Abstract
BACKGROUND: Lung cancer with brain metastasis had poor prognosis. Crizotinib had been confirmed to be used in ROS1 (C-ros oncogene 1 receptor tyrosine kinase) rearranged lung adenocarcinoma, but its efficacy in lung cancer with brain metastasis was poor due to the blood brain barrier. In the present study, we reported one case of ROS1 fusion lung adenocarcinoma with symptomatic brain matastasis, who was treated with brain metastases resection, crizotinib, and whole brain radiotherapy plus boost to residual brain metastasis. The safety and efficacy was summarized.Entities:
