概括
高剂量的甲状腺素 (HD-MTX) 在侵袭性B细胞淋巴瘤患者中没有显著降低中枢神经系统 (CNS) 的进展. 该研究没有发现HD-MTX在高危人群中对中枢神经系统预防有临床意义的益处.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 神经科学是一个神经科学.
背景情况:
- 中枢神经系统 (CNS) 的进展是一种罕见但严重的并发症在攻击性B细胞淋巴瘤.
- 最佳的中枢神经系统预防策略仍在争论中,特别是在高风险患者中.
研究的目的:
- 评估高剂量甲状腺 (HD-MTX) 在高风险的侵袭性B细胞淋巴瘤患者中预防中枢神经系统进展的疗效.
- 确定HD-MTX是否能显著降低中枢神经系统复发率.
主要方法:
- 国际,回顾性,观察性研究,包括18-80岁的患有侵袭性B细胞淋巴瘤和高中枢神经系统风险的患者.
- 基于HD-MTX使用的中枢神经系统进展的因特定危险比率和累积风险的分析.
- 从诊断 (所有患者) 和治疗结束 (完全响应患者) 计算到中枢神经系统进展的时间.
主要成果:
- 在整体队列中,HD-MTX的使用与中枢神经系统进展的风险较低有关 (调整HR,0.59;P=.014).
- 在实现完全响应的患者中,这种关联在统计学上没有显著意义 (调整后HR,0.74;P=.29).
- 在高风险小组中,没有观察到HD-MTX明显降低中枢神经系统进展风险,两年风险为7.2%.
结论:
- 高剂量的甲状腺素 (HD-MTX) 与高风险的侵略性B细胞淋巴瘤患者中中枢神经系统进展风险的临床显著降低无关.
- 在接受HD-MTX的患者中,观察到的2年中枢神经系统进展风险为7.2%,与之前报告的高风险队列一致.
- 可能需要进一步的研究,以确定最佳的中枢神经系统预防策略,为这个患者群体.

178
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

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.
