一个新的NOTCH评分模型预测了头部和部状细胞癌 (HNSCC) 的生存率. 这种HNSCC预后工具可以识别具有低生存率和免疫抑制瘤微环境的高风险患者,指导个性化治疗.
科学领域:
- 在瘤学瘤学.
- 癌症基因组学 癌症基因组学
- 瘤微环境 瘤微环境
背景情况:
- 头部和部状细胞癌 (HNSCC) 是积极的,结果不佳.
- 在HNSCC中,NOTCH信号通常被禁用,但其预后作用和微环境联系尚不清楚.
研究的目的:
- 开发和验证基于HNSCC.NOTCH相关基因的预后模型.
- 调查预后模型与临床结果,免疫透和治疗反应之间的关联.
主要方法:
- 使用单变Cox回归和差异表达分析识别了NOTCH相关的基因.
- 通过LASSO回归构建了一个预后风险模型 (NOTCH得分).
- 评估了与结果,免疫透和药物敏感性的关联;利用单细胞RNA测序和免疫组织化学.
主要成果:
- 开发了一种基于7基因NOTCH的预后模型 (NOTCH评分),将患者分为高风险和低风险组.
- 高风险HNSCC患者的生存率明显降低,瘤微环境具有免疫抑制作用,与免疫治疗反应不佳相关.
- 该模型表现出强大的预后性能 (AUC > 0.7) 并确定了对特定药物的敏感性;基因主要表达在树皮细胞中.
结论:
- 一个经过验证的NOTCH基础的预后模型 (NOTCH得分) 有效地预测HNSCC患者的结果.
- NOTCH评分有助于评估免疫状态,预测治疗反应和个性化HNSCC治疗.

Notch Signaling Pathway
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...

Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...
Tumor Progression
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...
