概括
在接受Rituximab加化疗 (R-chemo) 的毛囊性淋巴瘤 (FL) 患者中,外节参与 (ENI) 对结果产生负面影响. 然而,Rituximab加上lenalidomide (R2) 疗法可以克服这种情况,建议R2作为ENIFL的潜在治疗策略.

- 遗传学 遗传学 是一个
背景情况:
- 毛囊性淋巴瘤 (FL) 是最常见的惰性非霍奇金淋巴瘤.
- 在接受基于rituximab的免疫化疗的FL患者中,外节干涉 (ENI) 与糟糕的结果有关.
- 驱动ENI在FL中的分子机制需要进一步阐明.
研究的目的:
- 研究瘤基因突变和瘤微环境改变对毛囊淋巴瘤 (FL) 外节参与 (ENI) 的影响.

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...

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...
