Abstract
Background and objective Patient-centric management necessitates providing care aligned with patients’ values, preferences, and expressed needs. Therefore, critical assessment of bladder preservation therapies (BPTs) as alternatives to radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC) and practical recommendations on the optimal selection of patients for BPTs are needed urgently. Methods A global committee of bladder cancer experts was assembled to develop BPT recommendations for MIBC. Working groups reviewed the literature and drafted recommendations, which were voted on by International Bladder Cancer Group (IBCG) members using a modified Delphi process. During a live meeting in August 2023, voting results and supporting evidence were presented, and recommendations were refined based on discussions. Final recommendations achieved ≥75% agreement during the meeting, with further refinements through web conferences and e-mail discussions. Key findings and limitations Patients with newly diagnosed MIBC should be offered evaluation in a multidisciplinary setting for consideration of BPTs. The main alternative to RC is trimodal therapy (TMT), and favorable prognostic factors for TMT include unifocal cT2 stage, lack of hydronephrosis, and no multifocal carcinoma in situ (CIS). Other options should be reserved for very select patients who are ineligible for or who decline TMT or RC after thorough consideration of benefits versus risks. These include partial cystectomy (PC) for urachal adenocarcinoma and PC or radical transurethral resection alone for solitary tumors amenable to resection with adequate margins and without concomitant CIS or histologic subtypes.
