概括
非小细胞肺癌 (NSCLC) 的骨转移 (BoM) 对免疫检查点抑制剂 (ICI) 的反应不佳. 波马的存在独立地预测了更糟糕的整体存活率,表明需要额外的治疗方法.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 放射学 放射学是一门学科.
背景情况:
- 骨转移 (BoM) 在非小细胞肺癌 (NSCLC) 中很常见.
- 关于BOM对免疫检查点抑制剂 (ICI) 的反应的数据有限.
- 了解BoM对ICI的反应对于治疗优化至关重要.
研究的目的:
- 为了比较BoM对ICI的成像反应与内脏转移.
- 评估BoM对ICI治疗的NSCLC患者整体生存时间的影响.
主要方法:
- 对接受尼沃卢马布或布罗利祖马布治疗的NSCLC患者进行了回顾性多中心队列研究 (2015-2020年).
- 主要终点:骨与内脏转移的器官特异性无进展生存率 (osPFS).
- 二级终点:患有和没有BOM的患者的整体存活率 (OS).
主要成果:
- 骨,肝脏和腹内转移之间的osPFS没有显著差异.
- 博姆斯对ICI的内脏疾病反应显示出显著的不一致 (p=0.047).
- 波马是OS (HR 1.26,p=0.01) 的一个独立的不良预后因素.
结论:
- 转移的骨,肝脏和腹内病变对ICI的反应较差.
- 瘤和肝转移是OS的独立不良预后因素.
- 博姆对ICI反应不佳,可能需要治疗辅助剂以更好地控制疾病.

Tumor Immunotherapy
509
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.
