The current treatment paradigm for muscle-invasive bladder cancer (MIBC) consists of cisplatin-based neoadjuvant chemotherapy followed by local definitive therapy, or local definitive therapy alone for cisplatin-ineligible patients. Given that MIBC has a high propensity for distant relapse and is a chemotherapy-sensitive disease, under-utilization of chemotherapy is associated with suboptimal cure rates. Cisplatin eligibility criteria are defined for patients with metastatic bladder cancer by the Galsky criteria, which include creatinine clearance ≥60 ml/min. However, consensus is still lacking regarding cisplatin eligibility criteria in the neoadjuvant, curative MIBC setting, which continues to represent a substantial barrier to the standardization of patient care and clinical trial design. Jiang and colleagues accordingly suggest an algorithm for assessing cisplatin eligibility in patients with MIBC. Instead of relying on an absolute renal function threshold, their algorithm emphasizes a multidisciplinary and patient-centred approach. They also propose mitigation strategies to minimize the risk of cisplatin-induced nephrotoxicity in selected patients with impaired renal function. This new framework is aimed at reducing the inappropriate exclusion of some patients from cisplatin-based neoadjuvant chemotherapy (which leads to under-treatment) and harmonizing clinical trial design, which could lead to improved overall outcomes in patients with MIBC.
目前肌层浸润性膀胱癌(MIBC)的治疗模式包括顺铂为基础的新辅助化疗,随后进行局部确定性治疗,或不适合顺铂的患者仅进行局部确定性治疗。鉴于 MIBC 有远处复发的高倾向,且对化疗敏感,化疗的利用不足与较差的治愈率有关。Galsky 标准为转移性膀胱癌患者定义了顺铂的适应证,包括肌酐清除率≥60ml/min。然而,在新辅助治疗、根治性 MIBC 环境中,顺铂的适应证标准仍缺乏共识,这仍然是患者护理和临床试验设计标准化的一个重要障碍。蒋及其同事因此提出了一种用于评估 MIBC 患者顺铂适应证的算法。他们的算法不依赖于绝对肾功能阈值,而是强调多学科和以患者为中心的方法。他们还提出了减轻策略,以最小化选定肾功能受损患者中顺铂引起的肾毒性的风险。这个新框架旨在减少一些患者因接受顺铂为基础的新辅助化疗而被不当排除(导致治疗不足),并协调临床试验设计,这可能会改善 MIBC 患者的总体预后。
