High-Risk Chronic Lymphocytic Leukemia Complicating the Course of Imatinib-Treated Chronic Myeloid Leukemia: Successful Disease Management With Dual Tyrosine Kinase Inhibition

Abstract

The coexistence of chronic myeloid leukemia (CML) and chronic lymphocytic leukemia (CLL) in the same patient is exceedingly rare, with only a few cases reported in the literature. Here, we report a patient with CML who, having achieved a major molecular response with imatinib, subsequently developed CLL, which necessitated the concomitant administration of ibrutinib.

Keywords: chronic lymphocytic leukemia; chronic myeloid leukemia; tyrosine kinase inhibitors.
