Continuous cisplatin infusion in combination with vincristine and high-dose methotrexate for advanced osteogenic...

Fifteen patients with metastatic osteogenic sarcoma (OS) were treated with a combination of Vincristine (1.4 mg/m2), high-dose Methotrexate (8 g/m2), and Cisplatin (120 mg/m2 as a 72-h continuous infusion). The overall response rate was 66% [5 complete response (CR) and 5 partial response (PR)]. Four of the six patients not previously treated had a CR. Toxicity from this regimen was moderate and never life-threatening. In no case was impairment of the renal function observed, and the clearance of high-dose Methotrexate was never delayed.
