概括
初级中枢神经系统淋巴瘤 (PCNSL) 是具有侵略性的,但对高剂量甲醇化疗的初始反应预测了生存. 对预测生物标志物的进一步研究是必要的,以改善PCNSL的治疗结果.
科学领域:
- 在瘤学瘤学.
- 血液学 血液学 血液学
- 基因组学就是基因组学.
背景情况:
- 初级中枢神经系统淋巴瘤 (PCNSL) 是一种罕见的,侵袭性的非霍奇金淋巴瘤.
- 基于高剂量甲基酸盐 (HDMTX) 的化疗是常见的,但复发率在5年内接近50%.
- 目前的分子变化 (MYD88,CD79,CDKN2A) 缺乏预测或预后价值.
研究的目的:
- 评估PCNSL初始治疗反应的预后意义.
- 确定PCNSL治疗反应的潜在生物标志物.
主要方法:
- 在2011-2023年期间接受治疗的40名PCNSL患者的回顾性审查.

Primary Lymphoid Organs
7.0K
Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...

Cells of the Adaptive Immune Response
4.7K
The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...
