Before the introduction of the taxanes into the management of breast cancer, the anthracyclines (and doxorubicin and epirubicin [Ellence] in particular) were considered the most active agents against this malignancy. The marked activity of single-agent taxanes suggested that their antitumor efficacy might match and perhaps exceed that of the anthracyclines. Several prospective randomized trials have confirmed these initial impressions. At intermediate doses (60 mg/m²), the activity of doxorubicin and paclitaxel (Taxol) was similar; at higher doses (75 mg/m²), doxorubicin appeared more effective. Conversely, docetaxel (Taxotere) was reported to be more active than doxorubicin in one trial.
