  • Title: Chemotherapy of osteosarcoma.
    Author: Sinks LF, Mindell ER.
    Journal: Clin Orthop Relat Res; 1975 Sep; (111):101-4. PubMed ID: 1057462.
    Abstract:
    Recent advances in the use of chemotherapy for treatment of osteosarcoma have altered out pessimism in this disease. Results are presented from 3 groups of investigators using different agents as adjuvant chemotherapy following immediately upon amputation of the primary. The Roswell Park Memorial Institute began a regime, immediately after amputation, of adriamycin 30 mg/M2 for 3 doses and given every 4-6 weeks. This study was subsequently expanded in a cooperative group (ALGB) and the results on 20 patients analyzed. At 19 months approximately 75 per cent are free of any pulmonary metastases compared with 10-25 per cent expected from amputation alone. Similar results have been obtained by other Centers using different chemotherapeutic agents. In Boston Children's Hospital high dose Methotrexate with citrovorum factor is used. In 12 of these patients local control of the primary by surgery was obtained and of these only 1 developed pulmonary metastases during an observation time of 23 months. At the M. D. Anderson Hospital multi-drug combinations were used including Cyclophosphamide, Vincristine, L-Phenylalamine Mustard and Adriamycin. They reported a survival rate of 55 per cent (10 out of 18). All of these neoplastic agents have toxic side effects but when carefully used these effects are minimized and the quality of life is quite good. Many questions must be answered by future controlled long term follow-up studies.
