Abstract

Purpose: To investigate the tolerability and impact on progression-free and overall survival of two consecutive cycles of high-dose chemotherapy (HDC) with autologous bona marrow transplantation (ABMT) in patients with previously untreated metastatic breast cancer. Patients and Methods: Twenty- eight patients received conventional-dose induction therapy (ITx) followed by a planned two cycles of HDC with ABMT. Median age was 45 years (range, 34 to 60 years). Sites of disease were bone (seven patients), visceral (three), soft tissue (11), multiple (six), and CNS (one). The ITx regimens of cyclophosphamide, Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH), methotrexate, fluorouracil, prednisone, and tamoxifen (CAMFTP) (three patients); fluorouracil, doxorubicin, and cyclophosphamide (FAC; 11 patients); cyclophosphamide, methotrexate, and fluorouracil (CMF; four patients); or doxorubicin or mitoxantrone/cyclophosphamide (10 patients) were given to maximum response (three to five cycles). HDC was cyclophosphamide 6 g/m2, carboplatin 2 g/m2, and etoposide 625 mg/m2 with ABMT. Results: Of 28 patients, 24 received two (86%) cycles of HDC. Four received only one cycle due to persistent toxicity from course 1 (one patient), no response to course 1 (two), and death on course 1 (one). Grade 3 to 4 nonhematologic toxicities included mucositis (in one or both cycles in 21 of 28 patients; 75%), diarrhea, nausea, and vomiting. Reversible peripheral neuropathy was seen in 15 of 28 patients and was severe in one. Documented infections were seen in 19 of 52 cycles. There was one transplant-related death. Six patients were converted from partial remission (PR) to complete remission (CR) with HDC; two of 24 patients (8%) were converted from PR to CR with the second cycle of HDC. Progression-free survival rate is nine of 28 patients (32%) with median follow-up of 23 months (range, 13 to 36+ months). Eighteen of 28 patients (64%) have progressed at 1 to 17 months from ABMT. Conclusion: Two cycles of HDC with ABMT was well tolerated with a high response rate in patients with metastatic breast cancer. The importance of the second cycle of HDC in this population is unclear.
