BACKGROUND: The prognosis of patients with stage III B breast carcinoma with metastasis to the apical axillary lymph nodes is poor despite adequate local control achieved by surgery and/or radiation therapy. This study evaluated the feasibility of a dose-intensive up-front chemotherapy regimen in this subgroup of patients.
PATIENTS AND METHODS: A preoperative chemotherapy regimen consisting of 3 courses of fluorouracil 500 mg/m2, dose-intensive epidoxorubicin 120 mg/m2 and cyclophosphamide 500 mg/m2 (DIE-FEC), was administered at 21-day intervals without hematopoietic growth factors to 31 patients with apex-positive disease. All patients were below 60 years of age and none had had prior chemotherapy or radiotherapy.
RESULTS: Seven patients achieved clinical complete responses (23%), and 21 achieved clinical partial responses (68%); three patients had stable disease (10%), one of whom had only ductal carcinoma in situ at histopathologic evaluation, which suggested an additional response to therapy. The major toxicity was moderate bone marrow suppression with a median WBC nadir of 1650/microliters (range 500-4600). Other toxic effects were mild.
CONCLUSION: DIE-FEC is well-tolerated and highly effective as up-front chemotherapy in relatively young patients with high-risk breast cancer, with a 90% (CI 74%-98%) clinical objective response rate.
