膀胱浸润性尿路上皮癌PD-L1(SP263)免疫组织化学检测病理专家共识

简要介绍:

与非肌层浸润的膀胱尿路上皮癌相比,发生肌层浸润的尿路上皮癌预后较差,出现远处转移后其生存率更低,5年生存率仅为8.1%。传统上肌层浸润性膀胱癌的主要治疗手段是膀胱根治手术与以铂类为主的化疗,但总体疗效差。随着免疫治疗的进展,免疫检查点抑制剂在多种恶性肿瘤中取得了令人瞩目的疗效。目前的研究表明,抑制PD⁃1/PD⁃L1免疫检查点的免疫治疗药物对部分膀胱癌患者有显著疗效,可用于无法耐受铂类化疗的转移性膀胱癌患者的一线药物治疗或经过一线铂类化疗后病情进展患者的二线治疗。研究显示,与PD⁃L1低表达或不表达的患者相比,PD⁃L1高表达患者的免疫治疗效果更好。免疫组织化学染色是检测PD⁃L1表达水平的有效手段,但目前国内对于膀胱尿路上皮癌PD⁃L1(SP263)的免疫组织化学染色判读尚无统一的规范。近日国家药品监督管理局已批准PD⁃L1(SP263)检测作为替雷利珠单抗注射液的伴随诊断检测。为了更好地预测患者对PD⁃L1免疫抑制剂治疗的疗效和指导临床用药,中华医学会病理学分会泌尿与男性生殖系统疾病病理专家组在全国多家大型医院病理科参与的多中心研究基础上,进行了多次针对性的理论及实践操作培训,并召开了数次学组会议进行了广泛而深入的讨论,最终制定了膀胱浸润性尿路上皮癌PD⁃L1(SP263)免疫组织化学检测规范的病理专家共识。
