概括
一名慢性淋巴细胞白血病患者在服用低剂量的奥比努祖马布后实现了缓解,显示出异常敏感性. 这一案例突出了即使在有限的venetoclax治疗中也可能的疗效.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
背景情况:
- 根据CLL-14试验,奥比努图祖马布与venetoclax结合是慢性淋巴细胞白血病 (CLL) 的标准治疗方法.
- 逐渐增加奥比努祖马布的剂量旨在最大限度地降低毒性并预防瘤溶解综合征.
- 虽然增加剂量在治疗上是有效的,但它们不被认为是最终的治疗方法.
研究的目的:
- 报告慢性淋巴细胞白血病患者对奥比努祖马布初始升级阶段的异常反应.
- 为了研究早期不良事件后有限的venetoclax治疗后的临床结果.
主要方法:
- 一个73岁的女性患有CLL的病例报告,根据CLL-14协议进行治疗.
- 治疗涉及初始低剂量奥比努图祖马布,随后由于严重的泛细胞衰竭而进行venetoclax.
- 通过骨髓活检和外围血液流动细胞计量来评估反应.
主要成果:
- 患者在初始的奥比努图祖马布剂量后经历了严重的泛细胞衰竭,导致治疗修改.
- 尽管有限的venetoclax,骨髓活检显示只有0.14%的CLL细胞.
- 患者在obinutuzumab治疗后34个月内实现并维持了完全缓解.
结论:
- 患者对最小剂量奥比努祖马布的显著反应表明异常敏感.
- 这一案例表明,即使是有限的对奥比努祖马布的暴露,也可以导致CLL的持久缓解.

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...

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...

Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...
