概括
辐射疗法 (RT) 与免疫检查点抑制剂 (ICI) 结合,可以在非小细胞肺癌 (NSCLC) 患者中诱导abscopal反应 (AR). 年龄较大与更高的AR率有关,而更好的ECOG得分和寡头转移性疾病改善了整体存活率.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 辐射瘤学 辐射瘤学
背景情况:
- 放射治疗 (RT) 和免疫检查点抑制剂 (ICI) 显示出协同作用的抗瘤免疫反应.
- 随着RT和ICI治疗的结合,越来越多地观察到非辐射病变回归的abscopal反应 (AR).
- 在接受RT和ICI的非小细胞肺癌 (NSCLC) 患者中了解影响AR的因素至关重要.
研究的目的:
- 分析在接受RT和ICI治疗的NSCLC患者中abscopal反应 (AR) 的频率.
- 为了确定与AR相关的因素,在这个患者队列中,abscopal益处 (AB) 和整体存活率 (OS).
主要方法:
- 一项多中心的回顾性研究 (ARTIC) 分析了56名在ICI治疗期间或之后接受RT治疗的NSCLC患者的疾病进展情况.
- 患者按非辐射损伤反应分类.
- 使用后勤和考克斯回归模型来确定与AR,AB和OS相关的因素.
主要成果:
- 56名患者中有15名 (26.8%) 在至少一个非辐射病变中经历了AR.
- 年龄较大 (OR:1.07) 与AR的发病率较高有关,而男性则呈现增加AR风险的趋势 (OR:3.13).
- 改善的生存状况与更好的ECOG绩效得分 (HR:0.29) 和小卵性转移性疾病 (HR:0.34) 显著相关.
结论:
- 在ICI进展的NSCLC患者中,RT可以诱导AR,这可能会延迟需要进行全身治疗更改的需要.
- 在老年患者和男性中,abscopal (AB) 的益处较少.
- 在这种情况下,ECOG表现状况和寡头转移性疾病是改善存活率的关键预测因素.

Tumor Immunotherapy
2.1K
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.

Treatment Resistant Cancers
3.9K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
