"Classical" CMF versus a 3-weekly intravenous CMF schedule in postmenopausal patients with advanced breast cancer. An EORTC Breast Cancer Co-operative Group Phase III Trial (10808).

The "classical" CMF (cyclophosphamide/methotrexate/5-fluorouracil) schedule was compared with a modified 3-weekly intravenous CMF schedule in postmenopausal patients with advanced breast cancer, as concern had arisen as to whether the classical schedule was the optimal way to give these drugs. The response rate with classical CMF was 48% compared with 29% for intravenous CMF (P = 0.003). Response duration was similar at 11 months, but survival longer for the classical schedule (17 versus 12 months, P = 0.016). We conclude that classical CMF is the superior regimen and attribute this to the higher dose intensity achieved.
