- 评估结合多种生物标志物的潜力,以提高预测准确度.
主要成果:
- 编程死亡配体1 (PD-L1) 表达是NSCLC免疫治疗反应的既定但不完美的生物标志物.
- 新兴的生物标志物,如瘤突变负担,瘤微环境,肠道微生物组和T细胞受体谱正在被研究以改善预测.
- 结合多个生物标志物可能比单个标志物更准确地预测免疫疗法的疗效.
结论:
- 目前在晚期NSCLC中用于免疫治疗的预测生物标志物,主要是PD-L1表达,需要加强.
- 新型生物标志物和组合策略在NSCLC免疫疗法中具有显著的潜力,可以优化患者选择和治疗结果.

Tumor Immunotherapy
539
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.

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
