摘要 目的探讨星形胶质细胞瘤中热休克蛋白(HSP70)表达水平与肿瘤恶性程度的关系及其与胶质细胞瘤生物学行为的关系。方法采用HSP70单克隆抗体对62例星形胶质瘤进行免疫组化染色,检测HSP70的表达水平及其与胶质瘤病理分级的关系,随访观察患者5年生存率,比较不同HSP70表达水平下患者的生存率差异。结果 62例星形胶质细胞瘤患者中,21例HSP70表达增高,与正常脑组织有统计学差异(P<0.05);HSP70表达情况与性别、年龄无关(P>0.05);HSP70的表达水平与胶质瘤病理分级呈正相关(r=0.685,P<0.01);HSP70阳性组5年生存率明显低于HSP70阴性组(χ2=4.742,P<0.05)。结论 HSP70与胶质瘤的生物学行为和分化程度有关,HSP70的检测会对星形胶质细胞瘤的诊断与靶向治疗提供实验依据。
