概括
在高级非小细胞肺癌 (NSCLC) 中监测循环瘤DNA (ctDNA) 表明ctDNA清除或减少与改善的生存率相关. 这一发现支持ctDNA动力学作为接受向治疗或免疫检查点阻塞的患者的有价值的预后标记.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 基因组学就是基因组学.
背景情况:
- 预测晚期非小细胞肺癌 (NSCLC) 的治疗反应仍然是一个临床挑战.
- 循环瘤DNA (ctDNA) 的纵向监测提供了一种非侵入性方法来跟踪瘤动态和治疗疗效.
- 免疫检查点阻塞 (ICB) 和向治疗 (TT) 是高级NSCLC的关键治疗方法,但早期反应预测至关重要.
研究的目的:
- 评估ctDNA清除或减少与晚期NSCLC患者的生存结果之间的关联.
- 评估ctDNA动力学在不同的全身疗法,包括TT和ICB的预后价值.
- 通过元分析合成来自多项研究的证据,以确定ctDNA动力学作为生物标记物的可靠性.
主要方法:
- 进行了2024年4月之前发表的研究的系统审查和元分析.
- 搜索的数据库包括MEDLINE,EMBASE和科克兰图书馆.
- 无进展生存期 (PFS) 和整体生存期 (OS) 的聚合危险比率 (HR) 使用随机效应模型计算.
主要成果:
- 包括32项研究,包括3047名NSCLC患者.
- 在不同疗法中,ctDNA减少/清除与改善的PFS (HR:0.32) 和OS (HR:0.31) 显著相关.
- 在针对性治疗和ICB亚组以及敏感性分析中,无论NSCLC亚型,吸烟状况或性别,益处都是一致的.
结论:
- 血ctDNA动力学作为一个重要的预后指标在先进的NSCLC.
- 在接受TT和ICB治疗的患者中,ctDNA清除或减少与改善生存结果密切相关.
- 纵向ctDNA监测可以帮助预测治疗反应,并指导高级NSCLC的临床管理.

Combination Therapies and Personalized Medicine
4.8K
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.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

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.
