摘要 目的探讨影响幕上大脑半球间变性星形细胞瘤显微手术后生存预后的因素。方法回顾59例间变性星形细胞瘤接受显微手术与术后辅助性放疗及化疗的临床资料,随访生存状况并用免疫组化技术检测肿瘤标本Ki-67、P53表达,用Kaplan-Meier单因素生存分析与Cox多元回归分析作统计学处理。结果间变性星形细胞瘤中位无进展生存期(PFS)18个月,中位总生存(OS)期21个月。单因素分析显示,年龄、治疗前KPS评分、术前有抽搐症状、术前MRI检查肿瘤强化,Ki-67过表达、P53表达与患者PFS和OS显著相关(P〈0.05)。性别、肿瘤直径、肿瘤部位、肿瘤切除程度与患者PFS、OS无关(P〉0.05)。Cox多元回归分析显示,年龄、KPS评分、抽搐症状、P53表达、Ki-67过表达仍是影响预后的显著因素,而肿瘤是否强化与生存预后无关。结论年龄较小、KPS评分高、术前抽搐症状、Ki-67低表达、P53表达是高级别星形细胞瘤生存预后良好的因素,而性别、肿瘤大小、部位和手术切除程度与预后无关。
