Identification of vasculogenic mimicry in astrocytoma and its clinical significance
摘要
Abstract
Objective To investigate vasculogenic mimicry (VM) in astrocytoma and its clinical significance. Methods Three-dimensional culture system of U87 cells was constructed to observe VM. The presence of VM in 65 specimens of astrocytoma was observed by immunohistochemical and histological double staining of CD34 and PAS. Results After three-dimensional culture, U87 cells remolded and fused with each other, forming wreath and network structure. The immunohistochemical and histological double staining showed that VM was present in astrocytoma. VM was not found in grade Ⅰ and Ⅱ astrocytoma. The positive rate of VM in grade Ⅳ group (7/25) was significantly higher than that in grade Ⅲ group (3/18). VM density was 8.81±2.84/HP in grade Ⅳ group and 5.55± 3.13/HP in grade Ⅲ group; it increased with the increase of malignancy. There were significant differences between the groups. Conclusion VM is present in astrocytoma and it is correlated with the malignancy.关键词
