概括
在非小细胞肺癌 (NSCLC) 患者中,添加pemetrexed与bevacizumab显著改善整体存活率和无进展存活率. 然而,这种组合也增加了严重不良事件的风险,表明治疗疗效的权衡.
科学领域:
- 医学瘤学 医学瘤学
- 临床研究 临床研究
- 药理学 药理学是指药理学的学科.
背景情况:
- 非小细胞肺癌 (NSCLC) 仍然是全球癌症死亡的主要原因.
- 贝瓦西祖马布是一种抗血管原剂,用于NSCLC治疗,但其疗效可以提高.
- 化疗剂佩米特雷克塞德 (Pemetrexed) 在与其他疗法结合使用时显示出潜在的潜力.
研究的目的:
- 评估添加佩米特雷克塞德与贝瓦齐祖马布对NSCLC患者治疗疗效的影响.
- 对调查这种组合治疗的随机对照试验 (RCT) 进行元分析.
主要方法:
- 在主要数据库中进行系统的文献搜索:PubMed,EMbase,科学网,EBSCO和Cochrane图书馆.

Combination Therapies and Personalized Medicine
4.9K
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.
