概括
二次性中枢神经系统大B细胞淋巴瘤 (SCNSL) 结果因呈现而异. 与CAR-T疗法相比,Thiotepa自身干细胞移植 (ASCT) 显示出更好的生存率,特别是新发性或中枢神经系统隔离的复发,与CAR-T治疗相比.
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:
- 二次性中枢神经系统 (CNS) 大型B细胞淋巴瘤 (SCNSL) 由于不同的环境和缺乏治疗共识,提出了挑战.
- SCNSL可以发生 de novo,作为中枢神经系统隔离的复发,或同步复发与系统性参与.
研究的目的:
- 评估国际SCNSL患者队列中的治疗结果.
- 为了确定预后因素,并比较特殊疗法后的存活率,如thiotepa自身干细胞移植 (ASCT) 和CAR-T疗法.
主要方法:
- 分析了1139名SCNSL患者 (de novo和复发) 的一个国际队列.
- 报告了无进展生存率 (PFS),总生存率 (OS) 和复发累积发生率 (CIR).
- 用多变量基准分析和倾向分数匹配 (PSM) 来比较治疗结果.
主要成果:
- 两年PFS估计为40.4% (de novo),43.9% (中枢神经系统隔离复发) 和16.2% (同步复发).
- 中枢神经系统隔离的复发有较低的系统性复发率 (24个月CIR 6%).
- 提奥特巴-ASCT与改善的PFS和OS相关联,在新发作和中枢神经系统隔离的复发中,以及同步复发中. 蒂奥特帕-ASCT显示的生存率高于PSM后的CAR-T.
结论:
- 对于符合条件的SCNSL患者,特别是那些新发病或中枢神经系统隔离的复发患者,支持Thiotepa-ASCT.
- 中枢神经系统隔离的复发很少导致系统性复发,这表明初级中枢神经系统淋巴瘤治疗方法可能是合适的.
- 治疗策略应考虑特定的SCNSL表现,以优化患者的治疗结果.

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...

Secondary Lymphoid Organs
8.8K
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
