目的 :探讨立体定向 32 P内放射治疗脑星形细胞瘤的病理观察及临床预后。方法 :对 45例不同分化程度的脑星形细胞瘤进行治疗及对照观察 ,6例行手术切除脑星形细胞胶质瘤送病理检查。结果 :随访 6个月～ 5年 ,恢复正常生活或工作者 2 4例 ,占 5 3 3 % ;症状改善及肿瘤缩小、稳定 15例 ,占 33 3% ;死亡 6例 ,占 13 4% ;有效治疗率 86 6 % (39/ 45 )。病理检查 :肿瘤组织 90 %坏死。结论 :32 P内放射治疗是一种安全 ,简便 ,经济 ,疗效确切 ,病死率低的治疗方法
Objective: To investigate the pathological observation and clinical prognosis of stereotactic 32 P radiation treatment of brain astrocytoma. Methods: 45 cases of different degree of differentiation of brain astrocytoma were treated and controlled observation, 6 cases of surgical resection of brain astrocytoma glioma sent pathology. Results: Followed up for 6 months to 5 years, 24 cases returned to normal life or workers, accounting for 53.3%. 15 cases were cured and 33 3% were stable. The death rate was 13.4%. The effective treatment rate was 86.6% (39/45). Pathological examination: tumor tissue 90% necrosis. Conclusion: Radiotherapy within 32 P is a safe, simple, economical and effective treatment with low case fatality rate
