摘　　要：1977年5月～1991年2月间对29例脑干肿瘤患者进行单纯放射,症状改善率为69.0%(20/20),1、2、3年生存率分别为58.6%(17/29)、44.8%(13/29)、31.0%(9/29),接近国外之同类报道。在有病理诊断的6例皆活过3年,占存活的66.7%(6/9)。结果证明,照野不宜过大,放疗中须防脑水肿,失败主要原因为剂量低造成原病灶未挖和复凝。通过明确病理诊断,采用目前国外已开展而1国内尚未见报道的脑干肿瘤超分割放射的新方法可望提高疗效。In this article, a retrospective analysis was made on the results of radiotherapy applied exclusively in treating 29 cases of brainstem tumor from May 1977 to February 1991 with the dosage ranging from 40. 6～68GY/5～7weeks. Of the 29 patients, 20(69.0%)reSponded well to the initial radiotherapy. The 1-, 2-, and 3 years survival rates were 58.6% (17/29), 44.8%(13/29), and 31.0% (9/29) respectively. The main cause of failure in treatment was the insufficient dosage applied. It is suggested that the hyperfractionated radiotherapy is more preferable for brainstem tumor.
