Overexpression of HER2 may be associated with high histologic grade, er - tumors, greater proliferation, larger tumor size, and thus a poor prognosis.
HER2的过分表达可能与组织学等级高、ER -肿瘤、增生扩大、肿瘤较大及因此而致的预后不良有关。
Conclusions The proliferative activity and apoptosis of meningiomas are correlated with the tumor grade.
结论脑膜瘤的增殖活性和细胞凋亡与肿瘤级别相关；
The expression of mutation P53 protein was related closely to histopathologic grade, tumor size, metastasis and prognosis of tumor(P<0.05), but it was not related to histologic types(P>0.05).
P53蛋白的阳性表达与组织学分级、肿瘤预后复发及肿瘤大小关系密切（P＜0．05），但与组织学类型无相关性（P＞0．05）。
