目的回顾性分析脑转移瘤采用单纯放疗（R）、放疗加化疗（R＋C）、立体放射外科加放疗（SRS＋R）治疗效果及影响因素。方法1993年3月至1998年6月间对收治的脑转移瘤中有61例进行分组治疗观察。结果6月、12月、＞12月生存率及局部控制率R组分别为54．1％、16．3％、2．7％和16．2％，R＋C组分别为75％、33．3％、25％和41．6％，SRS＋R组分别为83．3％。58．3％、41．6％和91．6％。结论SRS＋R治疗脑转移瘤在延长患者生存期及局部控制上要优于R和R＋C组。
Objective To retrospectively analyze the therapeutic effect and influencing factors of brain metastases using radiotherapy (R), radiotherapy plus chemotherapy (R + C) and stereotactic radiosurgery plus radiotherapy (SRS + R). Methods Between March 1993 and June 1998, 61 cases of brain metastases were treated by grouping. Results The survival rates and local control rates in June, December and December were 54.1%, 16.3%, 2.7% and 16.2% respectively in the R group and 75% and 33.3% in the R + C group %, 25% and 41.6%, respectively, SRS + R group were 83.3%. 58.3%, 41.6% and 91.6%. Conclusions SRS + R treatment of brain metastases is superior to R and R + C groups in prolonging survival and local control.
