肺癌脑转移的立体定向放疗

Stereotactic Radiotherapy in the Treatment for Brain Metastases from Lung Cancer

脑转移是癌症患者的主要转移部位,而肺癌是最常见的脑转移的原发病。对于脑转移患者,仅给予最佳支持治疗或内科治疗,中位生存期只有1~2个月,使用全脑放疗、立体定向放疗和手术后,患者生存期明显延长,但对于寡转移和多发转移患者,其治疗策略不同,同样对于如何选择不同的治疗方法,有必要进一步探讨。在延长患者生存期的基础上,尽量保存认知功能同样重要。

Brain metastasis is the main metastatic site of patients with cancer. Lung cancer is the most common primary disease of blain metastases. For patients with brain metastases,only treated with best supportive care or medical treatment,median survival of patients is only 1-2 months,while treated with whole brain radiotherapy,stereotactic radiotherapy and surgery,the survival of patients is prolong significantly. But for single metastasis and multiple metastases, the treatment strategies are different.The optimum treatment needs further research. On the base of prolong the patients＇ survival, preserving the patients＇ cognitive function is also important.
