1974年3月～1984年6月,在本院行术后放疗及单纯放疗颅脑肿瘤26例,放疗后3及5年的生存率分别为57.7％和54.2％,其中胶质瘤分别为46.7％和42.8％;垂体瘤分别为66.7％和62.5％,肿瘤全切除比部分切除的术后放疗效果好,前者3年、5年生存率均为100％,而后者10例均在3年内死亡。放疗剂量以51～60 Gy组为佳。本组病例表明放疗过程中防止颅内压增高的措施是非常重要的。 From March 1974 to June 1984, 26 patients underwent postoperative radiotherapy and radiotherapy alone in this hospital. The survival rates at 3 and 5 years after radiotherapy were 57.7% and 54.2%, respectively, of which 46.7 were gliomas. % and 42.8%; pituitary adenomas were 66.7% and 62.5%, respectively. Total tumor resection was better than partial resection after radiotherapy. The former had 3-year and 5-year survival rates of 100%, while the latter 10 cases all died within 3 years. . The radiation dose is preferably 51 to 60 Gy. This group of cases shows that measures to prevent intracranial hypertension during radiotherapy are very important.
