NMIBC, new and relevant evidence was identified, collated, and appraised via a structured assessment of the literature. Databases searched included Medline, EMBASE, and the Cochrane Libraries. Recommendations within the guidelines were developed by the panel to prioritise clinically important care decisions. The strength of each recommendation was determined according to a balance between desirable and undesirable consequences of alternative management strategies, the quality of the evidence (including the certainty of estimates), and the nature and variability of patient values and preferences., Key Findings and Limitations: Key recommendations emphasise the importance of thorough diagnosis, treatment, and follow-up for patients with NMIBC. The guidelines stress the importance of defining patients' risk stratification and treating them appropriately., Conclusions and Clinical Implications: This overview of the 2024 EAU guidelines offers valuable insights into risk factors, diagnosis, classification, prognostic factors, treatment, and follow-up of NMIBC. These guidelines are designed for effective integration into clinical practice., (Copyright © 2024 European Association of Urology. All rights reserved.)

Context: The European Association of Urology (EAU) guidelines panel on upper urinary tract urothelial carcinoma (UTUC) has updated the guidelines to aid clinicians in evidence-based management of UTUC., Objective: To provide an overview of the EAU guidelines on UTUC as an aid to clinicians., Evidence Acquisition: The recommendations provided in these guidelines are based on a review of the literature via a systematic search of the PubMed, Ovid, EMBASE, and Cochrane databases. Data were searched using the following keywords: urinary tract cancer, urothelial carcinomas, renal pelvis, ureter, bladder cancer, chemotherapy, ureteroscopy, nephroureterectomy, neoplasm, (neo)adjuvant treatment, instillation, recurrence, risk factors, metastatic, immunotherapy, and survival. The results were assessed by a panel of experts., Evidence Synthesis: Even though data are accruing, for many areas there is still insufficient high-level evidence to provide strong recommendations. Patient stratification on the basis of histology and clinical examination (including imaging) and assessment of patients at risk of Lynch syndrome will aid management. Kidney-sparing management should be offered as a primary treatment option to patients with low-risk UTUC and two functional kidneys. In particular, for patients with high-risk or metastatic UTUC, new treatment options have become available. In high-risk UTUC, platinum-based chemotherapy after radical nephroureterectomy, and adjuvant nivolumab for unfit or patients who decline chemotherapy, are options. For metastatic disease, gemcitabine/carboplatin chemotherapy is recommended as first-line treatment for cisplatin-ineligible patients. Patients with PD-1/PD-L1-positive tumours should be offered a checkpoint inhibitor (pembrolizumab or atezolizumab)., Conclusions: These guidelines contain information on the management of individual patients according to the current best evidence. Urologists should take into account the specific clinical characteristics of each patient when determining the optimal treatment regimen according to the risk stratification of these tumours., Patient Summary: Cancer of the upper urinary tract is rare, but because 60% of these tumours are invasive at diagnosis, timely and appropriate diagnosis is most important. A number of known risk factors exist., (Copyright © 2023 European Association of Urology. Published by Elsevier B.V. All rights reserved.)
