In order to reflect the progress in the treatment worldwide timely, and further improve the level of standardized treatment of lung cancer with brain metastases in China, Chinese Association for Clinical Oncologists and Medical Oncology Branch of Chinese International Exchange and Promotion Association for Medical and Healthcare organized experts to formulate "Clinical practice guideline for brain metastases of lung cancer in China (2021 version)" .肺癌患者脑转移发生率高、预后差、自然生存时间短。近年来，随着外科手术、放射治疗和内科治疗水平的不断提高，肺癌脑转移患者的治疗选择越来越多，生存时间得以延长。为了及时反映国内外肺癌脑转移治疗的新进展，进一步提高肺癌脑转移患者的规范化治疗水平，中国医师协会肿瘤医师分会和中国医疗保健国际交流促进会肿瘤内科分会组织专家编写了《肺癌脑转移中国治疗指南(2021年版)》，以供临床医师参考。.
