大肠癌浸润的细胞外基质变化和内皮细胞的关系探讨

目的　探讨大肠癌浸润的细胞外基质变化和血管内皮细胞的关系,为了解大肠癌生物学行为改变和临床应用抑制细胞外基质降解治疗大肠癌的作用。　方法　应用免疫组化半定量分析。　结果　癌旁组、各期浸润组的细胞外基质成分和内皮细胞变化与正常组比较,有显著差异(P<005或P<001),LN、F8,CD34和肌动蛋白的增加,均与大肠癌的浸润有关。　结论　提示抑制癌细胞对细胞外基质的降解和对血管内皮细胞的损伤,可起到阻止癌细胞的游走和浸润

A STUDY ON THE RELATIONSHIP BETWEEN THE CHANGES OF EXTRACELLUAR MATRIX INVADED BY COLORECTAL CARCINOMA AND ENDOTHELIAL CELLS

PURPOSE To investigate the relationship between the changes of extracellular matrix invaded by colorectal carcinoma and vascular endothelial cells,which will be useful to understand colorectal carcinoma biological behavior and may have clinical significance in the treatment of colorectal carcinoma.METHODS Immunohistochemistry technique and semi quantitative analysis were used.RESULTS As to the changes of ECM and endothelial cells,there were significant differences among the paracarcinoma groups,different invasive groups and normal group.THe increase of LN,CD34,F8 and actin were correlated with colorectal carcinoma invasion( P <0 05 or P <0 01).CONCLUSIONS These results suggest the inhibition of the degradation of ECM and the damage of endothelial cells and may be able to prevent cancer cell migration and invasion.
