    Author: Kotz R, Leber H, Ramach W, Arbes H, Wolf A.
    Journal: Wien Klin Wochenschr; 1977 Jul 15; 89(14):474-9. PubMed ID: 70889.
    Abstract:
    Since January 1976 high-dose methotrexate (HDMTX) therapy has been used in the management of patients with osteogenic sarcoma at the Orthopaedic Department, University of Vienna. 7500 mg MTX/sqm body surface is administrated in a four-hour infusion with citrovorum factor rescue. This therapy is combined with dactinomycin, adriamycin, bleomycin, cyclophosphamide and vincristine in a multi-drug chemotherapeutic program as a prophylactic regimen after surgical treatment of the primary tumour, as well as in the management of metastases. So far, 12 patients have received a total of 46 infusions with HDMTX at montly intervals (6 patients already had widespread metastases). The use of several precautions such as adequate hydration 3 l/sqm body surface fluid), systematic alkalinization of the urine and regular control of the serum MTX level renders HDMTX therapy less hazardous. Five out of the 46 infusions were followed by mild toxic reactions consisting of mouth ulceration, fever and/or bone marrow depression. One out of the 6 patients with metastases and 5 out of the 6 patients receiving HDMTX as a prophylactic measure are without evidence of disease at present. In view of the short observation period, this report is limited to clinical observations only.
