概括

特定的微血管形状,如C形和X形,与食道癌的较差结果有关. 这些发现为这种侵袭性疾病提供了超越传统微血管密度的新预后标记.

科学领域:

在瘤学瘤学.
病理学病理学病理学
血管生物学血管生物学

背景情况:

血管生成对瘤生长至关重要,微血管密度 (MVD) 用于评估食道癌.
在食道癌中MVD的预后价值是有争议的,促使对微血管架构进行侵略性评估的研究.

研究的目的:

为了确定与食道状细胞癌的攻击性相关的瘤微血管的组织学特征.
为了评估特定的微血管形态在食道癌症的预后意义.

主要方法:

在108个食道状细胞癌组织的免疫组合化学染色中,使用了CD31,alpha光滑肌动蛋白和VEGF-A.等标记物.
通过显微镜评估微血管密度 (MVD),微血管细胞覆盖率指数 (MPI) 和瘤血管形态.

主要成果:

与MPI或总体VEGF-A表达不同,MVD与患者的结果有显著的相关性.
C形和X形的微血管与预后不佳和先进的临床病理特征有显著的关联.
焦点VEGF-A表达在具有C形或X形微血管的区域更高.

结论:

呈现C形和X形形态的瘤微血管显示为食道状细胞癌的预后因素.
与传统的MVD评估相比,这些特定的微血管结构可能会提供更好的预后见解.

The Tumor Microenvironment

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
