概括
与瘤相关的免疫抑制会影响癌症治疗的有效性. 高中性粒细胞与淋巴细胞比率 (NLR) 是质母细胞瘤预后不良的因素,这促使人们呼吁在神经瘤学研究中进行动态免疫标志物评估.
科学领域:
- 神经瘤学神经瘤学
- 免疫学 免疫学 免疫学
- 癌症治疗 癌症治疗
背景情况:
- 瘤治疗的有效性取决于宿主免疫细胞的活性,但癌症患者经常表现出局部和全身免疫抑制.
- 与质母细胞瘤相关的免疫抑制包括淋巴衰竭,免疫抑制细胞子集的增加 (例如,髓质母细胞衍生的抑制细胞,调节性T细胞) 和免疫细胞功能受损.
- 免疫细胞格局和预后意义在质瘤分子亚型 (IDH突变,神经前,古典,介质细胞) 上有所不同.
研究的目的:
- 在标准化疗或放射治疗之前,在基线检查与质母细胞瘤相关的免疫抑制.
- 讨论各种循环和瘤透免疫细胞在质母细胞瘤的预后意义.
- 突出显示大脑中的免疫监测特征以及识别可靠的预后免疫标记物的挑战.
主要方法:
- 对现有数据的审查,重点关注化学放射治疗前的质母细胞瘤/质瘤患者.
- 分析免疫细胞子集的预后意义,包括淋巴细胞,T细胞 (CD4 +,CD8 +),NK细胞,中性粒细胞,巨细胞,MDSCs,树突细胞和中性粒细胞与淋巴细胞的比率 (NLR).
- 检查IDH突变质瘤和分子亚型中的免疫景观,以及大脑免疫监测.
主要成果:
- 在质母细胞瘤组织中识别可靠的预后免疫标志物是具有挑战性的,因为免疫入的异质性和免疫亚群的多样性.
- 高的NLR是一个持续证实的独立预后因素,用于缩短质母细胞瘤和癌症的整体存活时间.
- 将NLR与其他免疫反应或炎症标志物的结合可能会提高预测的准确性,但需要进一步的前性验证.
结论:
- 在神经瘤学研究中,对NLR和其他血液炎症标志物的动态评估 (例如,淋巴细胞计数,PLR,LMR,SII,SIRI) 是至关重要的.
- 需要对这些标志物的个人和组合预后/预测意义进行严格的评估.
- 需要进一步的前性研究来确认NLR和相关炎症标志物的预后和预测能力.

The Tumor Microenvironment
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
