Adriamycin, dibromodulcitol, and mitomycin combination chemotherapy for patients with metastatic breast carcinoma previously treated with cyclophosphamide, methotrexate, 5-fluorouracil, vincristine, and prednisone

Abstract

Twenty-six evaluable patients with metastatic breast carcinoma previously treated with a combination of cyclophosphamide, methotrexate, 5-fluorouracil, vincristine, and prednisone (CMFVP) were treated with a combination of doxorubicin (Adriamycin), dibromodulcitol, and mitomycin (ADM). Four patients (15%) achieved complete remission, and 10 patients (39%) had a partial response. Five patients (19%) had stable disease, and seven patients (27%) experienced disease progression. The median time to disease progression was 10 months for responding patients (range, 4-44 months) and 5 months (range, 2-13 months) for patients with stable disease. The median survival duration was 15 months (range, 6-44+ months) for responders, 11 months (range, 2-27 months) for patients with stable disease, and 4 months (range, 2-41 months) for nonresponders. Two of the four patients with complete remission are alive and in continued remission at a follow-up of 44 and 40 months. Seventy-one patients with greater than or equal to two sites of metastasis responded, whereas 23% of patients with greater than or equal to three metastatic sites responded. Although higher responses were seen with soft tissue and osseous metastasis, responses were observed in all three sites of metastasis. This combination chemotherapy regimen with ADM is an effective second-line program for patients who have previously received CMFVP chemotherapy.
