Design of CALGB 9741
The CALGB 9741 trial tested both sequential versus concurrent chemotherapy administration and a conventional dosing interval versus a dose-dense interval. 2,005 women were randomly assigned to one of four arms:
Arm 1: Ax4
Tx4
Cx4 q 3 weeks (conventional interval, sequential administration)
Arm 2: Ax4
Tx4
Cx4 q 2 weeks with filgrastim (dose-dense interval, sequential administration)
Arm 3: ACx4
Tx4 q 3 weeks (conventional interval, concurrent administration)
Arm 4: ACx4
Tx4 q 2 weeks with filgrastim (dose-dense interval, sequential administration)
A = 60mg/m2 doxorubicin, T = 175 mg/m2 paclitaxel over 3 hours, and C = 600mg/m2 cyclophosphamide. Tamoxifen was given after chemotherapy. The median age of the patients was 50 years old. the median number of positive nodes was 3, and 10 or more nodes were present in 12% of patients. About 67% of the patients were estrogen receptor-positive.
