概括

结直肠多瘤中的血管侵入,这是腺瘤组织进入血管的现象,可以通过特定的组织学特征来区分出真正的血管入侵. 这种良性过程似乎与复发性或转移性癌症无关.

科学领域:

胃肠道病理胃肠道病理
结肠直肠癌研究研究
手术病理学手术病理学

背景情况:

结直肠腺瘤中的血管侵入是一个鲜为人知的现象.
区分它与真正的血管侵袭对于准确的诊断和患者管理至关重要.

研究的目的:

在结直肠腺瘤中验证血管侵入的存在.
描述区分血管侵入与真正血管入侵的组织学特征.

主要方法:

三位胃肠道病理学家在两个队伍中评估了38个结肠直肠多.
诊断标准是通过共识会议来确定的.
鉴定出有利于血管侵入的组织学特征.

主要成果:

在改进标准后,对诊断的同意率从53%增加到74%.
达成共识的诊断是血管侵入 (21例) 和血管入侵 (7例).
10个病例仍然没有被协商一致诊断出来.
血管侵入患者的随访没有显示复发或转移性癌症.

结论:

血管侵入很可能是聚处理或上皮质错位的工件.
特定的组织学特征可以帮助区分这种良性现象与真正的血管入侵.
血管侵入似乎并不表明预后更差.

关键词:

腺瘤腺瘤是一种艺术品文物工艺品一个血管,一个血管.大肠是大肠中的一个.错误诊断是一个错误的诊断.

Metastasis

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Cancer Cell Migration through Invadopodia

Cancer Cell Migration through Invadopodia

Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...
