Forty patients with metastatic breast cancer were treated with a new combination regimen consisting of cyclophosphamide, epirubicin, high-dose folinic acid and 5-fluorouracil (super-FEC). A major objective response was observed in 32 patients (80%). Among these, 11 patients (27%) experienced a complete remission. The median duration of response was 10+ and 12+ months for CR and PR, respectively. The most common side-effect was oral mucositis (Grade III = nine patients; grade IV = two patients), while haematological toxicity was virtually absent. Considering the high-risk characteristics of the vast majority of the enrolled patients (75% had dominant visceral disease), these preliminary results suggest that super-FEC has a powerful activity in poor-prognosis metastatic breast cancer with an acceptable degree of toxicity.
