概括
在一般人群中,瑞图西玛维护 (RM) 显著改善了新诊断的上衣细胞淋巴瘤 (MCL) 患者的生存率. 这项研究显示了RM的好处,特别是对于那些在R-CHOP化疗后实现部分缓解的人.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 临床试验和人口研究
背景情况:
- 新诊断的上衣细胞淋巴瘤 (MCL) 治疗通常包括rituximab (R) 加上 antracycline 化疗,有或没有自身干细胞移植 (ASCT).
- 在临床试验中,瑞图西马布维护 (RM) 已证明改善了整体存活率 (OS),但其对人口水平的影响不太清楚.
研究的目的:
- 评估西马布维护 (RM) 对新诊断的地幔细胞淋巴瘤 (MCL) 患者的结局对人口水平的影响.
- 评估三十年来MCL患者的生存趋势和RM对整体生存 (OS) 的影响.
主要方法:
- 根据荷兰癌症登记处的数据,对4751名在1989-2020年间被诊断为MCL的患者进行了回顾性分析.
- 患者被分类为反映Rituximab (R) 和Rituximab维护 (RM) 实施的时期 (1989-2000,2001-2014,2015-2020).
- 多变量分析 (MVA) 使用考克斯回归来确定RM与死亡率的关联,并根据相关因素进行调整.
主要成果:
- 对于MCL的五年相对存活率 (RS) 从38% (1989-2000年) 显著改善到60% (2015-2020年) (p<0.01).
- 到2014年,在80%的年轻患者和50%的老年患者中,Rituximab维护 (RM) 已经实施.
- RM与死亡率降低独立相关 (HR 0.69; 95% CI, 0.53-0.90),特别是在R-CHOP诱导后实现部分缓解 (PR) 的患者中.
结论:
- 在过去30年中,地幔细胞淋巴瘤 (MCL) 的总生存率提高了20%以上,反映了治疗策略的进步.
- 瑞图西玛维护 (RM) 显示出在人群水平上显著的生存益处,特别是在对初始R-CHOP治疗反应良好的患者中.
- 疾病的早期进展仍然是与MCL患者的不良结果相关的关键因素.

Maintenance of the ES Cell State
2.8K
The cells of the blastocyst inner cell mass only remain pluripotent for a short time. This state of pluripotency and self-renewal can be maintained in embryonic stem (ES) cell culture by adding specific chemicals or growth factors to ensure the cells can continue dividing and later differentiate into different cell types. In some cases, the cells are grown on a feeder layer of differentiated cells, which provides the growth factors and extracellular matrix components necessary for stem cell...

Conservation of Small Populations
17.4K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

What is Population Genetics?
64.8K
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

Population Growth
28.6K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

Cancer Stem Cells and Tumor Maintenance
6.0K
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...
