结合T细胞炎症和免疫变异特征的新生物标志物改善了在非小细胞肺癌 (NSCLC) 中对抗编程细胞死亡蛋白1 (PD-1) 治疗反应的预测. 这种方法为免疫治疗提供了更好的患者分层.
科学领域:
- 免疫学 免疫学 免疫学
- 在瘤学瘤学.
- 基因组学就是基因组学.
背景情况:
- 抗PD-1/PD-L1疗法为高级非小细胞肺癌 (NSCLC) 提供了革命性的治疗方法.
- 对这些疗法的响应率很低,这凸显了对预测生物标志物的需求.
- 以前建立的T细胞炎症基因表达特征 (GEP) 无法预测大型NSCLC队列中的抗PD-1反应.
研究的目的:
- 开发和验证用于NSCLC的抗PD-1/PD-L1治疗的新型预测生物标志物.
- 研究骨髓状细胞和树突细胞基因特征在预测治疗反应中的作用.
- 探索对影响免疫疗法疗效的免疫变化的机制性见解.
主要方法:
- 重新分析了Stand Up To Cancer-Mark (SU2C-MARK) 基金会NSCLC队列的研究结果.
- 使用机器学习开发一种组合生物标志物,将T细胞炎症的GEP与免疫改变的签名集成在一起.
- 在六个独立的癌症队列中,用抗PD-1疗法治疗的联合生物标志物的验证.
主要成果:
- 单独T细胞炎症的GEP对NSCLC没有预测作用.
- 将T细胞炎症的GEP与髓质细胞基因特征结合起来,显著改善了预测性能.
- 新型组合生物标志物在NSCLC和胃癌队列中表现出增强的预测能力,但在黑色素瘤队列中没有.
结论:

Tumor Immunotherapy
475
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.

Combination Therapies and Personalized Medicine
4.8K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
