概括
接受全源造血干细胞移植的患者面临17%的后续恶性新生体风险,特别是与慢性移植对宿主疾病相关的皮肤癌.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 移植免疫学 移植免疫学
背景情况:
- 全基性造血干细胞移植 (HSCT) 是血液恶性瘤的治愈疗法.
- 非骨髓衰变调节方案旨在减少与治疗相关的毒性,但可能会改变长期并发症的风险.
- 随后的恶性瘤 (SMNs) 是HSCT后的一个重大问题.
研究的目的:
- 调查SMN的发病率和类型,以非骨髓衰变性全源性HSCT.
- 确定与SMN发展相关的风险因素,包括慢性移植对宿主疾病 (GVHD).
主要方法:
- 在1998年3月至2023年8月期间,对1720名接受非骨髓衰变性全源性HSCT的患者进行了回顾性分析.
- 平均随访时间为12年.
- 观察到的SMN发病率与一般人口预期的发病率的比较 (如果有).
主要成果:
- 在12年的中位随访后,SMN的累积发病率为17% (95% CI,15%-19%).
- 非黑色素瘤皮肤癌是最常见的SMN (n=543),与慢性GVHD有显著的关联.
- 观察到93种其他SMN (与预期的73.4相比) 的统计学上显著的过剩 (p=0.03),由子宫腺癌,状唇和阴茎癌驱动,也与慢性GVHD相关.
结论:
- 接受非骨髓衰变性全原性HSCT的患者有很大风险患SMN,特别是非黑色素瘤皮肤癌.
- 在此程序后,慢性GVHD是皮肤和特定非皮肤SMN的重要风险因素.
- 大多数其他SMN的风险与一般人群的风险相当,这表明有针对性的监测方法是合理的.

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.

Stem Cell Therapy for Tissue Regeneration
4.0K
Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.

Cancer Stem Cells and Tumor Maintenance
4.7K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...
