Breast Cancer: SWOG S0221 (Hematology Oncology Associates)

SWOG S0221: Phase III Trial of Continuous Schedule AC +G vs Q 2 Week Schedule AC, Followed by Paclitaxel Given Either Every 2 Weeks or Weekly for 12 Weeks as Post-Op Adjuvant Therapy in Node-Positive or High-Risk Node-Negative Breast Cancer.


The main purpose of this study is to compare the effects (good and bad) of two different treatments (or “regimens”) for breast cancer that is considered high risk. These two treatments include essentially the same drugs given in different ways and on different schedules. All of the treatments use standard, commercially available medicines that are known to be effective for treating breast cancer.
