Resumen
Fecha de inicio: 1 de febrero de 1994
Fecha en la que se inscribió al primer participante.OBJECTIVES: I. Evaluate the efficacy of dose intensive, sequential adjuvant chemotherapy with doxorubicin, paclitaxel, and cyclophosphamide in patients with stage II/III resected breast cancer. II. Evaluate the toxicity of this regimen in these patients. OUTLINE: All patients receive sequential chemotherapy regimens consisting of 3 courses each of doxorubicin, paclitaxel, and cyclophosphamide on a schedule of one course every 14 days. Following completion of chemotherapy, patients who underwent breast conservation surgery receive radiotherapy. Mastectomy patients with 10 or more positive nodes or with T3-4 tumors are also eligible for delayed radiotherapy. Patients who are hormone receptor positive (or whose receptor status is unknown) are treated with oral tamoxifen for 5 years, beginning after completion of all other therapy. Patients are followed every 3 months for 2 years, every 6 months for 3 years, then yearly. PROJECTED ACCRUAL: At total of 90 patients will be entered.
