Br J Cancer:系统性炎症评分与脑转移瘤患者的生存预后相关

2021-01-28 xiaozeng MedSci原创

脑转移瘤(BMs)作为常见的实体癌,是一种威胁生命的并发症。

脑转移瘤(BMs)作为常见的实体癌,是一种威胁生命的并发症。免疫检查点抑制剂疗法目前已显示出对BM的活性。然而,相比于需要类固醇治疗的神经系统症状患者,无症状BM患者的临床疗效更高。

系统性炎症评分,包括中性粒细胞与淋巴细胞之比(NLR)、白细胞与淋巴细胞之比(LLR)、血小板与淋巴细胞之比(PLR)、单核细胞与淋巴细胞之比(MLR)以及C反应蛋白/白蛋白之比(CRP/Alb)已被证实会影响肿瘤的控制,并最终影响颅外转移癌患者的生存预后。此外,近期发现的系统性炎症标志物,包括治疗前的CRP、NLR和MLR,与基于免疫检查点抑制剂治疗的患者的无进展生存期(PFS)和总体生存期(OS)相关。

系统性炎症评分与颅外疾病状况相关

然而,目前尚无相关研究揭示BM患者队列中系统性炎症评分的预后影响。因此,该研究旨在分析NLR、LLR、PLR、MLR和CRP/Alb等系统性炎症评分与BM患者的生存预后的相关性。

系统性炎症评分与患者的总生存率相关

研究人员从维也纳脑转移登记处收集了1,250名新确诊的脑转移瘤的患者。研究显示,进行性颅外转移癌患者的PLR和CRP/Alb评分较高,而无颅外转移的相关评分则较低。较低的NLR、LLR、PLR、MLR和CRP/Alb对应着患者更长的总生存期(OS)。而在具有分级预后评估的多变量分析中,NLR、LLR、PLR、MLR和CRP/Alb仍然是与BM诊断时与OS相关的独立因素。


总而言之,该研究结果显示,NLR、LLR、PLR、MLR和CRP/Alb等系统性炎症评分与BM患者的OS相关。研究人员也提出了需要进一步探索相关的免疫调节疗法。
