Background and objective One of the most often distance metastasis site of non-small cell lung cancer (NSCLC) is brain and the standard treatment of brain metastasis was radiotheraphy including whole brain irradiation (WBI) and stereotactic radiotherapy (SRT). It has been reported that epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) had the active response in brain metastasis of lung cancer. In the present study, we reported one case of EGFR 19el in cerebrospinal fluid tested by ARMS got partial response given erlotinib. Methods Cerebrospinal fluid was collected through lumbar puncture, then cast-off cells and EGFR mutation was analysed. Erlotinib was given with dose of 150 mg, qd. Objective response was evaluated by Response Evaluation Criteriation in Solid Tumours (RECIST) v1.1 and adeverse events were evaluated according to Common Terminology Criteria for Adverse Events v4.0 (CTC AE v4.0). Results Heterocyst cells were found in cerebrospinal fluid and EGFR mutation was tested as 19del. The patient achieved partial response (PR) of brain metastasis and the effective response in lung was stable disease (SD) after 4 weeks of erlotinib. The progression-free survival (PFS) and overall survival (OS) of brain metastasis was 10.5 months and 11 months respectively. The main adverse event was rash (Grade I). Conclusion It was feasible to test EGFR mutation in cerebrospinal fluid and the combination of erlotinib with chemotheraphy would be an appropriate choice to those lung cancer patients who had brain metastasis harboring EGFR sensitive mutation. © 2015, Chinese Journal of Lung Cancer.

Background and objective: Distant metastasis was common in lung cancer, especially patients with bone marrow metastasis had poor prognosis and there were few effective methods. Crizotinib had been confirmed to be used in anaplastic lymphoma kinase (ALK) positive lung adenocarcinoma, but the efficacy in lung cancer with bone marrow metastasis was unknown. In the present study, we reported one case of ALK-positive lung adenocarcinoma with bone marrow matastasis given crizotinib treatment, the safety and efficacy was summarized. Methods: ALK fusion was tested by fluorescence in situ hybridization (FISH). Crizotinib was given with dose of 250 mg, bid. Objective response was evaluated by Response Evaluation Criteriation in Solid Tumours (RECIST) v1.1 and bone marrow response was evaluated by bone marrow puncture and biopsy. Adeverse events were evaluated according to Common Terminology Criteria for Adverse Events (CTC AE) v4.0. Results: The patient achieved partial response (PR) after 6 weeks of crizotinib, especially the objective response of bone marrow metastasis was complete response (CR). The patient stopped crizotinib because of pneumonia. The progression free survival (PFS) and overall survival (OS) was 20 weeks and 22 weeks respectively. Conclusion: Crizotinib could be an effective method for ALKpositive lung cancer with bone marrow metastasis and showed good tolerance. © 2015 Chinese Journal of Lung Cancer. All rights reserved.
