概括
免疫组织化学可以识别表达性淋巴瘤 (EL),一种侵略性的扩散型大B细胞淋巴瘤 (DLBCL) 的亚型. 这种查方法有助于检测需要密集化疗的病例,以获得更好的结果.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 病理学 病理学 病理学
背景情况:
- 双重或三重击中淋巴瘤 (DHL/THL) 的预后比扩散大B细胞淋巴瘤,NOS (DLBCL,NOS) 更糟糕.
- 识别激进的HGBL/DLBCL亚型有助于选择患者接受密集化疗.
- 对表达性淋巴瘤 (EL) 的免疫组织化学 (IHC) 提供了一种具有成本效益的查方法,用于潜在的Hit状态.
研究的目的:
- 为了确定印度人口中EL的流行率.
- 为了比较表达性淋巴瘤 (EL) 和非表达性淋巴瘤 (NEL) 之间的临床和病理参数.
主要方法:
- 包括131名被诊断为高级大B细胞淋巴瘤 (HGBL) 的患者.
- 分析了临床数据 (年龄,性别,瘤部位,B型症状) 和病理参数 (Ki67,GC/非GC型表型).
- 利用免疫组织化学 (IHC) 将病例分类为EL或NEL.
主要成果:
- 22.2%的HGBL病例被归类为EL,其中77.8%为NEL.
- 与NEL相比,EL病例的平均Ki67扩散指数 (p=0.025) 显著高于NEL.
- 在EL和NEL之间没有发现年龄,性别,瘤部位,B症状,LDH水平或GC/非GC表型的显著差异.
结论:
- 对于所有DLBCL病例,IHC检测表达器状态被推作为查工具.
- 在DLBCL病例中,很大一部分可能是EL,这表明攻击性行为和可能需要加强治疗.
- 这种IHC方法可以确定需要进一步分子研究以检测命中状态的病例.

Secondary Lymphoid Organs

Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

Primary Lymphoid Organs

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...
