Successful Dasatinib Treatment of Epidermal Growth Factor Receptor-Mutant Lung Adenocarcinoma and BCR-ABL1-Positive Chronic Myeloid Leukemia: A Case Report.

ABSTRACT: Dasatinib, a second-generation BCR-ABL1 tyrosine kinase inhibitor (TKI), inhibits multiple kinase pathways and is a promising anti-tumor agent for various solid tumors, including lung cancer. Herein, we report a patient with coexisting epidermal growth factor receptor (EGFR)-mutant lung adenocarcinoma and BCR-ABL1-positive chronic myeloid leukemia (CML). The patient received afatinib for a postoperative intrapulmonary recurrence of lung adenocarcinoma harboring EGFR exon 19 deletion. Tumor reduction was achieved with afatinib; however, dose reduction was required because of grade 2 diarrhea and skin toxicity. The reduced dose maintained a partial response. Thirty-one months after introduction of afatinib, he was diagnosed as having BCR-ABL1-positive CML a
