概括
KRAS突变与接受免疫检查点抑制剂 (ICI) 的高级非小细胞肺癌 (NSCLC) 患者的更好的结果有关. 这一元分析证实了KRAS突变是改善NSCLC总体存活率和无进展存活率的积极预测生物标志物.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 遗传学 遗传学 是一个
背景情况:
- 免疫检查点抑制剂 (ICI) 已经改变了癌症治疗.
- KRAS突变在非小细胞肺癌 (NSCLC) 中很常见,可能会影响瘤免疫性.
- 对于ICI疗效的KRAS突变的预测作用需要进一步澄清.
研究的目的:
- 进行对KRAS突变进行评估的元分析,以此作为ICI治疗的晚期NSCLC患者生存结果的预测生物标志物.
- 巩固KRAS突变与免疫检查点抑制剂治疗反应之间的相关性证据.
主要方法:
- 在PubMed,Web of Science和Scopus数据库中进行了系统的文献搜索,直到2022年5月.
- 分析了10项符合条件的研究数据,总共有8722个选的标题/摘要.
- 总生存率 (OS) 和无进展生存率 (PFS) 用聚合危险比率 (HRs) 进行评估.
主要成果:
- 在接受ICI治疗的NSCLC患者中,KRAS突变与显著改善的OS相关 (HR = 0.89,95% CI: 0.79-0.99).
- 在这个患者队列中,KRAS突变也预测了显著更好的PFS (HR = 0.72,95%CI:0.59-0.87).
- 使用科克兰Q测试和I2统计学来评估异质性.
结论:
- 在接受免疫检查点抑制剂单一治疗的晚期NSCLC患者中,KRAS突变可能作为积极的预测生物标志物.
- 这些发现支持对KRAS突变状态的调查,以指导NSCLC的治疗决策.
- 需要进一步的研究来阐明这种关联背后的机制.

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.

Combination Therapies and Personalized Medicine

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...
