概括
患有超白细胞瘤的儿童白血病患者面临更早的并发症和更差的生存率,特别是在急性淋巴细胞白血病中. 早期发现和管理高白细胞计数对于改善结果至关重要.
科学领域:
- 儿科瘤学 儿科瘤学
- 血液学 血液学 血液学
背景情况:
- 超白细胞症 (WBC > 100 × 10 ^ 9 / L) 和极端超白细胞症 (WBC > 200 × 10 ^ 9 / L) 与白血病的不良结果有关.
- 了解儿科白血病的早期并发症和生存影响至关重要.
研究的目的:
- 为了调查儿童白血病患者的早期并发症和生存结果,他们被诊断出患有高白血细胞症.
- 确定与儿科急性淋巴细胞白血病 (ALL) 和急性骨髓性白血病 (AML) 过高白血球症的整体存活率相关的风险因素.
主要方法:
- 对690名新诊断患有急性白血病的儿童 (1998-2017年) 的医疗记录进行了回顾性审查.
- 卡普兰-梅尔方法和存活分析的日志级别测试.
- 多变量考克斯比例危险回归用于风险因素识别.
主要成果:
- 超白细胞症发生在16.6%的ALL和20.3%的AML患者中.

Disorders of Leukocytes
987
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...

Bone Marrow Sampling and Transplants
363
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.

Differentiation of Common Myeloid Progenitor Cells
3.2K
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...

Structure and Function of Leukocytes
2.1K
An adult in good health typically has between 4,500 and 11,000 leukocytes, or white blood cells, per microliter of blood, which constitutes about 1% of the total blood volume. Unlike red blood cells, white blood cells contain a nucleus and other cellular organelles but do not have hemoglobin. Most white blood cells reside in connective tissues, particularly in lymphatic organs such as the lymph nodes, with only a small fraction present in circulating blood.
