title: High-dose methotrexate with leucovorin rescue plus vincristine in advanced sarcoma: a Southwest Oncology Group study.
abstract: Twenty-six evaluable patients with advanced soft tissue and bony sarcomas refractory to chemotherapy were treated with vincristine plus high-dose methotrexate and leucovorin rescue. A 14% response rate was observed among 14 patients presenting with refractory soft tissue sarcomas. No responses were observed among 12 patients with bony sarcoma. Toxic reaction with nausea, vomiting, nephrotoxicity, and myelosuppression was manageable. While this study did demonstrate activity of this regimen in doxorubicin-refractory patients, the duration of the responses was relatively brief. Thus, the clinical utility of such a regimen is questionable.
