World J Urol:在尿路上皮癌中,PD-1/PD-L1抑制作用的响应预测因子研究

2018-11-10 AlexYang MedSci原创

转移性尿路上皮癌(mUC)患者的生存情况数据所知甚少。在过去的40年终红,化疗一直都是mUC的主要治疗方法。免疫检查点抑制剂(ICI)的发现,尤其是程序性细胞死亡1抑制剂和它的配体(PD-1/PD-L1)的发现对癌症的免疫治疗起到了革命性的作用。PD-1/PD-L1抑制剂为患有UC患者提供了一种新的和有效的治疗选择,尤其是对那些铂化疗后复发和对铂化疗不敏感的患者。最近,有研究人员利用关键词、医学主

转移性尿路上皮癌(mUC)患者的生存情况数据所知甚少。在过去的40年终红,化疗一直都是mUC的主要治疗方法。免疫检查点抑制剂(ICI)的发现,尤其是程序性细胞死亡1抑制剂和它的配体(PD-1/PD-L1)的发现对癌症的免疫治疗起到了革命性的作用。PD-1/PD-L1抑制剂为患有UC患者提供了一种新的和有效的治疗选择,尤其是对那些铂化疗后复发和对铂化疗不敏感的患者。

最近,有研究人员利用关键词、医学主标题以及移行尿路膀胱癌相关词汇、免疫治疗、免疫检查点抑制和生物标记以及PD-1/PD-L1与在PubMed, ClinicalTrials.gov和年刊大会摘要上进行了文献搜索。研究发现,尽管一些患者阐述了ICI治疗后完整的和/或持续的治疗响应,而对ICI治疗相应可靠的预测仍旧无法实现。在临床背景下,医生还不能够对mUC的ICI治疗响应进行预测,同时也不能选择那些患者将会从ICI治疗中受益。临床试验数据探索性分析阐释了PC-L1的表达、肿瘤变异负担、肿瘤浸润淋巴结和基因表达情况也许在不同的患者群体中具有预测或者预后价值。

最后,研究人员指出,确定有效的生物标记仍旧需要进行开发,从而对UC患者的ICI治疗响应进行预测。
