概括
在全源造血干细胞移植 (HSCT) 后,索拉费尼布 (SORA) 的维护显著降低了FLT3突变AML患者的复发率. 这种FLT-3抑制剂疗法改善了整体存活率和无复发存活率,提供了一个重要的复发预防策略.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 药理学 药理学是指药理学的学科.
背景情况:
- 在全源造血干细胞移植 (HSCT) 后复发影响了近50%的FLT3-ITDAML患者.
- FLT-3 抑制剂 (FLT3i) 显示出后HSCT复发预防的前景.
研究的目的:
- 评估Sorafenib (SORA) 维持治疗在预防FLT3突变AML患者在HSCT后复发中的疗效.
- 为了比较FLT3突变AML患者在HSCT后接受SORA与未接受SORA的患者之间的结果.
主要方法:
- 追溯比较24名FLT3突变AML患者的HSCT后SORA与24名无SORA对照.
- 移植后平均2.9个月开始SORA,平均剂量为每天600毫克,持续8.8个月.
- 由于毒性,在16/24名患者中注意到剂量修改和早期退出.
主要成果:
- 与对照组 (9次复发) 相比,SORA组的复发率明显较低 (1次复发) (p=0.004).
- 在SORA组中改善了整体存活率 (OS) 和无复发存活率 (RFS) (OS为36.3个月,RFS为11.6个月,p=0.01;RFS为95.5%和66.7%,p=0.004).
- 在完全缓解和可检测的MRD (p=0.001) 的患者中,SORA的维持降低了93.6%的死亡风险,死亡率仅为4.2%,而对照组的50% (p<0.001).
结论:
- 在HSCT后的索拉芬尼维护显著降低了FLT3突变AML的复发发病率.
- 索拉治疗延长了OS和RFS,使其成为HSCT后有效的复发预防策略.

Combination Therapies and Personalized Medicine
5.1K
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.
