概括
在慢性髓性白血病 (CML) 中,第二次尝试 (TFR2) 后无治疗缓解是可行的. 获得深度分子反应的患者可以在重新治疗后尝试TFR2,尽管对晚期复发的仔细监测至关重要.
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:
- 氨酸激酶抑制剂 (TKIs) 已经使慢性髓性白血病 (CML) 患者的长期存活率正常化.
- 许多CML患者在初始TKI中止后实现无治疗缓解 (TFR1).
- 第二次TKI停产尝试 (TFR2) 的成功程度仍然不太清楚.
研究的目的:
- 评估CML中第二次TKI中止 (TFR2) 后无治疗缓解的可行性和结果.
- 确定TFR2.2患者的患者资格标准和最佳的再治疗策略.
- 分析TFR2.2的潜在挑战和监测要求.
主要方法:
- 对5项临床试验和2项关于TFR2.2的现实世界报告的系统审查.
- 对有关分子反应 (MR4.0或更深) 和TKI再处理的患者数据的分析.
- 评估与伊马替尼,尼洛替尼和达沙替尼对TFR2巩固的耐受性和不良事件.
主要成果:
- 在符合条件的患者中,在重新接受意马替尼,尼洛替尼或达萨替尼治疗后,TFR2似乎是可行的.
- 资格要求达到持久的MR4.0或更深的分子缓解.
- 伊马替尼布在巩固方面耐受良好;尼洛替尼布和达沙替尼布可能会导致影响耐受性的不良反应.
- 经常观察到晚期 (>1-2年) 的复发,需要谨慎监测.
结论:
- 在第二次TKI中止 (TFR2) 后的无治疗缓解是选择慢性髓性白血病患者的可行选择.
- 实现深度分子缓解和仔细选择再处理剂是成功TFR2.2的关键.
- 长期监测是必不可少的,因为在TFR2.2后出现晚期复发的风险.

Treatment Resistant Cancers
3.3K
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...

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...
