Anthracyclines in Early-Stage Breast Cancer: Is It the End of an Era?

Abstract

Anthracycline regimens have been the mainstay of adjuvant care in breast cancer for >20 years. A growing body of clinical experience has uncovered an unacceptable rate of significant cardiac and leukomogenic toxicities. A systematic review of the literature was performed highlighting anthracycline- and nonanthracycline-based adjuvant regimens. The published data suggest that nonanthracycline alternatives are less toxic than anthracycline-containing regimens and equally, if not more, efficacious. Molecular predictors, such as human epidermal growth factor receptor 2 and topoisomerase II α, are further refining the optimal role of anthracyclines. With these new advances, the current role of anthracycline-based chemotherapy in early-stage breast cancer demands re-examination.
