概括
在慢性髓性白血病 (CML) 患者中,将氨酸urea (HU) 添加到 imatinib 治疗并没有显著改善早期分子反应. 需要进一步的研究来探索HUHU.
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:
- 伊马替尼是慢性阶段慢性髓性白血病 (CML-CP) 的标准治疗方法.
- 在CML-CP中,基尿素 (HU),一种DNA合成抑制剂的疗效较少被理解.
- 这项研究比较了结构化剂量HU结合伊马替尼与伊马替尼单一治疗.
研究的目的:
- 在CML患者中,根据基线总白细胞计数 (TLC) 进行结构化剂量基尿素 (HU) 的疗效与伊马替尼布单一治疗进行比较.
- 评估两个治疗臂的早期分子响应 (EMR) 和安全概况.
主要方法:
- 一个开放的随机对照试验,涉及90名新诊断的CML-CP患者.
- 患者接受了与伊马替尼布或伊马替尼布单独治疗的HU治疗3个月.
- 对BCR-ABL1进行定量实时PCR评估EMR;使用CTCAE v5.5评估安全性.
主要成果:
- 在3个月后,74名患者 (36名I-HU,38名伊马替尼单独治疗) 观察到完整的血液学反应.
- 总的来说,68名患者实现了EMR (34名在I-HU中,34名在伊马替尼单疗中;p=0.53).
- 贫血是最常见的血液毒性;恶心和吐是最常见的非血液毒性.
结论:
- 提前添加基于TLC的HU给imaatinib,在3个月后并没有显著改善血液学反应或EMR.
- 需要使用更大的样本大小进行长期研究.
- 在CML患者中,HU可以作为初始细胞减少的辅助疗法,这些患者有超粘度或白细胞静止症状.

Combination Therapies and Personalized Medicine
5.8K
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...

Treatment Resistant Cancers
3.7K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

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.
