目的分析脑转移瘤的临床特点及影响预后因素。材料和方法利用１９８４年１０月到１９９６年５月，我院收治的经ＣＴ或ＭＲＩ证实的可供分析的脑转移瘤６８例，分析其临床特点和影响预后的因素。结果临床分析发现，原发肿瘤以肺癌最多。临床主要表现为颅内压增高、偏瘫、癫痫样抽搐、共济失调、精神情绪异常等。颅内转移部位主要在颞顶叶及额叶的大脑皮髓质交界处，单发与多发比例为１∶４．２。影响预后的因素主要为病人一般状况（ＫＰＳ）、有无颅外其他器官转移、治疗手段、放疗剂量。死亡原因中脑转移及其他部位转移仍占主要地位。结论脑转移病例的临床治疗应以放化综合治疗为主，病人一般状况是影响预后的主要因素。
Objective To analyze the clinical characteristics of brain metastases and prognostic factors. Materials and Methods From October 1984 to May 1996, 68 cases of brain metastases confirmed by CT or MRI admitted to our hospital were analyzed, and their clinical characteristics and prognostic factors were analyzed. Results Clinical analysis found that the primary tumor to lung cancer up. Main clinical manifestations of increased intracranial pressure, hemiplegia, epileptic convulsions, ataxia, mental disorders and so on. The site of intracranial metastasis mainly in the parietal and frontal cortex and medulla junction, single and multiple ratio of 1: 4.2. The main factors affecting the prognosis of the general condition of patients (KPS), with or without extracranial organ metastases, treatment, radiotherapy dose. The causes of death in the brain metastasis and other parts of the transfer is still dominant. Conclusion The clinical treatment of brain metastases should be the main radiotherapy comprehensive treatment, the general condition of patients is the main factor affecting the prognosis.
