[High-dose combination chemotherapy with autologous bone marrow transplantation in breast carcinoma]

Twelve patients with breast carcinoma were treated with high-dose combination chemotherapy supported by autologous bone marrow transplantation (ABMT). Seven of them had advanced metastatic disease and received 12 cours of A treatment, response rate (CR +PR) was 71.5% (CR: 1, PR: 4, NC: 2 and PD: 0) and it should be noted that all 4 patients who had received adriamycin 150 mg+5-fluorouracil 1,500 mg divided in two consecutive days or equivalent high-dose of other chemotherapeutic regimen responded (CR: 1 and PR: 3). To the therapy Five other patients received ABMT-supported adjuvant chemotherapy because of high risk of recurrence. One of them died of unrelated cause and other 4 are free of disease at 11, 14, 17 and 17 months following this treatment. A major toxicity was of myelosuppression and nadirs of neutrophils were 100-1,800 on days 9-19 (median: 400 on day 12), neutrophils recovered rather rapidly to levels of greater than or equal to 1,000, greater than or equal to 1,500 and greater than or equal to 2,000 by day 15, 16 and 17, respectively. High-dose combination chemotherapy with ABMT seemed quite effective in advanced breast carcinoma and a similar approach in adjuvant setting has also been suggested.
