脑干(包括丘脑)肿瘤因解剖部位和生理功能的重要性,难以作手术全切,化疗效果不佳,故以放疗为主.我院自1975年5月～1989年2月,采用手术(部分切除和托氏分流术)加放射治疗12例,单纯放射治疗22例,回顾分析两种方法的治疗结果,重点探讨本病的治疗方案和手术作用.34例中男21例,女13例.年龄5岁～64岁,平均年龄28岁±5.53岁.肿瘤位于丘脑14例,其中累及侧脑室4例;脑桥18例,累及Ⅳ脑室、小脑4例、全脑干2例;中脑累及丘脑和脑桥1例;延髓累及Ⅳ脑室1例.诊断主要根据临床、气脑、脑室造影、CT检查和手术所见.获病理诊断者9例均为星形细胞瘤,其中Ⅰ级3例,Ⅱ级4例,Ⅲ和Ⅳ级各1例.
Brain stem (including the thalamus) tumor due to the importance of anatomical sites and physiological functions, it is difficult to make the whole operation, chemotherapy is not good, so the main radiotherapy.Our hospital from May 1975 to February 1989, the use of surgery Partial resection andTorchis shunt) plus radiation therapy in 12 cases, radiotherapy alone in 22 cases, retrospectively analyzed the results of two methods of treatment, focusing on the treatment of this disease and surgical effects .34 cases of male 21 cases, female 13 cases .The age ranged from 5 years old to 64 years with a mean age of 28 years ± 5.53 years.The tumors were located in the thalamus in 14 cases, involving 4 cases in the lateral ventricle, 18 cases in the pontine, involving IV ventricle, 4 cases in the cerebellum and 2 cases in the brain stem. 1 case of thalamus and pons, and 1 case of medulla oblongata involving IV.Diagnosis was mainly based on clinical, pneumo-cerebral, ventriculogram, CT and surgery.All 9 cases were pathologically diagnosed astrocytoma, of which 3 cases were grade Ⅰ, Ⅱ grade in 4 cases, Ⅲ and Ⅳ grade in 1 case.
