概括
在西班牙的现实环境中,tafasitamab加上lenalidomide (T/L) 在治疗复发性/耐药性扩散性大B细胞淋巴瘤 (R/R DLBCL) 中显示出有效性. 这种组合疗法耐受性良好,对无法接受密集治疗的患者有益.
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:
- 复发性/耐药性扩散性大B细胞淋巴瘤 (R/R DLBCL) 存在重大治疗挑战,特别是对于不适合强化治疗或CAR-T细胞治疗的患者.
- 塔法西他马布加列纳利多米德 (T/L) 的组合在第二阶段试验中已经证明有效,但需要现实数据来进行一致的验证.
研究的目的:
- 为了评估在西班牙接受tafasitamab加lenalidomide治疗的R/R DLBCL患者的现实结果.
- 评估与T/L治疗相关的安全性,疗效和预后因素在现实世界R/R DLBCL群体中.
主要方法:
- 对99名R/R DLBCL患者进行了回顾性分析,这些患者至少接受了一剂tafasitamab (ITT队列) 和83名患者至少完成了一次T/L周期 (疗效队列).
- 收集的数据包括整体响应率 (ORR),完整响应 (CR),无进展生存率 (PFS),整体生存率 (OS) 和与治疗相关的毒性.
- 统计分析确定了与PFS独立相关的因素.
主要成果:
- 在ITT和疗效队列中,ORR分别为51%和61% (CR:35%和42%).
- 中位数的PFS为4.9个月 (ITT) 和10.9个月 (有效性);中位数的OS为12.2个月 (ITT) 和21.8个月 (有效性).
- 较差的ECOGPS (2-4),双击淋巴瘤和先前治疗后的耐药/进展性疾病与更糟糕的PFS有关. 莱纳利多米德相对剂量强度显著影响了结果.
结论:

Tumor Immunotherapy
658
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Treatment Resistant Cancers
3.4K
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...
