BACKGROUND
Glioblastoma multiforme (GBM), a common primary malignant brain tumor, rarely disseminates beyond the central nervous system and has a very bad prognosis. The current study aimed at the analysis of immunological control in individual patients with GBM.
METHODS
Immune phenotypes and plasma biomarkers of GBM patients were determined at the time of diagnosis using flow cytometry and ELISA, respectively.
RESULTS
Using descriptive statistics, we found that immune anomalies were distinct in individual patients. Defined marker profiles proved highly relevant for survival. A remarkable relation between activated NK cells and improved survival in GBM patients was in contrast to increased CD39 and IL-10 in patients with a detrimental course and very short survival. Recursive partitioning analysis (RPA) and Cox proportional hazards models substantiated the relevance of absolute numbers of CD8 cells and low numbers of CD39 cells for better survival.
CONCLUSIONS
Defined alterations of the immune system may guide the course of disease in patients with GBM and may be prognostically valuable for longitudinal studies or can be applied for immune intervention.
背景
多形性胶质母细胞瘤（GBM）是一种常见的原发性恶性脑肿瘤，很少扩散至中枢神经系统以外，预后很差。本研究旨在分析GBM个体患者的免疫调控情况。
方法
分别在诊断时使用流式细胞术和酶联免疫吸附测定法确定GBM患者的免疫表型和血浆生物标志物。
结果
通过描述性统计，我们发现个体患者存在明显的免疫异常。特定的标志物谱对生存具有高度相关性。GBM患者中活化自然杀伤细胞与生存改善之间的显著关系，与病情恶化且生存期很短的患者中CD39和白细胞介素-10增加形成对比。递归分割分析（RPA）和Cox比例风险模型证实了CD8细胞绝对数量和低数量CD39细胞与更好生存的相关性。
结论
免疫系统的特定改变可能指导GBM患者的疾病进程，对于纵向研究可能具有预后价值，或者可用于免疫干预。
