概括

这项研究表明,大多数质瘤表达的向抗原很少,阻碍了治疗. 复发涉及瘤微环境 (TME) 的变化,N-糖化预测等级和免疫标志物预测存活率.

科学领域:

神经瘤学神经瘤学
癌症生物学癌症生物学
免疫学免疫学免疫学

背景情况:

质瘤是具有不良预后和有限治疗策略的侵袭性脑瘤.
了解瘤微环境 (TME) 演变和治疗逃生机制对于改善患者的治疗结果至关重要.

研究的目的:

研究质瘤中治疗逃避和TME演变的特征.
为了确定新的治疗点和预测生物标志物,用于质瘤分类和生存.

主要方法:

空间蛋白质组学,转录组学和糖组学应用于来自310名患者的670个质瘤病变.
进行了单细胞和多原子整合分析,以表征瘤异质性和TME组成.

主要成果:

在质母细胞瘤 (GBM) 和多形黄细胞瘤 (PXA) 中观察到高的B7H3+瘤细胞患病率.
大多数质瘤在不到50%的瘤细胞中表达向抗原,这可能解释治疗失败.
IDH突变性质瘤的复发与TME重组有关,免疫细胞群体的变化.
N-糖化最好地分类了质瘤等级,而免疫转录组预测了GBM存活率.

结论:

这项研究提供了质瘤TME的全面的多原子地图,为治疗耐药性提供了洞察力.
确定可向抗原和预测生物标志物可以指导未来的质瘤治疗策略,并改善患者分层.
这些发现为所有质瘤阶段的TME组成建立了基线,促进了进一步的研究和临床应用.

Tumor Progression

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
