Concentrations of doxorubicin and its metabolites in human autopsy heart and other tissues.

Abstract

Overall, the results suggest that the much greater tendency to develop doxorubicin toxicity in heart than in other types of muscle may be due to a propensity of cardiac muscle to accumulate doxorubicin. The results also suggest that doxorubicinol may play a role in doxorubicin cardiac toxicity, and that doxorubicin may be gradually converted to doxorubicinol in human tissues.
