title: Mitoxantrone: a replacement for doxorubicin?
abstract: Doxorubicin (Adriamycin) is an unquestionably effective anticancer agent for many types of tumors, including advanced breast cancer. However, cardiotoxic effects of the drug have limited its use. Methods of reducing or preventing doxorubicin-induced cardiotoxicity have been suggested, including an investigational doxorubicin analog, mitoxantrone ( Novantrone ). Mitoxantrone was developed to reduce the cardiotoxicity associated with doxorubicin while maintaining effective antitumoral effects. Initial reports suggested that mitoxantrone might lack cardiotoxic potential; however, recent studies indicate that the drug can produce adverse cardiac effects (congestive heart failure), perhaps with similar frequency to that observed with doxorubicin. It is doubtful that mitoxantrone will be a significant advance over doxorubicin if direct comparative studies reveal a similar incidence of cardiomyopathy.
