目的:探讨髓母细胞瘤的诊断及外科治疗方式。方法:应用显微外科技术治疗78例,男50例,女28例,平均年龄9.8岁。结果:64例获全切,14例次全切。术后1～3d内死亡3例,手术病死率3.8％。随访59例,随访时间1～7年(平均3.8年),平均生存时间4.7年,5年生存率为47％。结论:在显微手术下争取达到肿瘤完全切除并尽量减轻脑干等结构损伤,术后及时予以放射治疗是降低手术死亡、提高生存率的重要措施。
Objective: To investigate the diagnosis and surgical treatment of medulloblastoma. Methods: 78 cases were treated by microsurgical technique, including 50 males and 28 females, with an average age of 9.8 years. Results: 64 cases were cut, 14 cases total cut. 3 cases died within 1 ~ 3 days after operation, and the operative mortality rate was 3.8%. Fifty-nine patients were followed up for 1 to 7 years (average, 3.8 years) with an average survival time of 4.7 years and a 5-year survival rate of 47%. Conclusion: To achieve complete tumor resection and minimize the damage of brain stem and other structures under microsurgery, timely radiotherapy after surgery is an important measure to reduce surgical death and improve survival rate.
