Study characteristics | ||
Methods | Accrual dates: not reported Sample size: 68 USA Randomisation method: not reported Baseline comparability: not reported | |
Participants | Female % first line not reported unclear % metastatic breast cancer (MBC) (72% had visceral dominant disease) Age and ethnicity not stated | |
Interventions | AC vs CFP vs CAF (+/‐ calusterone)
Arm 1: (AC) doxorubicin + cyclophosphamide
Arm 2: (CFP) cyclophosphamide + 5‐fluorouracil + prednisone
Arm 3: (CAF) cyclophosphamide + doxorubicin + 5‐fluorouracil Ahmann 1976a = AC vs CAF |

Outcomes | Regression (defined as ≥ 50% reduction in tumour mass) Mean response duration Toxicity | |
Notes | Abstract only available Reports on 68/68 randomised patients Toxicity related death not reported Doses of the same chemotherapy agent are reduced in the addition of a drug arm | |
