Abstract
Purpose of Review
This review article seeks to summarize the existent literature regarding the use of anthracyclines (specifically doxorubicin) in the treatment of early-stage breast cancers, reviewing the clinically significant side effects of said therapy, and discussing new tools to risk stratify patients.
Recent Findings
The 2010 Early Breast Cancer Trialists’ Cooperative Group meta-analysis again found anthracycline-containing regimens to improve outcomes, while the ABC Trials have shown the superiority of regimens including doxorubicin versus regimens with docetaxel and cyclophosphamide alone in early-stage breast cancer. New risk stratification tools—such as Oncotype DX®—are helping oncologists decide which patients may be able to avoid chemotherapy.
Summary
Sequential doxorubicin/cyclophosphamide therapy, followed by treatment with docetaxel, improves outcomes in nearly all early-stage breast cancer, with the notable exception of Her2+ disease. Newer risk stratification tools allow better risk/reward calculations in which patients may be able to avoid anthracycline-based chemotherapy and its significant side effects.
