概括
威尼托克拉克斯加上低甲基化剂在急性髓性白血病 (AML) 患者中显示出有前途的结果,这些患者不符合强化化疗的条件. 在这项现实研究中,AML类型和并发症等因素对整体存活率产生重大影响.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 临床研究 临床研究
背景情况:
- 威尼托克拉克斯加上低甲基化剂是密集化疗不合格的急性髓性白血病 (AML) 的标准.
- 现实世界的数据对于了解临床试验之外的治疗模式和结果至关重要.
- 这项研究提供了对AML多样化的患者群体的见解.
研究的目的:
- 评估venetoclax加上低甲基化剂在新诊断的,不能接受密集化疗的AML患者中的实际结果.
- 在这个患者队列中确定与整体存活 (OS) 相关的因素.
- 根据VIALE-A试验的资格来比较结果.
主要方法:
- 对209名新诊断的,不能接受密集化疗的AML患者进行前性,观察性,多中心研究.
- 随访时间中位数为22.5个月.
- 分析整体存活率,复合完全缓解,以及影响结果的因素,包括AML发育,功能,查尔森并发症指数 (CCI),欧洲白血病NET (ELN) 风险和体重指数.
主要成果:
- 平均整体存活时间 (mOS) 为11.7个月.
- 在65.2%的患者中实现了复合完全缓解 (CR).
- 符合VIALE-A资格标准的患者的mOS时间较长 (17.8个月) 与不符合标准的患者 (10.7个月) 相比.
- AML的发育,功能下降,CCI,ELN风险和BMI与OS有显著的关联.
- 在研究期间晚些时候注册的患者中观察到改善的OS.
结论:
- 威尼托克拉克斯加上低甲基化剂在现实世界,密集化疗不合格的AML患者群体中显示出显著的疗效.
- 患者的特征,如AML本体发生,并发症 (CCI) 和疾病风险 (ELN) 是生存的关键决定因素.
- 现实世界的数据捕捉了经常被排除在临床试验之外的子组的结果,为治疗策略提供了信息.

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...
