概括

2022年世界卫生组织分类将寡头单细胞性CMML (O-CMML) 纳入主要疾病. O-CMML表现出独特的特征和有利的风险,这表明它是慢性骨髓单细胞白血病的独特亚型.

科学领域:

血液学血液学血液学
在瘤学瘤学.
临床病理学临床病理学

背景情况:

2022年世卫组织分类修订了慢性骨髓单细胞白血病 (CMML) 的诊断标准.
以前被称为寡头单细胞性CMML (O-CMML) 的变种被纳入了CMML诊断中.
目前,CMML被分为骨髓发育性 (MD-CMML) 和骨髓增殖性 (MP-CMML) 形式的亚型.

研究的目的:

分析CMML患者的临床特征和长期结果,包括以前被归类为O-CMML的患者.
评估O-CMML在修订后的CMML分类中的重要性.

Disorders of Leukocytes

Disorders of Leukocytes

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...

Differentiation of Common Myeloid Progenitor Cells

Differentiation of Common Myeloid Progenitor Cells

Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...
