Summary
The recent approval of anaplastic lymphoma kinase (ALK) inhibitors for the treatment of ALK-rearranged non-small cell lung cancer (NSCLC) has dramatically transformed cancer therapy. However, leptomeningeal metastases (LM) are frequent and often devastating complications of ALK-rearranged NSCLC, and treatment against LM remains challenging. Herein we report a case of a 19-year-old male diagnosed with ALK-rearranged NSCLC with LM. He experienced heavy treatment before introduction of alectinib therapy, which continued for approximately 5.5 years with marked efficacy. However, he experienced recurrence of a bulbar metastasis after discontinuation of alectinib. Reintroduction of standard-dose alectinib therapy resolved the lesion again. Our findings suggest that ALK-tyrosine kinase inhibitor therapy should be continued in patients showing a long-term complete response, unless intolerable toxicities are present, and that rechallenge treatment with alectinib may represent a therapeutic option for central nervous system metastases.
