SCI REP:脑胶质瘤患者PD-L1表达的预后意义!

2017-06-26 xing.T MedSci原创

由此可见,在胶质瘤或GBM患者中,PD-L1可能是一个有前途的预测疾病进展的生物标记物。然而,由于样本量有限,还需要进行进一步的前瞻性或回顾性多中心、精心设计的研究来验证这一结果。

大量的研究表明程序性死亡配体1(PD-L1)在人脑胶质瘤中表达异常。然而,在神经胶质瘤患者中PD-L1的预后意义仍未明确。近日,Scientific reports 杂志上发表了一篇荟萃分析文章,研究人员进行了一项荟萃分析以确定脑胶质瘤患者高表达PD-L1的预后价值。

研究人员对电子数据库进行了检索,找出评估PD-L1表达与脑胶质瘤患者总生存率(OS)的研究。

研究人员共纳入6项研究(发表在4篇文献中),其中包括1052名患者。合并的结果表明较高的PD-L1表达与胶质瘤患者较差的OS相关(风险比为1.30,95%可信区间为1.02-1.65,P=0.032)。进一步的亚组分析表明,在胶质母细胞瘤(GBM)中较高的PD-L1的表达也与较差的OS相关(风险比为1.40,95%可信区间为1.03-1.90,P=0.030)。相反,在指标的亚组分析中,无论是PD-L1蛋白(风险比为1.43,95%可信区间为0.97-2.10,P=0.068)或基因(风险比为1.20,95%可信区间为0.83-1.74,P=0.322)表达均与OS无显著相关性。

由此可见,在胶质瘤或GBM患者中,PD-L1可能是一个有前途的预测疾病进展的生物标记物。然而,由于样本量有限,还需要进行进一步的前瞻性或回顾性多中心、精心设计的研究来验证这一结果。

杜克大学李启靖教授:脑胶质瘤的免疫治疗中,我们要解决哪些问题?

什么是免疫治疗? 在整个肿瘤的发生过程中,都一定会被机体的免疫系统所监视。肿瘤的发展过程中总伴随着细胞的坏死。肿瘤坏死的时候,会释放出抗原。抗原呈递细胞将这些抗原从肿瘤中抓取之后,会回流到淋巴结里,然后被免疫细胞识别。其中,保护人体对抗肿瘤的最重要的免疫细胞就是T细胞。T细胞识别肿瘤抗原、活化以后就会进入血液,会靶向性地透过血管,然后进入肿瘤,在识别肿瘤以后就可以对其进行杀伤。 肿瘤免疫治疗的
