title: Combination chemotherapy with bleomycin, cyclophosphamide and dactinomycin for the treatment of osteogenic sarcoma.
abstract: Thirteen patients with osteogenic sarcoma were treated with multiple drug chemotherapy consisting of bleomycin, cyclophosphamide and dactinomycin. The dosage schedule used was: bleomycin 12 mg/m2/day, cyclophosphamide 600 mg/m2/day, and dactinomycin 450 microgram/m2/day. All drugs were given intravenously for two consecutive days. Treatment was repeated every 2 weeks. Toxicity included severe nausea and vomiting (managed with antiemetics and intravenous hydration) and manifestations of bone marrow depression. Of 13 patients, eight were previously treated with high dose methotrexate with citrovorum factor rescue, cyclophosphamide and Adriamycin. Of these eight, three patients had objective evidence of tumor regression (37.5%). Five of five previously untreated patients had objective evidence of tumor regression. The overall response rate in osteogenic sarcoma patients to BCD was 61.5%. The combination of BCD appears to be more active against osteogenic sarcoma than cyclophosphamide alone or Adriamycin alone. The relative safety with which BCD can be administered makes this combination a valuable adjunct to high dose methotrexate with citrovorum factor rescue and Adriamycin in the treatment of osteogenic sarcoma.
