概括

患有全身性硬化症 (SSc) 的人患血液性恶性瘤的风险增加了一倍,特别是B细胞类型. 这种增加的风险在被诊断为SSc的男性和年轻成年人中最高.

科学领域:

风湿病学和血液学风湿病学和血液学
流行病学和公共卫生.

背景情况:

系统性硬化症 (SSc) 是一种复杂的自身免疫性疾病,可能与二级恶性瘤有关.
了解与SSc相关的特定癌症风险对于患者监测和管理至关重要.

研究的目的:

与一般人群相比,评估SSc患者血液恶性瘤的风险.
调查这种风险如何根据性别和年龄不同.
确定SSc诊断与这些恶性瘤发病之间的时间关系.

主要方法:

一项全国性的队列研究,利用瑞典2004-2019年的行政医疗保健登记册.
包括SSc患者和匹配的一般人群对照者.
使用波桑回归和危险比率 (HRs) 分析血液恶性瘤发病率,使用灵活的参数模型,按性别和年龄分层.

主要成果:

患有SSc的个体患有血液性恶性瘤的风险增加了2.2倍 (HR 2.2,95% CI 1.4-3.1),B细胞恶性瘤的风险增加了3.0倍 (HR 3.0,95% CI 1.7-4.8).
在男性和在SSc诊断时18-49岁的个体中,风险明显更高.
骨髓状瘤恶性瘤出现在SSc诊断时间附近 (诊断后平均0.1年),而淋巴状瘤恶性瘤出现在晚些时候 (诊断后平均3.1年).

结论:

患有SSc的患者面临着显著增加的血液恶性瘤的风险,特别是B细胞类型.
患有SSc的男性具有最高的风险.
恶性瘤呈现的时间不同,骨髓类型比淋巴类型更接近SSc诊断.

Regulation of Hematopoietic Stem Cells

Regulation of Hematopoietic Stem Cells

All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

Bone Marrow Sampling and Transplants

Bone Marrow Sampling and Transplants

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.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Hematopoiesis

Hematopoiesis

The process of blood cell formation is called hematopoiesis. Hematopoiesis starts early during development, on the seventh day of embryogenesis. This phase of hematopoiesis is called the primitive wave, wherein the extraembryonic yolk sac allows the production of erythroid cells and endothelial cells from a common precursor called hemangioblast. The erythroid cells provide oxygen to support the growth of the rapidly dividing embryo. Hemangioblasts later develop into hematopoietic stem cells or...
