Herein, we report the case of a non-smoking 36-year-old female patient who was diagnosed with right lung adenocarcinoma in 2005 (cT1N3M0, IIIB) and received definitive chemoradiotherapy. The patient achieved a partial response, and her disease remained under control for 8 years. However, in May 2013, the patient was diagnosed with brain metastasis and underwent subsequent surgical resection, followed by postoperative brain radiotherapy and chemotherapy. Postoperative pathology confirmed ALK gene rearrangement, and next-generation sequencing performed in 2020 identified the EML4-ALK variant as variant 1. After progression-free survival lasting 4 years, new metastatic lesions were found in the patient’s right lung, and she was administered crizotinib for 20 months. Due to a suspicious recurrence in the intracranial surgical margin area, as well as an unbearable gastrointestinal reaction to crizotinib, alectinib was later adopted. At the 7-month follow-up, positron emission tomography/com..... READ ARTICLE
