(A) Clinical timeline of patient, with major treatment indicated. The patient has been benefitting from immunotherapy for more than 19 months. (B) Chest computed tomography (CT) of the metastatic lung tumors before Nivolumab initiation (June 2018) and last time follow-up (January 2020). (C) Magnetic resonance imaging (MRI) before and after Nivolumab treatment.

After systemic chemotherapy, he turned to traditional Chinese medicine treatment, until the onset of brain metastases in the right frontal lobe and left basal ganglia in June 2018 (Figures 1B,C). August 2018, and magnetic resonance imaging (MRI) scans showed an increased lesion size and edema of the left basal ganglia, as well as multiple brain metastases (Figure 1C).
