摘要 目的分析PTEN,Bcl-2,HSP70在星形细胞瘤中的表达及其与肿瘤分化和预后的关系。方法应用免疫组化S-P法对54例脑原发性星形细胞瘤中PTEN,Bcl-2,HSP70的表达进行观察,对其中41例取得随访资料的肿瘤患者存活因素进行分析。结果PTEN,Bcl-2,HSP70的表达在星形细胞瘤、间变型星形细胞瘤和多形性胶质母细胞瘤中差异有显著性(F=14.79,P<0.01;F=4.25,P<0.05;F=23.12,P<0.01)。PTEN在星形细胞瘤中标记指数高时,预后较好;Bcl-2和HSP70在星形细胞瘤中标记指数高时,预后较差。结论PTEN,Bcl-2,HSP70异常表达与星形细胞瘤分化与预后相关,能够客观反映肿瘤的增殖速度、分化和恶性程度,可以作为判断星形细胞瘤分化和预后有价值的参考指标。
