ABSTRACT: Alectinib is a selective Anaplastic Lymphoma Kinase (ALK) tyrosine kinase inhibitor used as standard therapy for ALK-rearranged lung adenocarcinoma. Hemolytic anemia is considered a rare but significant adverse event of alectinib. Here, we report the case of a 78-year-old female with advanced ALK rearrangement-positive lung adenocarcinoma who developed grade 4 drug-induced hemolytic anemia after receiving alectinib as first-line therapy. We discontinued alectinib treatment and switched to brigatinib. As a result, anemia improved without recurrence of lung adenocarcinoma over one year.
