概括
在毛囊性淋巴瘤 (FL) 患者中降低bendamustine剂量可能会使无进展生存期 (PFS) 恶化. 维持全剂量强度对于响应者来说至关重要,以改善FL治疗的结果.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 临床药理学 临床药理学
背景情况:
- 在以前未经治疗的卵泡淋巴瘤 (FL) 中,减少本达穆斯丁剂量是常见的,但其对患者结局的影响尚不清楚.
- 毛囊淋巴瘤治疗策略通常涉及基于临床因素的剂量调整.
研究的目的:
- 在以前未接受过治疗的FL患者中调查本达穆斯丁剂量减少的预后意义.
- 确定是否保持全剂量强度会影响整体存活率 (OS) 和无进展存活率 (PFS).
主要方法:
- 在七个日本机构中,对92名未经治疗的FL患者进行了回顾性分析,这些患者接受了bendamustine治疗.
- 剂量减少被定义为在六个周期内接受计划的1080 mg/m2总剂量的<90%.
- 通过在180天内进展确定的初级达慕斯耐药 (PBR) 患者.
主要成果:
- 整体队列显示3年的生存率为87.1%,PFS为71.8%.
- 降低剂量与显著较低的完全响应 (CR) 率 (74.4%对93.0%) 和更糟糕的3年PFS (68.1%对86.8%) 相关.
- 即使在CR患者中,剂量降低与3年的PFS相对较差 (72.7%与85.7%相比).
结论:
- 主要抗胺素耐药 (PBR) 的FL患者似乎固有抗胺素,无论剂量强度如何.
- 对于对bendamustine反应良好的FL患者来说,维持治疗强度对于实现更好的PFS和预后至关重要.
- 在FL治疗中,降低剂量会对PFS产生负面影响,这凸显了在可行的情况下全剂量注射的重要性.

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.

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...
