概括

这项研究表明,大多数质瘤缺乏足够的向抗原,阻碍了治疗. 复发涉及瘤免疫空间转移,N-糖化分类等级和免疫转录组预测存活率.

科学领域:

神经瘤学神经瘤学
癌症免疫学癌症免疫学
蛋白质组学和葡萄糖组学

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) 和治疗逃逸机制对于开发有效的治疗方法至关重要.

研究的目的:

研究质瘤瘤微环境 (TME) 的空间景观,并确定治疗逃避的标志.
探索潜在的治疗点和生物标志物用于质瘤分类和结果预测.

主要方法:

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...
