概括
边缘区域淋巴瘤 (MZL) 中大细胞 (LCs) 的增加表明预后较差,无进展生存率较差,复发率更高. 这一发现可能有助于指导MZL患者的临床决策.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 病理学 病理学 病理学
背景情况:
- 边缘区域淋巴瘤 (MZL) 是一种惰的小B细胞淋巴瘤,具有结节,脏和外结节MALT亚型.
- 虽然MZL通常生长缓慢,但在诊断时可以表现出大细胞 (LCs) 的增加,其临床意义尚未确立.
- 之前的研究已经在MZL中发现了LC,但它们的预后价值仍然不清楚.
研究的目的:
- 评估边缘区域淋巴瘤 (MZL) 中大细胞 (LCs) 增加的临床意义.
- 确定LCs的存在是否影响MZL无进展生存率,转变率和复发频率.
- 评估不同MZL亚型中LC的预后价值.
主要方法:
- 在1994年至2021年间诊断的161例MZL病例的回顾性分析.
- 病例的分类是基于存在 (>10 LCs/hpf) 或没有增加的 LCs.
- 统计分析比较了临床特征,包括Ki-67指数,阶段,转变为DLBCL,以及组之间的复发率.
主要成果:
- 增加LC的MZL病例显示Ki-67扩散指数显著更高 (≥30%).
- 增加的LC与更糟糕的无进展生存率,更高的诊断阶段,增加转变为DLBCL和更高的复发频率有关.
- 亚组分析表明,结节和MALT LC组的结果更差,MALT LC病例呈现的阶段更高,变化更频繁.
结论:
- 在MZL中增加大细胞的存在是预后较差的重要指标.
- 在MZL中的LC与侵略性特征相关,包括更高的扩散,高级阶段,转变和复发.
- 识别MZL中的LC可以作为指导临床管理和治疗决策的有价值的预后标记.

Disorders of Leukocytes
982
Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...

Secondary Lymphoid Organs
1.6K
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...
