Four Versus Six Cycles of Cyclophosphamide/Doxorubicin or Paclitaxel in Adjuvant Breast Cancer


Cyclophosphamide And Doxorubicin (CA) (4 VS 6 Cycles) Versus Paclitaxel (4 VS 6 Cycles) As Adjuvant Therapy For Breast Cancer in Women With 0-3 Positive Axillary Lymph Nodes:A 2X2 Factorial Phase III Randomized Study


Drugs used in chemotherapy, such as cyclophosphamide, doxorubicin, and paclitaxel, work in different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. It is not yet known whether giving cyclophosphamide together with doxorubicin is more effective than giving paclitaxel alone in treating breast cancer.


This randomized phase III trial is studying cyclophosphamide and doxorubicin to see how well they work compared to paclitaxel in treating women with invasive breast cancer.
