Chemotherapy that includes a drug from the class of chemotherapy agents called anthracyclines, which includes doxorubicin (Adriamycin®), daunorubicin (Cerubidine®), epirubicin HCL (Ellence®), or mitoxantrone (Novantrone®--a drug very similar to the anthracyclines). These drugs interfere with cell growth.
A common example of an anthracycline-based chemotherapy regimen for breast cancer is CAF (cyclophosphamide, doxorubicin, 5-fluorouracil), CEF (cyclophosphamide, epirubicin, 5-fluorouracil), or AC (doxorubicin, cyclophosphamide).
Chemotherapy for newly diagnosed breast cancer usually includes 2 to 3 drugs from different types or classifications of agents. Chemotherapy for recurrent breast cancer may also include several drugs from different classifications or may simply be a single drug depending on the individual circumstances, medical history, and doctor's evaluation and treatment decision.
