概括
将辅助免疫检查点抑制剂 (ICI) 治疗添加到新辅助化学免疫疗法并没有改善可切除非小细胞肺癌 (NSCLC) 的存活率. 需要进一步的研究,以优化NSCLC患者的外科手术期间ICI策略.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 临床试验 临床试验
背景情况:
- 免疫检查点抑制剂 (ICI) 改善了可切除非小细胞肺癌 (NSCLC) 的结果.
- 目前正在评估各种外科手术期间的ICI策略,但最佳方法尚不清楚.
研究的目的:
- 系统地审查和元分析随机对照试验 (RCT),评估可切除NSCLC的术后治疗方法.
- 确定不同外科手术期间免疫检查点抑制剂 (ICI) 策略的有效性和安全性.
主要方法:
- 对RCT进行系统审查,比较可切除NSCLC的术后治疗方法.
- 随机模型网络对11个涉及4,532名患者的RCT进行了元分析.
- 七种不同的周围手术策略的比较.
主要成果:
- 将辅助性ICI添加到新辅助性化疗免疫疗法并没有显著改善无事件生存 (EFS) 或整体生存 (OS).
- 仅使用辅助剂的化学免疫疗法和外科手术期间的化学免疫疗法在数值上显示了比仅使用辅助剂更长的生存期,但没有统计学意义.
- 将ICI添加到新辅助化学免疫治疗中没有增加与治疗相关的不良事件 (TRAE) 的发生率.
结论:
- 没有明显的生存益处被观察到添加辅助性ICI治疗新辅助性化疗免疫治疗可切除的NSCLC.
- 需要进一步的研究来比较仅使用新辅助剂与外科手术期间的化疗免疫疗法.
- 对可切除NSCLC的最佳ICI治疗持续时间和周期需要进一步调查.

Tumor Immunotherapy
664
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.
