Early imatinib mesylate-induced hepatotoxicity in chronic myelogenous leukaemia

Abstract

Imatinib mesylate is the first molecule of targeted therapy in chronic myelogenous leukaemia inhibiting constitutively activated BCR-ABL kinase. There are no long-term follow-up studies of large sample sizes to assess the toxicity of the use of imatinib mesylate over 10 years. Several cases of hepatotoxicity, including fatal liver failure, have been associated with the long-term use of imatinib mesylate. We report here on a patient who experienced immediate dominant cholestatic damage of the liver and mild hepatocyte damage during imatinib mesylate therapy. This differs from most reports showing dominantly acute hepatitis with necrosis associated with the use of imatinib mesylate. Copyright © 2007 S. Karger AG.
