文献报道,肺癌脑转移的发生率约为23%-65%,约占颅内转移性肿瘤的40%-60%[1]。肺癌脑转移的病情发展快、预后差,是肺癌患者致残和死亡的重要原因。肺癌脑转移不治疗的自然病程多数为1-2个月;特别是以脑部症状为首发临床表现的那部分肺癌脑转移患者,就诊时缺少明显的呼吸系统症状,待发现肺癌脑转移已是晚期表现,延误了最佳治疗时机,预后最差。随着观念和技术的进步,特别
Reported in the literature, the incidence of brain metastases of lung cancer is about 23% -65%, accounting for about 40% -60% of intracranial metastatic tumors [1]. Lung cancer brain metastasis of the rapid development of the disease, the prognosis is poor, is an important cause of disability and death of lung cancer patients. Most of the natural history of non-treatment of brain metastases of lung cancer for 1-2 months; especially those with brain symptoms as the first clinical manifestation of that part of patients with brain metastases of lung cancer, lack of obvious respiratory symptoms at treatment, to be found in lung cancer brain metastases have been Late performance, delayed the best timing of treatment, the worst prognosis. With the progress of ideas and technology, special
