A 61-year-old man was diagnosed positive for anaplastic lymphoma kinase (ALK) rearrangement lung cancer (cT4N2M1a Stage IV) and given platinum combination chemotherapy. Improvement was noted, but tumors subsequently increased. Crizotinib was started, and primary tumors of the lung were reduced, but neutropenia was gradually appeared and worsened. Crizotinib was stopped. The tumors increased, and alectinib was started, but it was ineffective. Alectinib was changed to ceritinib, and a chest CT examination showed remarkable improvement. This case suggests that ceritinib is effective in some patients with ALK-positive adenocarcinoma previously treated with alectinib.
