概括
实现无治疗缓解 (TFR) 是可能的,因为许多患者停止了氨酸激酶抑制剂 (TKI) 治疗. BCR::ABL1数字PCR准确地预测了TFR的成功,特别是在较长的TKI治疗持续时间.
科学领域:
- 血液学 血液学 血液学
- 分子诊断学 分子诊断学
- 在瘤学瘤学.
背景情况:
- 大约40%-60%的患者在停止氨酸激酶抑制剂 (TKI) 治疗后实现无治疗缓解 (TFR).
- 通过BCR::ABL1数字PCR测量的深度分子反应是成功TFR的关键预测因子.
研究的目的:
- 评估BCR::ABL1数字PCR作为荷兰的TFR预测工具.
- 评估BCR::ABL1数字PCR的预测值,用于在0.0023%IS截止值以下的TKI停止.
主要方法:
- 在67名在BCR::ABL1数字PCR截止值以下停止TKI治疗的患者中,对12个月后分子复发 (MolR) 的前性评估.
- 基于TKI治疗持续时间 (≥6年 vs <6年) 的MolR率分析.
主要成果:
- 总的来说,MolR概率为50%.
- 与接受治疗6年或更长时间的患者 (76%) 相比,接受治疗6年或更长时间的患者 (36%) 的MolR概率较低.
- 在荷兰临床实践中,BCR::ABL1数字PCR成功预测了TFR.
结论:
- 六年或更长的TKI治疗持续时间与较低的MolR率和更高的TFR成功率有关.
- BCR::ABL1数字PCR是一种有价值的工具,用于识别具有更高TFR成功概率的TKI停止候选人.

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.
