脑胶质瘤放射治疗的预后因素分析

目的评价和分析脑胶质瘤患者放射治疗的预后因素。方法选择接受放射治疗的脑胶质瘤术后患者162例，采用COX模型对预后因素进行单因素和多因素分析。结果平均随访时间30个月，复发14例，死亡45例。单因素分析结果显示，病理分级、病理类型、放疗前功能状态、手术切除范围和年龄是影响胶质瘤患者总生存率的因素。多因素分析结果显示病理分级、病理类型、年龄、放疗前功能状态、手术切除范围和放疗技术是影响总生存率的独立预后因素。结论低分级胶质瘤、星形细胞瘤和少突胶质瘤、年龄≤40岁、放疗前Kamofsky评分≥80分和肿瘤全切是预后较好的独立因素。

Prognostic analysis of patients with cerebral glioma treated with radiotherapy

Objective To evaluate and analyse the prognostic factors of cerebral glioma treated with radiotherapy. Methods Records of 162 patients with cerebral glioma. Cox model was used for univariate and multivariate analysis. Results Mean follow- up time was 30 months, 14 patients relapsed, and 45 patients died. Univariate analysis showed that histologic grade, histologic type, Karnofsky performance state before radiotherapy, extent of resection, and age were significant predictors in association with overall survival rate of patients with glioma. Multivariate analysis showed that histologic grade, histologic type, age, Kamofsky before radiotherapy, extent of resection,and radiotherapy technology were independent prognostic factors of glioma. Conclusion Low grade, AC and OD, age≤40 years, Kamofsky >80 before radiotherapy, and total resection axe independent factors for predicting better survival of glioma patients.
