概括
对于核心结合因子急性髓性白血病 (CBF-AML) 的化疗添加达沙替尼并没有改善生存结果. 与单独使用标准化疗相比,组合疗法增加了严重不良事件.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 临床试验 临床试验
背景情况:
- 核心结合因子急性髓性白血病 (CBF-AML) 的特征是KIT突变和改变KIT表达.
- 在CBF-AML患者中经常观察到KIT突变.
研究的目的:
- 评估加达沙替尼 (dasatinib) 于CBF-AML的成年患者的密集化疗的疗效和安全性.
- 为了比较标准化疗和大沙替尼增强化疗之间的无事件生存期 (EFS).
主要方法:
- 一个随机的,开放的,第三期试验,涉及202名患有CBF-AML的成年患者.
- 患者接受了标准的诱导和巩固化疗,试验组同时接受达沙替尼,并作为维持疗法.
- 主要终点是无事件生存 (EFS);次要终点包括整体生存率和复发率.
主要成果:
- 在标准化疗手臂和达沙提尼布手臂之间没有观察到EFS的统计学上显著差异 (HR 0.92,p=0.66).
- 根据年龄,CBF-AML类型和KIT突变状态进行的子组分析也显示,达沙替尼对EFS没有显著改善.
- 严重不良事件的发生率在达沙替尼手臂 (64%) 与标准手臂 (36%) 相比显著更高.
结论:
- 在强化化疗中添加达沙替尼不改善CBF-AML患者的生存结果.

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...

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

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.

Clinical Trials
10.1K
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
