概括
前期放射治疗改善了仅接受免疫检查点抑制剂 (ICI) 的高级非小细胞肺癌 (NSCLC) 患者的生存率. 然而,添加放射治疗并没有使ICI和化疗治疗的患者受益.
科学领域:
- 在瘤学瘤学.
- 辐射疗法 辐射疗法
- 免疫治疗是一种免疫疗法.
背景情况:
- 免疫检查点抑制剂 (ICI) 是高级NSCLC的标准.
- 大脑转移 (BMs) 在NSCLC患者中很常见.
研究的目的:
- 为了评估前期放射治疗对NSCLC患者的生存益处,仅用ICI治疗或用化疗治疗.
- 为了比较接受BMs前期放射治疗的患者和没有接受BMs的患者之间的结果.
主要方法:
- 在50所研究所进行的,仅用ICI或ICI化疗治疗的NSCLC患者的回顾性研究.
- 倾向性评分分析 (IPTW和OW) 用于调整混因素.
- 在放射治疗和无放射治疗组之间比较总生存率 (OS).
主要成果:
- 在单独ICI队列 (224名患者) 中,前期放射治疗显著改善了OS (IPTWHR=0.45,OWHR=0.52).
- 在ICI化疗队列 (367名患者) 中,前期放射治疗没有显示OS的显著差异 (IPTWHR=1.02,OWHR=0.93).
结论:
- 对BMs的前期放射治疗有益于仅接受ICI的NSCLC患者.
- 放射治疗似乎没有提供额外的生存益处,当结合ICI和化学治疗NSCLC与BMs.

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.

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.

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.
