For 17 patients with bone and soft tissue sarcoma, 32 bolus and maintenance infusions of high-dose methotrexate (MTX) were performed to induce rapid elevation of plasma MTX concentration and to maintain it. At the doses of 200-300 mg/kg, plasma MTX concentrations were measured by enzyme assay. It needed four hours to reach the steady state by five hours'(More)
