概括
不确定的意义的单克隆性淋巴瘤病变 (MGUS) 逐渐发展为血液性恶性瘤 (HM) 估计每年1.2%和多发性骨髓瘤 (MM) 每年0.8%. 广泛的研究变化凸显了对MGUS进展因素的进一步研究的需要.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 医学统计 医学统计
背景情况:
- 意义不明的单克隆性胃病变 (MGUS) 是等离子体细胞失光症的前体,如多发性骨髓瘤 (MM).
- 目前的指导方针表明,MGUS的每年恶性进展率约为1%转变为血液性恶性瘤 (HM),但报告的比率有显著差异.
研究的目的:
- 系统地审查和元分析从MGUS到HM,特别是到MM的恶性进展率.
- 解决报告的MGUS进展率中的差异,并提供最新的估计.
主要方法:
- 在2024年3月28日之前,对四个电子数据库进行了系统审查.
- 用元分析和叙事综合来总结1991年至2024年间在17个国家发表的46项研究的结果.
- 包括的研究中,随访时间的中位数从1.3年到34.2年不等,样本大小从63人到17963人.
主要成果:
- 从MGUS到HM的整体估计年进展率为1.2% (95%CI:1.0%-1.5%),相当于每1000人年12次事件.
- 从MGUS到MM的整体估计年进展率为0.8% (95%CI:0.7%-1.1%),相当于每1000人年有8次事件.
- 研究之间观察到实质性的异质性 (I2:HM的96.7%,MM的95.8%),10年进展率从6.6%-33.6%变化为HM和7.0%-28.5%变化为MM.
结论:
- 虽然整体进展率与临床指南一致,但研究之间存在显著的异质性.
- 需要进一步的研究来探索影响MGUS进展的因素,例如地理区域,随访持续时间和研究方法.
- 临床医生和患者在讨论从MGUS发展为MM的风险时应谨慎行事,因为报告的发病率范围广泛.

Tumor Progression
7.7K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Disorders of Leukocytes
2.2K
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...
