目的：探讨影响肺癌脑转移综合治疗的预后因素及提高生存质量的可能性。方法：对８３例肺癌脑转移患者采用综合治疗。放疗剂量（全脑）２５～３８Ｇｙ后缩野瘤床追加１５～２５Ｇｙ。结果：手术切除加放疗的中位生存期１２个月，１年生存率为５０％，均显著优于其它各组（Ｐ＜０．０５）。结论：肺癌脑转移采用手术加放疗的效果较好。 Objective: To explore the prognostic factors and improve the quality of life of comprehensive treatment for brain metastases of lung cancer. Methods: Comprehensive treatment was performed on 83 patients with brain metastases from lung cancer. Radiotherapy dose (whole brain) 25 ~ 38Gy shrinking tumor bed plus 15 ~ 25Gy. Results: The median survival time of surgical resection and radiotherapy was 12 months. The one-year survival rate was 50%, which was significantly better than other groups (P<0.05). Conclusion: The effect of surgery and radiotherapy for brain metastases from lung cancer is better.
