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.

Conclusions and clinical implications

The IBCG consensus recommendations provide practical guidance on BPTs for MIBC.
肌肉浸润性膀胱癌的膀胱保存策略:来自国际膀胱癌小组的建议
背景和目的以患者为中心的管理需要提供符合患者价值观、偏好和表达需求的护理。因此,迫切需要对膀胱保留疗法(BPTs)作为肌肉浸润性膀胱癌(MIBC)根治性膀胱切除术(RC)的替代方案进行批判性评估,并就BPTs患者的最佳选择提出实用建议。方法召集全球膀胱癌专家委员会,制定BPT治疗MIBC的建议。工作组审查了文献并起草了建议,这些建议由国际膀胱癌小组(IBCG)成员使用改进的德尔菲程序进行投票。在2023年8月的现场会议上,提交了投票结果和支持证据,并根据讨论完善了建议。最终建议在会议期间达成了≥75%的共识,并通过网络会议和电子邮件讨论进一步完善。新诊断的MIBC患者应在多学科背景下进行评估,以考虑BPTs。RC的主要替代方案是三模式治疗(TMT), TMT的良好预后因素包括单灶性cT2期,无肾积水,无多灶原位癌(CIS)。其他的选择应该保留给那些不符合条件或在充分考虑了获益与风险后拒绝接受TMT或RC的患者。这些包括部分膀胱切除术(PC)治疗尿管腺癌和PC或根治性经尿道切除单独的肿瘤适合切除足够的边缘,没有合并CIS或组织学亚型。结论和临床意义IBCG共识建议为MIBC患者的BPTs提供了实用指导。
